Best 5 Solar Companies in San Jose, CA

How To Choose the Best Solar Company in San Jose

The purchase price and effectiveness of solar panels often hinge on which company mounted them. Make your choice based on the following key factors.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar HVAC, boilers, water heaters, photovoltaic (PV) systems, and pool heaters. Contractors must complete a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, and pass written exams to secure a license. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar industry's most reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in San Jose

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power and generally have the highest quality. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can improve your solar system's efficiency. Not every solar contractor includes these optional components, so look for a provider that sells them if it's essential for you.

Most San Jose homeowners select solar systems rated for five kilowatts (kW) of electrical capacity. These systems run about $17,350 to install, considering both materials and labor. You can find more specific solar cost information in the table.

Financing Solar Energy in San Jose

There are various ways to pay for a new solar system, and the right one will lower your costs. A few of the most common options include power purchase agreements (PPAs), cash payments, loans, and leases. We recommend paying with cash or using a solar loan for the best return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar panel incentives to minimize your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases allow you to use your panels for a set monthly rate, while PPAs let you pay only for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each installer you're considering about the payment plans it offers. A team member can help you determine the best option for your financial situation.
