First; we can build rapidly solar energy production facilities suitable to meet the energy needs of rural and urban areas.

Second is; models with a solar greenhouse is versatile and innovative aspects. We are also proud to support academic, technological, agricultural, tourism and education fields, provided that they are requested and discussed in detail.

A study by NREL on solar power plants in the United States found a wide range of total land use requirements across the different technologies. The average total land footprint of solar generation capacity was estimated at 8. The configuration of utility- scale plants also makes it difficult to share this land for other uses such as agriculture. It is also important to note that utility scale solar infrastructure theoretically have lifetimes of years.

Concerns have also been raised over the effects of utility-scale generation on soil quality. Research in China has shown that land use change clearing of vegetation, digging of foundations, construction traffic for solar thermal construction has led to soil erosion in near environment, particularly in regions with sandy soils and a dry climate. Results also showed that solar thermal installations lowered soil temperatures by 0. The negative impacts of utility-scale solar can be minimized, somehow, by siting plants in brownfield locations.

Floating PV systems Photovoltaic systems have been successfully deployed on land and in space for many years, so it was only a matter of time before water-based PV systems emerged on larger scales.

Over the past five years, a myriad of floating systems has evolved in varying degrees for use in ponds, reservoirs, canals, rivers and oceans. Nowadays, bodies of water aren't necessarily something to build around they're something to build on.

They sport not just landfills and man-made beaches but also, in a nascent global trend, massive solar power plants. Clean energy companies are turning to lakes, wetlands, ponds, and canals as building grounds for sunlight-slurping photovoltaic panels. So far, floating solar structures have been announced in, among other countries, China, United Kingdom, Australia, India, and Italy.

The biggest floating plant, in terms of output, will soon be placed atop the reservoir of Japan's Yamakura Dam in Chiba prefecture, just east of Tokyo. When completed in March , it will cover , square meters, hold 50, photovoltaic solar panels, and power nearly 5, households.

It will also offset nearly 8, tons of carbon dioxide emissions annually. Since the EPA estimates a typical car releases 4. This is a photovoltaic greenhouse with a roof structure with horizontal beams and small flat pitches. Structure consisting of IPE beam or rectangular tube columns and lattice girders which allows any type of internal and external system to be installed including gutters and hanging pots. Figured glass or transparent float glass, normal or tempered, can be used.

It has large ridge and sidewall vents for ventilation. The type of vent on the roof with hinges on the ridges provides excellent ventilation and prevents the vents forming shadows on the solar panels. Anti-corrosion protection with hot-dip galvanization.

This is the most classic greenhouse, with two flat sides, known internationally as a "wide span" greenhouse. It is traditionally the most popular greenhouse in Italy and offers good light, ventilation and versatility.

This is a photovoltaic greenhouse with a roof structure with two very wide flat pitches "Wide Span". A very solid, versatile structure consisting of IPE beam or rectangular tube columns and lattice girders which allows any type of internal and external system to be installed including gutters and hanging pots.

It has one ridge flap and sidewall vents for ventilation. This characteristic makes greenhouses suitable for use in multi-aisle greenhouses. Horticulture in this greenhouse is very similar to that of a normal greenhouse without solar panels since there is constant movement during the day time of areas of shadow on the crops.

No notes for slide. Presentation on solar cell 1. An atom of sili-con has 14 electrons, arranged in three different shells.

The outer shell has 4 electrons. Therefore a silicon atom will always look for ways to fill up its last shell, and to do this, it will share electrons with four nearby atoms. Now we use phosphorus with 5 electrons in its outer shell.

Therefore when it combines with silicon, one electron remains free. These are called free carriers, which move randomly around the crystalline lattice looking for holes to fall into and carrying an electrical current.

However, there are so few, that they arent very useful. As a result, we have a lot more free carriers than we would have in pure silicon to become N-type silicon. Each photon with enough energy will normally free exactly one electron, resulting in a free hole as well.

If this happens close enough to the electric field, this causes disruption of electrical neutrality, and if we provide an external current path, electrons will flow through the P side to unite with holes that the electric field sent there, doing work for us along the way. The electron flow provides the current, and the cells electric field causes a 9 Discrete Cell technology.

Integrated Thin Film technology. Multi crystalline Silicon technology.

Almost every energy source creates some sort of noise, but that is not the case with solar panels and cells. The provision of electricity to rural areas derives important social and economic benefits to remote communities throughout the world like power supply to remote houses, electrification of the health care facilities, irrigation and water supply and treatment.

Many lighthouses are now powered by solar cells.

These modules often have a sheet of glass on the front sun up side, allowing light to pass while protecting the semiconductor wafers from climate conditions. Solar cells are also usually connected in series in modules, creating an additive voltage.
