Monocrystalline and polycrystalline silicon solar panels

1.What is solar panel?

The assembly which is composed of a number of solar cells assembled in a board according to a certain way.Currently, crystalline silicon materials (including polysilicon and monocrystalline silicon) are the most important photovoltaic materials.

The demand for polysilicon comes mainly from semiconductors and solar cells.According to the different purity requirements,divided into electronic and solar level.Among them,55% for electronic grade polysilicon,solar grade polysilicon accounted for 45%

2.Classification of solar panel

a.Monocrystalline silicon solar panels

Photovoltaic conversion efficiency of monocrystalline silicon solar panels is about 15%, the highest up to 24%, which is the highest photoelectric conversion efficiency of all types of solar panels, but the production cost is so great that it can not yet be a large number of widespread and widespread Use. As the single crystal silicon glass and waterproof resin are generally used for packaging, so its ruggedness, the service life of up to 15 years, up to 25 years.

b.Polycrystalline solar panels

The production process of polycrystalline silicon solar panel is similar with that of monocrystalline silicon solar panel, but the photoelectric conversion efficiency of polycrystalline silicon solar panel will be reduced a lot, its photoelectric conversion efficiency is about 12% (July 1, 2004 Japan Sharp listed efficiency is 14.8% The world's most efficient polysilicon solar panels). Speaking from the production costs, monocrystalline silicon solar panels to be cheaper, easier to manufacture materials, saving power consumption, the total cost of production is lower, so a lot of development. In addition, the service life of polycrystalline silicon solar panels is also shorter than monocrystalline solar panels. In terms of cost performance, monocrystalline silicon solar panels also slightly better.

3.Application of solar panel

A.the user solar power

(1) Small power 10-100W range, for remote areas without electricity such as plateau, islands, pastoral areas, border posts and other military and civilian life of electricity, such as lighting, television, tape recorders, etc .;

(2) 3-5KW home roof grid power generation system;

(3) Photovoltaic pumps: to solve the deep water wells without electricity, irrigation.

B.the traffic area

Such as beacon lights, traffic / railway lights, traffic warning / sign lights, street lights, high-altitude obstruction lights, highway / railway wireless telephone booths, unattended roadside power supply and so on.

C.communications / communications

Solar unattended microwave relay stations, fiber optic cable maintenance stations, radio / communications / paging power supply system; rural carrier phone photovoltaic systems, small communicators, soldiers GPS power supply.

D.oil, marine, meteorological areas

Oil pipeline and reservoir gate cathodic protection solar power system, oil rig life and emergency power supply, marine testing equipment, meteorological / hydrological observation equipment.

E. home lighting power supply

Such as solar garden lights, street lamps, lanterns, camping lights, mountain lights, fishing lights, black lights, taped lights, energy-saving lamps.

F.photovoltaic power station

10KW-50MW independent photovoltaic power plant, scenery (Chai) complementary power station, a variety of large parking lot charging station.

G.solar buildings

The combination of solar power and building materials, making the future of large buildings to achieve self-sufficiency of power is a major development direction in the future.

H.other areas include

(1) Matching with car: solar car / electric car, battery charging equipment, car air conditioner, ventilation fan, cold drink box, etc.

(2) solar power hydrogen fuel cell regeneration system;

(3) sea water desalination equipment power supply;

(4) satellites, spacecraft, space solar power stations and so on.
