Benefits of Solar Energy

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

  • Reduced carbon footprint: Utilizing solar is a surefire way to lower your carbon footprint and home fossil fuel dependency.
  • Better energy independence: Solar panel systems with battery storage systems operate through blackouts and emergencies, and you won't have to depend on the grid for your safety and comfort.
  • Lowered energy bills: You can skip the added cost of grid-tied power by creating some electricity right where you use it. Plus, many states provide net metering which can allow you to sell your unused energy back for credits on your bill.

How To Choose the Best Solar Company in Antioch

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 water heaters, pool heaters, HVAC, boilers, and photovoltaic (PV) systems. Contractors must complete a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. Solar providers can also earn certificates from trade groups and standards organizations. The most respected ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Antioch

Your solar modules' model will impact how much power you can produce. Monocrystalline panels are among the highest quality and perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

If you need 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 productive and convenient to use. Not every solar provider provides these additional features, so look for a provider that installs them if it's a priority for you.

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

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 Antioch

There are numerous 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), loans, leases, and cash payments. Though it involves a large up-front payment, cash is the most affordable choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the second most effective option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) permits you to pay a monthly rate determined by the energy you use, akin to an electric bill. We usually don’t recommend these two choices because you won't own the solar system and are disqualified from using solar incentives. Ask each business you're evaluating about the payment options it offers. A consultant can help you determine the best option for your pocketbook.

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

You are eligible for a 26% federal solar tax credit for new solar energy equipment until the year 2032. Municipal and state governments and utility companies might also offer rebates, discounts, and dedicated financing plans that could save you more.

Frequently Asked Questions About Solar in Antioch

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

Most Antioch homeowners spend about $1,538 on energy each year. Your costs could drop by $1,729.84 for each kilowatt you generate after you pay off a solar array.

How prevalent is solar energy in Antioch?

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

Will a solar PV system increase my Antioch home value?

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 rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

How long will a common solar system last?

Modern solar panels are built to last. The average panel provides 25 years of reliable power. Cheaper panels tend to last shorter than top-tier models.

Is solar installation a quick job?

Your solar job's duration will depend on its complexity and size, as well as Antioch's permit and inspection procedures. It could take several weeks to two months on average.

What's the average solar system size in Antioch?

The average Antioch solar system size is 3.0 kilowatts (kW). However, your final system size depends on your home's energy needs. Your roof size, panel model, and surrounding shading could also impact your final result. A professional solar contractor will consider these factors and determine the right system size for your home.

How are traditional solar loans and PPAs different?

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 continue the contract or buy the system.

You might think about 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 cost-saving solar incentives. Many solar experts don’t recommend PPAs. Our guide covers other financing options above.

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

Yes, we advise requesting free solar quotes from three or more companies. You should thoroughly read each quote and compare equipment costs, warranty details, prework scope and costs, labor fees and financing options. Ensure each quote provides an itemized financial plan and includes your anticipated payback period.
