Electrical Solar Power

how to design a solar panel to store energy and convert it into electricity?

first, to be totally honest I have no idea about how a solar panel. My task is to create something like a flashlight solar power stored energy from the sun during the day and convert it into electrical energy energy, then the light bulb so that it can operate at night. any ideas on how to design the solar panel? that can store enough enegry or more if no sun, the other day. and cost too: D

solar panels change light into electricity, and do not call the store. You need a solar panel capable of power enough to keep the lights on all night. And it can be 6 hours of sunlight and 12 hours of darkness. Then you need a set of batteries large enough to store this energy. And a charge controller to regulate the charge to the batteries. And then the light will operate on battery voltage, eg 12 volts. This probably not is impractical due to the large solar panel is necessary, and large batteries. But here's a few. Suppose a 100-watt light, 12 volts. Suppose you get at least 6 hours of sun each day and the light will light for 12 hours. This means that the battery has to store 100 * 12 = 1200 watts per hour. divide by 12 and is for 100 amps per hour, a large car battery. Taking into account the loss of 20% in the battery and circuitry, means 1,400 hours nee Watts solar panel. Because it has four hours of operation, which means you have to deliver 1400 / 4 = 350 watts, 15 volts. So this is: 350 watts panel 100 amp hours to load the driver size battery up to 100 watts of light. If you have to allow a day without sunshine, then you need more batteries. Two nights 2,400 watts half-hour, two batteries, a charge controller and a great 2800 / 4 = 700 watt panel. Cost: $ 400 to $ 200 batteries for the controller responsible for the $ panel 2000.
