How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.

Check Licensing

Hiring a licensed solar installer is critical. This help guarantee that the work is done properly using the most up-to-date installation methods. In Missouri, it's purely up to cities and counties issue contracting licenses. However, all contractors must register with the Missouri Secretary of State.

Read Customer Reviews

Check review sites like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with companies that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Contact three to five solar companies for free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. Comparing multiple quotes helps identify the option that best fits your budget.

Ask About the Warranty

Top-notch solar installations should have strong workmanship and performance guarantees. A workmanship guarantee covers installation issues, such as poor alignment, cracks in the panels, or poor wiring. A performance warranty guarantees a minimum energy output. Comprehensive guarantees indicate that a solar company believes in its work.

Evaluate Financing and Incentives

Solar energy can help decrease your electricity costs long-term. When weighing solar panel's cost and value, be sure to weigh these considerations.

  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states offer incentives, too. The credits can lead to substantial savings for solar buyers.
  • Look into utility rebates: Some utility companies may provide additional discounts to motivate homeowners to install solar panels. Check the eligibility criteria and rebate amounts offered by your local electric provider to estimate the possible savings.
  • Compare system purchase options: Solar panels can be purchased upfront or paid for over time through a loan or lease. Verify all terms when financing, including annual percentage rate (APR), payment schedule, fees, and ownership implications.

Frequently Asked Questions About Solar in Crestwood, MO

Generally speaking, a solar photovoltaic (PV) array can be used to power any household appliance or system that uses electricity. In the simplest case, you can use a solar water heater.

With home solar panels, you can recoup the cost of the system over time, lower your property's emissions, and gain additional energy independence.

It depends on where you live and the kind of panels you plan to use. Since there's a moderate amount of snowfall in Crestwood, your best time to install solar panels is in the spring and fall.

Yes. The grid in Crestwood already uses a large share of renewable energy sources, and you may be able to sell your excess generated energy to your utility for additional cost savings.

Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can sell the solar energy you don't use to your provider. In return, they'll give you a credit on your power bill.

While solar energy is a valuable option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, a contractor might recommend other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still help the environment and could still qualify for distributed generation or other money-saving programs.

With respect to taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. For insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should consult with your accountant or insurance agent for information specific to your case.
