"I had thought about installing solar panels on my rooftop for several years.  However, the high upfront cost was a big obstacle for me. I had read articles mentioning that the cost of installing solar panels for residential customers in Japan is more than twice the cost in Germany.  Moreover, I wasn’t an expert in solar power and wasn’t sure how long it would take before my investment would pay off. I also worried about what I would do if the panels broke or malfunctioned. So we started Hot Denki with the clear goal of removing all of these pain points and accelerating the widespread adoption of solar power in Japan. " ~ Jeffrey Char
