Bifacial modules are available for DG projects in Brazil

The Brazilian distributed generation market has something new: the possibility of using bifacial modules in its projects. 

The technology widely used in large-scale projects, such as centralized generation (GC), can now be applied to smaller-scale 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.

“Using bifacial module technology in conjunction with half cell technologies that improves shading tolerance and reduces the module's working temperature, generating more energy, and MBB technology that reduces effective power loss, we have a better BOS (Balance of System), a decrease in LCOE and consequently an increase in IRR (Internal Return Rate)”, he 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. 

As a result, the module is able to 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 48.97V, 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) which reduces the loss of effective power. It also comes with a 12-year factory warranty, in addition to the 85% linear performance guarantee over 30 years.

The bifaciality gain depends greatly on the surface where it is installed. Different types of surfaces have different light reflection coefficients, known as albedo. 

These modules can have a gain of 25% of energy generation. The distance between the panels and the reflective surface (ground, slab or roof) is also an important factor for a greater gain in bifaciality.

 Although they are more suitable 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 viability analysis of LCOE (levelized cost of energy) must be carried out. 

Logistics cost gains

The Jinko Bifacial 410 W Solar Panel is 30 mm thick. This way, it is possible to transport 35 panels per pallet. Furthermore, it has a very interesting logistical gain, as it is possible to carry more power per pallet when compared to other panels.

According to Aldo, the Jinko Bifacial 410W solar panel has its performance approved by INMETRO and complies with the Brazilian labeling program. Registration No.: 000696/2020.
