Hello and welcome to my solar power blog! Here, you can learn a lot about the various aspects of solar power. I will also try to add some new info every now and then, together with my friend Gareth.

The Sun

June 21, 2009

The most important feature of our solar system is the Sun. It is the largest object in it, and contains almost 98% of the total mass of the solar system. The visible outer layer of the Sun is known as the photosphere, and its temperature is 6,000 degrees Celsius. Inside the Sun’s core, the creation of solar energy takes place. The temperature is so high that nuclear reactions take place, which causes four protons or hydrogen nuclei to fuse together, thus forming one alpha particle, or helium nucleus.

Solar pool heating

June 20, 2009

Solar pool heating is one of the many applications of solar based heating. These are not only cost efficient but also helps in reducing green house emissions The system is simple to use and relatively very less expensive. It allows people with this system installed to extend the amount of time in the year that they can swim, thus swimming season is expanded. Read the rest of this entry »

Solar collector

June 19, 2009

A solar collector is basically a device which is used to use the direct energy of the sun to store it in a more usable variety. Such a collector clubbed with a system of a heat transfer circuit and a proper storage system results in helpful commercial devices. Such systems can be used to fulfill various purposes, for domestic purposes these can be used for warming water or for warming swimming pools or for providing energy for a cooling system etc. Read the rest of this entry »

Solar chargers

June 16, 2009

Solar chargers are great, for travelers, and of course, for just about anybody. These portable devices are user-friendly, and take energy from the sun. You need not be harassed with carrying international voltage adapters, because there is really no need for it to be plugged into any electrical outlet. Often people worry a lot thinking what kind of charger will work in what country, but solar chargers are guaranteed to work everywhere there is sun. Read the rest of this entry »

Solar water heater

June 15, 2009

What is a solar water heater? It has a collector, which collects solar energy, and it has an insulated storage tank, which stores hot water. Solar water heaters can be of two main types, depending on the collector system, the first type is the Flat Plate Collectors. In this, the flat plate collectors absorb the solar radiation, they are made up of an insulated outer metallic box, which is covered by a glass sheet on the top. Inside, the blackened metallic absorber sheets have built in channels, or riser tubes, which the function of carrying water. The solar radiation is absorbed by the absorber, and the heat is transferred to the flowing water. Read the rest of this entry »

Photovoltaics deals with the conversion of solar energy directly to electricity, and is related to the technology and the research it involves. Because renewable sources of energy are much in demand now, solar photovoltaic energy is increasing in importance, and many options have been explored, in recent years. In fact, every two years, photovoltaic energy has been doubling, the increase is by almost 48-49% each year, since 2002, and thus, it is the world’s fastest growing energy technology.

Firstly, let’s understand what a solar cell is. Simply put, it is a device that converts sunlight into electricity, through the photovoltaic effect. Sometimes, lots of solar cells are assembled to make solar modules, solar panels, or even photovoltaic arrays. Those solar cells that can generate electricity with a higher efficiency than the usual or conventional solar cells are called high efficiency solar cells. These are more efficient because of their electrical output per incident energy, that is, watt/watt. Constant research is going on, to increase the efficiency of solar cells.
