travels across the sky during daylight hours. Once again, other installation angles still produce considerable amounts of power and attract significant tariff income.
This is the angle at which the photovoltaic (PV) panels are installed to the horizontal (see the image below). The ideal angle for panels to be installed is 30 degrees to the horizontal as this will provide maximum exposure to the Sun as it travels across the sky during daylight hours. Once again, other installation angles still produce considerable amounts of power and attract significant tariff income.
Most domestic roofs on which you would install your PV system are built at around 30 degrees to conform to building regulations and roof strength requirements. Commercial roofs are often different, so use the income calculator with different roof slope angles to see the differences in electricity and income generated from differing array installation angles.
