How is PSH calculated? Peak solar hours refer to the number of kWh/m2 of sunlight that reaches a certain intensity. For example, a PV system produces 1000 watts/meter2 of power for one hour. Then, it generates 0.5 kWh/m2 of power for the next five hours. This means that 5 hours of sunshine equal one kWh/m2. This value is important when calculating PSH.
Peak sun hours (PSH) are the number of hours during which the intensity of sunlight reaches 1000 watts/m2. An hour of 1,000 watts/m2 is considered to be a PSH. So, if the amount of sun you receive is 500 MW/m2, then you would get 25 kWh of power per day. Depending on your location, the peak hours will vary from area to area.
Peak sun hours are not the same as hours of sunlight. They are the average solar radiation throughout the day, measured in kWh/m2. A single peak sun hour can generate anywhere between 700 watts/m2 of power. This is important because most people will only use their solar system during the peak hours, when the sun’s rays are the strongest. This is also true for high-altitude locations.
Peak sun hours are an important indicator of how efficient a solar panel is. Those in high-altitude regions of the world experience more sun than they do during their winter months. But when it comes to determining the peak hours, the answer is not as simple as counting watts. In the US, the sun’s rays are at their greatest between 10 a.m. and 4 p.m. And the intensity increases as the altitude increases.
