An electricity expert, Werner von Siemens, asserted the discovery was ‘scientifically of the most far reaching importance’. The selenium cells were not efficient, though it was showed that light, without heat or moving parts, may be altered into electricity. In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, discovered the silicon photovoltaic power cell.

The NY Times claimed this discovery was ‘the start of a new time, leading at last to the realization of using the just about limitless energy of the sun for the uses of civilization. ‘ The year is 1956, and the first photovoltaic power cells are available commercially. The price tag however is a long way from the reach of everyday folk. At $300 for an one watt solar power cell, the cost was miles beyond anyone’s means. 1956 started showing us the initial solar power cells utilized in toys and radios. These novelty items were the first item to have solar cells available to consumers.

In the early 1970′s a strategy to lower to cost of photovoltaic power cells was discovered. This brought the price down from $100 per watt to about $20 per watt. This analysis was fronted by Exxon. Most off-shore oil rigs exploited the photovoltaic power cells to power the fading lights on top of the rigs. They started showing up on railroad crossings, in remote places to power homes, Australia used solar power cells in their microwave towers to grow their telecommunication capacities. You will see solar powered vehicles. With the cost of photovoltaic power cells well inside everybody’s budget, solar power hasn’t looked so alluring. Lately advanced technology has given us screen made public photovoltaic cells, and a solar fabric that can be made use of to side a home, even solar shingles that install on our roofs.

World markets have opened up and solar cell makers are now playing a major role in the solar power industry.

You can get chargers of varying prices ranging from $100 all the way up to 6 or 7 thousand dollars. Of course you get what you pay for, with the cheaper models capable of charging smaller electronic devices such as cell phones and laptops, while larger solar chargers can power a few key electric appliances like your refrigerator or freezer, or perhaps a TV in case there are particular sports events that you don’t want to miss.

If you have a boat, marine applications can be a little trickier as you will need to make sure that you get a charger that is compatible with the kind of marine battery that you have. There are several considerations before you purchase a marine battery charger whether you have a deep-cycle or starting marine battery. If you need a continuous charge to be supplied to your batteries to ensure nonstop operation, a linear charger can monitor your energy levels and automatically charge whenever it falls below 90%.

However they would need to be placed in a waterproof space wherever it is accommodated. Electronic chargers do not have the same problem as they are already waterproofed. However they are more ideal for casual or seasonal boating enthusiasts since they do not monitor a battery’s energy levels. There are portable and on-board varieties that you can choose from, and it is recommended to go for an on-board charger if you have the space on your boat to accommodate it.

The Dual Pro series of chargers is among the best that you can get if you are looking for a high quality charger for marine applications, setting the standard for many other marine chargers that are also on the market. Dual Pro Chargers feature several technologies to ensure smooth operation such as protection from reverse polarization, short-circuiting, and the ability to charge different types of batteries no matter what their starting points or how large the actual batteries are.

They also produce battery chargers to fit different performance profiles. So if you are looking to maintain a single on-board battery for casual boating purposes or perhaps need to charge several batteries for multiple applications, then there is a Dual Pro charger for you.
