PORTABLE SOLAR ENERGY POWER STATIONS
Many families have already started using solar energy to power their homes. Portable solar energy power stations have many practical uses. Today there actually are portable solar energy power stations. Most portable solar power units use photovoltaic panels (PV panels). These portable solar energy stations generate energy from sunlight.
Advantages of using solar collectors
The major advantage of solar collectors - simplicity and relative cheapness of manufacture, ruggedness in operation.
The only important point - please be aware that on a hot sunny day with no parsing water can overheat above the boiling point, so the design must take appropriate precautions.
Other, no less important advantage, is that the collector is able to capture and convert into heat more than 90% has got to him sunlight. Even with light cloud, its efficiency exceeds the efficiency of other types of batteries.

Residential Solar Panels
Solar panels - Power the Future
Solar panel - is characterized as a source of electric current through the photovoltaic cells. The advantage of solar panels due to the lack of moving parts, their high reliability and stability.
On the market solar cells can be divided into several classes:
- Low-power solar panels used to charge cell phones, PDA and other similar electronics. They are characterized by small area of the photographic plates and the relatively high cost.
Parabolic Solar Cooker
Parabolic solar cookers are a simple to use. There are several models for parabolic solar cookers. Parabolic solar cookers are very efficient. However conventional parabolic cookers need frequent adjustment to track the sun.
Solar Pool Covers
Anybody that owns an out of doors swimming pool will definitely wish to keep care of it. The good way to prevent something from getting into the water can be to use a pool cover.
Solar pool covers can help keep your pool clean, also help reduce the size of a solar pool heating system, which can save you money.
Advantages of using Solar pool covers
Solar pool covers are designed to absorb the sunlight. One of the main advantages of coatings is that they prevent heat loss. Evaporation is minimized. Thus, pool covers not only help maintain a comfortable water temperature, but also reduce the cost of heating water in the basin.

Solar panels
Modules are implemented in a constructive manner as monolithic laminate welded single-crystal elements.
- Frame solar cell is designed as a panel, enclosed in a frame made of aluminum profiles. Panel represents a photovoltaic generator, consisting of laminated glass panels c her elements. For the housing unit attached diode unit, under the cover of which placed electrical contacts, designed to connect the module.
- No frame modules are laminate on aluminum, glass, and - without the substrate. Solar cells are located between two layers of laminating film EVA. The front side is protected by an optically transparent film such as PET,

Southampton airport gets solar-powered runway lights
Solar-powered lighting has been installed alongside Southampton Airport's runway.
Nick-named "Wig Wags" the flashing lights cost £25,000 in total and are used at junctions between the runway and taxiways.
Southampton is the first UK airport to install the lights which are also used by the US Air Force in Afghanistan.
An airport spokesperson said: "We've been able to minimise the environmental footprint and maintenance costs."
Solar energy
The five units, supplied by Systems Interface Ltd in Surrey, use solar panels to convert sunlight into electricity and ensure the lights operate 24 hours a day.
Their batteries can store enough energy to permanently operate the lights for up to 120 days without any solar charging.
The lights have also been installed in areas of the airport where there is no access to power supplies, saving the £170,000 cost of laying cables.
They were trialled during last winter as replacements for the conventional lighting systems.
Mark Gibb, director of airside operations admitted: "It's a drop in the ocean, but nonetheless it is part of our overall commitment to, wherever possible, identify possibilities to reduce carbon emissions.
