1. A method for calculating a real-time effective temperature of a solar photovoltaic module at any operating time during power generation period between a daily wake-up time and sleep time of said solar photovoltaic module, based on a formula as follows:
a. Measuring a solar photovoltaic module open-circuit voltage at said daily wake-up time
b. Measuring the solar photovoltaic module open-circuit voltage at said operating time
c. Measuring an ambient temperature at said daily wake-up time by measuring a temperature of an electronic circuit performing real-time electrical measurements at said daily wake-up time, said electronic circuit co-located with said solar photovoltaic module during power generation operation
d. Subtracting said solar photovoltaic module open-circuit voltage at said daily wake-up time from said solar photovoltaic module open-circuit voltage at said operating time
e. Dividing the resulting voltage value from the prior step by a pre-specified temperature coefficient constant of said solar photovoltaic module, and
f. Adding the resulting temperature value from the prior step to said ambient temperature at said daily wake-up time to provide said real-time effective temperature of said solar photovoltaic module at said operating time during said power generation period.
