Ever wondered how much solar energy you have where you live? This video explains how to find out the solar power available to you.There's a myth around that you need a hot climate for solar energy to work. Really, you need sunlight for solar panels to work.

So while hot weather can be helpful for your solar hot water, for electricity from the sun, cold weather is fine.
