Factors that Affect Solar Panel Costs in Walnut Creek

The cost of installing a solar system in Walnut Creek can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The largest one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power generation need better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,470.The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get 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 over time on your energy bills. Additionally, add-on products, like solar batteries, can bring your total well above the Walnut Creek average.

Solar Financing Terms

Many homeowners find the average cost of solar in Walnut Creek to be prohibitively steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area provides access to financing options. Solar loans greatly decrease upfront costs in most cases, but they also result in a higher cost over time because of interest.However, the interest on solar loans also adds to your overall costs, so it’s important to consider that as well. You can always bring down 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 panel installation company you select will impact your total cost to adopt solar energy. Different companies will bill different amounts for the equipment and labor.Larger national companies typically have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

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

  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. Although there are many options for which type of solar panel you can get, not every company will have the exact one you may want or need, so be sure to ask for their list of options before making your decision.
  • Reputation: Your solar installer should have a sound reputation as a company and have proven expertise in the field. A couple of ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from past customers.
  • Contract: It’s important to read through your solar installer’s contract thoroughly to understand what services they will provide, what the warranty covers and what expectations you should have about the installation process.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar system running for a long time and save you money on repairs and maintenance.
