PERC MONOCRYSTALLING SOLAR PANEL

PERC MONOCRYSTALLING SOLAR PANEL

Scientists and engineers are constantly innovating to provide the most bleeding-edge technology to solar PV systems to boost energy generation and speed up end users' return on investment. One of the most recent introductions to increase solar panel efficiency has been the development of a new industrial process of advanced passivated emitter and rear cell (PERC) technology.

The introduction of PERC technology has increased solar efficiency, which translates to faster ROI and more savings for end users.

Inside of a solar panel rest cells made of silicon. A typical 12v panel will house about 36 cells, with each cell contributing to the panels' overall energy generation. Conventional monocrystalline cells have an emitter layer on the front side and a standard back surface field. PERC technology lets solar cells absorb more light and gives them a higher internal reflectivity, providing end users with more possibilities for tilt and installation options. This is great news for those with unorthodox spaces or locations that might not initially seem the best for a solar PV installation, as the PERC tech allows for much greater array layout flexibility. PERC tech is ideal for rooftops, elevated ground, desert or snowy environments or on-water applications. This leads to increased energy density and electricity generation for the system. Greater energy density significantly reduces the levelized cost of electricity (LCOE) for a solar PV installation. By effectively leveraging the modules with PERC technology, end users can obtain a much faster ROI. PERC panels also perform better under low-light conditions and high temperatures.

A cell conversion efficiency of 25.6% brought Panasonic the efficiency world record in 2014. (at R&D level)
