Factors that Affect Solar Panel Costs in Redwood City

Even though the average cost of solar panels in Redwood City is $5,867, your actual cost may differ. There are many factors that can have a major impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more electricity your household consumes, the larger your system will likely need to be. You can expect to spend about $2,730 per kilowatt in Redwood City. The kind of solar equipment you choose can increase or decrease your cost 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. However, more efficient panels could save you more in the long run on your power bills. Additionally, extra products, such as solar batteries, can bump up your total well above the Redwood City average.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are available from most installers in Redwood City, which can bring down, or in some cases totally eliminate, your upfront costs to make solar more affordable. When considering your overall cost, you should also calculate the interest you'll pay if you go with a solar loan. Also, paying more on your down payment can lower the total interest paid over time.

Solar Panel Installation Company

The solar company you go with to handle your switch to solar energy can play a role in your total costs. There are about 3 solar panel companies operating throughout Redwood City, and each can charge different amounts for labor and equipment. Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and choose a company that provides the products, warranties and services you're looking for and also is within your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Contract: Review the contract terms closely to make sure you understand the cost breakdown, project timeline rebates and warranties.
  • Reputation: Solar companies that have great reviews from their customers and that have been in business for many years likely offer high-quality solar panel installation and expertise.
  • Installation Process: Make sure you're on the same page with the installer in regard to how the installation process will go and what you need to do before your solar panels are installed, such as updating your electrical system or roof.
  • Solar Panel Brands: Each solar panel brand and kind offers varying levels of quality, durability and energy efficiency. They will come at different prices as well. The company you choose plays a role in which solar panel brands you have access to.
