Are HJT solar panels a good choice?

HJT panels recently received recognition for achieving the highest sunlight conversion efficiency of any cell technology, reaching an impressive 24.3% efficiency.It is now possible to purchase REC’s leading HJT panel, the Alpha Pure-R at a price comparable to mid-range options and even lower than some N-Type panels.

Who makes HJT solar panels?

The largest manufacturers of heterojunction (HJT) solar panels are Tesla in the US and Panasonic in Malaya and Japan. In 2019, the solar industry produced 5GW of HJT panels, holding around 5% of the retail market.

How does Heterojunction Solar Panel (HJT) work?

HJT works by converting sunlight into electricity through the following process: Sunlight stimulates electrons at the absorber layer’s P-N junction, moving them to the conduction band and forming electron-hole pairs (e-h). The terminal attached to the P-doped layer collects stimulated electrons and generates electricity which flows through the load.

Why are monofacial HJT solar cells better than heterojunction solar panels?

This three-step process is the reason why monofacial HJT solar cells have achieved solar efficiencies of up to 26.7%. Heterojunction technology, based on traditional c-Si panels, improves the recombination process and other major flaws.

Are flat solar panels a good option for utility-scale solar projects?

While flat PV panels can be installed at a lower cost and with lower degradation rates, there are disadvantages to consider for utility-scale solar projects. When solar panels are installed flat to the ground with no trackers, they are not tilted to the optimal angle to absorb the most sunlight throughout the day.
