We have all seen the classic blue solar panels on rooves across the country. But you may have seen a slow rise in sleeker, better looking black solar panels and thought to yourself, what’s the difference between them? And-should I go for blue or black?
The difference between black and blue solar panels is the way that they are made. All solar panels are made from silicon crystals as this is one of the best materials available for converting sunlight into energy for your home. Without going into too much of the nitty gritty details, black solar panels are more complicated to produce than blue ones. The differences in production essentially mean that a black solar panel is made up of lots of single crystal solar cells put together, and a blue panel is made up of lots of multi crystal solar cells put together.
Because light interacts differently with single crystal (or monocrystalline) cells than it does with multi crystal (or polycrystalline) cells, this is what makes black solar panels look black to the naked eye.
Theoretically this is true, in fact, black panels do absorb more light than blue ones. BUT, and it is a big but, solar panels get warmer as the day goes on. The more light they absorb the more heat they absorb too, and when solar panels get too warm they start to lose how effectively they convert sunlight into electricity, making them less efficient.
