Torense solar panels (cells), using heterojunction (HJT) technologies, have proven levels of energy conversion efficiency of 24.98%.
Over the next 30 years, the low prices and low degradation ratio of Torense solar panels will firmly establish them as the most economically efficient panels on the market, leaving their competitors far, far behind.

Heterojunction (HJT) is more efficient technology thanks to the properties of the intrinsic amorphous silicon (a-Si:H) “passivation” layer which ensure the superior temperature coefficient of TC = ‐0.25%/K.
Compared to standard c‐Si technology, heterojunction cells generate 35% more kWh/m2 and therefore reach the lowest levelized cost of electricity (LCoE). In our case, the rear of the bifacial module provides from 15% to 50% additional power output, depending on the reflective properties of the surface it is facing (gravel, sand, snow, etc.)

HJT bifacial panels can produce additional energy yield depending on the ground type under them. The second side of the module generates up to 90% of additional power, which depends on the reflectivity of the surface (albedo) on which the module is installed (grass, sand, snow etc).
The advantages of Torense solar panels when compared with similar — so-called high-efficiency cell — products:

Superior temperature coefficient: TC = ‐0.25%/K

Increased daily generation: + 5%

Increased annual generation, particularly for countries with hot climates, resulting from the use of reduced temperature coefficient: + 15%

Substantially reduced degradation factor over the first 1-5 years: –0.5% per year

Reduced (nearly halved) degradation factor over a period of 25 years: –12%

Increased service life: 30 years

Maximum compatibility in double-sided modification

Minimum coating area for maximum generation: + 15% in the case of single-sided panels and up to + 50% in the case of double-sided panels, depending on surface reflectance (albedo)

Proven potential to enhance solar panel (cell) effectiveness by up to 27% over the next three years (R&D)

Increased (cell) growth factor: + 0.75% per year
