Question by peter out: In a wind turbine, what is the ratio of the input wind speed (to the turbine) to the output windspeed? If we had 2 wind turbines one directly ahead of the other, would the wind exitting from turbine 1 produce the same power in turbine 2? —————————————— Answer by rsdudmDepends on

Question by elrodvoss: What Solar Panel Efficiency would replace Coal? A friend sent me an article that a company called Fraunhofer has produced solar panels that can achieve 41.1% efficiency. Now taking into account the fact that solar do sent work during storms or night and greatly reduced during winters, what % do you think

This is just one of many sites on the web.

Just put in “home solar panels” in a websearch and you’ll get more.
By the way, solar electric power is not cheap. If it were, everyone would have them including the electric company. The time it takes to get your money back from one of these systems can be 10 years or more. Energy conservation is a better way to go.

If you don’t live in a large city, try your county extension agency for references.
Second, other response is correct. Solar recovery costs take a while, between 5 to 10 years depending on quality of panels bought and size of project.
Finally, why not talk to your utility company? Most electric companies now have an energy program that will pay you for excess electricity if you use less than you produce, whether solar or wind. What happens is when you produce more than you use, the meter actually reverses, thus lowering your costs, as the power reverts back to the electric company for use elsewhere. They would be glad to assist you with recommendations and to talk about recovery of costs.
Wind power is a whole different prospect. Aside from its initial high cost, you could run into issues with neighbors who aren’t from the Netherlands and don’t appreciate the aesthetics of a 30′ tall tower near their homes. If you don’t have neighbors, remember that conversion from wind power to electricity involves a whole lot of conversion systems and they take space.
For both, you also have to think about “switching” for when you don’t get enough power from your unit and require it from your power company. I think there is a unit that measures demand and adds from company when you don’t produce enough, and that adds to the costs as well.
Good luck. Wish more people wanted and were able to go greener.

You may want to hold off on buying a solar system for a while….there’s a new technology called thin-cell solar (cadmium telluride and others) that’s being developed which could cut the costs in half to a third of what silicon based solar produces per watt produced. Very exciting possibilities.
