In solar panels, the photovoltaic efficiency is what decides the output given by it. The efficiency of any device is a measure of the output obtained in context to the input given. Therefore , photovoltaic efficiency is decided by the quantity of solar power event with respect to the quantity of electric current produced. More the photovoltaic efficiency, the better is the quality of the panels. While installing a solar cell, knowing the efficiency is the most vital thing.
People having houses with bigger rooftops and receiving a fairly good quantity of sunlight in the year can install panels with less potency. These folks have a merit of a larger area and thus more panels can be installed and compromise can be done with the photovoltaic efficiency of the panels as agreed by the energy needs of the household. The homes with a small or average area for roof tops have a drawback over the ones having a larger roof tops. As the area for installation is restricted, panels with more PV potency have to be installed in order to perfectly match the prerequisites of the household.
Companies that produce the panels measure the photovoltaic efficiency in the following way. First think the maximum power ( Pmax ) to be 200W. The area of the panel is the deciding factor behind the employment of this 200W power and influences the efficiency of it. The power output per unit area of the panels sets the PHOTOVOLTAIC potency.
The maximum photovoltaic efficiency ( 951;max ) of a solar power cell is given by the equation
951;max = Pmax / ES, ysw * Ac ; 951;max= Maximum efficiency,
Pmax= Maximum power output,
ES, ysw= Event radiation flux and
Ac= Area of collector.
In standard testing conditions ( STC ), the incident radiation flux i.e. The quantity of daylight event on the panels is kept one thousand Weber / m2. This however is dependent on the location of the places and the testing condition. To grasp the process of figuring out the photovoltaic efficiency of the panels lets us follow these steps. Presuming we have a 400W system in a serviceable area of thirty ft2 and we have to decide the efficiency of it under STC then, our primary step will be to convert the area available from ft2 into m2. As we know Pmax is 400W and then by calculating ES, 947;sw we can have the following calculation with the formula.
951;max = Pmax / ES, ysw * Ac
951;max = 400 W /1000W / m2 * ( thirty / 10.76 m2 )
Multiplying the above answer with 100% we get the PV potency equal to 14.3%
So it is to be remembered always to test the efficiency of the solar cells before installation is formed so you invest your hard-earned money cleverly. For folk having homes with big rooftops and good quantity of situation daylight, a cheaper and less efficient panel will do the job. But for the roofs with smaller area, the photovoltaic efficiency should be more . Panels selected with the ideal selection of photovoltaic efficiency are the key to meeting the energy requirements of the household.
