Benefits of Solar Energy

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

  • Better energy independence: Adding a solar battery storage system lets you have reliable energy during storms and grid outages.
  • Lowered energy bills: Solar panels allow you to generate your own energy to power your home, decreasing your regular electricity costs. You can eliminate your bills completely if you go off-grid. Plus, a significant amount of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • 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 Glendora

The more thorough your provider search is, the better your solar panels will ultimately work. Consider all of these factors in your service provider search.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar pool heaters, boilers, HVAC, photovoltaic (PV) systems, and water heaters. Contractors must complete a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, and pass written exams to secure a license. Solar installers can also earn certificates from standards organizations and trade groups. 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 Glendora

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options 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.

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

If you're a resident of Glendora and are considering getting a five-kilowatt solar energy system, you could expect to pay about $17,350 for materials and labor. Find more information on specific component and solar panel costs in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,194
Solar Polycrystalline$931
Thin-Film$544
Solar Battery$764
Solar Home EV Charger$2,865

Financing Solar Energy in Glendora

There are various ways to pay for a new solar system, and the right one will minimize your overhead. A few of the most common options include cash payments, power purchase agreements (PPAs), loans, and leases. We advise paying with cash or securing a solar loan for the highest 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 reduce your total costs. Solar loans are another solid 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) lets you pay a monthly rate based only on the energy you use, as with an electric bill. We generally don’t recommend these two options because you won't own the system and cannot use solar incentives. Look for companies that offer multiple payment plans to find the right fit for your wallet.

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

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, utilities and local governments may have their own rebates and financing plans that could reduce your total cost even more.

Solar System CapacityEstimated Payback period
1 kW1.4 years
2 kW2.7 years
5 kW6.8 years
10 kW13.7 years
