Benefits of Solar Energy

Solar energy has multiple advantages that will enhance your home for years to come.

  • Better energy independence: Photovoltaic systems with energy storage operate through power outages and emergencies, and you won't have to depend on the power grid for your safety and comfort.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on fossil fuels, which release greenhouse gases that damage the environment.
  • Lowered energy bills: Solar panels allow you to generate your own energy to power your home, reducing your monthly electricity costs. You can eliminate your bills completely if you go off-grid.

How To Choose the Best Solar Company in San Jose

Choosing a company is the first step toward a well-oiled and cost-efficient solar system. Make your choice based on the following essential elements.

Licensing and Training

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

Cost of Solar Panels in San Jose

The style of solar panels you purchase determines how much electricity you can generate. Monocrystalline panels cost more but give you the best performance. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't the best for large residential installations, but they are excellent accessories for non-traditional roofs.

Additional system add-ons, such as battery storage and electric vehicle (EV) chargers, will raise your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar companies offer these additional features, so look for a contractor that sells them if it's crucial for you.

If you're a resident of San Jose and want a five-kilowatt solar energy system, you could expect to pay about $17,350 for parts and installation. See more information on specific component and panel costs in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,961
Solar Polycrystalline $1,530
Thin-Film $894
Solar Battery $1,255
Solar Home EV Charger $4,707

Financing Solar Energy in San Jose

Solar contractors offer multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar leases, power purchase agreements (PPAs), cash payments and solar loans. Most solar experts recommend paying cash or using a solar loan. Cash payments require a large up-front sum, but they save you from paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a car or home loan, you'll pay a set monthly rate with potentially $0 down. Solar leases allow you to rent 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. Look for companies that offer several payment plans to find the right fit for your budget.

The table below lists the average payback periods for different capacities of solar systems in San Jose.

You are eligible for a 26% federal tax credit for new solar energy devices until the year 2032. Municipal and state governments and utility companies might also offer discounts, rebates, and unique financing solutions that could save you more.

Solar System Capacity Estimated Payback period
1 kW 1.4 years
2 kW 2.7 years
5 kW 6.8 years
10 kW 13.7 years
