In the summer months, solar panels can get as hot as 150 degrees Fahrenheit. In the event that temperatures reach those extremes, solar panels typically lose some of their efficiency. On average, solar panels are tested to perform at peak efficiency between 60 and 95 degrees Fahrenheit.
Your solar panels are a lot more complicated than they seem. That’s because they’re made up of layers and each layer has its own special job to do. For instance, the top layer is called the “absorber” and it’s made of tempered glass with a metal film inside. It takes in light from the sun and turns it into electricity, just like you might expect!
One type of solar panel often includes three or four layers aside from the absorber and these are called “cells”. The cell typically on top absorbs sunlight that goes through those cells below it – this is sometimes called “passive cooling”.
Do solar panels work in rain?
There are a few different types of solar panels, each with slightly different performance in different environmental conditions. Rain actually helps by washing away dust and dirt. Below are a just a few common types of solar panels.
How does a solar panel work?
- Sunlight hits the solar panel
- Electricity flows from the solar panel to your device
- Solar panels can actually get hot, so when you install them you need to make sure to do it in the shade!
- The solar panels are protected from the elements by a waterproof tent
- The electrical output from the solar panels is used to charge batteries or run electrical devices in your home.
- You have power!
Do solar panels need maintenance?
A solar panel requires regular maintenance and it’s important to do it. This is so that the cells will continue to work optimally. While rain will help clean dirt and dust, it is recommended to clean them periodically. For solar panels the cell structure might have to be cleaned with a soft brush.
Cleaning a Solar Panel
To deliver the most energy possible, they must be kept clean. Dirt and grime build up can impair performance and shorten the lifespan of the panels, so regular maintenance is a good idea. A soft brush can help you rid them of dust before you begin to clean them. If your panels are mounted on a pole or roof, make sure you can reach all parts of them easily to keep them well-maintained.
Wash the solar panel with soap and water. Rinse well. Let it dry in a sunny area, ideally in direct sunlight. For stubborn stains and dust, use a soft brush or cloth with detergent or vinegar. Do not apply pressure when cleaning. Scrub gently using strokes perpendicular to the solar cells, to avoid damaging them.
How to clean a solar PV panel:

How Much Electricity Does Solar Power Generate?
The “net” amount of electricity generated by a solar system depends on two main factors: (1) the number of hours of sunshine per day in the area in which the system is installed, and; (2) how many watts of output capacity each panel produces.
