Factors that Affect Solar Panel Costs in Westmont
There are several criteria that can play into your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that influences the overall cost of going solar. For that reason, it's crucial to accurately assess the size of the solar energy system needed for your home by figuring out your typical energy use. The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, higher efficiency could save you more in the long run on your energy bills. In addition, add-on products, such as solar batteries, can bring your total well above the Westmont average.
Solar Financing Terms
If paying for solar panels in cash is too expensive, solar loans are a popular option because they lower your upfront costs and allow you to pay for your system over five to seven years on average. It's wise to factor the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay off the loan.
Solar Panel Installation Company
The solar installation company you select will affect your total cost to make the switch to solar . Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Westmont have more knowledge about local solar incentives and can help you make good use of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could end up saving you more money in the long run.

How to Save on Solar Panels
The solar panel company you opt for will impact not only your total costs, but also the kinds of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are several important things you should take into account, including:
- Contract: Though reading through a contract can take a lot of time, it's important to do it carefully so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
- Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should secure and how long the project will take.
- Warranty: A quality company rises above other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Solar Panel Brands: Different companies carry different brands and kinds of panels. If you want a specific brand, make sure the solar company you're considering has it.

EcoWatch's Westmont, CA Solar Cost FAQs
What is the average cost of installing solar panels in Westmont?
The average cost of solar panels in Westmont is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the real cost will depend on certain factors such as the type of solar panels you want, what size system you need and how much energy you use.
Is cost the most important thing to consider when buying solar panels?
Cost is without a doubt one of the most important things to bear in mind when buying solar panels, but other important factors include efficiency, durability, and quality.
Is making the switch to solar worth it?
Solar panels can be a beneficial investment for most homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your energy bills are already fairly low, solar panels might not be for you.
How often do you have to replace solar panels?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can replace them after having them for that long or you can continue to use them at a lower efficiency.
