Neural Network Solar Irradiance Sensor

"NOVELTY - The apparatus has a temperature sensor fixed with a photovoltaic (PV) cell. A controller is coupled with the PV cell. The temperature sensor determines PV current, PV voltage and temperature of the PV cell. The temperature sensor detects presence of irradiance at the PV cell based on PV current and PV voltage. The controller comprises a neural network algorithm. A voltage determination circuit is coupled between the PV cell and the controller. The voltage determination circuit is equipped with a test resistor. The test resistor is coupled with output terminals of the PV cell.. . USE - Solar irradiance sensing apparatus for a PV array system and a PV power plant.. . ADVANTAGE - The apparatus improves efficiency of a PV power plant. The apparatus has simple structure, better sensing accuracy and low manufacturing cost. The apparatus effectively avoids need of a solar irradiance equipment.. . DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a PV array maximum power point tracking (MPPT) method.. . DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating relationship between current and voltage of a solar irradiance sensing apparatus.. "
