Benefits of Solar Energy

Solar energy comes with multiple benefits. Here are some highlights.

  • Reduced carbon footprint: Solar is the universe's most abundant clean energy source, meaning you can reduce or eliminate your home's dependence on "traditional" sources.
  • Better energy independence: Solar panel systems with battery backups and storage systems function through power outages and emergencies, and you won't have to rely on the power grid for your safety and comfort.
  • Lowered energy bills: You can dodge the added cost of grid-tied power by generating some electricity at home. Plus, many states provide net metering which can allow you to sell your unused energy back to credit part of your bill.

How To Choose the Best Solar Company in San Francisco

The price and efficacy of solar panels often rely on which company mounted them. Here are some essential aspects to consider while searching for a solar company.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar HVAC, boilers, photovoltaic (PV) systems, pool heaters, and water heaters. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. You should also visit a company's website to learn about its private credentials. Two of the most recognized are the Solar Heating Installer and PV Installation Professional certificates, granted by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in San Francisco

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 electric car (EV) chargers and battery backup systems. These will increase your total installation cost, but they can improve your solar system's performance. Not every solar contractor offers these additional features, so look for a provider that installs them if it's essential for you.

You can plan to spend about $17,350 on average for a five-kilowatt solar energy system in San Francisco. Use the table in this section to get an idea of what amount San Francisco solar companies might quote for your specific solar system's price.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,359
Solar Polycrystalline$1,060
Thin-Film$620
Solar Battery$869
Solar Home EV Charger$3,261

Financing Solar Energy in San Francisco

Choosing the best financing plan will affect your overall solar system cost and possible savings. Common payment options include power purchase agreements, cash payments, leases, and loans. We recommend making a cash payment or using a solar loan for the highest 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 reduce your total costs. Solar loans are another solid 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 spend more in total due to accruing interest. Solar leases allow you to rent your panels for a set monthly rate, while PPAs let you pay just for the energy you use, akin 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. Look for contractors that offer multiple payment plans to find the right fit for your financial needs.

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

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own rebates and financing plans that could reduce your total cost even more.

Frequently Asked Questions About Solar in San Francisco

How much energy and money could I save per year by switching to solar?

Most San Francisco homeowners spend about $1,395 on energy each year. Your costs could drop by $1,612.65 for each kilowatt you generate after you pay off a solar array.

How popular is solar energy in San Francisco?

Yes, solar energy is readily available in San Francisco. A growing number of local homes already use solar power on-site or through utility grids, and California has about 74255 jobs comprising its solar economy.

Should I anticipate a boost in my property value after installing solar panels?

Yes, solar energy systems will boost your property value. According to the National Renewable Energy Laboratory, for every dollar you save on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a gloomy or dark

Even if you reside in one of San Francisco's few dark areas, you could still use solar energy. Your technician will optimize your system's performance by selecting the proper site for panels, installing a battery backup system, positioning them to capture the most sunlight throughout the year, and cleaning them regularly. This way, you can store solar power and utilize it as necessary.

What is a San Francisco solar panel's average lifespan?

Modern solar installations are designed for durability. The average panel provides 25 years of reliable power. Budget panels tend to last shorter than higher-quality models.

What size should my new San Francisco solar system be?

The average San Francisco solar system size is 3.1 kilowatts (kW). However, your final system size depends on your household's energy needs. Your roof size, panel model, and surrounding shading could also impact your final result. A professional solar company will consider these factors and determine the right system size for your home.

What's the difference between a PPA and traditional financing?

The main differences between a PPA and traditional financing are that you pay a fluctuating monthly rate based on your energy usage and don't own your system. Your solar company installs and maintains the panels, and you pay for the generated electricity for 10–25 years. Afterward, you can extend the agreement or purchase the system outright.

You might consider a PPA if you don’t want to be responsible for maintenance and don’t want to invest in a system, but keep in mind you won’t be paying toward ownership or be able to access any solar financial incentives. Many solar experts don’t recommend PPAs. Our guide covers other payment options above.
