Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Going solar can be a great way to lower electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when determining whether a solar installer is trustworthy.
Verify that your solar installer is properly licensed. This help guarantee that the work is done properly using current installation best practices. The installation team for a solar photovoltaic (PV) system in Maryland must include a Home Improvement Commission-licensed contractor and a master electrician with at least seven years' experience. The contractor installs the panels, while the master electrician handles 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 permits and utility connections.
Check review sites like the Better Business Bureau (BBB), Google Reviews, and TrustPilot to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and customer service. Use caution with companies that have very few reviews or mostly negative ones.
Get free, detailed quotes from three to five solar companies. The quotes should describe all costs and identify the solar parts included. Looking at several quotes can help you find the best value for your budget.
Quality solar installations should have strong workmanship and performance guarantees. A workmanship guarantee addresses any installation defects (such as cracks in the panels, poor alignment, or poor wiring), while a performance warranty ensures a certain level of energy production. Strong guarantees show that a company is confident in its work.
Going solar can help reduce your energy expenses over time. Be sure to consider these aspects when judging the cost and value of solar panels.
In Rockville, solar panels cost an average of $3,540 per kilowatt, with an average system size of 5.6 kilowatts. The typical Rockville homeowner spends $13,851 on their solar array after federal tax refunds. An estimate from a local provider will consider additional information reflecting your desired system's capacity, panel type, size, and required preliminary work. In some cases, homeowners may prefer to lease solar panels to reduce upfront costs.

A solar photovoltaic (PV) system can generate power to run any electric appliance or system in your home. More specifically, you can install a solar heating system for your water.
With home solar energy, you can save money on your energy bill, lower your property's emissions, and gain additional energy independence.
Yes, it's possible to use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, so you can reap the environmental benefits and savings of solar energy without having to completely switch over.
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 Rockville amount to $943.
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 Rockville, meaning your payback period could last 14.7 years per 5 kW of capacity on the high end.
Your recommended maintenance will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel once a quarter. Your solar contractor 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 bill credits or payments 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.
The most common types of home solar panels in Rockville include monocrystalline, polycrystalline and thin-film. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Ask your local provider about what kinds of solar panels they work with.
