Leading-Edge Technology

Best-in-Class Solar Panels

PN Solar manufactures our premium-quality PN392 Mono-Gold® Line Solar Panels using the latest high-efficiency N-Type, mono-crystalline, hetero-junction, 5 bus-bar solar cells, with each cell generating over 5.06 Watts of power. Though the solar panels manufactured by PN Solar can be customized in size and shape, the standard solar panels measure 1638 X 982 X 15 mm (64.5 X 38.7 X .57 in.) with each standard solar panel consisting of 72 mono-crystalline solar cells. Each panel has a rated peak power output of 392 watts, which is among the most powerful in the industry.

Advantages of PN Solar’s Solar Panels

PN Solar’s solar panels use a new method of solar panel manufacturing called glass-on-glass. The glass-on-glass manufacturing method uses glass as both the front absorbing layer of the solar panel and as the back layer of the solar panel. The glass-on-glass solar panels operate at lower temperatures because all excess sunlight essentially goes through the solar panel rather than being absorbed by it and heating it.

Glass-on-glass solar panels are more durable because the use of glass on the front and back of the panels provides rigidity and protection to the panels. Since PN Solar’s glass-on-glass panels eliminate the need for aluminum frames around the panels, the solar panels are easier to clean, which ensures optimal performance. Furthermore, the sealed glass ensures PN Solar Ghana’s frameless solar panels will not corrode over time and enables PN Solar to provide 30-year operation warrantees.

PN Solar’s Advanced Manufacturing Processes and Facilities

PN Solar’s PV solar panel manufacturing process is divided into four stages:

  1. Ingot formation
  2. Wafer formation
  3. Solar cell formation
  4. Solar panel assembly

During Stage 1, electric furnaces melt metallurgical grade silica into crystallized silica ingots. Stage 2 involves cutting the ingots into manageable bricks and then into 160-micron thick pseudo-square wafers using new diamond-wire technologies. Stage 3, the solar cell formation stage, involves doping the wafers with various chemical elements to transform them into solar cells with a generating capacity of ≥5.0694 watts (peak) and efficiency rating of 22%. And the complete panel are assembled in State 4.
