How to expand solar power without using precious land | PNAS
To generate as much energy as a conventional 1-gigawatt power station, an array of solar photovoltaic (PV) panels needs to cover about 80 square kilometers of land. Unsurprisingly, solar development faces increasingly organized resistance from many rural communities and activist groups, who see it as an enemy of farming.
Homeowners and businesses must be confident that the solar panels they install will not degrade in performance and will continue to reliably generate electricity for many years. Utilities and government regulators want to …
In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) strike solar cells. The process is called the …
How to clean solar panels: 5 tried and tested ways
