AC交流电

Alternating current

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"

Ampère 安培

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 int o ex isting buildings; in this case they are usually fitted on top of the ex isting 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. Circuit 电路

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.

Conductor 导体

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.

Current 电流

The flow of electricity between two points. Measured in amps.

DC 直流电

Direct current

Energetic amortization period 能量偿还期

Period of time a photovoltaic system requires to produce the energy required for production.

Efficiency 功率

The ratio of output energy to input energy.

Electrical grid 电网

A large distribution network that delivers electricity over a wide area.

Electrode 电极

A conductor used to lead current into or out of a nonmetallic part of a circuit.

Energy 能量

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

ENS

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.

Facade system 正面系统

Photovoltaic system installed on the facade of a building or an integral part of a facad e.

Feed-in meter 输入计

Measuring instrument for the supply of electric energy into the public power grid (unit in kWh) Mismatching interconnection o f better and worse modules in one string as a consequence of which the worst module of one series determines the electricity.

Field system 野外系统

Photovoltaic system installed in a field

Flat-roof system 平台屋顶系统

Photovoltaic system installed on a flat roof.

Fossil fuels 矿物燃料

Fuels that are formed underground from the remains of dead plants and animals. i.e. oil, natural gas, and coal are fossil fuels.

Global radiation 总辐射

Sum of diffuse, direct and reflected solar radiation onto a horizontal surface.

Greenhouse effect 温室效应

When heat from the sun becomes trapped in the Earth's atmosphere due to certain gases.

Greenhouse gases 温室气体

The gases responsible for trapping heat from the sun within the Earth's atmosphere. i.e. water vapor, carbon diox ide, methane, ozone, chlorofluorocarbons, and nitrogen oxides.

Grid 电网

A distribution network, including towers, poles, and wires that a utility uses to deliver electricity.

Grid-connected PV system 并网光伏系统

When the electricity grid is available but electricity from a clean source (solar) is desired, solar panels can be connected to the grid. Provided that sufficient panels are placed, the appliances in the house/building will then run on solar electricity. A grid-connected solar electricity system basically consists of one or more solar panels, an inverter, cables, the electric load and a support structure to mount the solar panels.
