How much do solar panels cost in Brentwood, CA?
The average cost per watt of residential solar in California is $4/watt. For comparison, the national average is $3.70/watt.
Cost per watt is the total installed cost of a system, including taxes, divided by the size of the system in watts (DC). It includes the cost of hardware plus installation costs. Cost per watt is always the gross cost, before incentives. This means, at a minimum, you can take 30% off the price of the system in 2019 because of federal tax incentives.
The cost of a solar panel system for your house in Brentwood will depend on how much electricity you want to generate, which affects the size of the system you’ll need. The following is an example price estimate for a home solar panel system in Brentwood, with an electricity generation estimate based on the local climate and the following assumptions:
• 554 kWh is the amount of electricity that the average California home uses every month.
• 3.70 kilowatts is the size of the system you’ll need to generate 100% of this electricity from solar panels.
• 9 to 14 panels is what that translates to (depending on panel efficiency, which commonly ranges from 260 watts to 400 watts)
• Panels oriented due south and mounted on a shade-free roof at a 30° angle.
|Gross system price||$14,427||This is the price of your system plus taxes but before incentives, based on an average cost of solar in your state of $4 per watt.|
|Federal tax credit of 30%||$4,328||The most important solar incentive in the nation, the federal solar tax credit, gives homeowners 30% off the cost of their system in 2019. It drops to 26% next year. Read more|
|Net system price:||$10,099|

Can you save money with solar panels in Brentwood, CA?
Every year, that hypothetical Brentwood home solar system described above would produce about $1,974 worth of electricity. This is based on the California state average price of electricity of $0.18/kWh and the average local climate.
But that’s just a home with average electricity usage. You might need more or fewer solar panels, depending on how much electricity you want to generate. Also, shade matters a lot. If you have trees or buildings throwing shadows on your roof, that could reduce your solar production by a lot.
Houses in Brentwood with solar panels
According to our data from various local agencies, there are at least 3,689 homes in Brentwood that have solar panels installed. This means a lot of your neighbors have looked into solar and decided that it’s a smart choice for them. If you add up the total generating capacity of these solar panel systems, you get a total of 20,394 kilowatts of solar electricity that is being sent into your local electricity grid.
If you’re trying to decide if solar is right for you, this is good news. Having a lot of solar homes means that you will have more local contractors to choose from. You can also feel more confident about going solar, because many of your neighbors in Brentwood have already decided that solar is a smart choice for them.
Brentwood solar energy potential
If you want to know how much sunlight is available in your city for solar electricity generation, you need to know the Direct Normal Irradiance (DNI). DNI not only takes into account the hours of sunlight, but other variables such as cloud cover, airborne particulates (which cause haze), and precipitation.
The DNI for Brentwood is 6.65, which means that it has excellent solar potential.
In Brentwood, you’ll generate a lot of solar electricity throughout the year, which helps to shorten the amount of time is takes for a solar panel system to pay for itself.
In the continental United States, DNI ranges from about 3.0 to 8.5 kWh/m2/day. In the most northern parts of Alaska, the DNI reaches a low of 0.5.
A higher DNI means more sunshine and more electricity generation by
solar panels, but solar can be viable even with a lower DNI. For example, Germany has widespread solar PV, but a DNI of only about 2.5.
This DNI data comes from GEOS geostationary
satellite data and
NREL climate models.
In some climates, you’ll see a big difference in sunlight and solar electricity generation from summer to winter.
These charts show you what to expect in Brentwood.
Energy by Month (DNI)
The graph below estimates how much a 6 kilowatt south-facing solar panel system would generate in Brentwood.
Generation by Month (kWh)
A home solar energy system in Brentwood will have very little seasonal variation in power generation. A solar panel system in the peak month would produce 146% more electricity compared to the darkest month in winter. This is a very small difference between winter and summer solar energy generation versus most other location in the United States. This is good thing if you don’t have net metering, because it means that you will tend to send less excess electricity into the grid.

Solar panel lease companies in Brentwood
If you’re thinking about going with a solar lease or PPA, you should first read our guide to solar financing to make sure that you understand the pros and cons of a lease or PPA versus purchasing a system outright. In most cases, you will come out on top by buying your solar panels, even if that means taking out a loan.
That said, leases/PPAs continue to be popular, and they can be a good choice in some cases. There are several national solar installers that offer leases/PPAs, but not all of them operate in every state. Here’s a breakdown of some of the major solar installers that offer these types of contracts, and whether they operate in your state:

Looking for solar panel cleaning companies in Brentwood?
If you’re thinking about paying a company to clean your solar panels, think again.
Trying to get the maximum number of watts out of your solar array by keeping your panels squeaky clean isn’t worth it if you’re paying $100 or more per visit from a cleaning company.
In fact, rain is sufficient to keep solar panels clean for most people.
If you live in a dry and dusty area or frequently find bird poop or leaves on your panels, invest in some inexpensive equipment to take care of cleaning yourself. Read our guide to solar panel maintenance, which includes tips on solar panel cleaning and a some recommended cleaning equipment.

Average California electricity prices
Right now in California, the average price of residential electricity is about 18.31 cents per kilowatt hour. In comparison, the average price of electricity in the United States is about 13.34 cents per kWh.
This means that you are paying 37% more for electricity than the national average. That’s pretty expensive.
Higher than average prices like this are a good argument for going solar.
Regardless of what your electricity prices are, by adding solar panels to your house and generating your own electricity, you’re locking in your cost of electricity for as long as your system is working, which will protect you from future rate increases by your utility. Given that many panels come with 25 year warranties, this is an investment that can last a long time.
Keep in mind that the price of electricity varies by utility, sometimes by a lot. The table below lists the average price of electricity for utilities in California state. For current rates, check with your utility.

Historical California electricity prices, 2008 to 2017
The average price of residential electricity in California, over the past ten
15.86 cents per
This is 31% more than than the US average price of 12.07 cents per kWh. Because your state historically has had high electricity prices, there’s a good chance that prices will continue to be high in the future. This is a good argument for going solar.
Why is this important to know? Depending on the size of your system, owning
solar reduces or eliminates the effect of electricity price increases.
Historical California electricity prices (cents per kilowatt hour)
By looking at the trend in electricity prices over the past decade, you can get a better idea of whether high or low prices in your state are a recent change, or part of a long term trend. Because solar panels last a really long time (most come with 25 year power warranties), going solar protects you from future changes in electricity price. Basically, by paying for a system now, you can lock in your cost of electricity for two or even three decades.
Environmental report for California electricity
Depending on the type of fuel they use, power plants produce differing amounts of air pollution. This is measured as units of pollution per megawatt hour (mWh) of electricity.
For every mWh of electricity generated, California power plants produce on average:
- 216 kilograms of CO2, which is 53% less than the US average of
- 7 grams of SO2, which is 98% less than the US average of 411 g.
- 332 grams of NOx, which is 11% less than the US average of
In the power generation estimate listed above, The Solar Nerd calculator determined that an unshaded, south-facing 6 kilowatt PV system would generate about 10,782 kWh in an average year.
This means that putting a 6 kW solar panel system on your house would prevent 2,329 kilograms of CO2, 75 grams of SO2, and 3,580 grams of NOx from being emitted into the atmosphere.
The carbon offset of these solar panels would be about equivalent to planting 135 trees every year! (One deciduous tree left to grow for 10 years offsets 17.2 kg of CO2, according to the EPA.)
