Ever since 1839 (when scientist Edmond Becquerel first recognized the PV effect when he realized power generation from an electrolytic cell increased after exposure to light) solar has been growing drastically. Still, at the same time, the price of solar panels has dropped over 70% in the last 10 years and it is predicted to decrease by about 34% by 2030.

It is estimated that by 2050, solar will account for roughly 36% of global electricity generation. This, in addition to other forms of renewable energy, like wind and hydro, will help nations reduce their reliance on fossil fuels and transition to a clean energy economy.

Employment of solar photovoltaic installers is projected to grow 27 percent from 2021 to 2031, much faster than the average for all occupations. About 2,500 openings for solar photovoltaic installers are projected each year, on average, over the decade.
