Shading on Solar PV Array

If the solar array is shaded in any way, its power output will be reduced. If there is continuous shading at the same position on the solar modules, the modules can develop ‘hot spots’ that can damage them permanently. Incidental shading is not static, as it moves throughout the day and year, following the sun’s […]

Solar Array Positioning

A solar module will receive the most solar radiation and produce the greatest amount of power if it faces directly to the sun; however, the sun moves throughout the day and the year. Daily movement: Each day, the sun moves from the east, where it rises, to the west, where it sets. The compass position […]

Configuring PV Array

A solar array is the electrical combination of several solar modules. The power output of this array will be the sum of the power outputs of the combined solar modules. The method by which the solar modules are configured will determine the electrical output characteristics (namely, current and voltage) of the solar array. Solar modules […]
