How To Choose the Best Solar Company in Annandale

The cost and efficacy of solar panels often hinge on which company installed them. Make your choice based on the following vital factors.

Licensing and Training

Since 2012, Virginia's Department of Professional and Occupational Regulation has issued Alternative Energy Systems (AES) licenses to contractors who install solar PV systems. Even if a contractor has an AES license, they may still need to subcontract HVAC, electrical or plumbing work. Solar providers can also pursue certifications from trade groups and standards organizations. The most prestigious ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in Annandale

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. Polycrystalline panels provide a lower price point but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

You can also add electric vehicle (EV) chargers and battery backup systems. These will increase your total project price, but they can boost your solar system's efficiency. Not all solar companies provide these extras, so look for a company that installs them if it's crucial for you.

Generally speaking, it costs about $17,950 for a five-kilowatt solar array in Annandale. This table shows more specific pricing information for different solar panel types and system components in your area.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,205
Solar Polycrystalline $940
Thin-Film $550
Solar Battery $771
Solar Home EV Charger $2,893

Financing Solar Energy in Annandale

Choosing the right financing solution will influence your overall solar system cost and possible savings. Common payment options include cash payments, loans, leases, and power purchase agreements. Though it requires a large up-front payment, cash is the most affordable choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the next best option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for money-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a power purchase agreement lets you pay a variable rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be suitable in specific circumstances. We advise working with an installer that offers multiple financing options. Talk to each agent about what's available, and get more than one estimate for the best odds of keeping within your spending limits.

The table below lists the average payback periods for different capacities of solar systems in Annandale.

You are eligible for a 26% federal tax credit for new solar energy equipment until the year 2032. Local and state governments and utility companies might also offer rebates, discounts, and unique financing solutions that could save you more.

Solar System Capacity Estimated Payback period
1 kW 2.3 years
2 kW 4.6 years
5 kW 11.6 years
10 kW 23.2 years
