Using snow to demonstrate the scalability of home solar PV.
Learning about home solar energy from people that already have an installed system is one of the best ways to see if it is something that you would like to do. The type and manufacturer of the solar panels, how they are installed , wired and maintained are all important aspects of the performance of the home solar system.
Here is a video from a home solar owner showing the impact of snow on their system and the effect on the generated power by cleaning one panel at time. A great example of scaling a solar energy pv system by simply cleaning snow.
