Selling a Home With Solar Panels: What You Should Know

If you are considering investing in a solar installation in Murrieta, you may be wondering if solar panels will increase the resale value of your home.

While solar panels can certainly increase your home’s value, there are a couple of considerations you should make if you plan to sell a home with solar panels installed. Read on to learn how a solar system can affect your home’s resale value.

How does solar panels affect resale value?

According to The Office of Energy Efficiency and Renewable Energy, home buyers tend to see solar panels as home improvements and are usually willing to pay a premium of about $15,000 for a house with an average-sized  solar panel system. The extent to which solar panels can increase your home’s value depends on:

  • Your location: if you live in a sunny state like California where solar panels have become the standard, having solar panels installed on your home increases its value significantly.
  • Available incentives and rebates: the better the solar rebates and programs are in your home’s location, the better your chances of making a successful sale with solar panels. This is especially true in states with great net metering options.
  • The type of solar panels you choose: more expensive and efficient solar panels will boost your home’s resale value to a greater extent. This also holds true for appearance, as more expensive panels tend to be sleeker and more appealing to prospective buyers.
  • Ownership of the system: if you’re moving out of a home with solar panels that were leased, most buyers will request that you buy out the lease. If you own the solar panels, on the other hand, you’ll have a better chance of making a top-dollar sale.

Is it easy to sell a house with solar panels?

Selling a home with a solar system comes with a set of unique challenges, depending on your location and whether or not you own the system. Overall, you have a greater chance of making an easy sale with solar panels than without. This is in part because many buyers recognize the benefits of solar energy, both in terms of savings and the environmental impact. In fact, there is evidence to prove that homes with solar panels sell significantly faster than those that consume more energy.

As a seller, you can increase your own chances of making a top-dollar sale by presenting the benefits of solar panels to prospective buyers. While not all of them will be interested in “going green”, solar power is bound to be attractive to anyone who wants to gain energy independence and significantly decrease their energy bills. You can also emphasize the various net metering policies that will keep the energy costs even lower.

Moving Houses with Solar Panels: What’s the Procedure?

Solar panels are a fantastic way to decrease your energy bills and cut down on your carbon footprint. But what happens with your solar panels if you need to move? Can you have your solar system installed in your new home, or do you need to sell them with your old house?

Whether you’re relocating to or from the Murrieta area, your local solar panel installers can provide information to guide you through best courses of action to take.

What happens to solar panels when I move?

If you’ve decided to move from your home, your first instinct might be to bring the solar panels you invested in with you. The following are some considerations before deciding on what to do with your panels when you move:

  • Your new home’s location: If you’re moving locally, your solar installation company might be able to help you remove the solar panels and re-install them. For out-of-state moves, the costs and hassle of the process may not be worth it.
  • New location regulations: the electric company in your new location may have a different solar program, meaning you’ll have to contact them to get information on how to connect your system to the grid. You’ll also need information on tax incentives, permits, and net metering.
  • Property sun and shade: some houses are better suited for solar than others. If you’re relocating to a colder location from a sunny one or your new house has a lot of shade, selling your solar panels with the old home may be the best idea.
  • Warranty concerns: removing solar panels from the roof may void the warranty. This means that some solar companies won’t remove your panels, especially if you’re moving out of state.

Leaving your solar panels behind is an option

Selling your old home along with the panels can be the right choice for many homeowners. Since solar panels can boost the resale value of your property, they can make it easier for you to find the right buyers and sell your house faster. Not only that but you also won’t have to worry about damaging your roof during solar panel removal.

How much does it cost to relocate solar panels?

Relocating a solar system and reinstalling it requires quite a bit of time, effort, and money. The process may take about 3 to 4 months on average, as it involves steps such as signing paperwork, getting permits, and scheduling the move. Therefore, there are usually significant fees associated with relocating solar panels. The average costs tend to fall in the $4,000-$8,000 range, depending on the system’s size.

What Happens When a Solar Battery is Full?

If you’ve recently added battery storage to your solar system or plan on doing so, it’s only natural you’d have questions about how these batteries work. Solar panel installers from Murrieta to San Diego hear this question frequently: Where does excess solar energy go if the battery is full?

Solar batteries have a limited amount of energy they can retain in a single charge. But what happens when the battery is fully charged? Depending on your specific setup, the excess energy can move to several different places. Read on.

Where does solar go when batteries are full?

What happens to your excess solar energy will depend on the type of solar system you have.

Hybrid Inverters & the Grid

If you use a hybrid inverter system or have a solar system without battery backup, the produced energy will be either stored in the inverter or sent back into the grid for credit. Having your solar system connected to the grid is useful if you don’t want to worry about running out of power or wasting power when your batteries are fully charged. However, these types of systems can’t work during power outages, which can be a problem for many homeowners, especially those who live in areas with frequent natural disasters.

Off-Grid Systems

If your solar system is not connected to the grid, you are completely reliant on your setup to power the appliances in your home. This is a great way to store excess energy and use it during peak demand hours when energy rates are at their highest, as well as during power outages. However, this also means that you won’t be able to use the grid as backup any longer.

An off-grid solar system doesn’t have a back-up solution. When its batteries are full, the energy has nowhere else to go. Luckily, modern solar batteries designed for off-grid systems have much higher capacities than those designed for grid-tied systems. And since they can take in so much energy, they also tend to take quite a bit longer to charge. If your battery bank is properly sized for your energy needs, you’ll be quite unlikely to run out of storage at any point.

How do I know when my solar batteries are fully charged?

The method used for checking the charge of your solar battery will depend on the type of battery you have:

  • Lithium-ion batteries typically come with specialized charging systems and charge controllers. These devices are used both to charge the battery properly and measure its current charge level.
  • The charge of lead-acid batteries can also be checked using a charge controller, although many hydrometers and voltmeters can also be used. Additionally, you can also tell the charge of your battery by looking at the inverter, since many of them have led lights that indicate if the battery is charging or not.

Do I Need Battery Backup for My Solar Panels & Inverter?

Adding a battery to your solar panel system can be a great way to combat the perpetually increasing energy rates and protect yourself from power outages. But do you need a battery to use your solar panels and inverter? Will the costs of the battery outweigh its benefits?

As different homes have different energy needs, choosing between solar system options can be a challenging process. We want to explore and find solutions to make solar installation more efficient for homeowners in Murrieta, Riverside, Temecula, and the rest of Southern Riverside.

Can I use a solar panel and inverter without a battery?

The short answer to this question is yes, you can use your solar panel system without a battery. But, you have the opportunity to reap many benefits from choosing to add a battery backup.

While the advantages of solar, plus a battery installation are numerous, both may not be essential for everybody. Here are some situations in which a solar battery backup would be a great idea, and situations when simple rooftop panels will suffice:

1. Grid-tied systems 

During early morning and evening when solar production is lower, homeowners with solar panels often rely on the grid to supply them with the power they need. This setup is known as a grid-tied solar system, in which the grid serves as an energy backup system for the homeowners to use when solar production isn’t at its peak. 

Sticking with a grid-tied solar system is a good idea in states that use net metering. This means that you can send excess power back into the grid and earn credit for later use. However, after the implementation of the new Time of Use plan in which the rates are highest during peak demand hours, many homeowners have begun to switch to off-grid or hybrid systems. 

2. Hybrid systems 

If you want to avoid the exorbitant energy costs, you may want to consider getting a hybrid system that includes both a grid connection and its own battery bank. A hybrid inverter essentially combines a battery inverter and a solar inverter in one unit. This type of system enables you to store the energy produced during peak hours for later use without needing a separate battery. However, hybrid inverters can’t function during power outages. In these situations, you will have to rely on the grid to draw power. 

3. Off-grid systems 

A solar plus battery system would be the best idea for homeowners who: 

  • Live in regions where the power grid is unreliable or nonexistent 
  • Live in areas with a lot of power outages and natural disasters 
  • Want to be fully independent from the grid 

If you want to be able to use your own solar energy even during black-outs and low production hours, then a fully off-grid system is the way to go. This will enable you to reap significant savings and use 100% clean energy to power your home.

Which Appliances Can an Inverter Power?

The 2000 watt inverter is a convenient device which converts your panels’ DC electricity (Direct current power) into AC electricity (Alternating current power) to power your household appliances. So, what exactly can you run using a 2k watt inverter?

If you are unsure what size inverter your solar panels require, reach out to expert installers in Murrieta, Calif. for information and advice about your system. If you already own a 2000W inverter and plan to go off-the-grid, you may be wondering if it would be enough to power the appliances in your home. Continue reading to learn more.

Running and starting watts

In order to determine whether a 2k watt inverter will be able to power your appliances, be aware of the starting and running wattage of each appliance. The starting watts represent the surge of power needed to start the appliance. The running watts are the power the appliance needs to keep running. Appliances typically need more power to start than they need to run, meaning that the starting watts are usually higher than the running watts.

Some appliances, such as light bulbs, microwaves, toasters, and other heat or light producing devices usually don’t need additional starting watts. However, appliances that run on motors such as hair dryers will usually need extra power to kick off.

Determining Your Watt Requirements

So, how is this useful? You can add up the starting and running watts of your appliances once they are determined. This number will represent the minimum watt requirements for your solar inverter and help you determine if a 2k watt option would be sufficient for your home.

Appliances Powered by a 2k Inverter

A 2000W inverter can power a wide range of household appliances. Naturally, you may not be able to use all of these devices simultaneously, but use their running and starting wattage to determine which devices you can run at the same time. A 2k watt inverter can run:

  • Microwave (1000W)
  • Coffee maker (1000W)
  • Refrigerator (1200 W)
  • Toaster (1200W)
  • Computers (150W)
  • TV (250W)
  • Stereo (300W)
  • Ceiling fans (140W)
  • Electric heaters (1200W)

Will a 2000 watt Inverter Run a Refrigerator?

Considering a refrigerator is an essential device, it’s common to wonder if it can be powered by a 2k watt inverter with your solar system. The short answer is you can run a mid-sized fridge as long as it uses up to 1200 watts of starting power and is rated by ENERGY STAR.

However, a fridge is a unique device because it continually starts and stops while operating. So, the starting watts are not just an initial requirement. This is why it’s important to consider the overall wattage requirements of your fridge before deciding to run it on a 2k inverter.

Sizing Your Solar Panel Inverters

Solar inverters are a crucial part of any solar panel system. They are necessary for converting the direct current electricity (DC) produced by your solar panels into alternating current electricity (AC) suitable for powering household appliances.

When installing a solar panel system, the inverter size plays a crucial role. This is why you must rely on knowledgeable solar panel installers to help determine the right inverter size and system efficiency options for your home in  Murrieta, CA. Continue reading to learn all about solar panel inverters.

What Size Inverter Do Solar Panels Require?

Since your solar system produces and sends DC electricity to your solar inverter, it should be properly sized to handle the DC load and convert it into AC. Here are a couple of factors to consider when sizing a solar inverter:

Solar Inverter Size

The size of your solar inverter should generally be similar to your solar system’s DC rating. This means that you should get a 2000W inverter if for a 2kW solar system. Also, make sure to check the manufacturer’s guidelines on array capacity that should be paired with their inverters.

Your Location

The production of your solar system will also depend on geography. For instance, a country such as California has higher irradiance than, let’s say, Vermont, meaning that a system of the same size will produce more energy in California than in Vermont. In turn, your inverter size should be closer to the total wattage of the solar array if you live in an area with more sunshine, as it should be able to handle the maximum power output of the array.

Design and Site Specifics

The specifics of the installation process, especially those related to tilt and shading of your solar system, will also influence the amount of sunshine your solar panels receive, and in turn, also influence the proposed size of the inverter. A solar system which is installed at a sub-optimal angle or experiences more shade will potentially need an inverter of a smaller capacity.

How Many Inverters Is Needed for Your Solar Panels?

In order to convert DC electricity into AC electricity, your solar system will need only one inverter. However, If you have a solar battery added to your solar system, you will need to have an inverter that can also turn AC electricity back into DC which is then stored in the battery. There are two options for this:

  • Hybrid inverters: Also known as a battery-based inverter, a hybrid inverter combines a battery inverter and a solar inverter into one unified piece of equipment. It uses the DC power generated from the panels to charge the battery and converts the needed electricity for powering appliances into AC.
  • Separate inverters: You can also have two separate inverters for your solar battery and panels, one to convert DC into AC to power appliances or export to the grid, and another one to convert AC electricity into DC electricity to be stored in the battery.

Tips on Maintaining Lithium-Ion Batteries

Although lithium batteries have become the standard choice for storing solar-generated power, many homeowners are still doubtful about one thing: are lithium-ion batteries really maintenance free?

Homeowners looking for a hands-off approach to maintenance in their solar storage will surely find what they’re searching for in lithium-ion batteries. Still, the picture may not be as clear-cut as it may seem. In this article, the leading solar panel installers in Mira Mesa offer expert insight into lithium-ion batteries and their maintenance requirements. Read on!

Do lithium batteries go bad?

Thanks to the low maintenance requirements, high density, and falling costs of lithium-ion batteries, they have become the number one choice for solar storage in recent years. While they may not be the best fit where prolonged storage durations are needed, their perks definitely outweigh the drawbacks.

However, there is one thing to keep in mind when it comes to lithium-ion maintenance and that is the degradation rate. Just like any other lithium-ion battery, a solar battery will wear out after a certain number of charge/discharge cycles. Luckily, this degradation rate is usually planned for by battery manufacturers. In fact, many of them sell batteries that are rated to as many as 6000 cycles or more, which means that you won’t have to worry about your battery breaking down over the course of its lifespan (approximately 10 years or more).

How do I keep my lithium ion battery healthy?

Lithium-ion batteries are generally low-maintenance, although there are some slight differences between the two different lithium battery types. These are:

LFP batteries (lithium iron phosphate battery)

Lithium-iron phosphate batteries are designed to be long-lasting and safe for indoor applications, given that they don’t contain cobalt and pose no fire concerns. LFP batteries don’t require any maintenance, although the location of the installation may affect their functionality and performance.

Just like all lithium-ion batteries, LFP batteries have a BMS or battery management system which monitors the battery cells for state of charge, temperature, cycle life, and other parameters that can ensure proper performance.  The bottom line for LFP batteries is that they will be zero-maintenance as long as they are installed in suitable temperature ranges.

NMC batteries (lithium nickel manganese cobalt oxide)

NMC batteries are another safe and long-lasting option for solar home storage. The additionHow do I keep my lithium ion battery healthy? of manganese and nickel enables an NMC battery to store more energy than its competitors, and its battery management system ensures safe and efficient performance.

Just like other lithium batteries, NMC batteries require no maintenance. This is because their BMS monitors cell temperatures, voltages, and currents, and shuts down the entire system in the case of potentially dangerous operating conditions. This type of battery has no specific recommendations for winter usage, under the condition that the temperature ranges specified in the instructions are acknowledged. The LG Chem Resu is a good example of a quality NMC battery.

Solar Battery Costs: What You Should Know

Solar batteries are a relatively new technology that can bring a wide range of perks to solar panel owners. But is installing a solar battery worth it for you? Before you can determine whether including a battery in your solar installation would make sense, you should first learn all about solar battery costs in Mira Mesa.

In this article, we share useful information on solar battery costs and try to predict how battery prices are likely to develop in the near future. Keep on reading to learn if installing a solar battery is the right choice for you in terms of finances.

How much does it cost to install solar batteries?

Pricing is a crucial factor in determining if adding solar battery storage would be a good choice. There are two main ways you could think of solar battery costs:

  • Gross price: Modern solar batteries can cost anywhere from $5,000 to $7,000+.
  • Price per relative battery capacity: solar home batteries range from $400 to $750 per kilowatt-hour.

However, it is important to note here that the listed prices are for the solar battery only, not for the installation or extra equipment that may be needed. In general, the total cost of solar battery installation tends to fall in the $11,000 to $18,000+ range or  $800 to $1,300 per kWh.

Factors that influence solar battery costs

Some of the factors that may determine the exact cost of a solar battery include the material it’s made from and the amount of power the battery is able to give you. For instance, lithium-ion batteries tend to be more expensive than their lead-acid counterparts, as they generally deliver superior performance. Also, quality off-grid batteries are often more expensive than those designed for on-grid applications.

Another factor that may play a role is the presence of an inverter. Unless your solar battery comes with a specialized built-in inverter, one will have to be installed in order to manage the electricity flow from and to the battery. However, it is important to note that you won’t have to install an additional inverter if you already have one in your solar panel system.

Are solar batteries coming down in price?

Considering the fact that solar batteries are a newly developed technology, just like solar panels used to be decades back, it is safe to assume that solar battery costs are likely to drop in the years to come, too. In fact, the market for solar batteries has been booming in recent years, particularly because of the ever-increasing electricity prices and decreasing battery costs. Not only that but the high battery demand also means more competition, which is bound to drive down the costs significantly for everyone.

However, all of this does not mean that you should wait too long to get your solar battery storage – with the exorbitant peak TOU rates implemented in California, getting solar storage is definitely a sound financial decision in 2020.

Car Batteries vs. Solar Batteries: What Is the Difference?

Many homeowners wonder if it’s possible to use car batteries with solar panels. In order to answer this question, we have to understand the differences and similarities between solar and car batteries. 

Whether you wish to learn how to calculate battery capacity or learn the difference between car and solar batteries for your solar panels in Mira Mesa, CA, you’ve come to the right place. As the leading solar installers in the area, we are here to provide you with all the information you need to make the most of your solar system. Keep on reading. 

What is the difference between solar battery and car battery?

Most cars have lead-acid batteries, also referred to as SLI batteries. This is because car batteries have three primary functions: to Start, to Light, and to Ignite, thus SLI. This type of battery is designed to provide short electricity bursts in order to start the engine and power the car. 

An SLI lead-acid battery consists of two plates made from lead-dioxide submerged in sulfuric acid. The acid and lead-dioxide produce electrons by creating a chemical reaction. The electrons then move across the plates, generating electricity.  

In addition to SLI batteries, there are several other types of car batteries that belong in the following two categories: 

Wet cell 

Two types of batteries belong to this category: deep cell and the SLI batteries we’ve already mentioned. A deep cell battery, or a marine battery, is designed to produce long discharges of electricity instead of providing short bursts.


A VRLA or Sealed Lead Acid (SLA battery) is sealed in order to prevent the chemical reaction gases from escaping. There are two main VRLA batteries available on the market: AGM battery (absorbed glass mat battery) and the gel cell battery. 

Can you use car batteries for solarCan you use car batteries for solar?

Although solar batteries and car batteries have similarities, they are meant for different purposes. While car batteries need to be able to start a car’s engine by producing short bursts, they won’t necessarily be able to meet your solar needs. This is because solar batteries are typically deep cycle batteries, designed to produce long discharges of electricity instead of short bursts. 

Lithium-ion & lead-acid batteries for solar 

There are two main types of batteries suitable for solar systems. These are lead-acid and lithium-ion batteries. While lead-acid batteries can be used with solar panels, they tend to have lower depth of discharge and shorter lifespans than lithium-ion batteries. What’s more, they tend to gradually lose some of their capacity over time as they go through their charge/discharge cycles. 

To sum up, car batteries are not suitable for use with solar panels. Instead, you should always use a battery specifically made for solar energy use, and consider choosing lithium-ion batteries over lead-acid if you want a battery that offers highly reliable performance. Modern lithium-ion batteries are ideal for solar use, as they feature great discharge depths, fantastic efficiency, and longer lifespans.

How Many Solar Batteries Do I Need?

Determining the number of home batteries you need can be a daunting task. If the battery capacity isn’t sufficient for your home, you risk running out of power. But getting too many batteries is not much better either, as it adds unnecessary costs and maintenance to your solar system. 

However difficult it may seem, sizing your solar battery storage is an essential part of planning your off-grid solar system. Fortunately, you can rely on the leading solar panel installers in Mira Mesa, CA and its surroundings to help you determine the right number of solar batteries for your home. Read on. 

How many solar batteries are needed to power a house?

The size and capacity of your solar battery storage will depend on several factors specific to your particular situation. These are: 

1. Your energy consumption 

The energy consumption of your household is generally measured in kilowatt hours. In order to calculate the total consumption, you can either calculate the energy usage of all appliances in your household and add them up, or look at your electricity bills from the previous months to estimate your daily consumption. 

2. Days without sunshine 

The number of days your solar system will have to run without sunlight is a crucial factor in properly sizing your battery storage. For instance, if you live in a rainy or cloudy area, you will have to purchase a battery that has sufficient capacity to power your panels until the clouds clear away. 

This is known as days of autonomy: if your battery has two days of autonomy, that means that it can power your panels continuously for two days on a single charge. Most solar batteries fall into the 2-5 days of autonomy range. 

3. The battery you choose  

Different types of solar batteries have different characteristics and sizing requirements. In most cases, homeowners choose between lead acid and lithium-ion batteries. For the most part, lithium batteries tend to be more efficient and have a greater DoD (depth of discharge). 

This means that lithium batteries waste less power and allow you to use more of your battery’s capacity. For example, most lead acid batteries have a DoD of only 50% whereas a lithium-ion battery can boast a DoD of as much as 95%. 

How do you calculate solar battery capacityHow do you calculate solar battery capacity?

In order to properly size your battery, you will need the following information:  

  • How much energy you need on a daily basis 
  • How many days of autonomy the battery has to have 
  • The maximum battery power (DoD) 
  • The inefficiency factor 

Let’s say you want your 80% DoD battery to last for 3 days without charging and your daily energy consumption is 10 kWh. The calculation should go like this: 

  • 10 x 3 x 1.2 (80% DoD) x 1.05 (inefficiency factor) = 37.9 kWh 

This number represents the amount of energy you’ll need from your solar batteries. You can then divide this amount in watt hours with your system’s voltage (12, 24, or 48V) to get the amp hours (AH). Dividing this number by your battery’s rating will give you the number of batteries you should get for your home.
