Solar Panel System Design
At United Solar Electric, we want to provide you with a unique setup that’s tailored to your power needs and designed in a way that matches the location and space that you’ll be using. We are backed by a team of experienced designers that will work together with you to come up with the best solution for your situation.
The design aspect is one of the most important when looking at solar panels, batteries, and installation. Every home or business has its own power needs due to every person having different levels of energy consumption. That’s where our team of designers comes in to take into consideration every detail of your energy consumption to create a solar energy system, that will be able to cover what you want it to cover, whether it is a portion of your monthly bill, or getting you off the power grid for good.
Solar Power Design and Installation
After your system is designed, you’re happy with how the solar power system will support your energy needs, and the project is within your current budget, it’s the time to start thinking about installation.
Our top-notch technicians will come in once all materials are in place to install them and make sure to run the tests required to have everything ready to start providing the energy that your system will generate for your home or business.
We are proud to offer you a team of experienced technicians that will go above and beyond to make sure that the installation is done to perfection and that your system is working properly from day one.
Home Batteries
Solar power systems and panels are great to provide power from a couple of lights and items in the house to an entire building. It all depends on the type and size of system you end up installing. Having said that, there can be moments due to meteorological difficulties that your solar panels can’t provide the amount of energy that they were initially set to provide.
Problems that can affect your power output are storms, cloudy days, and any other phenomenon that is able to reduce the amount of direct sunlight hitting your panels. This does not mean that your panels will stop working, it just means that they will not have the optimal amount of sunlight to convert into usable energy.
You can counteract this problem by using batteries. Batteries can cover those gaps where the sun is either not available or it’s not fully exposed. A battery in your home can help you store that extra portion of the solar energy that you are not using at the moment to be used later when you need it if the solar panels are either not working properly for lack of sun intensity or at night.
Financing Options
There’s no need to pay out the entire design and installation of your solar panels in one go. At United Solar Electric, we understand that it’s not a possibility for everyone to do so. Our commitment to the environment and to provide great service to our customers has given us the opportunity to provide a financing servicer to you.
Financing will allow you to put in perspective what you can afford and what you really need. It’s understandable if you want to give solar power a try and are looking for a smaller system to make sure that it’s the right move for you, but you shouldn’t be holding back if you need a bigger system simply because you don’t have the liquidity for it.
That’s why we offer financing options for you to get the solar power system that you need. You can contact us today and request a quote from us and see if you qualify for financing your solar panels.

My wife and I purchased a new 19 panel solar system and Tesla Powerwall in mid 2025. The install was completed in October 2025. The crew and all of the people at United solar Electric were very responsive and professional. I would, and will do business with them again, (adding an additional battery).
PG&E was a problem. PG&E was very slow with providing PTO (permission To Operate). We did not receive PTO until end of May 2026, over 6 months from the date when system was operational. PG&E will need to upgrade transformer (December ???) before we can send greater that 2000 watts back to the system. Right now, we have conditional permission to operate, limiting output to PG&E to 2.2 KW.
To United Solar Electric's credit, they were with us the entire time dealing with PG&E and were just as irate with PG&E as we were.
Thank you, United Solar Electric!
Frequently Asked Questions About United Solar Electric
Is solar energy free?
Solar energy itself is free and renewable. Once you've covered the initial installation costs, the electricity generated by your solar panels won't cost you anything additional. While you'll need to perform occasional maintenance or repairs if damage occurs from external factors, the savings you'll realize from buying solar panels in Brentwood, CA far exceed ongoing electricity expenses. Solar panels are built to last, with many offering 25-year warranties and functioning effectively for 40-50 years according to the Motley Fool. Contact us today to begin your solar energy journey.
What are solar panels made of?
Solar panels are constructed with photovoltaic cells, commonly called solar cells. These cells use semiconductor materials to convert sunlight into usable electricity. In our experience, solar panels fall into two categories: photovoltaic panels that generate electricity from sunlight, and solar thermal panels that capture the sun's heat to warm water for residential heating and pools. When you're ready to purchase a solar panel in Brentwood, CA, contact the professionals at United Solar Electric with over 16 years of industry experience.
How efficient are solar panels?
Solar panel technology has advanced significantly over the years. The United States Department of Energy reports that residential solar cells typically convert approximately 20% of sunlight into usable electricity. Higher efficiency panels can reach 40% conversion rates, though these are generally designed for commercial applications. With expanding incentives for solar installation and ongoing technological improvements driven by market demand, the outlook for solar panels continues to improve as costs decline and efficiency increases. Reach out to our team today to purchase solar panels in Brentwood, CA.
Do you need direct sunlight?
While solar panels achieve maximum efficiency under direct sunlight, they'll still produce electricity on cloudy days and throughout winter months. Your solar panels in Brentwood, CA won't generate power at night, which creates a need for energy storage solutions. Battery systems address this challenge effectively. A properly designed solar power system with appropriately sized batteries can eliminate your dependence on alternative electricity sources. Contact our team at United Solar Electric to learn more about our comprehensive solar solutions.
Do I need permits?
You'll need to obtain a permit from your city and comply with any HOA regulations or community safety requirements in your area. We can assist you with the permitting process, guide you through the application procedures, and ensure all requirements are met before installation begins. To get started with our solar panels in Brentwood, CA, contact us today.
What's the required maintenance for solar panels?
Maintaining your solar panels is straightforward. The primary requirement is keeping the panels clean to ensure they absorb maximum sunlight. Proper panel placement and optimal angle can reduce the frequency of cleaning and servicing needed.
What are the cons of solar panels?
Solar panels have some drawbacks, though these can be minimized through careful planning and proper placement. Installing panels in shaded areas can reduce the electricity output below expected levels. Positioning solar panels too close to trees or tall vegetation creates two concerns: shade from these elements can decrease solar efficiency, and overhanging branches may scratch the panels, diminishing their performance.
Aside from free electricity, what else can solar panels provide?
As commercial and residential solar panel efficiency continues to improve, demand has grown accordingly. Installing a solar power system on your property can immediately increase its market value, as prospective buyers frequently view a functioning solar installation as a significant advantage. Solar panel installation also supports job creation in an expanding industry and benefits the environment by lowering carbon emissions. Some homeowners appreciate the modern aesthetic that solar panels add to their property's exterior. Are you ready to begin with solar panels near Brentwood, CA? Contact our team today. We're ready to assist you.
Does solar increase the value of my home after installation?
Yes, installing solar power increases your home's value by significantly lowering monthly energy expenses and providing homeowners with greater energy independence.
Is solar energy truly free after installation?
While solar energy itself is free as a renewable resource, there are initial installation and occasional maintenance costs. However, the savings on electricity bills and long lifespan of solar panels often outweigh these expenses.
What materials are used to make solar panels?
Solar panels are made of photovoltaic cells composed of semiconductors that convert sunlight into electricity. There are photovoltaic panels for electricity and solar thermal panels for heating water or pools.
How efficient are the solar panels offered?
Domestic solar panels typically convert around 20% of sunlight into electricity, with some commercial systems reaching up to 40% efficiency. Efficiency improves as technology advances and demand grows.

Are permits required for solar panel installation in Brentwood, CA?
Yes, permits from the city and compliance with community codes like HOAs are necessary. United Solar Electric assists customers with the permitting process before installation.
What maintenance do solar panels need?
Solar panels require simple maintenance such as keeping them clean and properly positioned to ensure maximum sunlight absorption, reducing the frequency of servicing.
What are potential drawbacks of solar panels?
