99% of the solar radiant energy is concentrated in the wavelength of 200
nm to 3000 nm .In the range of 200 nm to 800 nm, ultraviolet and visible light
accounts for about 58% of the total energy of the sun radiation. The infrared
light accounts for about 42% of the total energy of the sun radiation in the
wavelength at 800 nm to 3000 nm. For now, photoelectric material and
thermoelectric materials research has made significant progress.
Solar composite plate dry power technologies is integrated
thermoelectric and pjotoelectric technology at low cost, which can increase
the efficiency of solar power generation over 20% and
greatly reduce the cost at the same time.
energy utilization is only 12-15% in a traditional photovoltaic system. About
80% of the energy is converted into heat energy, which almost all wasted.
Moreover, almost all other transformation of heat energy may produce higher
temperature on the solar panels power generation. The extra higher temperature
makes solar panels power generation efficiency drops, so the heat dissipation
problem become a big problem in the photovoltaic industry development.
Solar-thermal composite wet power generation system can export excess heat
generated by solar radiation transmission perfectly through the super heat
transfer performance of micro heat pipe array.
On the one hand, improve the efficiency of power generation assisted with
semiconductor thermoelectric power generation ;On the other hand ,the heat
through conduction can be recycled to produce hot water again. The total solar
radiation efficiency can reach 70%, 20% of it converted into electricity, 50%
is converted into heat energy.
Compared with the traditional photovoltaic power generation system, the
utilization of solar energy is only 12-15%, Solar panel power generation plate
utilization is much higher and the cost is cheaper, have a larger space.
