Frequently Asked Questions

Common Questions About Solar Panels In Illinois

Still have questions about getting solar panels installed at your home or property in Illinois? Browse some of our most common questions and answers below.

How do solar panels work?

Solar panels, or solar photovoltaic panels, transform sunlight into usable energy by converting the light into an electric field that then flows into a conductive wire.  The conductive wire flows into the inverter which then transforms the electricity to an alternating current which can then be used to power a property.

You can read our full article about how solar panels work here.

How are solar panels made?

Solar panels are comprised of an array of solar cells (photovoltaic cells). These cells, made of silicon semiconductors, absorb sunlight to create electricity and then transfer the energy into the inverter. The cells are then networked together inside of a case along with some other components to create the panel. You can read more about how a solar panel is made in this article.

Can Solar Panels Withstand Hail Storms?

Yes! Properly installed solar panels are much more resilient than people imagine. Just because they’re thin and reflective like glass doesn’t mean they are fragile. In fact, many solar panel owners report extensive damage to the rest of their home, cars, and property, while their solar panel system stays undamaged. The angle and direction the panels are installed facing make the biggest difference regarding their vulnerability during a hail storm, and like the rest of your property they can be insured against hail damage.

How long do solar panels last?

Solar panels have a typical lifespan of 25 to 30 years. Once solar panels reach this point they begin to decline in efficiency. However, with recent advances in solar panel technology, it could make more sense to replace your solar panels in 10 years to maximize the improved efficiency.

How Is Solar Energy Produced?

When the photons in sunlight hit the atoms in your solar panel, electrons can be kicked loose. Solar panels are designed to collect these disassociated electrons and store them in a battery to power your home and electronics.

How many solar panels can I fit on my roof?

On average, you can fit about 25 to 28 solar panels for every 500 square feet of roof space. However, in some cases, homeowners will not be able to utilize the entire roof space due to shading or roof grade.

How Often Should Solar Panels Be Cleaned?

The simple answer is any time they become obstructed by too much debris or grime to work efficiently. How long that takes will depend on your location. If you live near a populated downtown, your panels will get covered in soot faster, but if you live in a rainy place, your panels may stay cleaner longer. As a general rule, it is best to clean and inspect your solar panels every 6 months, but you may find it makes sense to clean them more often and get full efficiency from your clean solar panels.
