Benefits of Solar Energy

Solar energy offers multiple advantages that will enhance your home for years to come.

  • Better energy independence: Adding a battery storage system lets you have reliable energy during storms and grid outages.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on conventional, less environmentally-friendly sources.
  • 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.

What Solar Incentives Are Available to Union City Homeowners?

The state of California offers several solar incentives to help reduce your solar system costs. Below is a breakdown of relevant solar programs where you live.

Incentive Amount:

100% of system value; 75% of system value exemption for dual-use equipment

How To Choose the Best Solar Company in Union City

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 photovoltaic (PV) systems, pool heaters, water heaters, boilers, and HVAC. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to secure a license. Solar providers can also obtain 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 Union City

Your photovoltaic panels' type will impact how much energy you can produce. Monocrystalline panels are among the highest quality and cost the most but perform the best. Polycrystalline panels generate less, but they're a great traditional option for low budgets. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

Additional components, such as electric vehicle (EV) chargers and battery storage, will increase your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not all solar companies offer these add-ons, so look for a provider that sells them if it's important for you.

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

Solar Panel CostAverage Cost
Solar Monocrystalline$1,417.14
Solar Polycrystalline$1,105.37
Thin-Film$646.22
Solar Battery$906.97
Solar Home EV Charger$3,401.14

Financing Solar Energy in Union City

Choosing the ideal financing plan will impact your overall solar system cost and expected savings. Common payment options include cash payments, power purchase agreements, loans, and leases. Most solar experts recommend a cash payment 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. 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) lets you pay a monthly rate determined by the energy you use, like an electric bill. We generally don’t recommend these two options because you won't own the solar system and are disqualified from using solar incentives. We advise working with an installer that offers multiple financing options. Speak with each representative about what's available, and acquire more than one estimate for the best odds of staying within your budget.

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

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