  • Warranty and service offerings: Solar contractors should stand behind their equipment and services with warranties. We evaluated how each contractor responds to issues and warranty claims, focusing on promptness and customer happiness.

Benefits of Solar Energy

Solar energy offers multiple benefits. Here are some highlights.

  • Lower energy bills: Producing some or all of your own power will save you money on your electric bills long-term. Plus, some states offer net metering programs that allow you to sell your unused energy back to the grid, generating extra credits toward your energy bill.
  • Better energy independence: Solar panel systems with battery backups and storage systems operate through power outages and emergencies, and you won't have to depend on the power grid for your safety and well-being.
  • Reduced carbon footprint: Embracing solar is a surefire way to minimize your carbon footprint and home fossil fuel dependency.

How To Choose the Best Solar Company in Annandale

Choosing a company is the first step toward an effective and cost-efficient solar system. Consider all of these aspects in your business search.

Licensing and Training

Since 2012, the Virginia Department of Professional and Occupational Regulation has issued Alternative Energy Systems (AES) licenses to contractors working on solar PV systems. A contractor with an AES license may need to subcontract plumbing, electrical or HVAC work. You should also visit a company's website to learn about its private accreditations. Two of the most respected are the Solar Heating Installer and PV Installation Professional certificates, granted by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Annandale

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power and generally have the highest quality. 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 battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can maximize your solar system's performance. Not all solar companies provide these extras, so look for a contractor that installs them if it's a priority for you.

Generally speaking, it will cost about $17,950 for a five-kilowatt solar array in Annandale. This table displays more specific prices for different solar panel types and system components in your area.

Solar Panel CostAverage 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 optimal financing solution will influence your overall solar system cost and possible savings. Common payment options include loans, leases, power purchase agreements, and cash payments. Though it involves a large up-front payment, cash is the most economical choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the second most effective option. As with a car or home loan, 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 won't own your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. We suggest working with an installer that offers multiple financing options. Ask each agent about what's available, and obtain more than one estimate for the best odds of keeping within your financial plan.

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

You are eligible for a 26% federal solar tax credit for new solar power systems until the year 2032. City and state officials and utility companies might also offer rebates, discounts, and dedicated financing plans that could save you more.
