Solar Panel Perc Technology

Optimisers along with micro inverters are generally known as mlpe or module level power electronics which as the name suggests consists of small power conversion units attached directly to individual solar panels.

Solar panel perc technology.

Perc solar cells are modified conventional cells that enable the cells to produce 6 to 12 percent more energy than conventional solar panels. To improve the number of photons that are captured by a solar cell perc technology adds two additional layers at the rear of the cell. Perc technology boosts efficiency through the addition of a layer to the back of a traditional solar cell which provides several benefits to the cell s production. How perc improves solar cell efficiency.

Perc cell technology defines a solar cell architecture that differs from the standard cell architecture that has been in use for three decades and that is usually featured in all photovoltaic manuals. Perc panels have a higher energy density per square foot and perform well under low light conditions and high temperatures. From top to rear. Screen printed silver paste front contact.

That is it can turn a boring old 16 efficient panel into an exciting 17 efficient one. Perc which stands for passivated emitter and rear cell or passivated emitter and rear contact is a new technology aimed to achieve higher energy conversion efficiency by adding a dielectric passivation layer on the rear of the cell. A technology which is becoming more popular is the addition of dc power optimisers within the solar panel. Solar panels made from perc solar cells typically perform better than traditional panels in both low light conditions and high temperatures.

High efficiency solar panels for epcs installers and contractors mono perc solar panels for commercial and utility scale projects with a technology that combines rear wafer surface passivation and local rear contacts to maximize light capture mono perc solar modules are paving the way for dramatically increased pv system efficiency. Perc is one technology used to improve that capture rate. As of today the vast majority of crystalline solar cells produced follow the structure presented hereunder. List of perc solar panel manufacturers.

Currently around one quarter of new solar panels are perc and the figure may reach 50 in 2020. This allows some of the sun s rays to reflect back into the solar cell giving them another opportunity to be turned into energy. The reason it has become popular is because it adds little to the cost of solar panels while increasing their efficiency by around one whole percentage point.
