Float charge is the voltage required to counteract the self-discharge of the battery at a certain temperature. A float charger will charge a battery at a similar rate as a battery self-discharges, thus maintaining a full capacity battery

Fixed Tilt Arrays are arrays of Solar Panels placed at a fixed angle which is usually the optimum tilt. To obtain maximum efficiency from the solar panels they need to be pointed in the direction that captures the most sun.…

The fill factor is the ratio of the actual maximum obtainable power to the product of the open circuit voltage and short circuit current. This is a key parameter in evaluating performance. Fill Factor is a measure of the “squareness”…

Facade Installation is a PV system that is mounted on a building facade or permanently integrated into the facade.

EVA(Ethylene Vinyl Acetate) is an encapsulant for solar Cells/ Modules. It is a copolymer film which acts as an essential sealant of photovoltaic solar modules for ensuring the reliability and performance. Encapsulant sheets play an important role in preventing water…

The time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length (about 22 September and 20 March). Equinoxes and Solstices are useful for learning Solar Path and Seasons.

In batteries, equalization or an equalizing charge is forced overcharge to remove sulfation that may have formed during low-charge conditions. Battery manufacturers recommend first measuring sulfation. One method is to apply a saturated charge and then to compare the specific…

Energy audit is a tool to enable energy management in a commercial or residential enterprise. It is a technique used to establish the pattern of energy use, and identifies the areas where energy can be saved or where energy can…

The process of introducing impurities into an extremely pure semiconductor for the purpose of modulating its electrical properties.

Distributed generation generally refers to the small scale generation of power. The distribution energy resources includes the solar and increasingly play an important role for the eletric power generation system.
