Most of the solar PV never installed the lightning protection.

It is much troubled in Japan. We are the country for the lightning strikes. We have many lightning damage which are US$1trillion annually. And the part of the solar PV is 25%.
If the manufacturer knows it, they never lose the end-user’s credit. But I know what it is better. However it is better than nothing.


Announced that Solar Frontier attained 19.7% of the energy conversion efficiency! Can you believe?

It was announced that the solar frontier attained 19.7% (it measures in the National Institute of Advanced Industrial Science and Technology) of the energy conversion efficiency which serves as a world record as a cell (about 0.5 square centimeter) of the thin film solar cell which does not contain cadmium in response to joint research with NEDO.

This world record is what was realized in the chip started from the cell which wad cut from 30-cm square board ,which were not developed for small area, and explains that proves the potential height of the future formation of large area in the company.
