Company Profile:
The maximum energy demand or load in a specified time period.
Industry:Energy
A chemical element, metallic in nature, used in making certain kinds of solar cells and semiconductor devices.
Industry:Energy
Amperes produced by a photovoltaic module or array operating at the voltage of the I-V curve that will produce maximum power from the module.
Industry:Energy
Operating point of the I-V (current-voltage) curve for a solar cell or photovoltaic module where the product of the current value times the voltage value is a maximum.
Industry:Energy
see maximum power tracking.
Industry:Energy
The rate of energy transfer equivalent to one ampere under an electrical pressure of one volt. One watt equals 1/746 horsepower, or one joule per second. It is the product of voltage and current (amperage).
Industry:Energy
The equivalent number of hours per day when solar irradiance averages 1,000 w/m2. For example, six peak sun hours means that the energy received during total daylight hours equals the energy that would have been received had the irradiance for six hours been 1,000 w/m2.
Industry:Energy
A crystalline, high-efficiency compound used to make certain types of solar cells and semiconductor material.
Industry:Energy
A unit used to rate the performance of solar cells, modules, or arrays; the maximum nominal output of a photovoltaic device, in watts (Wp) under standardized test conditions, usually 1,000 watts per square meter of sunlight with other conditions, such as temperature specified.
Industry:Energy
The shape of the phase power at a certain frequency and amplitude.
