How To Choose the Best Solar Company in Rockville

The cost and effectiveness of solar panels often rely on the provider that installed them. Consider all of these criteria in your company search.

Licensing and Training

A Maryland solar photovoltaic installation team must include a Home Improvement Commission-licensed contractor and a master electrician with at least seven years of experience. The contractor installs the panels, while the master electrician pulls permits and connects the system to the grid. If you're installing a solar water heater, your contracting team must include a master plumber for utility connections and permits. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar industry's most trusted trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Rockville

Your solar panels' style will impact how much power you can produce. Monocrystalline panels perform the best but cost the most. Polycrystalline panels generate less, but they're a great traditional option for low budgets. Thin-film panels have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

Additional system add-ons, such as battery storage and electric vehicle (EV) chargers, will raise your overall costs. However, they might make your solar system more efficient and convenient to use. Not every solar contractor provides these extras, so look for a company that installs them if it's crucial for you.

Generally speaking, it costs about $17,700 for a five-kilowatt solar array in Rockville. This table lists more specific costs for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,322
Solar Polycrystalline$1,031
Thin-Film$603
Solar Battery$846
Solar Home EV Charger$3,173

Financing Solar Energy in Rockville

There are a plethora of ways to pay for a solar energy system, and the right one will lower your costs. A few of the most common options include cash payments, power purchase agreements (PPAs), leases, and loans. 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 runner-up option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) allows you to pay a monthly rate determined by the energy you use, like an electric bill. We usually don’t recommend these two options because you won't own the solar system and are disqualified from using solar incentives. We recommend working with an installer that offers multiple financing options. Talk to each agent about what's available, and secure more than one estimate for the best odds of staying within your spending limits.

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

The IRS allows you to claim a 26% federal tax credit on your new solar panels, so long as you purchase it before 2032. Local governments and utilities might also offer their own incentives, financing programs, and rebates that could save you more money.
