PV Gap

Monica Said:

The Applicatiom of solar energy in a location & techonolgy,systems,efficiency & the cost that are involve.?

We Answered:

using solar energy is good but can be expensive, what is your question about it?

Scott Said:

Are solar and wind energy systems suitable only when the sun is shining and the wind blowing?

We Answered:

There are some options. For either, you can tie them to the grid, and hopefully one area will have a surplus when another area is in the doldrums. Electricity is already transferred long distances, so this is not new, but load balancing is an issue, and there are problems with new power sources being added to the grid.
For solar, first maximum energy load is during the day, particularly on hot days when the A/C is needed, so solar plants can take the place of natural gas "peaker" plants, used to help with a peak load. Second, if you have solar thermal (as opposed to solar photovoltaic), you can heat up a mass which retains its heat, and then use that heat later. This could work for several days of heavy clouds, but overall power production would eventually be reduced. Photovoltaics work rather well in light overcast situations, it doesn't need a clear blue sky.

Ellen Said:

How would convert solar energy to electrical energy?

We Answered:

Solar energy panels can capture the suns energy, to transfer to electricity hook the panel to a 12 volt voltage regulator and then to a automotive 12 volt battery.
To use the electricity hook up a voltage regulator to the battery then hook a toggle switch to the voltage regulator positive wire feed, on the other end of the regulator hook up a 12 volt appliance or light bulb, grounded of course.
