Factors that Affect Solar Panel Costs in San Mateo

For many San Mateo homeowners, the decision to adopt solar energy depends on cost. However, the range of solar installation costs can be quite wide in San Mateo, with typical prices between $20,000 to $40,000. There are various factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

The size of the solar system you need for your household, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,470. The brand and kind of equipment you get 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 more savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also raise the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are available from most installers in San Mateo, which can reduce, or in some cases eliminate, your upfront costs to make solar more affordable.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs significantly.

Solar Panel Installation Company

The remaining key cost factor you should take into consideration is the installer you choose. Given the massive popularity of green energy solutions in San Mateo, you’ll have many options to choose from, but each comes at various price points for labor and equipment.Larger national companies typically have lower costs, but some local companies undercut them by offering sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

  • Installation Process: When going solar, it’s important to keep an open line of communication with your solar installer. See to it that you understand how the installation process works and the completion timeline.
  • Warranty: Each company may offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
  • Solar Panel Brands: Different companies will have various brands and kinds of panels. If you know you want a specific brand, make sure the solar installer you’re considering has it.

EcoWatch's San Mateo, CA Solar Cost FAQs

What is the average cost of installing solar panels in San Mateo?

This is a hard question to answer exactly, because the cost depends on a few different factors. Broadly speaking, it costs about $17,350 for a 5-kW system and $34,700 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have above-average energy usage. On the flip side, you can spend less if you go with a smaller solar panel system or less expensive solar panels.

What other factors should I consider other than cost when buying solar panels?

Cost is without a doubt one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.

Is switching to solar power worth it?

Solar panels can be a fruitful investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your electricity bills are already reasonably low, solar panels might not be for you.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
