Solar cells are made of two layers (a positive side and a negative side), when they are placed on top of each other they create an electric field, the same way a magnet does.
A solar panel is an array of solar cells that use photovoltaic technology to convert direct sunlight into direct current (DC) electricity.
Generator systems do not depend on sunlight. They do, however, depend on fuel. If storms or some other disaster hinders one from replenishing the fuel supply, generators also become useless.
It goes without saying that the ability to perform well of a solar power generator is contingent upon the quality of the design, its size and what you utilize it for.
Generally it's worth investigating the economic viability of installing a solar hot water system if you have an electric water heater with utility rates of at least 5 cents per kilowatt hour and have tax credits or rebates available. (It may even be worth changing out a gas-powered water heater if your costs are at least $8/million BTU).
However the biggest issue with solar power is it's reliability. Ideally you need a location that gets plenty of sun throughout the year.
Solar panels are cheap to use because there are no fuel expenses like in electricity generators.
The cost of solar power versus generator is much less over the long term.
In the past solar power has suffered from an image problem which it has just recently recovered from.
Even the tiny percentage of sunlight that touches the earth is plenty to meet the energy and power needs of the entire human population more than 8,500 times over.
A wide array of wind power generation tools is available for this purpose. These tools are termed home wind power kits. 17th October, 2009
Nearly all countries around the globe have finally come to terms with the fact that changes in power usage customs will have to be made in the future. 1st October, 2009
Imagine your neighbors told you they were going to produce their own home turbine wind power? Would you be shocked? Well, very soon that may be the norm. 15th October, 2009
This article presents some of the major offshore wind projects either in commercial production or in development stages. 19th October, 2009
Wind power generation may be on a very big scale, as with most commercial projects, or it may be on a very small scale which is the case with home owner wind turbines. 11th October, 2009
