According to the manufacturing standards, 25 °C or 77 °F temperature indicates the peak of the optimum temperature range of photovoltaic solar panels. It is when solar photovoltaic cells are able to absorb sunlight with maximum efficiency and when we can expect them to perform the best.
To get the best out of your photovoltaic panels, you need to angle them towards the sun. The optimum angle varies throughout the year, depending on the seasons and your location and this calculator shows the difference in sun height on a month-by-month basis.
At 25°C, solar photovoltaic cells can absorb sunlight efficiently and achieve their peak rated output. However, real-life conditions are far more dynamic anyway. The solar panel output fluctuates in real life conditions. It is because the intensity of sunlight and temperature of solar panels changes throughout the day.
The optimal tilt angle of photovoltaic solar panels is that the surface of the solar panel faces the Sun perpendicularly. However, the angle of incidence of solar radiation varies during the day and during different times of the year.
The ideal inclination of the photovoltaic panels depends on the latitude in which we are, the time of year in which you want to use it, and whether or not you have your own generator set. In winter, the optimum angle si close to 50º, and in summer, the ideal angle is around 15 degrees. However, some conditions can alter this premise.
Therefore, the angle can be calculated from the formula: Knowing the minimum angle of incidence of sunlight during the year, it is possible to determine the distance between successive rows of photovoltaic panels. The figure below shows the schematic diagram used to calculate the row spacing and the formula for the calculation:
