A solar panel is an integrated array of photovoltaic (PV) cells, usually a single solar cell.
The panels are mounted on a base, usually around the edge of a roof, and are used to produce electricity.
They can also be used to generate power from waste heat or as a backup generator.
Solar panels have been around for a while now.
But until recently, there wasn’t much evidence to show that they were actually better than fossil fuels.
It turns out that solar panels are more efficient at converting solar energy into electricity, and at producing a much bigger amount of power than previously thought.
In fact, in recent years, solar panels have improved their efficiency by a factor of three or more.
So, while the solar panel industry has enjoyed the best of times, it’s also now facing the worst of times.
