Solar power is a highly promising decarbonization technology, and it has received a fresh boost from a Japanese company that designs and constructs roofs. Large area on factory roofs would be ideal for solar panels but are not strong enough to support the weight, so the company collaborated with electrical equipment makers to develop new technologies. One is a rail system that allows regular panels to be fitted on corrugated roofs, the other is a thin-film panel that can be mounted on even weaker roofs. Profits made from solar panels in Japan subsidize projects to bring electricity to rural schools in countries with poor infrastructure.
