Solar Company Ranking Methodology

The Cost and Benefits of Solar in Walnut
When picking a solar company, most homeowners or business owners wonder about the costs the most. There are quite a few factors you should take into consideration when trying to determine how much it will cost and how much you can save, such as:
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible 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 $25,000 over 20 years on your energy bills.
- The amount of sunlight your house gets: Because of Walnut's very high amount of average daily sunlight, you should be able to save a lot on your electricity bills.
- How much you spend on energy: The typical family in Walnut shells out around $750 a year on power alone, so you could be looking at that much in savings.
- Choice of solar panels: The kind of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
Solar is a profitable investment for most homeowners. You can produce your own energy instead of paying for it from a utility company and take advantage of solar tax credits and rebates, all while helping the Earth.

Solar Incentives in Walnut
To increase the number of homes and businesses that use solar power, federal, state and local governments — and even some utility companies — offer incentives to help make solar more financially viable and accessible. You can qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar panel system. You can also possibly pair the ITC with other state and city rebates and benefits. In our article on solar incentives, you can find out about the incentives you qualify for in your area.
Environmental Impact of Switching to Solar in Walnut
A lot of people want to do their part for the planet, which often is the prime motivation to install solar panels. But you may be wondering — how much exactly can you help by using solar power? One thing that can severely affect your carbon footprint is how long your commute is and how much you drive overall. If you install solar panels and have an electric car, you can greatly decrease your carbon dioxide emissions by charging your car at home. In Walnut, the average household can lower their carbon footprint by 50 pounds a year after going solar. If you want to do what you can for the environment, you'll no doubt understand that there are many advantages to adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is invaluable.

What are some of the advantages and disadvantages of installing solar panels?
The biggest advantages of solar power are that it can lower or, for some, completely cut your electricity bills, improve the value of your home and lower your carbon footprint. The biggest disadvantages are that solar panels can be expensive to install, you may not save as much if you don't use a lot of electricity and it doesn't work for all roof types and locations.
Is it worth installing solar panels on my house?
Solar panels can be a fruitful investment for many homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your electricity bills are already pretty low, solar panels might not be for you.
When is the best time of year to install solar panels?
Although summer is the most popular time people install solar panels, the best time is actually winter. You can save money since there's decreased demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.
