Solar panels work by converting sunlight directly into electricity through a process called the photovoltaic effect. When photons from sunlight strike the silicon cells inside a panel, they knock electrons loose and set them moving in a controlled direction — that flow of electrons is electricity. The panel itself produces direct current (DC), which an Read more »

Solar panels require minimal maintenance, but regular cleaning is one task that significantly impacts long-term performance. Dust, pollen, bird droppings, leaves, and other debris accumulate on panel surfaces, reducing the amount of sunlight reaching the photovoltaic cells. In dry climates or regions without frequent rain, soiling can reduce output by 3-5% annually, and in extreme Read more »
