TopCon Solar Panel
What is the Tpcon Solar Panels?
TOPCon Solar Panels is an advanced PV cell technology.Its core lies in the formation of an ultra-thin silicon oxide layer(approximately1-2nm thick)combined with a doped polycrystalline silicon layer on the siliconwafer surface,enabling selective carrier transport and surface passivation.Thisstructure allows a small number of charge carriers to pass through the oxidelayer via the quantum tunneling effect while blocking the majority of chargecarriers,thereby significantly reducing surface recombination rates andimproving open-circuit voltage and PV conversion efficiency.
How to choose TopCon vs PERC Solar Panels?
1.Compared to the previous-generation PERC technology，TOPCon Solar Panels achieves an approximately 1%to 2%higher PV conversion eficiency than PERC cells.
2.TOPConexhibits lower light-induced degradation (LID) and potential-induced degradation(PID) than PERC technology.
3.TOPCon has a lower temperature coefficient,resulting in smaller power losses at high temperatures compared to PERC.
4.N type TopCon is popular in the market than P type due to the excellent performance and will replace with P type.
TopCon Solar Panels Efficiency
In the market,most of the Topcon solar panel efficiency range is from 22%-24.1% with mass production,whereas some tire 1 brand solar panel efficiency will be higher with loss production,such as Jinko TOPCon cell efficiency has surged from 25.1%in 2022 to 25.8%in 2023 and 26.5%in 2024.The Topcon solar panel efficiency is depend on the silicon cell and manufacture technology.
Where to use the TopCon Solar Panels?
Commercial solar system for warehouse
It can be applied to the roof of the warehouse and logistics factory, to meet the normal power load requirements of the logistics warehouse.
Solar panels for factory roof
The electricity generated by solar panels during the day can be used for daily production needs, and the electricity stored in the batteries can be used for the power demands of the factory at night.
Industrial ground mount solar system
Ground-based photovoltaic power can be applied to warehouses, factories, centralized power stations, communication stations, etc.
