Which is better, fireman or photovoltaic builder?

1. The personnel on duty at the photovoltaic power station work in three or four shifts. At work, he was monitored by the computer, filling out forms and recording the situation on duty. The main reason is that he has little responsibility, less power generation during the day and less power generation at night. When he goes to work, he goes to the construction site for inspection. Photovoltaic work has no noise, he can wear clean clothes and the treatment is acceptable.

2. The construction site of the fire builder project is remote and windy, with poor environment, tired work, high intensity and uncertain factors.
