Correction: Monocrystalline and Polycrystalline Solar Panels

We've made a quick correction to the article on solar panels we published last Friday, with updated information on the different types of technology available.

Here's what the article now says:

You should look for a solar panel with a surface that's all the same colour. It depends. Monocrystalline panels are usually one single, solid colour, and offer the best output performances. However, they're also the most expensive type of solar panel. In descending order of both output and price, it goes monocrystalline, then polycrystalline and then amorphous, which is the kind of basic solar cell found in solar-powered calculators, for example. Polycrystalline panels therefore make a good compromise. So how can you spot one? If you look closely at the surface of a polycrystalline solar panel you'll see different coloured patches, like in the picture below:


So basically, monocrystalline solar panels are better than polycrystalline solar panels for output. However, they are also more expensive to produce.

Sorry for the confusion, and many thanks to Paul for bringing our attention to the problem via e-mail.
