2:04 AM Solar Power Systems 1 Comment

Solar power systems have experienced a surge in popularity because of the rising cost of conventional energy sources. By, adding a solar energy system to your home, you can recoup your investment over a few years and continue to save money on utility bills for the life of your system. The lion's share of the electric utility expense is used in heating the house in the winter and cooling the house during summer months. If you live in the northern climates with intensely cold winters, heating...

How does Solar power Works Without the Sun?

1:01 AM How does Solar power Works Without the Sun? 1 Comment

Alternative power sources such as solar and wind are being developed because they reduce pollution and green-house gas emissions while increasing the United State's energy independence. A major problem with solar energy is that it is only available when the sun is shining. Therefore, methods to transform and either store the energy until needed or combine it with energy from other sources have been developed. Thermal Energy: ...

How Does Solar Energy Transform Into Electricity?

12:57 AM How Does Solar Energy Transform Into Electricity? 1 Comment

Technology is available to take solar energy and convert it into electricity in order to power space ships and satellites and hand-held devices and provide electrical energy to homes. There are two primary methods for creating electricity from solar power. Photovoltaic technology coverts solar energy into electricity, and solar thermal energy generates electricity through a heating process. Photovoltaic: Photovoltaic cells are made from a material...

Mecasolar trackers adapted for use at 600 kW CPV plant in Italy

12:41 AM Mecasolar trackers adapted for use at 600 kW CPV plant in Italy 1 Comment

On January 11th, 2012 Mecasolar (Fustiñana, Spain) reported that it has delivered 55 tracking systems to a 600 kW concentrating solar photovoltaic (CPV) plant in Italy. These trackers will be retrofitted to the plant, which is currently operating. Each tracker will support 48 230 watt CPV modules, for a total of 11 kW per tracker. The CPV modules use a 5x concentration design, and Mecasolar states that this project shows that its trackers can be easily adapted to other types of low-concentration...

New Plastic Solar Design Promises Efficient Power

11:00 PM New Plastic Solar Design Promises Efficient Power 1 Comment

In a quiet research laboratory here, an Inventor is developing solar power devices designed to operate four or five times more efficiently than the beat photovoltaic cells now in use, and at a small fraction of the cost. Alvin M. Marks, an inventor who, holds patents for a 3-D movie process and polarized film for sunglasses, is working with the Westinghouse Electric Corporation to build prototypes of the solar power devices. He received one patent for the devices earlier this year and another...

Solar Panel Saves Electricity

12:10 PM Solar Panel Saves Electricity 1 Comment

Saving electricity usage in your home is really the first big step in the process of going solar. In most cases an average solar power system will not supply you with 100% of your energy needs, so to make the whole thing more cost effective it is vitally important to find as many ways as you can to make your home as energy efficient as possible. Whether you are looking for ways to make sure that your household is living in a more Eco-friendly manner or you are just searching for ways to...

Solar Planes

11:51 AM No Comments

A solar plane's flight starts with checks. Check the battery -- it should be charged. Check the ground winds. They shouldn't exceed about 10 miles per hour (16 kilometers per hour), or else the plane could crash on the runway. Check for turbulence in the air because the plane will have to ascend through the turbulent layers. Billows in the clouds are a bad sign. "Wind is your enemy," says Del Frate. Morning is best for takeoff, when the sun is overhead and there are ample hours...

Remember the race I was talking about last few weeks about solar cars?Well it has come to the finish line and it is in Garden City, Kansas. Imagine going around in a never ending race without going for a gasoline station to feed your mobile up. That is precisely the point they are teaching all of us here that cars can be charged by the use of solar energy. Some critics said that these cars will not reach the pit stop and that the cars will just die because it just depends on the rays of...

NASA Solves Solar Energy's Dust Problem

1:53 AM 1 Comment

Here's a problem for solar energy you may not have thought about: dust. With many of the best sites for solar panels in deserts, the accumulation of dust on top of photovoltaic surfaces can block sunlight and reduce their efficiency by up to 80 percent. And cleaning a huge field of solar panels by hand is a big task. Interestingly, NASA faced a similar problem with the Mars rovers, which had to be able to clean their own panels with no direct human help in a dusty environment. And the NASA...
