  • Customer reviews and feedback: Most Costa Mesa solar providers have both positive and critical reviews. However, a good review ratio shows a company's trustworthiness and responsiveness to issues.
  • Educational programs and business model: Solar technicians must be good teachers. They should utilize their years of experience answer your questions on how to maintain your system and optimize its performance.
  • Warranty and service offerings: Solar providers should stand behind their systems and services with warranties. We evaluated how each installer responds to issues and warranty claims, focusing on promptness and customer happiness.

Benefits of Solar Energy

Solar energy provides multiple perks. Let's look at a few of them.

  • Reduced carbon footprint: Solar is the universe's most abundant clean energy source, meaning you can lower or beat your home's dependence on "traditional" sources.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, reducing your monthly electricity costs. You can eliminate your bills completely if you go off-grid. Plus, a significant amount of states have adopted net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Better energy independence: Adding a battery backup or storage system lets you have trustworthy energy during grid outages and storms.

What Solar Incentives Are Available to Costa Mesa Homeowners?

California homeowners who upgrade to solar could qualify for special financing, tax credits, rebates and reimbursements. Here are just a few of the local incentive offerings.

Incentive Amount:

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

How To Choose the Best Solar Company in Costa Mesa

Choosing a company is the first step toward a well-oiled and cost-efficient solar array. Consider each of these factors in your business search.

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 complete a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. You should also visit a company's website to learn about its private credentials. Two of the most respected are the PV Installation Professional and Solar Heating Installer certificates, granted by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Costa Mesa

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 provide a lower price point but produce less power. 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.

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 panel array more effective and convenient to use. Not all solar contractors offer these additional features, so look for a provider that installs them if it's essential for you.

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

Solar Panel CostAverage Cost
Solar Monocrystalline$1,235.00
Solar Polycrystalline$963.30
Thin-Film$563.16
Solar Battery$790.40
Solar Home EV Charger$2,964.00

Financing Solar Energy in Costa Mesa

There are a plethora of ways to pay for a new solar system, and the right one will reduce your expenses. A few of the most common options include power purchase agreements (PPAs), leases, cash payments, and loans. We recommend making a cash payment 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 have full ownership of your system and can apply for solar panel incentives to reduce your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in 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) permits you to pay a monthly rate based only on the energy you use, as with an electric bill. We generally don’t recommend these two choices because you won't own the system and cannot use solar incentives. Ask each installer you're evaluating about the payment options it offers. A team member can help you determine the best option for your financial situation.

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

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