The Cost and Benefits of Solar in El Cajon

Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to set up your panels. There are quite a few factors you should consider when determining how much it will cost and how much you can save, including:

  • Energy consumption: Installing solar panels may be an expensive option for households that don't consume a good amount of energy a month.
  • Average daily sunlight: Since El Cajon gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much your electricity bills will be.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $31,000 over 20 years with your system, too.
  • Your household's power bills: Because of high monthly power bills in El Cajon, you could save about $920 a year with solar.

So is buying solar panels worth it? Whether you hope to decrease your electric bills, greenhouse gas emissions or both, solar panels are a solid investment for many El Cajon homeowners.

Solar Incentives in El Cajon

There are lots of reasons why adopting solar power is beneficial. One of them consists of some government incentives you can take advantage of. Regardless of where you live, you can take advantage of the federal Solar Investment Tax Credit (ITC), which will let you claim 30% of how much you paid for your solar installation on your tax return, reducing the amount of taxes you owe that year. Plus, there may be some local incentives that stack with the ITC too. In our article on solar incentives, you can find out about the incentives you qualify for near you.

Environmental Impact of Switching to Solar in El Cajon

There are a few main reasons why people are considering solar energy: to help their wallet and the environment. A question many homeowners might be wondering about is how much can they really help protect the environment by going solar anyway? One thing to keep in mind is your overall carbon footprint. For example, if you spend lots of time commuting to work and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions. Once you go solar, your carbon emissions can be reduced by about 50 pounds a year. If you want to do your part for the environment, you'll no doubt get that there are many advantages to adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is priceless.
