I-V curve |
A graph that plots the current versus the voltage from a PV cell as the electrical load (or resistance) is increased from short circuit (no load) to open circuit (maximum voltage). The shape of the curve characterizing cell performance. Three important points on the I-V curve are the open-circuit voltage, short-circuit current, and peak or maximum power (operating) point. |
|
I-V data |
The relationship between current and voltage of a photovoltaic device in the power-producing quadrant, as a set of ordered pairs of current and voltage readings in a table, or as a curve plotted in a suitable coordinate system [ASTM E 1036] |
|
Incandescent light |
An electric lamp which is evacuated or filled with an inert gas and contains a filament (commonly tungsten). The filament emits visible light when heated to extreme temperatures by passage of electric current through it. |
|
Incentive programs |
Incentive program the project is entitled to. |
|
Incident light |
Light that shines on to the surface of a PV cell or module. |
|
Independent power system |
A power generation system that is independent of the mains grid. |
|
Insolation |
The amount of sunlight reaching an area, usually expressed in Watt hours per square meter per day. |
|
Install date |
Refers to manufacturing equipment installation timing for a fab or a fab phase. |
|
Installation Phasing |
The phasing of the installation, which might be in a single or multiple years. |
|
Installed Price |
The total dollar PV system installed price. This includes all equipment and installation, but excludes land costs. |
|
Installer |
Markets and customizes PV systems for installation. |
|
Insulation |
A material used to prevent the flow of electricity. Normally used on electrical wires to prevent electric shock. Typical materials used include plastics such as PVC and polypropylene. |
|
Integrator |
Combines PV components into a complete PV system. |
|
Interconnect |
A conductor within a module or other means of connection which provides an electrical interconnection between the solar cells. [UL 1703] |
|
Inverter |
An inverter converts DC power from the PV array/battery to AC power. Used either for stand-alone systems or grid-connected systems. |
|
Irradiance |
The solar power incident on a surface, usually expressed in kilowatts per square meter. Irradiance multiplied by time gives insolation. |
