    How solar cells work!

    Each solar cell under full illumination generates about 0.6 volt. Two in series generate about the same voltage as a flashlight cell. Therefor thousands of cells have to be joined to get a meaningfull voltage and current. and each connection is a liable failure point. Then the voltage has to be stored using batteries with all their problems. Then you need an inverter to change the dc voltage to AC and step it up to 115 volts. A lightning strike nearby can wipe out the inverter in a microsecond.Solar is wonderful for powering remote systems far from the grid that require intermittent power.
