Solar Energy
SOLAR ENERGY PV
The photoelectric effect refers to the emission, or ejection, of electrons from the surface of a metal in response to light. It is the basic physical process in which a solar electric or photovoltaic (PV) cell converts sunlight to electricity. Sunlight is made up of photons, or particles of solar energy.
Using 4 hours of full sun, gives you this equation: 250 watts x 4 hours. That's 1 kWh (1,000 watts) in a day per 250-watt panel. If you multiply 1kWh per panel by 30 days in a month, you'll find that each 250 watt rated panel will produce about 30 kWh in an average month.
So, a 2,000 square foot home would be allowed a solar array of 4,000 watts. Depending on the type of panel that you choose, a system of this size would be anywhere from 12-18 solar panels. Keep in mind, this formula to estimate consumption varies depending on who provides your electricity.
SOLAR ENERGY MODULE
A photovoltaic (PV) module is a packaged, connected assembly of typically 6x10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.
Solar PV modules made from polycrystalline silicon, as well as new generations of thin-film solar PV technology, are giving residential, commercial, industrial, and utility clients a variety of options to fulfil their solar energy production requirements.
SOLAR PANEL
Due to their lower silicon purity, polycrystalline solar panels are not quite as efficient as monocrystalline solar panels. Lower space-efficiency. You generally need to cover a larger surface to output the same electrical power as you would with a solar panel made of monocrystalline silicon.
Monocrystalline solar panels are slightly more expensive but also slightly more space-efficient. If you had one polycrystalline and one monocrystalline solar panel, both rated at 220 watts, they would generate the same amount of electricity, but the one made of monocrystalline silicon would take up less space.
Concentrating Solar Power Plant
CONCENTRATING SOLAR POWER (CSP) PLANT
Concentrated solar power (also called concentrating solar power, concentrated solar thermal, and CSP) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area.
Concentrating Solar Power (CSP) Technologies. ... CSP technology utilises focused sunlight. CSP plants generate electric power by using mirrors to concentrate (focus) the sun's energy and convert it into high-temperature heat. That heat is then channelled through a conventional generator.
Concentrating solar power (CSP) plants use mirrors to concentrate the energy from the sun to drive traditional steam turbines or engines that create electricity. The thermal energy concentrated in a CSP plant can be stored and used to produce electricity when it is needed, day or night.
PARABOLIC TRUGH SYSTEM
optics,Parabolic trough concentrators have a simple geometry, but their concentration is about 1/3 of the theoretical maximum for the same acceptance angle, that is, for the same overall tolerances of the system to all kinds of errors, including those referenced above. The theoretical maximum is better achieved with more elaborate concentrators based on primary-secondary designs using non-imaging optics which may nearly double the concentration of conventional parabolic troughs and are used to improve practical designs such as those with fixed receivers.
PTS
A parabolic trough solar (PTS) is made of some solar collector modules (SCM) fixed together to move as one solar collector assembly (SCA). A SCM could have a length of up to 15 metres (49 feet) or more. About a dozen or more SCM make each SCA up to 200 metres (660 feet) long. Each SCA is an independently-tracking parabolic trough.
A SCM may be made as a single-piece parabolic mirror or assembled with some smaller mirrors in parallel rows. Smaller modular mirrors require smaller machines to build the mirror, reducing cost. Costs are also reduced in the event of a need to replace a damaged mirror. Such damage may occur due to being hit by an object during bad weather.
