Bifacial modules are available for DG projects in Brazil

The Brazilian distributed generation market has a new feature: the possibility of using bifacial modules in its projects. The technology widely used in large-scale projects, such as centralized generation (CG), can now be applied to smaller distributed generation projects.

The panels are available for immediate delivery nationwide. Distribution is being carried out by Aldo Solar, the result of a partnership with Jinko Solar.

“Once again the Aldo Solar demonstrates its pioneering spirit in the Brazilian market, being the first distributor to sell Jinko bifacial modules in the country. Bifacial modules, such as Jinko's 410 W bifacial module, will become increasingly common in solar systems due to their wide range of applications and their greater energy generation, depending on the albedo”, explains Gustavo Silva, Technical Services Manager at Jinko Solar.

“By using bifacial module technology in conjunction with half cell technologies that improve shading tolerance and reduce the module's operating temperature, generating more energy, and MBB technology that reduces effective power loss, we have a better BOS (Balance of System), a reduction in LCOE and, consequently, an increase in IRR (Internal Return Rate),” adds Silva.

“We are very excited about the launch of the Jinko Bifacial 410W Solar Panel in Brazil. Together with the availability of the Tiger Pro 440W Solar Panel, they will bring even more innovation to the Brazilian premium market and should further encourage the growth so desired by the sector”, assesses Aldo Pereira Teixeira, founder and CEO of Aldo Solar.

“Both panels are excellent value for money, on the market with a cost close to previous generation models, but they are more efficient, with greater power and a very small size, which should reduce international and domestic shipping costs, with more Watt-peak. in the same container or on the same pallet”, he concludes.

Energy efficiency of bifacial panels

Bifacial panels generate power from both the front and back, effectively decreasing power. LCOE (levelized cost of energy) of a photovoltaic system. This is possible due to a combination of bifacial cells and glass-to-glass encapsulation. With this, the module can generate more electrical current, which consequently provides greater power delivered in the same physical space occupied by a conventional module.

Jinko Solar's modules, launched in Brazil, have a nominal power in STC of 410 W, open circuit voltage (Voc) of 48,97 V, short-circuit current (Isc) of 10,66 A, efficiency of 20,03% and temperature coefficient (Pmax) of -0.35% / °C. They also have an aluminum frame around their entire perimeter and physical dimensions of 2031 mm × 1008 mm × 30 mm (including the structure), and a weight of 26,6 kg.

The panels also feature mono-PERC cells, half-cell technology and MBB (multibusbar) that reduces effective power loss. They also come with a 12-year factory warranty, in addition to having a linear performance guarantee of 85% over 30 years. The gain in bifaciality depends largely on the surface where it is installed. Different types of surface have different light reflection coefficients, known as albedo.

These modules can provide a 25% gain in energy generation. The distance between the panels and the reflective surface (ground, slab or roof) is also an important factor for greater bifaciality gains. Although they are more appropriate for ground applications and solar parking lots, the modules can also be installed on roofs and slabs. To this end, in addition to technical issues, a financial feasibility analysis of LCOE (levelized cost of energy) must be performed.

Logistics cost gains

The Jinko Bifacial 410 W Solar Panel is 30 mm thick. This means that 35 panels can be transported per pallet. In addition, it offers a very interesting logistical benefit, since it is possible to transport more power per pallet when compared to other panels. According to Aldo, the Jinko Bifacial 410 W solar panel has its performance approved by INMETRO and complies with the Brazilian labeling program. Registration No.: 000696/2020.
