How To Choose a Solar Company

Putting solar panels on your roof could cut your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

Hiring a licensed solar installer is critical. This helps ensure that the work is done properly using current best installation practices. The installation team for a solar photovoltaic (PV) system in Maryland must include a Home Improvement Commission-licensed contractor and a master electrician with at least seven years' experience. The contractor installs the panels, while the master electrician handles permit business and connects the system to the grid. If you're installing a solar water heater, your contracting team must include a master plumber for permits and utility connections.

Read Customer Reviews

Look at review platforms such as the Better Business Bureau (BBB), Google Reviews, and TrustPilot to find out what previous customers are saying about local solar companies. Reviews can give you an idea of a company’s dependability and customer service. Be wary of companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

To find a solar installer that works with your budget, ask for free, detailed quotes from at least three providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the most cost-effective option.

Ask About the Warranty

Quality solar installations should come with comprehensive workmanship and performance guarantees. The workmanship guarantee covers any installation issues such as poor wiring, cracks in the panels, or poor alignment. The performance guarantee ensures a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar energy can help you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.

  • Compare system purchase options: Solar panels may be paid for upfront or financed over time through a lease or loan. Confirm all terms when financing, such as annual percentage rate (APR), fees, payment schedule, and ownership implications.
  • Look into utility rebates: Local power companies may have extra financial benefits to motivate homeowners to install solar panels. Review the qualification rules and rebate amounts with your local provider to figure out your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to the full system cost is available through 2032. Many states also have incentives. These credits offer substantial savings for solar buyers.

Frequently Asked Questions About Solar in Gaithersburg, MD

A solar photovoltaic (PV) system can generate power to run any electric appliance or system in your home. A more specific example is installing a solar heating system for your water.

With home solar panels, you can recoup the cost of the system over time, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.

Yes, you can use home solar energy alongside conventional power sources. In most parts of the country, solar panels are designed to supplement your existing energy sources, which means you can reap the environmental benefits and savings that come from using solar energy without having to completely switch over.

Your installer can give you an estimate of what your energy bills will look like after you install solar panels.

The average annual savings in Gaithersburg amount to $922.

You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. The sun shines frequently in Gaithersburg, meaning your payback period could last 15.0 years per 5 kW of capacity on the high end.

Although 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.

Yes, solar panels can still provide you with energy during a grid outage. To ensure that your solar system will keep working during a power outage, make sure to choose a quality solar provider and look for a solar system that includes a battery backup.
