The Cost and Benefits of Solar in La Mesa
Even though solar panels can help save you a decent chunk of change on power bills over time, it's important to know the upfront costs. Some key factors that dictate how much it will cost to install a solar panel system on your home and how much money you could save over time are:
- Your household's power bills: Because of high monthly electricity bills in La Mesa, you could save about $920 a year with solar.
- Incentives: The federal solar investment tax credit currently lets you decrease your taxes by 30% of the project cost. Your state and city may also have incentives and rebates that you can use. In addition, you can save about $31,000 over 20 years on your utility bills, not including incentives.
- Average daily sunlight: Since La Mesa gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which impacts how much your electricity bills will be.
- average energy usage: The more electricity your home uses on average and the higher your current electricity bills are, the more likely you'll benefit from making the switch to solar.
Solar is a rewarding investment for most homeowners. You can generate your own power instead of paying for it from the grid and benefit from solar incentives and rebates, all while helping the Earth.

Solar Incentives in La Mesa
Although a solar power system is typically a large investment, it can save you a lot of money in the long term due to lower utility bills and government incentives. These incentives typically include cash rebates, tax breaks and/or solar renewable energy credits. They can lower the cost of installing solar panels by 30%, upwards of 50% depending on your location. Check out our article on solar incentives to learn what incentives are available to you.
Environmental Impact of Switching to Solar in La Mesa
There are a few big reasons why homeowners want to invest in solar energy: to help their wallet and the environment. But — how much exactly can you help by going solar? Switching to green energy for electricity in place of using nonrenewable energy is a good way to lower carbon dioxide emissions if you want to help reduce La Mesa's fair level of greenhouse gas emissions. Because solar panels don't release greenhouse gas emissions into the atmosphere when generating electricity, they're a good trade for traditional energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. If you want to do your part for the environment, you'll no doubt recognize that there are many advantages to adopting solar power other than just saving money on electricity. You can also help preserve the environment, which some would argue is more valuable.
