Top 10 Best Solar Energy Companies of 2022 | ConsumerAffairs (2023)

Going solar is much easier than it used to be. Once you determine your energy needs and compare solar energy companies, make sure your roof can handle having solar panels installed. You should understand solar incentives and consider the available financing options.

It’s smart to get quotes from multiple companies — this ensures you get the best deal on all your solar equipment components. Most reputable companies offer free consultations. If you hire an installer, its employees do all the heavy lifting and help you complete permitting paperwork. Finally, connect to the grid to officially go solar.

The first step in going solar is determining how much energy your home uses. The average U.S. household uses approximately 890 kWh of electricity per month, according to the U.S. Energy Information Administration. Considering each solar panel generates between 1 and 1.5 kWh of power each day, the average American home would need between 20 and 30 panels to run entirely on solar.

Generally, the more panels on a home or business, the more energy the system can create. The amount of electricity your panels generate varies by location and available sunlight. The efficiency of your solar panels and how much power you require in your home or business determines the number of solar panels you need.

Find out if your state offers solar incentives, such as government subsidies or rebate programs designed to encourage more residential solar energy systems. Solar investment tax credits also make the economic benefits of solar energy accessible to more people.
Solar modules and installation costs have gone down since the commercial solar industry started. Still, going solar isn't affordable for the average homeowner without a little help. To offset the high upfront price of going solar, many solar companies offer financing loans or power purchase agreement (PPA) programs, where the homeowner only pays for electric output for a set period, while a third-party developer handles installation, financing and installation and owns the system.

Solar loans have terms and conditions similar to most other home improvement loans. Some states and nongovernmental organizations offer subsidized solar energy loans with reduced interest rates.

Solar lease companies let you use solar panel equipment for a fee. Homeowners who choose to lease solar panels instead of purchasing them don't receive the same tax credits, rebates or other incentives offered by the federal government and local utility companies.

Select a handful of companies in your area that provide residential solar power options, then request quotes so you can compare pricing. Many solar companies provide free on-site consultations, where they can examine your property and go over your options and pricing.

Most solar energy companies want to see an annual statement of your electric bill to estimate costs, so it’s smart to have that information ready when you’re requesting bids. All solar contractors will provide you with a quote that states how much you will save over the long term.


To narrow down your solar power options, check each company’s licenses and insurance policies. You should request quotes from at least three of your top picks. As you’re requesting a quote, ask the following questions:

  • How many solar installations have you completed? Can you provide references?
  • What types of solar panels do you use?
  • What solar loans or financing programs do you offer?
  • What rebates and incentives do I qualify for?
  • How many solar panels will I need based on my monthly energy consumption?
  • How much do you project for savings for my household?
  • How long will the process take?
  • Will you take care of city permitting and state requirements?
  • Is there a system performance guarantee?
  • What does your warranty cover, and for how long?
The best solar brands maximize the amount of energy you can generate in the minimum amount of space. You should evaluate solar panels and other equipment options on three primary parameters: electricity production, durability and quality. Remember to ask about the warranty for all solar equipment components.
  • Solar panels: As you compare solar energy options, remember that higher efficiency is always better. Currently, three types of panels are available on the solar market — monocrystalline, polycrystalline and thin-film amorphous.

    Residential solar energy systems most commonly incorporate monocrystalline and polycrystalline solar panels. Thin-film amorphous solar panels are cheaper but also less efficient, which makes them more ideal for commercial applications where space isn’t a concern.

    • Degradation rate: Pay attention to the degradation rate and temperature coefficient to find quality solar panels. The degradation rate refers to how much the output declines each year — the average degradation rate for solar panels is about 0.8%, so anything less than that is more durable than average.
    • Temperature coefficient: The temperature coefficient refers to how much panels decrease in efficiency each degree above 25 degrees Celsius (PV modules are tested at 25 C, so 25 C is the solar industry’s universal reference point). Look for PV modules with a temperature coefficient between -0.3% and -0.5%.
  • Power inverter: An inverter converts DC electricity into AC electricity, which is what powers your home. After panels, your inverter is the most critical part of your solar energy system. To select the best inverter for you, consider how many watts you need and the power rating. The most common kinds of inverters are string inverters, central inverters and microinverters.
  • Storage batteries: Solar storage batteries provide continuous power to your home, even when the sun isn’t shining. These batteries come in handy whether you're on or off the grid. The best solar batteries can store large amounts of electricity and withstand multiple discharge-recharge cycles.
  • Charge controllers: Charge controllers regulate current and voltage to prevent batteries from overcharging. Solar charge controllers can be either PWM (pulse width modulation) or MPPT (maximum power point tracking). Generally, MPPT controllers are more efficient but more expensive.
  • Monitoring equipment: Monitoring equipment connects to the inverter and lets you know how efficiently your panels are generating electricity. Most solar energy companies use proprietary software to monitor solar arrays.
Once you have an idea of the solar equipment you want, start thinking about whether you want to work with a national or local solar company. There are pros and cons to both — national companies sometimes have better warranties, but local companies are more familiar with your state’s incentives and permitting requirements. According to the National Renewable Energy Laboratory (NREL), local solar installers cost an average of 10% less than national residential solar installers.

Before selecting a local solar installation company, check out the company's reviews from customers and ask for references from homeowners who've recently completed a similar system installation. Find out if the solar company employs in-house installers or uses contractors. You should also consider whether the company offers in-house financing and if it offers warranties for parts or equipment.

Finally, consider hiring a competent electrical engineer to review the installation. This will ensure a smooth installation with few problems during the process and in the future.

There’s some paperwork to complete before solar panels can be installed. Homeowners must apply for proper permits with their state or local government. You might have to comply with building codes, depending on where you live. Without the correct paperwork, you risk hefty fines.

You then need to make arrangements with your local utility company to outline a net-metering agreement, a contract that details the responsibilities for you and the utility company and covers information like electric rates and compensation for excess energy fed into the grid. Your utility company may also require justification for the size of your system, particularly if it produces more power than you typically use.

A final inspection is required to ensure the system meets safety regulations before you can connect to your local utility grid. A grid system provides reliable, economical electricity. Solar panels can be directly connected to a power inverter and then connected to a home grid, or they can be connected to the inverter through the battery and then to the home grid. It’s not wise to install the panels yourself, though; instead, hire a qualified professional with certification who works with high-quality solar panels.
