There are many reasons why homeowners go solar, but improving the environment and cutting energy costs are the most common. Many people are aware that solar is a great home efficiency upgrade and are eager to reduce their carbon footprint while also improving property value.  

Why Choose Solar?

What Are The Benefits of Choosing Solar?

Save Money

Lower Your Bill and Save Money!

Lower your electric bill or eliminate it altogether! As of January 1st, 2019, the average PG&E bill that Californians received was $167.02, with many paying over $150. Solar panels allow you to utilize the sun’s energy instead of paying your local utility company for electricity, leading to lower electric bills. In some cases, your solar panels will actually give added energy back to the grid. At times, you may even receive a credit from your local utility company. As a homeowner, electricity costs can make up a large portion of your annual expenses. With a solar panel system, you’ll generate free power for your system’s entire lifecycle. Solar panels aren’t an expense. They’re one of the best ways to invest, with returns rivaling those of more traditional investments like stocks and bonds. Savings are immediate! And thanks to substantial electricity bill savings, solar paired with other energy efficient upgrades can max your solar savings. 

Save Money

Increased Value

Multiple studies have found that homes equipped with solar energy systems have higher property value and sell more quickly than non-solar homes. Due to progression in the solar industry, solar financing is now 100% transferrable at sale of home. Appraisers are increasingly taking solar installations into consideration as they value homes at the time of a sale. As homebuyers become more educated about solar, demand for properties equipped with solar panel systems will continue to grow. 

Solar Panels and Home Values

Solar Future

The sun is a near infinite source of energy and a key component of achieving energy independence in the United States. By increasing our capacity to generate electricity from the sun, we can also insulate our country from price fluctuations in global energy markets. 

Save Energy

There’s no denying that as a society, we use more energy than our environment can afford to give. Utilizing solar energy means you’ll be reducing your carbon footprint and giving back excess energy to the grid all while helping reduce the overall consumption of fossil fuel in your community. 

We Offer 100% Financing!

At SIG solar we believe that the cost of our equipment should never impact your ability to save! That is why we offer multiple financing options for all of our clients so that everyone has the opportunity to save big by going SIG Solar with 0 out of pocket.



With decades of experience spread throughout our company, we make sure to have the best of the best on our team so that you can feel confident that your solar needs will be taken care of in each step of the process.

SIG is a true father-son operation with Stephen Kerr and his sons Paul, Jared, and Aaron overseeing every part of the solar process. Solar Installation Group, Inc. started as a 3rd party installation company for solar sales companies across the US in 2013 doing residential, commercial, and agricultural solar projects.

We operate under our contractor’s license which has been active for over 40 years. After seeing what was lacking on the customer service side of the solar industry, and looking to bring the knowledge of sustainable energy back home to their local community, the Kerr family made the commitment to create a local, family-based company that has since developed into both a solar sales and installation company. SIG Solar prides itself on customer service, family values and bettering the community we live in.

We have been so overwhelmed by the love and support from our local communities, that it has only furthered our drive and mission to bring solar to every roof in California; including yours!

“SIG was amazing to work with! They did a great job, and had our Solar up and running within a couple of weeks of signing our contract. They were able to install the system in one day! They have great customer service, and are very reliable. They answered any questions we had, and made us feel very comfortable. I'm so glad we decided to choose SIG as our solar company!”

“The entire team was very friendly and helpful. They answered all of my questions before I made up my mind. Every aspect from my initial introduction by sales representative Jon-Michael to the PSA physical site assessment. Once I was sure I wanted their service, I was not disappointed. The installation crew were professional and responsive. They completed the job in one day and the inspection by the city passed within one week of installation. Very pleased with the Solar!”

  • Q. Are there incentives available for solar?

    A. Yes, this year there is a 26% Federal Tax Credit (FTC) Available. Unfortunately, 2019 was the last year of the 30% FTC.  In 2021 the FTC is scheduled to drop to 22%.
  • Q. How many panels do I need?

    A. That varies from Home to Home (or Business to Business) based upon total electrical usage, solar exposure, and position of the solar array.  Our Solar Energy Consultants can provide a customized proposal to your specific needs.

  • Q. How long will the installation take?

    A. Once you have gone SIG Solar the process starts immediately.  Depending upon the City or County Permit process, the average solar installation process takes 30-45 days.
  • Q. Does SIG Solar ever sub-contract solar installs?

    A. No, SIG Solar is a completely “In-House” company. We will never sub-contract out a solar installation.

  • Q. What time of the day do solar panels work best?

    A. The highest solar generation during the day is usually from 11am to 4pm. Days are longer in summer and shorter in winter and correspondingly, the amount of electricity generated through the same solar power system, in the same location changes with the seasons
  • Q. Do solar panels work in moonlight?

    A. The answer is a definite YES, because Moonlight is nothing but reflected Sunlight. Solar pv panels do convert moonlight to electricity. It can be used to power PV cells at a cost of 345:1, meaning, a panel that would normally produce 3450 W at high noon would produce only 10 W of power during the full
  • Q. Do you really save money with solar panels?

    A. One of the biggest advantages of installing residential solar panels is a 26% federal tax credit on the total cost of a system. ... The credit could save the average homeowner $5,000 or more (depending on the size of the system), according to EnergySage, a solar marketplace with a calculator to help estimate savings.
  • Q. Do solar panels hurt the resale value of your home?

    A. According to a nationwide study by the US Department of Energy's Lawrence Berkeley National Laboratory, resale values increase an average of $4 for each additional solar watt installed. This means that a standard 5kW system could increase your home's value by as much as $20,000
  • Q. How long do solar panels last?

    A. As a general solar industry rule of thumb, solar panels last about 25-30 years. However, this doesn't mean that they stop producing electricity after 25 years – it just means that energy production has declined by what manufacturers consider to be a significant amount
