How To Choose the Best Solar Company in Castro Valley

The purchase price and efficiency of solar panels often depend on the solar company that installed them. Consider all of these criteria in your service provider search.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar photovoltaic (PV) systems, pool heaters, boilers, HVAC, 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 secure a license. Check a company's website for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar sector's most respected trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Castro Valley

The type of solar panels you purchase dictates how much power you can produce. Monocrystalline panels and high-quality and give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't the best for large residential installations, but they are excellent accessories for non-traditional roofs.

If you need to charge an electric car or use your solar power in dark weather, you can pay extra for accessories. By choosing the right components, you can make your system more efficient and convenient to use. Not all solar contractors include these extras, so look for a company that installs them if it's important for you.

If you're a resident of Castro Valley and are considering getting 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 solar panel costs in the table.

Financing Solar Energy in Castro Valley

There are various ways to pay for a solar energy system, and the right one will reduce your expenses. A few of the most common options include power purchase agreements (PPAs), cash payments, loans, and leases. We advise paying with cash or securing 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 own your system and can apply for solar panel incentives to reduce 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 monthly installments while still enjoying energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases let you use your panels for a set monthly rate, while PPAs let you pay only for the energy you use, similar to 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 business you're vetting about the payment plans it offers. A consultant can help you determine the optimal option for your financial situation.

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

The IRS allows you to claim a 26% federal tax credit for solar panels on total system costs, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own rebates, financing programs, and incentives that could save you more money.
