Solar Company Ranking Methodology

The Cost and Benefits of Solar in San Diego

We get that for most homeowners, the choice to invest in solar rests on installation costs. Some important factors that influence how much it will cost to install a solar panel system on your home and how much money you could save over time include:

  • Your location: This affects how much sunlight your roof receives, which helps determine how many panels you need.
  • How much energy costs for you: The average household in San Diego shells out around $920 a year on energy use alone, so you could be looking at that much in savings.
  • The kind of solar panels you're planning on getting: Higher-efficiency panels are more highly priced, so that will determine your budget for your solar project.
  • Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 30% of the cost of installing your solar panel system from your federal taxes. Additionally, not including incentives, you can save about $31,000 over 20 years on your energy bills.

Because of solar panels now being cheaper than ever as well as local and federal solar incentives, they are a solid investment for many homeowners.

Solar Incentives in San Diego

Adopting solar power has plenty of considerable benefits. Not only can it help protect the planet, but you can also save a decent amount of money on your installation with various government incentives. These incentives mostly include cash rebates, tax breaks and/or solar renewable energy credits. They can reduce the cost of installing solar panels by 30%, upwards of 50% in some cases. You can learn about the incentives you can take advantage of in our article on solar incentives

Environmental Impact of Switching to Solar in San Diego

There are many reasons to trade traditional energy for solar power, like saving some money on electricity bills and helping to reduce your carbon footprint. But how much can installing solar panels actually affect the environment? A significant thing to be mindful of is your overall carbon footprint. For example, if your commute is very long, your footprint may be bigger, so adopting solar energy for your house can help offset that. In fact, if you make the switch to solar power, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year. For people who want to help the environment, the upfront cost of solar is a small price to pay for reducing your carbon footprint.

What is the most reputable solar installer in San Diego?

The best local solar company in San Diego is Renewable USA, with a rating of 5.00 stars.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Solar panel manufacturing requires a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take for solar to pay for itself?

Solar panels generally pay for themselves in about 5.8 years, but your solar payback period will vary depending on your utility costs. The more your typical power bill, the quicker your solar panel system will recoup your installation costs.

What is the best kind of solar panel?

There are three main types of solar panels: monocrystalline, polycrystalline and thin-film. In terms of efficiency and price, monocrystalline has the highest for both, then polycrystalline, and then thin-film. The best choice for you is highly influenced by your roof configuration, how much you're willing to spend and desired energy output.
