Well regardless of owning your own home or not you are doing a service to yourself to learn the solar way. It is amazing to be able to produce your own power. Eventually when the battery system comes down in cost and gets more efficient I will look into adding it. As of right now I would basically need a section of my basement dedicated to the batteries. LOL not ready to give that up yet.
Exactly, what surprised me the most is, that even with this little space I use with my solar panels (in sum only about 1 square meter panel) and a lame panel efficiency of only about 16%, I still manage to put this energy to good use, I really feel the effect they have on what devices I use and how I think about energy. (I can constantly power small devices like tablets, mobile phone, a few led lamps and 2 laptops, and I have done so for the last 3 years. Total investment about 1300$, but I overdone the redundancy a little bit (buying controllers and batteries three times). It could be done cheaper. But redundancy is important to me.)
Now imagine if one day this square meter runs with an efficiency of 40%? Or maybe 50%? This would bring in 3 times more energy than is available just at my small 4 window seats... that's incredible. With your roof you could power 3 houses all running mining equipment.
This is just the beginning. Cheap commercial Solarpanels just need to raise their efficiency from <20% to >40% while staying cheap and we will have a worldwide revolution.
