The amount of sunlight that a solar panel receives over a day is expressed in peak sun hours. As the amount of energy generated by a panel is directly proportional to the amount of energy it receives from sunlight, it is important to install solar panels in a way to maximise sunlight. One of our solar energy team will calculate the amount of energy generated by the solar PV panel from the peak sun hours available. Peak sun hours vary throughout the year and will also vary depending on where you live.
