Making Steam With Sunlight And Solar Panels

Solar concentrators work by focusing the sun s rays on a water pipe to generate steam.

Making steam with sunlight and solar panels.

The major drawback of solar power is that it entirely depends on the sunlight and favorable weather conditions. After that point 86 percent thermal energy or heat is created. In most cases the sun s energy is converted into electricity in one of two ways. Or using solar thermal turbines which use the sun s heat to generate steam which then spins a turbine to produce electricity.

Steam from the solar steam generator can drive an electrical generator. Steam is important for desalination hygiene systems and sterilization says ghasemi who led the development of the structure. This mod adjusts the power output of solar panels to reflect this reality. However researchers from the institute for research in electronics and applied physics ireap have developed a special kind of photovoltaic cell that could generate power even without sunlight.

Optically a solar power tower is the same as a circular fresnel reflector. Large solar panel 400kw in 0 air density. Solar panels should now be far more effective in space making them more like windmills are on planets.

The receiver contains a heat transfer fluid which can consist of water steam or molten salt. Mother earth news staff previous articles from mother earth news showed you how to build a low cost solar furnace frame and. The sun is significantly brighter in space as much of the solar radiation is blocked by earth s atmosphere. The way photons interact with solar cells they can only generate electricity from the sun s energy up to a certain point.

One way to improve thermodynamic efficiency is to construct multi junction or tandem solar cells. A heat transfer medium water steam molten salt or air in the receiver absorbs the thermal energy and transfers it into the steam cycle to generate superheated steam for the turbine. The advantage over the parabolic trough or fresnel collector concept is that the sunlight on the central receiver is focused to a smaller area and the heat transfer medium does not have to be piped around the large solar field. A solar power tower consists of an array of dual axis tracking reflectors that concentrate sunlight on a central receiver atop a tower.

Using photovoltaic cells which turn the sun s light into electricity using a semiconductor material that absorbs photons and releases electrons.
