I'm asking because my uncle has a business of selling and installing swimming pools, he has the electrician working for him and it contemplated the possibility of installing solar panels for his customers (the more sun, the higher electricity consumption in the swimming pool because you need to filter out algaes before they bloom, so it's a perfect match and he has to do the wiring anyway) and the main reason why he abandoned the idea was the cost of the panels themselves.
I feel there's a huge disconnect between the talk about technology and real life. It's like when people keep talking about how battery cost have plummeted in recent years and how they now dirt cheap, yet when you want to buy one, electric cars are not cheaper than 4 years ago.
