how the energy of load connected to solar PV measure.?Want too the basic idea about it.The role of current flowing thrugh the load?Can u explain with example..can explain simply?Im not an electrical student so explain very basics
A solar panel is made up of solar cells. Each cell produces about 0.5 to 0.6 volts. Cells are connected in series, like the batteries in a flashlight. Enough cells are placed in series to produce the desired voltage. Cells produce very little current, so many strings of cells are connected in parallel to produce sufficient current. The output is direct current (DC), like that from a battery. A home solar system needs alternating current (AC), so an inverter is used to change from DC to AC. Some systems have batteries for backup power. In these some of the DC output is used to keep the batteries charged. Systems are measured in kilowatts. System sizes are chosen to meet the demands for electricity. My system has a 6 kilowatt (kW) rating. The true output is more like 4. Now that you know this much you can Google SOLAR SYSTEMS to learn more.
Most PV solar panels are labelled with their peak power output - this is the maximum power (measured in Watts) which that panel can generate in full sunlight. Remember these simple formula- V=IR and P=VI The current flowing through load keep the flow of electrons and thus energy is produced.
