calculations in solar energy
Calculations The following are considerations and suggestions for choosing the size of solar module needed for your application. The discussion is divided into 2 main parts: (I) Direct use of power from the module and (II) applications including battery storage to insure the availability of power when the module is not generating power. These calculation examples are for using PowerFilm's OEM modules, but could be used as a basis for further solar system development. Key Concept: Module operating voltage is relatively insensitive to the light intensity, dropping about 5% in 10% of full sun. Module current increases nearly linearly with light intensity. Definitions I usage I usage = I app * hours used Power point The operating voltage and current which produce the maximum power from the module. (Forcing the module to operate at a higher or lower voltage results in a less efficient operation). AM1...
