Small Solar power Panels

The flat-plate photovoltaic (or PV for short) panel designs are most commonly used for small solar power systems. They can track the sun’s movement or be fixed in one position. This PV array is made of PV modules in a set position on a flat-plate. There are a number of advantages to this type of fixed array: They are lightweight, No extra equipment and have no moving parts.
These panels are appropriate for a lot of locations, like most suburban homes. Their direction to the sun is frequently at an angle that is less than optimal because they are fixed in one place. When compared to the tracking array, the fixed type are less efficient. This however, must be weighed against the higher initial cost of the tracking system.
Energy PerformanceThese types of Solar arrays are intended to provide particular amounts of electricity under certain circumstances. Cretin factors are considered when determining array energy output:
Classification of solar cell electrical output Determination of the loss of quality factors related to this type of array design Adaptation of ecological considerations toward solar cell temperatures Estimate of array energy output ability. When calculating the electricity requirement of a project, one or a combination of the following performance criteria can be used:
Energy output - energy or watts obtainable at the energy regulator, specified either as peak energy or average energy created in one day.
Electrical output - the quantity of electricity (watt-hour or Wh) created throughout a certain period of time. The parameters are the production per unit of panel area (Wh/m²), production per unit of panel mass (Wh/kg), and production per unit of panel cost (Wh/$).
Exchange efficiency - defined as "electrical output from the panel" ÷ "solar energy input from the sun" × 100%.
This last consideration is often given as energy efficiency, equal to "electrical output from the panel" ÷ "solar energy input from the sun" × 100%. Electricity is normally measured in units of watts (W), and energy is normally measured in units of watt-hours (Wh), or the electricity supplied in watts during an hour.
