The Cost and Benefits of Solar in Westmont
For many homeowners, the decision to invest in solar energy boils down to the cost. There are several factors you should consider when trying to determine costs and your potential savings, including:
- The amount of 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 leave you with lower savings on power bills than a roof that gets a lot of sunlight.
- Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your energy bills, which can result in an average of $28,000 of savings over 20 years.
- Choice of solar panels: The type of solar panels you need will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also lead to more savings over the lifetime of your system. If you don't need to maximize efficiency, you can opt for a higher number of more affordable panels.
- How much electricity your home consumes: Homes that use lots of power each month may require more solar panels and, as a result, be more expensive, but will also enjoy more savings over time.
Thanks to solar panels now being cheaper than ever as well as various solar incentives, they are a solid investment for most homeowners.

Environmental Impact of Switching to Solar in Westmont
One of the most compelling reasons to switch to solar energy is to reduce your reliance on nonrenewable energy sources like burning fossil fuels, which are hazardous for the environment. But you may be curious — how much exactly can you help the environment by using solar power? How much energy you use is a significant factor to think about. The more electricity your household consumes, the bigger your impact when you switch to solar energy. After you go solar, your carbon emissions can be cut by about 50 pounds each year. As you can see, trading traditional energy for solar has so many other perks beyond saving money. One of the main ones is that you can help save the Earth too.

EcoWatch's Westmont, CA Solar Company Rankings FAQs
What is the most reputable solar panel installer in Westmont?
The highest-rated local solar company in Westmont is Renewable USA, with a rating of 5.00 stars.
What are a few of the main advantages and disadvantages of adopting solar power?
The advantages of solar power are that it can reduce or, in some cases, entirely erase your electricity bills, improve your home's value and lower your carbon footprint. The disadvantages are that solar panels can be pricey to install, you may not save a lot if you don't use a lot of electricity and it doesn't work for all roof types and locations.
Is it worth putting solar panels on my house?
Solar panels call for a large upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a variety of factors like the cost of electricity near you and how much direct sunlight your roof gets.
How long do solar panels last?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them once you've had them for that long or you can continue to use them at a lower efficiency after that time.
