In solar energy panels, the photovoltaic efficiency is what sets the output given by it. The efficiency of any device is a measure of the output got in context to the input given. Therefore , photovoltaic efficiency is decided by the amount of solar energy event regarding 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 potency is the most vital thing.
Folks having homes with bigger rooftops and getting a reasonably good quantity of daylight in the year can install panels with less efficiency. These folks have an advantage of a bigger area and therefore more panels can be installed and compromise can be done with the photovoltaic efficiency of the panels as agreed by the energy requirements of the household. The homes with a small or average area for roof tops have a disadvantage over the ones having a larger roof tops. As the area for installation is restricted, panels with more PV efficiency need to be installed in order to perfectly match the prerequisites of the household.
Corporations 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 affects 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 photovoltaic 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 situation radiation flux i.e. The amount of daylight situation on the panels is kept one thousand Weber / m2. This however is dependent upon 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've got a 400W system in a serviceable area of 30 ft2 and we should decide the potency of it under STC then, our most important step would 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 * ( 30 / 10.76 m2 )
Multiplying the above answer with 100% we get the PV efficiency equal to 14.3%
So it is to be remembered always to check the efficiency of the solar energy panels before installation is made so you invest your hard earned cash cleverly. For folks having homes with large roofs and good quantity of event sunlight, a less expensive 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.
