Common Questions

Solar panels convert sunlight into electricity using the photovoltaic effect. Sunlight excites electrons in the panels to produce direct current (DC), which is then converted into alternating current (AC) for homes and businesses.

Solar panels still generate electricity in rain and cloudy weather, but at lower output—typically 10–25% in heavy cloud and 30–50% in partial cloud. They rely on daylight, not heat, and often perform efficiently in cooler temperatures.

In most cases, solar panels do not require planning permission, as they are classed as permitted development if they meet certain conditions, such as height limits and conservation area rules.

Solar panels typically last 25–30 years, although many continue generating electricity beyond this with gradually reduced efficiency.
