How To Choose a Solar Company

Putting solar panels on your roof could lower 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 ensures that the work is done properly using the most up-to-date installation methods. Since 2012, the Virginia Department of Professional and Occupational Regulation has issued Alternative Energy Systems (AES) licenses to contractors who work on solar PV systems. A contractor with an AES license may need to subcontract HVAC, plumbing or electrical work.

Read Customer Reviews

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

Compare Multiple Quotes

Contact three to five solar companies to get free, detailed quotes. Quotes should clearly explain all costs and list the exact solar components included. Comparing multiple quotes helps identify the best value based on your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar power can help lower your electricity costs long-term. When considering solar panel's cost and value, be sure to factor in these considerations.

  • Research federal and state tax credits: A 26% federal tax credit on the full cost of solar systems is available through 2032. Many states also offer incentives. These credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Homeowners can pay for solar panels outright or finance payments over time with a loan or lease. Be sure to confirm key details like annual percentage rate (APR), payment schedule, fees, and what ownership means when financing solar panels.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to install solar panels. Check the qualification criteria and rebate values with your local electric company to determine what your savings could be.

Cost of Solar Installation in Herndon

Solar panel costs vary based on system capacity and the technology used. The average solar system in Herndon has a capacity of 8.1 kilowatts. Homeowners in the area should expect to pay around $3,590 per kilowatt; the average Herndon homeowners spends about $20,341 on a new solar array after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower upfront costs.) A personalized quote from a local solar provider will account for factors such as the panel type, size, and capacity of the planned system, and should include costs for permit fees, labor, and preliminary work.

Frequently Asked Questions About Solar in Herndon, VA

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

There are many advantages of home solar energy. You can reduce emissions, raise your property values, and save money. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages.

Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Herndon amount to $1,448.

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 Herndon, meaning your payback period could last 14.0 years per 5 kW of capacity on the high end.

The specific required maintenance steps will vary based on the type of solar panels you have. At a minimum, you should clean and inspect each panel every three months. Your solar installation company might offer comprehensive plans where they'll do the maintenance for you.

Net metering is a power purchasing policy that allows solar energy system owners to receive compensation for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.

While solar energy might not be the best option for some in wet or dark areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.
