How To Choose the Best Solar Company in El Cajon

The cost and effectiveness of solar panels often hinge on which company mounted them. Make your choice based on the following important considerations.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar pool heaters, photovoltaic (PV) systems, boilers, HVAC, and water heaters. 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. Check a company's website for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar sector's most respected trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in El Cajon

The type of solar panels you select determines how much electricity you can produce. Monocrystalline panels cost more but give you the best performance. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't the best for large residential installations, but they are excellent accessories for non-traditional roofs.

If you'd like to charge an electric car or use your solar power in inclement weather, you can pay extra for accessories. By selecting the right components, you can make your system more effective and convenient to use. Not every solar company includes these add-ons, so look for a provider that sells them if it's important for you.

Generally speaking, it costs about $17,350 for a five-kilowatt solar array in El Cajon. This table lists more specific prices 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 providers use 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 loans, solar leases and cash payments. Though it involves a large up-front payment, cash is the most cost-effective choice because it qualifies you for solar incentives and doesn't accrue interest. 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 money-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases let you use your panels for a set 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 do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We advise working with a provider that offers multiple financing options. Speak with each salesperson about what's available, and secure more than one estimate for the best odds of staying within your spending limits.

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

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

Frequently Asked Questions About Solar in El Cajon

How much money could I save by going solar in El Cajon?

Most El Cajon homeowners spend about $1,659 on energy each year. Your costs could drop by $1,637.07 for each kilowatt you generate after you pay off a solar array.

Is solar energy widely available in El Cajon?

Yes, solar energy is reaching new heights in El Cajon. Some homes already generate solar power on-site or through utility grids, and they're fortified by a state solar economy with 74255 workers and counting.

Should I expect a property value increase after going solar?

Yes, solar energy systems will boost your property value. According to the National Renewable Energy Laboratory, 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.

How can I assess my site's solar viability?

One common way to calculate your home's solar viability is by using PVWatts. This free, powerful tool considers local weather and topography, panel efficiency, system size, and tree cover to determine how much energy 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 maintenance do my solar panels need, and how frequently do they need it?

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

What is the average payback period for El Cajon solar panels?

Most El Cajon homeowners pay back a solar loan in 7.4 years. You can shorten the payback period by paying off extra loan principal each month.

How can I maximize my solar system's performance?

To enhance your solar system's performance, you can use the following steps:
  • optimize the panels' position with your solar installer
  • 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?

Most states and utilities offer net metering programs, and some mandate homeowners to join. Once you sign up, you can receive a check or bill credit for any surplus electricity you generate and send to the grid. Generally, power companies reimburse solar homeowners at a wholesale or "avoided-cost" rate.
