Solar Intensity Data Log

K. K. Abdul Salam, Jidhin Jayan, R. Syamkumar

Solar energy is the most renewable and reliable form of energy available to mankind. All renewable energies, other than geothermal and tidal, derive their energy from the sun. Accurate measurement devices for solar energy are not available. Devices like pyranometer are capable of measuring solar intensity but, they fail to draw the exact picture of the incident energy. These facts are considered in this work to design a device which is more reliable and efficient than the existing devices. This design presents a device to measure the solar intensity at a specific location and time, using a photovoltaic cell and a microcontroller based circuitry, which is interfaced with a personal computer.
