Were invented long time ago as you may remember in 1970’s there was the first electronic calculator which was powered by solar cells. It was a very amazing invention on that time as people had no idea how the tiny cells can produce electricity plus the fact they would last for a very long time. There was a stagnant period regarding solar cells usage as by then electronic calculator was the only daily item that could be powered that way. Indeed a larger scale of solar cells project is keep going on until to date. The only thing is the production cost was too expensive in earlier year while energy supply was not a big issue.

Today we have to face the fact that natural energy sources are running out until the critical limit. As a main part of the eco system then every basic elements are heavily disturbed as well i.e. water sources and air. are the only answer to substitute the conventional electric energy generators which are large water and gas turbines. Whether we like it or not the fact is we cannot go on anymore to drill new deep wells which are hundred metres deep each to pump out the raw oil which later on being converted into electricity power.
Modern solar cells are completely different from the earlier versions you have seen before. They are now very compact in dimensions as well as can produce more electricity because of higher efficiency and power factor. Advanced semi conductor technologies enable these fantastic features so you want to start thinking about reducing your electricity bill by start using solar cells at your house. If you have warehouse or similar premises which need lighting all night long then you may consider the solar cells usage.
The only thing you need to do next is to find out the suitable new generation of LED light bulbs to suit your preference. As you know lighting is a matter of color rendering so as long as you find the right color render then you should not feel too much eye sight difference at the first days of using the new type of LED light bulbs. You can rely on the lux per square feet they produce as then you will not lose any focus on objects you used to see. Solar cells now are being offered in ready for use kits which you can handle by yourself to install as basically it will requires engineering skill that you have with you.
