How to Find the Best Solar Companies

To find the best solar company for you, first consider factors like financing options, your home’s infrastructure, and solar incentives in your area.

Financing Options

When choosing a solar provider, consider the financing plans they offer. Financial plans from solar providers typically include a loan, purchase, lease, and power purchase agreement (PPA) option. Compare the different plan options below.

Comparison of Solar Financing Options

Provider Purchase Loan Lease PPA
Provider Purchase Loan Lease PPA
Purchase option Purchase in full Purchase and finance Pay set monthly payments for installed solar panels Pay monthly payments based on energy generated by the system
Ownership Homeowner Homeowner Provider Provider
Upfront payment Full system cost Some solar loans begin as low as $0 down As low as $0 None

Home Compatibility with Solar Energy

Before selecting a solar provider, determine if your home can support a solar energy system. The main factors that affect a home’s compatibility with solar energy include household electrical demand, your roof, and where you live.

  • Household electrical demand—There’s a delicate balance between a home’s energy production and the need for solar panels. If a home doesn’t use enough monthly energy, choosing solar may be more expensive. However, if you use too much monthly energy, your home could require so many solar panels that it may not be affordable. A solar provider will look into your home’s energy consumption before installation to help you understand the savings provided by a solar system.
  • Size, age, and slope of your roofSolar panels are most efficient when facing south and on a slope between 15–40 degrees. If your roof isn’t south-facing or has a steep slope, solar can still be suitable, but it may be less efficient or more expensive. Additionally, if your roof is old or deteriorating, you should replace it before installation.
  • Location—Although climate matters when installing solar panels, your home’s location determines how effective the solar panels will be. Homes that are obstructed by buildings or tall trees could prevent you from benefitting from a solar energy system.

Solar Incentives

In addition to the 26% federal tax credit applied to solar installation, specific states and municipalities offer their own incentives to help solar energy become more affordable. Before choosing a solar provider, visit the Database of State Incentives for Renewables & Efficiency to view available incentives in your area.

Our Conclusion

The solar energy company you select is dependent on your state availability and your home’s unique energy needs. Although Vivint Solar is our best overall solar company because of its comprehensive warranties and extensive installation procedure, we recommend selecting any of the solar power companies mentioned in this article.

Frequently Asked Questions About Solar Energy

How do solar panels work?

Solar panels work by using absorbed sunlight to release the electrons stored in solar panels. The free electrons generate electricity, which flows to the solar panel’s inverter, converting it into power that your home can use. Any excess electricity your solar panels produce is stored in your solar battery or sent back to the electrical grid.

What is net metering?

When more energy than needed is generated by your solar panels, the excess energy is fed to the electrical grid. When you “give” energy to the electrical grid, your utility company rewards you with credit on your monthly electric bill, reducing its overall cost.

How often should solar panels be cleaned?

Solar panels should be cleaned twice a year with soap and water.

Do solar panels generate electricity at night?

No. Solar panels can’t produce electricity at night, but you can access solar energy during that time if you incorporate a solar battery into your system.

How does solar energy benefit the environment?

Solar power is a renewable resource and prevents the use of fossil fuels to generate electricity, reducing the amount of pollution in the environment.
