Factors that Affect Solar Panel Costs in Brentwood

Cost is often one of the most important factors for homeowners considering investing in solar. There are a few key factors that will push your cost above or below the average in Brentwood: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment

When it comes to estimating the cost of a solar energy system in Brentwood, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy consumption, which you can determine by looking at past energy bills. Your overall cost can increase by about $2,730 for each additional kilowatt you need. Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Brentwood, where sunlight is abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

Most solar installers in Brentwood have solar loans, which reduce the initial cost of installing a solar system. Though solar loans make adopting solar energy more accessible for Brentwood homeowners, they can also add to the total you pay for your system due to interest. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

The last key cost factor you should take into consideration is the installer you choose. Given the massive popularity of renewable energy solutions in Brentwood, you'll have many options to choose from, but each comes at various price points for labor and equipment. Additionally, some companies in Brentwood know more about local solar incentives and can help you take advantage of additional rebates or tax exemptions. Though, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

There are many companies to choose from in Brentwood, and some homeowners feel overwhelmed considering their options. Picking the right company for you can be challenging, so here are some tips to help you decide:

  • Warranty: Each company may offer different types of warranties that provide different kinds of coverage. A 25-year, all-inclusive warranty is the gold standard.
  • Contract: Though reading through a contract can take a lot of time, it's important to do it fully so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
  • Reputation: Solar panel companies that have great reviews from their customers and that have been operating for many years in most cases offer quality solar panel installation and expertise.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and energy needs. Even though there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you peruse their list of offerings before deciding.

EcoWatch's Brentwood, CA Solar Cost FAQs

What is the average cost of installing solar panels in Brentwood?

This is a difficult question to answer precisely, because the cost depends on many factors. Broadly speaking, it costs about $13,650 for a 5-kW system and $27,300 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or higher quality panels, or if you have above-average energy needs. Conversely, you can spend less if you choose a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Brentwood?

Leasing solar panels can be an appealing choice, as it usually comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Can you sell solar power back to the grid in Brentwood?

The majority of states offer net metering programs of some kind. Through these, you can either receive compensation for the extra power your system produces or or receive credits to put toward future electricity bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How many solar panels do I need to power my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
