Title:
Solar Photovoltaic (PV) on Free-fall lifeboat Alternatives:
Solar thermal:
The alternative is solar thermal, it’s a technology that uses the power of the sun to heat water.
It is a collection of flat plate panels or evacuated tube panels are installed on the roof of an object. In the panel there is material called non-toxic freeze proof solar fluid is heated by the sun then the operation continue by pumping the material inside the hot water tank through a pipe coiling, which increase the heat of water in the tank. Then a hot water will be available for using. After that the process will act as a backward operation by pumping the solar fluid to the panel, where the sun once again heats it.
In fact, the system is able to afford the object with hot water for about 70-80%. However during the winter that amount of daylight hours will drop slightly.
Furthermore, the size of the solar thermal flat plate panels is compact line solar thermal collectors with black anodized frame. Every panel is 2039mm x 1139mm x 80mm, with an absorber surface of 2.15 m2, and a gross area of 2.32 m2.
Wind Turbines:
Alternatively, Wind turbines harness the wind’s energy to create electricity. The wind turns the blades and during that rotation its run the turbine of the generator, which will result an electrical current. Besides, wind turbines can supply electricity and that electricity can be used as a power for electric heating system such as night storage heaters. As well the size of a wind turbine is depend on its potential output. In that case the systems can handle a range from hundred Watts to above seven Megawatts (MW).
In contrast, there many disadvantage of that system for instance wind turbine will require some maintenance due to its small-scale and that maintenance to ensure continues of the performance and expectancy of life span. However various types of systems require an annual maintenance check-up, which is why they are designed with a tilt up tower to enable this. In comparison with the other systems will require less servicing.
