Benefits of Solar Energy

Solar energy offers multiple advantages. Let's look at a few of them.

  • Reduced carbon footprint: Using solar is a surefire way to lower your carbon footprint and home fossil fuel dependency.
  • Smaller power bills: Generating some or all of your own power will save you money on your electric bills long-term. Plus, some states provide net metering programs that make it possible for you to sell your surplus energy back to the grid, generating extra credits toward your energy bill.
  • Better energy independence: Photovoltaic solar panel systems with energy storage systems work through blackouts and emergencies, and you won't have to depend on the electrical grid for your safety and comfort.

How To Choose the Best Solar Company in El Cajon

The cost and performance of solar panels often rely on the provider that mounted them. Consider all of these aspects in your contractor search.

Licensing and Training

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

Your photovoltaic panels' style will impact how much electricity you can generate. Monocrystalline panels are among the highest quality and cost the most but perform the best. 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.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can improve your solar system's efficiency. Not every solar contractor provides these additional features, so look for a contractor that installs them if it's a priority for you.

Generally speaking, it costs about $17,350 for a five-kilowatt solar array in El Cajon. This table displays more specific pricing information for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,226
Solar Polycrystalline$956
Thin-Film$559
Solar Battery$784
Solar Home EV Charger$2,942

Financing Solar Energy in El Cajon

Solar installers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are power purchase agreements (PPAs), solar loans, solar 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 next best option. As with a car or home loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for money-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to rent your panels for a fixed monthly rate, while PPAs let you pay just for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each business you're considering about the financing options it offers. A consultant can help you determine the optimal option for your budget.

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

The IRS allows you to claim a 26% federal solar tax credit on your new solar panels, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own incentives, rebates, and financing programs that could save you more money.

How can I assess my property's solar viability?

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

What care do my solar panels need, and how often do they need it?

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

How can I boost my solar panels' performance?

  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

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 return to the grid.

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