Factors that Affect Solar Panel Costs in California
There are many criteria that can affect your installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.
Solar Equipment
When it comes to estimating the cost of a solar system in California, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home’s energy consumption, which you can determine by looking at past electricity bills. Your overall cost can increase by around $3,550 for each additional kilowatt you need.The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in California to be prohibitively expensive, even if the investment pays off over time. Thankfully, nearly every solar company in the area provides access to financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in higher prices over time because of interest.However, the interest on solar loans also adds to your total costs, so it’s vital to consider that as well. You can always bring down the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
A final factor to consider when trying to evaluate the cost of solar for your home or business in California is the company you hire to install your solar system. Similar to choosing a company to install new cabinets, for instance, there are plenty of solar installers that provide a range of services at different costs.Larger national companies generally have lower costs, but some local companies keep up with 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 a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you decide on the right company for you, here are some tips to keep in mind:
- Warranty: A high-quality company stands out from other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Solar Panel Brands: Not all solar companies have the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
- Reputation: Make sure your solar system installer has a good reputation by verifying it has certifications and licenses, checking how long it's been in business and reading reviews by past customers and solar experts like EcoWatch.
- Installation Process: Get detailed information from your solar installer about the installation process and what to expect, such as when the site survey will be done and how long it will take.
