How To Choose the Best Solar Company in Gaithersburg

The more informed your company research is, the better your photovoltaic system will ultimately perform. Here are some key items to consider while searching for a solar company.

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 handles permits and hooks the system up to the grid. If you're installing a solar water heater, your contracting team must include a master plumber for permits and utility connections. 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 Gaithersburg

The style of solar panels you choose determines how much electricity you can generate. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

If you want to charge an electric car or use your solar power in inclement weather, you can pay extra for accessories. By selecting the right components, you can make your panel array more productive and convenient to use. Not all solar contractors include these optional components, so look for a contractor that sells them if it's essential for you.

You can plan to spend about $17,700 on average for a five-kilowatt solar energy system in Gaithersburg. Check the table in this section to get an idea of how much Gaithersburg solar companies might quote for your specific system.

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 Gaithersburg

Choosing the correct financing plan 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 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 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) lets you pay a monthly rate based only on the energy you use, as with an electric bill. We generally don’t recommend these two options because you won't own the panels and are disqualified from using solar incentives. Look for providers that offer two or more payment plans to find the right fit for your budget.

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

A 26% federal tax credit applies to new home solar systems purchased through 2032. Additional incentives may be available through city and state governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in Gaithersburg

How much energy and money could I save per year by switching to solar?

Most Gaithersburg homeowners spend about $1,670 on energy each year. Your costs could drop by $824.38 for each kilowatt you generate after you pay off a solar array.

How widespread is solar energy in Gaithersburg?

Yes, solar energy is readily available in Gaithersburg. A growing number of area homes already use solar power on-site or through utility grids, and Maryland has about 4854 jobs comprising its solar economy.

Should I expect a property value increase after switching to solar energy?

Yes, a solar PV system will increase your property value. According to the National Renewable Energy Laboratory, for every dollar you save on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

Could I still use solar power if I live in a wooded, rainy, or dark area?

Even if your property has high tree cover, you could still use solar energy. Your installer will optimize your system's performance by choosing the proper site for panels, installing a battery backup system, cleaning them regularly, and positioning them to capture the most sunlight throughout the year. This way, you can keep solar energy longer and use it as necessary.

What is a Gaithersburg solar panel's average lifespan?

Modern solar systems are designed for durability. The average panel lasts at least 25 years. Lower-cost panels tend to have reduced longevity than premium models.

How do I care for my new solar system?

Solar panels don't require much maintenance to keep working properly. All you'll need to do is clean and inspect the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to help you in your system's care.

How can I maximize my solar system's performance?

To enhance your solar system's performance, you can implement the following strategies:
  • optimize the panels' position with your solar installer
  • regularly clean your solar panels
  • upgrade to a more efficient inverter trim or cut down trees in the way of your panels
  • use energy-efficient appliances

What are some "red flags" to watch for as I research companies?

While many online reviews are positive, even the most recommended solar companies might have unhappy customers. You should know these early red flags for the best chances of an exemplary job:
  • Pushy sales approach
  • Not being straightforward about credentials and training, warranties, references and cost
  • "One-size-fits-all" approach
  • Not thoroughly inspecting your site
  • Limited customer feedback
