Solar Collector Power Output





How much power do solar thermal collectors produce?

When planning for a solar thermal system, it is critical to consider the available solar radiation at the installation site.

Solar radiation is a highly variable power source. Radiation varies significantly from hour to hour, day to day, and location to location, based upon time, weather and geographic region.

It is critical to note that solar thermal collectors have a variable efficiency, dependent upon solar radiation intensity, fluid temperature, and air temperature.

Contrary to photovoltaics , using monthly averaged solar radiation data cannot be used to accurately simulate the output of solar thermal collectors.

, using monthly averaged solar radiation data be used to accurately simulate the output of solar thermal collectors. In order to more accurately understand solar collector output a numerical model has been developed which simulates the power output of solar thermal collectors using 15 years of historical hourly solar radiation and temperature data from NREL. This takes into account the variation in efficiency of the thermal collectors.

Due to the variable nature of the weather in any location in the world, it is nearly impossible to predict future weather conditions. This tool aims to provide statistical insight on how a solar collector might perform based upon a historical simulation of solar collector power output. Using this historical simulation, it is the system designers responsibility to make an engineering judgement how the solar collector will perform in the future.

The "theoretically perfect collector" is the incident radiation on the tilted surface and provides an upper limit on what a perfectly efficient solar collector could do in the configuration selected.
