Your Questions About Solar Generators For Home Use

George asks…

How does an electric inverter used at the tail end of wind generator stay in phase with the power company.?

how does an electric inverter used at the tail end of either home solar panels or wind generator stay in phase with the incoming household current. It would seem to me that if the phase was just slightly out of time with that from the power company, much of the power produced would be lost.

admin answers:

The best inverters use a pulse-width-modulated output and a low-pass power filter for the line frequency (60 Hz or 50Hz). The high voltage DC input is modulated at a rate in the 20-40 kHz range or even higher. The modulation is controlled directly by the line to which the power is fed into. Some of these inverters can run in the high 90% efficiency range.

For the PWM inverter to work, whatever the output of the generator, it must be converted (any phase, any frequency, or even DC) to high voltage DC. This can be done independantly of the line frequency or phase.

How to set up a wind power system in the home?

Hi yahoo answers tell me the procedure for setting up the power system in the home..

admin answers:

Electricity can be generated by building Windmills which rotate when there is wind blowing and generate electricity through a generator.Nowadays, the Technology is so improved that we can build our own Solar Panels or Wind Power Generators at home with materials available in our local hardware stores to generate electricity. This way we can eliminate or reduce our Electricity bill.
