Solar Panels In North Carolina

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.

Flexible solar panels are limited in the materials they can be made from. Rigid solar panels can be made with more efficient components, and are generally thicker, which means more material to interact with solar rays and produce electricity.

In order to figure out how many solar panels you need, you’ll need to determine how much energy your household uses, how many panels you can fit on your roof, the peak sunlight in your area, how efficient the panels you’re considering are, and whether net metering is available in your area. The easiest way to find out is to get a solar panel estimate from a local installer.

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.

Snow and Ice are rarely an issue for a properly installed and maintained solar panel system. Solar panels generate a good amount of heat through their operation and will usually melt any snowfall or ice accumulation. Solar panels are also almost always installed at an angle so snow and ice will generally slide right off. If your panels become entirely blocked by snow or ice, however, they will not generate power, the same as with any other debris that might cover your panels.

Modern solar panels are usually about 15% to 18% efficient. This means that 15% to 18% of the sunlight they absorb gets turned into energy. The remaining sunlight is lost as heat, warming the solar panel casing. That being said there are a number of factors that can impact the overall efficiency such as the solar panel age, materials they’re made with, and average sun exposure.
