460 Wp N-Type TOPCon Bifacial Monocrystalline Solar Panel Black Frame
460 Wp monocrystalline bifacial solar panel with N-Type TOPCon cells and a double-glass, black-frame design. Module efficiency up to 23%, extra energy yield from the rear side and a 30-year warranty on both product and performance. Eco Delta ECO-460M-48RHC-DGBF model.
The 460 Wp Eco Delta ECO-460M-48RHC-DGBF solar panel is a latest-generation monocrystalline bifacial module with N-Type TOPCon cells and a double-glass structure. It combines high efficiency (up to 23%), low degradation and energy production from the rear side as well, making it ideal for residential, commercial and industrial photovoltaic systems.
Why choose an N-Type TOPCon bifacial panel?
N-Type TOPCon (Tunnel Oxide Passivated Contact) technology delivers a better response to diffuse light, a more favourable temperature coefficient and lower initial degradation (LID/LETID) than traditional PERC cells. The bifacial double-glass design captures light reflected from the ground and surrounding surfaces, with a rear power gain of up to 80% (bifaciality factor); in real conditions this typically means 5% to 15% extra annual energy, depending on the installation.

How much energy does a 460 Wp panel produce?
In southern Europe a well-oriented 460 Wp panel produces roughly 600-700 kWh per year, to which bifacial operation can add further energy. A small system of 6 modules (about 2.76 kWp) generates on average 3,500-4,000 kWh per year: enough to cover a large part of the consumption of a 3-4 person household and to power fridge, washing machine, LED lighting and small appliances during daylight hours. With 10-12 modules you easily exceed the average needs of a home, with surplus energy sent to storage or the grid.
What makes double glass special?
The glass-glass structure protects the cells on both sides, reducing the risk of micro-cracks and ensuring a longer lifespan than modules with a plastic backsheet. Laser-cut half-cell design limits internal losses and drops in output caused by partial shading.

Frequently asked questions
Is the 460 Wp panel suitable for a residential system?
Yes. The 460 Wp format is ideal for both residential and commercial installations. Its high power reduces the number of modules needed for a given kWp, optimising the space available on the roof.
What does bifacial mean?
A bifacial module produces energy from both the front and the rear side, using light reflected from the surfaces below. The real gain depends on the installation (surface type, height above ground, tilt) and is typically between 5% and 15% of extra annual energy.
What is the difference between N-Type TOPCon and PERC cells?
N-Type TOPCon cells offer higher efficiency, lower degradation over time and better behaviour at high temperatures than PERC cells. For the same surface area they produce more energy over the entire life of the system.
How long does this solar panel last?
The module is covered by a 30-year product warranty and a performance warranty guaranteeing at least 87.4% of the initial power after 30 years. The double-glass structure contributes to a very long operating life.
What are the module's dimensions and weight?
The panel measures 1762 x 1134 x 30 mm and weighs about 21 kg, standard dimensions that make it compatible with the most common mounting structures for 144 half-cell modules.
