What is an acceptable voltage increase given a 10°C temperature drop according to the context?

In photovoltaic systems, the relationship between temperature and voltage is important for understanding how solar panels perform under varying environmental conditions. As temperature decreases, the voltage output of a solar panel increases. This characteristic is quantified by the temperature coefficient of voltage, which indicates how much the voltage will increase or decrease with a change in temperature.

For a typical solar panel, the voltage coefficient is often around -0.3% per degree Celsius. Therefore, if the temperature drops by 10°C, we would expect the voltage to increase as follows:

1. Calculate the total increase in voltage: At a rate of 0.3% per degree Celsius, over a drop of 10°C, this results in a total increase of:
   • 10°C * 0.3%/°C = 3.0%.

This indicates a voltage increase of approximately 3.0%, which can sometimes be rounded to 3.4% depending on the specific characteristics of the panels being used or variations in the temperature coefficient value. However, the context suggests that a voltage increase of around 3.4% is acceptable for a 10°C temperature drop.

Thus, the correct answer reflects the expected performance of solar panels regarding voltage increase due to a decrease in
