N-Type TOPCon PV Modules
Unmatched Quality Ultimate Efficiency
N-Type TOPCon isn't just an upgrade — it's a rethink of how solar panels should perform. ADM Solar's N-Type TOPCon Modules are built to deliver more power, lose less energy over time, and outlast conventional P-Type panels by a significant margin. With lower degradation rates and superior performance in real-world conditions — including high temperatures and low light — these modules work harder, for longer. We offer one of the widest wattage ranges available, making it easy to find the right module for any project — from rooftop systems to large-scale solar farms.
Next Gen N-Type PV
Technology
In P-type solar cells, the silicon base layer is doped with boron, creating positive charge carriers known as electron holes. In contrast, N-type solar cells use phosphorus-doped silicon, which produces free electrons as the primary charge carriers. This enables better conductivity, lower energy loss, and higher overall efficiency.
