Amorphous silicon solar cell 非晶硅太阳能电池
Thin-film solar cells are usually produced by evaporating several semi-conductor films onto a so-called "substrate"
Unit indicating the strength of electric current
Assembling system 集成系统
System to install solar modules on roofs, façades or in the field.
Azimuth angle 方位角
Describes the deviation from the South towards East-western direction
Building-integrated PV (BIPV)
Used to describe a structure where PV replaces conventional materials and is integrated into the building. Typically, a photovoltaic array is incorporated into the roof or walls of a building. Roof tiles with integrated PV cells can now be purchased. Arrays can also be retrofitted into existing buildings; in this case they are usually fitted on top of the existing roof structure. Alternatively, an array can be located separately from the building but connected by cable to supply power for the building.
By-pass diode 旁路二极管
Conducts the electricity automatically past a module in case it is shadowed in one series. This is supposed to prevent any destruction due to overheating.
A system of conductors that convey electricity.
CdTe solar cell碲化镉太阳能电池
Thin-film solar cell made of very thin CdTe semi-conductor films (< 3 microns)
CIS solar cell
Thin-film solar cell made of several films of differently doped copper-indium-diselenide
Circuit breaker 断路开关
A safety device that shuts off power when it senses too much current.
Combiner box 和路箱
Where the electrical wiring from the PV modules is joined together in parallel to combine electrical currents.
A material that is used to convey electricity, i.e. wires.
Conversion efficiency 转换效率
The percentage of electricity that is created by a solar cell as compared to the amount of energy needed to generate that electricity.
The flow of electricity between two points. Measured in amps.
Energetic amortization period 能量偿还期
Period of time a photovoltaic system requires to produce the energy required for production.
The ratio of output energy to input energy.
Electrical grid 电网
A large distribution network that delivers electricity over a wide area.
A conductor used to lead current into or out of a nonmetallic part of a circuit.
Usable power. Measured in kWh.
Energy audit 能量审核
A process that determines how much energy you use in your house or apartment.
Energy yield 能量输出
Electric energy indicated in kWh yielded by a photovoltaic system
Equipment to control the grid with attributed all-pole control element in series. The ENS includes a redundant voltage and frequency control of the electricity grid and evaluates any leaps ascertained in the grid impedance. If the set limits are exceeded, the ENS will switch off the inverter. When the line voltage is re-established, the inverter will restart operation automatically.
European efficiency rate
Weighted efficiency rate is calculated by weighting different partial load efficiency rates and the full-load efficiency rate in line with the frequency of their appearance.
