How much sunlight should the panels receive?

The amount of energy in sunlight that a solar PV 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 panels so they receive good exposure to direct sunlight.

Your accredited solar system designer/installer will calculate the amount of energy generated by the solar PV panel from the peak sun hours available. This means your installer should be able to tell you how many kW/h your chosen solar system will generate in your particular installation situation. Ask for this estimation in writing before the installation. Peak sun hours vary throughout the year.
