FAQ


How do solar panels work?
Solar panels directly produce electricity from sunlight and use an inverter to change the direct current (DC) power they produce to usable alternating current (AC) power. At that point, you either use the electricity in your house or send it back to the electric grid.


How much does a solar panel system cost?
Every rooftop is different, and solar installers in your area can provide the best information on what it will cost to go solar for your home or business. Once potential solar customers begin exploring their options, they often find that the total up-front cost of solar is less relevant than the financing terms, return-on-investment, and cash flow calculation.


What are the financial benefits of solar energy?
On average, installing monitored safety and security devices in your home can reduce your homeowner’s insurance up to 20 percent.

How does solar impact my property values?
Studies have shown that homes with solar energy systems sell for more than homes without them. However, your property value will only increase if you own, rather than lease, your solar panel system. In most parts of the country, going solar will actually increase your property value more than a kitchen renovation.


How much does it cost to maintain solar panels?
Solar panel systems are made of durable tempered glass and require little to no maintenance for the 25 to 35 years that they will generate power. In most cases, you don’t even need to clean your solar panels regularly.

What happens to solar panels when it’s cloudy or raining?
Photovoltaic panels can use direct or indirect sunlight to generate power, though they are most effective in direct sunlight. Solar panels will still work even when the light is reflected or partially blocked by clouds. Rain actually helps to keep your panels operating efficiently by washing away any dust or dirt.


What’s a solar lease or solar power-purchase agreement?
In a solar lease or solar power-purchase agreement (also known as a “PPA”), a customer pays for the solar power system over a period of years, rather than in an up-front payment. Often customers can purchase solar for little or no money down, and often realize energy savings immediately. In a power-purchase agreement, a customer agrees to purchase all the energy from a solar system over a fixed period of time.


What is net metering?
Net metering is the system that utilities use to credit solar energy system owners for the electricity produced by their solar panels. With net metering, you only pay for the electricity that you use beyond what your solar panels can generate. Net metering policies differ from state to state – from Massachusetts to California to Hawaii – so make sure to do your homework ahead of time.


What are the environmental benefits of solar energy?
Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems.


What happens if there is snow on solar panels?
Solar panels convert sunshine into power, so if your panels are covered in snow they can’t produce electricity. Snow generally isn’t heavy enough to cause structural issues with your panels, and since most panels are tilted at an angle the snow will slide off. If snow does accumulate, your panels are easy to clean.


Will I still receive an electric bill if I have solar panels?
Unless your solar energy system includes battery storage and you are fully off the grid, you will still receive a bill from your utility. However, you can dramatically reduce your bill, or even cut the amount you owe to $0, with a solar panel system that matches your energy use.


Should I buy or lease my solar panel system?
The decision to buy or lease your solar energy system depends on your reasons for going solar. If you are interested in maximizing the financial returns of your solar energy system, buying the system is probably a better decision for you.
