Benefits of Solar Energy

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

  • Lower utility costs: Producing some or all of your own energy will spend less on electricity long-term. Plus, some states offer net metering programs that make it possible for you to sell your extra energy back to the grid, generating additional credits toward your energy bill.
  • Better energy independence: Adding a battery storage system lets you have dependable energy during storms and grid outages.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on fossil fuels, which release greenhouse gases that damage the environment.

How To Choose the Best Solar Company in Walnut Creek

The purchase price and performance of solar panels often depend on the provider that mounted them. Make your choice based on the following vital factors.

Licensing and Training

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

Cost of Solar Panels in Walnut Creek

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 vehicle (EV) chargers and battery backup systems. These will increase your total installation cost, but they can enhance your solar system's efficiency. Not all solar companies offer these additional features, so look for a provider that installs them if it's crucial for you.

Generally speaking, it will cost about $17,350 for a five-kilowatt solar array in Walnut Creek. This table displays more specific costs for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,322
Solar Polycrystalline$1,031
Thin-Film$603
Solar Battery$846
Solar Home EV Charger$3,172

Financing Solar Energy in Walnut Creek

Solar installers offer multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are power purchase agreements (PPAs), solar leases, cash payments and solar loans. We suggest making a cash payment 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 cut 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 benefiting from energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) enables you to pay a monthly rate based only on the energy you use, akin to an electric bill. We usually don’t recommend these two options because you won't own the panels and are disqualified from using solar incentives. Ask each company you're considering about the payment plans it offers. A salesperson 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 Walnut Creek.

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 Walnut Creek

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

On average, Walnut Creek homeowners pay roughly $1,538 per year on electric bills. Once you pay off your solar array, you could save $1,729.84 per kilowatt you produce.

How popular is solar energy in Walnut Creek?

Yes, solar energy is readily available in Walnut Creek. A growing number of area homes are already using solar power on-site or through utility grids, and California has about 74255 jobs comprising its solar economy.

Should I anticipate a property value increase after adopting solar power?

Yes, solar panels will increase your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce 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 rainy or gloomy

Even if your property has high tree cover, you could still benefit from solar energy. Your technician will maximize your system's performance by selecting the proper site for panels, positioning them to capture the most sunlight throughout the year, installing a battery backup system, and cleaning them regularly. This way, you can store solar power and use it as necessary.

How can I determine my property's solar potential?

One common way to determine your home's solar viability is by using PVWatts. This free, powerful tool considers system size, tree cover, 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 build a full estimate with the most updated data.

How do I care for my new solar system?

To preserve your solar system's efficiency, inspections and cleanings every six months are usually sufficient. In dusty or dry seasons, your panels might need cleanings every one to two months. Your provider can recommend a maintenance schedule. Its team could also handle the cleaning for you.

Should I get quotes from multiple Walnut Creek solar companies?

Yes, we suggest obtaining free solar quotes from three to five companies. You should review each quote and compare prework scope and costs, labor fees, equipment costs, warranty details and financing options. Ensure each quote offers an itemized financial plan and includes your expected payback period.
