While an interesting experiment, trying to calculate ROI on an a small/inefficient system isn't a very useful metric.
- You can get panels for USD $0.38/watt (vs 0.81 in the article), or used for 1/2 that.
- Non optimal angle, no mention of what direction the balcony is facing
- Standard grid tie systems use microinverters
- ozim 5y agoIt is useful for me. I have a flat and a balcony, it would not be possible for me to have anything bigger than author. I don't have to run such an experiment and I already see that any "backup power" shizzle I would buy on amazon would be loss of money. Better get small fuel generator for any blackouts that can happen.
- petre 5y agoWell, apartment buildings roofs are empty and only collect heat in the summer. Why install solar panels on a balcony?
- AnonymousPlanet 5y agoBecause most people don't own the apartment building they live in.
