Solar FAQs: Top Solar Questions, Answered
If you're installing a solar system on your home, it makes sense that you're probably wondering how it converts sunlight to energy and what happens when events like blackouts occur. We've got all of the answers you need right here.
How do solar photovoltaic (PV) panels work?
Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity in your house or send it back to the electric grid.
Do my solar panels produce power when the sun isn't shining?
The amount of power your solar energy system can generate depends on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy and no energy at night. However, because of high electricity costs and financial incentives, solar is smart even if you live in a cloudy city.
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.
Can I go off-grid with solar panels?
When you install solar panels on your property, you will still be connected to the grid. This allows you to draw from the grid when your system is not producing all the power you need and send power back to the grid when you produce more than you use. It is possible to go off the grid with a solar energy system that includes battery storage. Still, it will cost significantly more and is unnecessary for most homeowners.
Do solar panels work in a blackout?
If your solar panel system is connected to the grid, it will shut off during a blackout. This is to prevent emergency responders and electricity utility repair people from being injured by your panels sending power back to the grid. However, there are certain inverters you can buy that provide backup power in a blackout when paired with a battery.
How much will solar panel maintenance cost?
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. If something does happen, most equipment manufacturers include warranties, although warranty terms depend on the company.
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.
