Solar Company Ranking Methodology

The Cost and Benefits of Solar in Altadena

For many people considering switching to solar, the decision of which solar company to choose depends on prices. The cost and possible savings vary depending on some important factors such as:

  • System size and type: Some models are more costly than others, so the one you want to get can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly 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. Not including incentives, you can save an average of $29,000 over 20 years with your solar panels, too.
  • How much you spend on energy: If your local utility rates are high, there's a better chance you'll get a higher return on your investment in solar panels. In Altadena, you can save an average of $71 a month on your electricity bills.
  • How much sunlight your roof gets: If your rooftop doesn't see much direct sunlight, your solar system won't be able to produce as much energy, which will give you lower savings on electric bills than a roof that gets lots of sunlight.

There are several wonderful benefits of solar even with the upfront cost of installation. It can help the Earth and your bank account. Additionally, it can increase the value of your home, leading to even more benefits if you want to sell your home later.

Solar Incentives in Altadena

Because solar power is better for the environment than traditional energy sources, there are several government incentives available to encourage its adoption. 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 your solar project cost when you file taxes, 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 read about the incentives you qualify for in Altadena.

Environmental Impact of Switching to Solar in Altadena

Installing solar panels can have a beneficial impact on the environment. But how much can installing solar panels actually affect the environment? If your household uses lots of energy, you can have an even greater impact on the planet by switching to solar power. 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 are concerned about the environment, the upfront cost of solar is a small price to pay for the offset carbon emissions.

EcoWatch's Altadena, CA Solar Company Rankings FAQs

What is the top solar installation company in Altadena?

The top local solar company in Altadena is Renewable USA, with a rating of 5.00 stars.

Are solar panels actually environmentally friendly?

Solar panels can be detrimental for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to dispose of 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 6.4 years, but your solar payback period will vary based on your utility costs. The more your typical power bill, the quicker your solar panel system will recoup your installation costs.

How often do solar panels need to be replaced?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
