Benefits of Solar Energy

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

  • Lowered energy bills: With solar energy systems, you produce power without paying the tacked-on costs of grid-connected power. You can eliminate your bills completely if you go off-grid. Plus, a significant number of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Better energy independence: Photovoltaic solar panel systems with energy storage systems operate through power outages and emergencies, and you won't have to rely on the electrical grid for your safety and well-being.
  • Reduced carbon footprint: Solar is the universe's most abundant clean energy source, meaning you can minimize or conquer your home's dependence on "traditional" sources.

How To Choose the Best Solar Company in Berkeley

The purchase price and efficacy of solar panels often depend on which company mounted them. Here are some key items to keep in mind while shopping 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 water heaters, photovoltaic (PV) systems, HVAC, boilers, and pool heaters. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to secure a license. You should also visit a company's website to learn about its private credentials. Two of the most respected are the PV Installation Professional and Solar Heating Installer certificates, backed 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 Berkeley

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 provide a lower price point but produce less power. 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.

If you need to charge an electric car or use your solar power in inclement weather, you can pay extra for accessories. By choosing the right components, you can make your panel array more effective and convenient to use. Not every solar contractor offers these add-ons, so look for a provider that installs them if it's a priority for you.

If you're a resident of Berkeley and want a five-kilowatt solar energy system, you could plan to spend about $17,350 for materials and labor. See more information on specific component and solar panel costs in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,417
Solar Polycrystalline$1,105
Thin-Film$646
Solar Battery$907
Solar Home EV Charger$3,401

Financing Solar Energy in Berkeley

There are numerous ways to pay for a solar energy system, and the right one will help you decrease overhead. A few of the most common options include loans, cash payments, power purchase agreements (PPAs), and leases. Most solar experts recommend paying cash or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Much like a home or car loan, you'll pay a set monthly rate with potentially $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a PPA lets you pay a variable rate based on only the energy you use. We generally advise against these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in certain circumstances. Look for companies that offer several 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 Berkeley.

A 26% federal solar tax credit applies to new residential solar equipment purchased through 2032. Extra incentives may be available through local governments, usually in the form of rebates and special financing programs.

What if I live in a heavily-wooded or dark

A solar system could still work well in bad weather. Your contractor will position your panels to capture the most sunlight possible. They might also recommend a back-up power source to keep your system performing at its best.

How do I care for my new solar system?

Solar panels don't require much upkeep to keep working well. All you'll need to do is inspect and clean the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to assist in your system's care.

How long does it take to pay back a solar loan in Berkeley?

  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

What is "net metering," and how does it work?

Most utilities and states provide net metering programs, and some mandate homeowners to join. Once you register, you can obtain a bill credit or check for any surplus electricity you produce and send to the grid. Generally, power companies reimburse solar homeowners at an "avoided-cost" or wholesale rate.
