If you have 6.6kW of solar panels in Sydney that produce an average of 26.1kWh/day, but you only manage to self-consume 20% of that, then your savings will be smaller than if you managed to self-consume 40% – or even, ideally, 60%. It's therefore important that the system you choose is appropriately sized for your home and electricity consumption.

What is a PERC solar cell?

If you have any questions, please contact us. Conventional silicon photovoltaic (PV) cells have long been the standard in the solar industry. But as the technology matures and approaches hard efficiency limits, researchers and manufacturers have started to embrace a relative newcomer — the Passivated Emitter and Rear Contact (PERC) solar cell.

How does PERC technology improve solar panel efficiency?

PERC technology boosts solar panel efficiency by solving two big problems found in traditional panels: surface recombination and light reflection. The extra layer on the back of the PERC solar cell reflects unused sunlight back into the panel, giving it another shot at generating energy.

Why should a solar PV installer use perc?

As a result, solar PV installers are able to save time and reduce costs when using the newer PERC standard. This is because fewer panels are needed to achieve the same solar power output. Using fewer panels also helps to reduce the amount of racking, wiring, and MLPE devices needed to connect everything together.
