Please find the following as an explanation of basic photovoltaics and how to provide the best solar light location for the sun’s energy. “Think that your car park is a desert island. The island has four sides.” What is the best direction a solar panel should point? This in essence is how the solar lighting system needs to work to obtain the maximum available energy from the sun. So by pointing the solar panel south it will create the greatest amount of energy when in the Northern Hemisphere. But if you pointed the panel north, west or east solar light location would be at a reduced level of irradiance, which can cause a reduction of 15-20%, a fraction of the available sun’s power.
This is in essence the basis of positioning solar car park lights correctly. We also have to take into account panel angles, building, or foliage shading when making an assumption to the amount of energy that can be stored into a battery bank. So to increase any solar gain at locations to its maximum. It is important to understand how to capture all available sunlight, over a given time period.
This is where we understand the peak performance available when using the Azimuth of the sun at your location. Our company have been working with solar energy and battery storage over the last 20 years. As such we fully understand the geographic location needs required to ensure maximum solar irradiance is utilized when illuminating exterior car parking areas and public footpaths surrounding the adjacent parks.
