Factors that Affect Solar Panel Costs in Los Altos Hills

There are a number of factors that can play into your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.

Solar Equipment

The size of the solar system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by nearly $2,730. There are a lot of different solar panel brands and the one you pick also affects the cost. Generally speaking, the brands that have better efficiency tend to also be more expensive. In addition, the type of equipment you're looking to get can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

If paying for a solar system out of pocket is difficult, solar loans are an affordable route because they cut back your upfront costs and let you pay for your system over a term of, on average, between five and seven years. However, the interest on solar loans also adds to your all-in costs, so it's vital to take that into consideration as well. You can always reduce the total you pay in interest and in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

The solar installer you select will affect your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Los Altos Hills are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. Though, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

The company that does your solar panel installation will affect the warranties and brands you have access to, and it will also have an impact on your total cost. Because selecting a company can be a challenge, we have some tips to help you, such as:

  • Solar Panel Brands: Not all solar installers carry the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you go with.
  • Reputation: Make sure your solar panel installer has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Contract: Look through the contract terms thoroughly to make sure you understand the total cost, project completion timeline incentives and warranties.
  • Installation Process: Make sure you're aligned with the company in regard to how the installation process will go and what needs to be done before your solar system is installed, such as repairing your electrical system or roof.
