Renesola Saturn - Bi-Facial 580W+115W Solar Panel - Full Pallet

This option is recommended for projects on the roof or ground. The pallet of 36 panels is packed in the factory and arrives with the "flash report" of this particular batch. Each solar panel has a unique serial number. 

The bifacial panel will catch the sun rays from different directions, the back side of the glass can absorb the light from reflection and generate up to 115W additional energy.

The unique feature of these panels is the additional energy production from the back side due to the radiation being reflected on the ground. The amount of energy depends on the following factors:

Albedo Factor is the amount of sunlight diffusely reflected by an object and varies according to the time of year, the season and the material covering the ground. 

Solar Panel Features

• Bifacial technology enables additional energy production from the rear side of the panel by up to 20% 
• Glass-to-glass lamination extends the product life to 30 years with annual power degradation of less than 0.4% 
• The hot spot risk is reduced which is the main cause for early failures. The power and heat are evenly distributed on both sides of the panel.
• Half-cut solar panels have 50% shorter internal wiring, hence 50% lower resistance losses. 
• Thinner inter-cell busbars mean more sunlight can be absorbed.
• Work at different angles even at 90 deg (vertical, for example on a fence) as long as they face the equator.

Thermal Factor for double glass PV

The dual-glass modules have also better thermal conductivity compared to the conventional back sheet. The thermal resistance of dual glass is slightly lower than that of ordinary modules. The smaller the thermal resistance, the better the heat conduction.
