Customer ServiceIt is calculated by multiplying incidental radiation flux or sunlight received on that particular surface area by the size of solar panels in square meters. The received value is then divided by the maximum wattage of
Customer ServiceThe calculated data were validated using the photosynthetic photon flux density sensors. To calculate the photosynthetic photon flux density under the solar panels, it is essential to weigh the direct and diffused components shaded by the solar panels separately because they have different spectrums.
To calculate the PPFD under the solar panels, it is essential to weigh the direct and diffused components shaded by the solar panels separately because they have different spectrums. A method to quantify the shading by solar panels and their supporting tubes for the direct and diffused component as the sun moves was explored here.
However, even when the amount of solar irradiation was measured for several hours at sunrise, the PPFD under the solar panels remained zero. It is possible that the calculated value did not reflect the effect of the shading material on the eastern side.
To eliminate the influence of nearby buildings' shading on the accuracy of the experimental results as much as possible, a building rooftop with high and open surroundings was selected as the experimental site. The rated power of the photovoltaic panel is 305 W, and the tested efficiency under standard conditions is 17.86%.
To evaluate this trend numerically, the measured and calculated photosynthetic photon flux densities were compared using the standard residuals. Generally, the similarity of the two values is confirmed by a standard residual value between −3 and 3.
The simulations must be conducted in terms of the photosynthetic photon flux density (PPFD) rather than the irradiance used commonly in photovoltaic technology simulations. Further, it is essential to estimate the PPFD under the solar panel instead of that above the solar panel to predict agricultural production accurately.
