1. Power system part
(1) Photovoltaic plate
PV plate (solar panels and solar panels,
solar PV module), absorb the light energy and transfer the light energy into electrical
energy, PV board commonly used materials have monocrystalline silicon,
polycrystalline silicon and amorphous silicon, including monocrystalline silicon conversion
efficiency is14 ~ 20%, polycrystalline silicon conversion efficiency is about 13%,
amorphous silicon is 8 ~ 10%. This renewable energy lab equipment is used for technical colleges which set up Photovoltaic subject project.
（2）Store electric equipment
At present off-grid type generating system
store electric equipment in order to avoid
maintenance cell is given priority to, the
battery can stock up power that produced by the PV plate.
（3）Charging and output control controller
Controller is used to control the whole
system stable work safely.
(4）Other mechanical
equipment
2. Power generation system main cost structure and influence factors
（1）Photovoltaic plate
At present the solar energy industry spread to open completely, one of the main
reasons is too high Photovoltaic plate prices, influent the system PV plate prices, in addition to control from PV plate unit price, but the most important is to control the use quantity of PV plate, its influence factors are the following:
A、Generated power：In a certain sense, the greater the generation power, the more PV plate usage, the higher the cost is, proper control generating power can properly
control the cost.
B、Photovoltaic plate local weather conditions: Obviously, in the same area, the same piece of PV plate, it generates electricity in sunny day than cloudy day’s, it can explain the different areas have different PV plate usage.
C、PV plate local latitude, in the same day, the sun exposure is different to different
latitude, this will cause the same piece of PV plate on the same day produce different
electric quantity in different latitude.
D、PV plate use environment, for example, PV plate used in the top of the hill, one
day down, do not have any barrier things keep out exposure sunshine in PV board,
power generation capacity must be good, if use PV plate at the foot of the mountain,
the day down, more or less will be screened things keep out exposure sunshine in PV
board, so the surrounding environment that PV plate use whether have barrier things exist, to a certain extent affect the PV power generation capacity.
（2）Energy storage equipment
A power system will supply how much power for the user in one day, and this
determines the energy storage equipment capacity, power generation system supply
users the more power consumption every day, the larger energy storage equipment
capacity requirements is, the higher the cost.
The user’s average power consumption size on every day, every day the greater the
user’s power consumption, energy storage equipment price is higher.
3. Technology feature
Verifier
Verifier effectively improve the whole power system storage capacity, plays an
important support role for the whole system key link, effectively improve the system
stability and efficiency, save the cost of PV plate for a complete system, reduce the
system cost. Verifier have intellectual property protection.
PV plate absorb sunlight technology
PV plate can effectively absorb sunlight, and give greater scope to PV power
generation capacity, greatly improving day generating capacity, reduce the cost of PV plate.
4. Clients should provide material
A class
（1）System output max power
（2）Users’ day power consumption, electricity equipment power and the electric
equipment use duration
（3）User local weather climatic conditions (countries)
（1）Users’ all electric equipment and various electric equipment use duration
（2）User local weather climatic conditions
Description: system general design is power generation of a day in enough sunlight,
don't consider power generation of overcast and rainy day , so the system will only
bear electric equipment use of a day, if customers have other requirements moreover
consider.
