Newly published data from the Federal Energy Regulatory Commission (FERC), reviewed by the SUN DAY Campaign, reveal that solar accounted for over 75% of US electrical generating capacity added in the first nine months of 2025.
The magic happens through the photovoltaic effect - a process where semiconductor materials generate electrical current when exposed to light. When photons from sunlight hit silicon atoms in solar cells, they knock electrons loose, creating a flow of electricity.
China's solar power generation overtook wind for the first time last year as a boom in cheap panels continues to reshape the country's grid and climate trajectory.
This is one of the top advantages of solar jobs: every task, from site prep to maintenance, supports cleaner air and lower carbon output. Workers often start with basic tasks and build experience.
In solar panel installation, piles typically measure anywhere from 7 feet (2. Photovoltaic facilities average 500 steel piles per megawatt, and projects with more than 100,000 steel piles aren't uncommon.
