Benefits of Solar Energy

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

  • Reduced carbon footprint: The sun is the universe's most abundant clean energy source, meaning you can lower or beat your home's dependence on fossil fuels.
  • Better energy independence: Solar panels can keep your home functioning through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with optional battery storage.
  • Lowered energy bills: You can dodge the added cost of grid-tied power by producing some electricity at home.

How To Choose the Best Solar Company in Sunnyvale

Choosing a company is the first step toward an effective and cost-efficient solar system. Make your choice based on the following crucial aspects.

Licensing and Training

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

Cost of Solar Panels in Sunnyvale

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. 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 want to charge an electric vehicle (EV) or use your solar power in cloudy weather, you can pay extra for accessories. By choosing the right components, you can make your panel array more effective and user-friendly. Not all solar contractors offer these additional features, so look for a contractor that installs them if it's important for you.

You can expect to pay about $17,350 on average for a five-kilowatt solar energy system in Sunnyvale. Check the table in this section to get an idea of how much Sunnyvale solar companies might quote for your specific system.

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 Sunnyvale

Choosing the best financing option will influence your overall solar system cost and potential savings. Common payment options include loans, cash payments, power purchase agreements, and leases. Most solar experts recommend paying cash or using a solar loan. Cash payments demand 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 as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) allows you to pay a monthly rate determined by the energy you use, similar to an electric bill. We usually don’t recommend these two choices because you won't own the panels and are disqualified from using solar incentives. We recommend working with a company that offers multiple financing options. Talk to each consultant about what's available, and obtain more than one estimate for the best odds of keeping within your financial plan.

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

A 26% federal tax credit applies to new home solar systems purchased through 2032. Further incentives may be available through city and state governments, usually in the form of rebates and special financing programs.

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

Frequently Asked Questions About Solar in Sunnyvale

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

On average, Sunnyvale homeowners shell out approximately $1,538 per year for energy. Once you repay your solar array, you could save $1,596.28 per kilowatt you produce.

Is solar energy common in Sunnyvale?

Yes, solar energy is becoming increasingly popular in Sunnyvale. Some homes already use solar power on-site or through utility grids, and they're fortified by a state solar economy with 74255 job opportunities and counting.

Will a solar PV system boost my Sunnyvale home price?

Yes, a solar PV system will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How can I check my home's solar feasibility?

One common way to determine your home's solar viability is by using PVWatts. This free, powerful tool considers tree cover, system size, panel efficiency, and local weather and topography to determine how much electricity your array could generate. However, it's not a substitute for consulting with a solar energy professional, who can create a full estimate with the most updated data.

How long will a typical solar system last?

Today's solar systems are impressively durable, lasting up to 25 years. Monocrystalline panels and other top-tier models tend to work longer than "budget-friendly" models.

How do I care for my new solar system?

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

How does "net metering" work, and do I need to participate?

Net metering is a method that credits solar homeowners for any excess electricity they generate and feed back to the grid.

Some states or power companies mandate you to join net metering when installing your solar system, while others give you a choice. Either way, once you participate, you'll get a check or bill credit for your excess generation at a wholesale or retail rate.

How many estimates should I get before making a final solar company decision?

It's prudent to obtain three or more estimates before committing to a single solar installer. This allows you to evaluate product quality, warranty options, customer feedback, and pricing. It also lets you gauge a contractor's reliability, knowledge and responsiveness, all of which are "green flags".
