Solar panels are touted as energy efficient devices. These photovoltaic modules HIT N330 and N325 achieve up to 36% higher yield per square foot, and help lower the installation and balance of system costs per kilowatt over conventional panels.
The panels use a hetero-junction cell structure made of mono-crystalline and amorphous silicon layers. This design enables them to achieve energy efficiency with the same dimensions as traditional solar panels. The solar panels employ 96 cells compared to conventional 60-cell panels.
The N330 and N325 have 4.95 and 4.88 kWp capacities respectively on 20 × 20 ft (400 ft2) rooftop with 15 modules, while a conventional 60-cell, 260-W panel with the same setup achieves only 3.9 kWp capacities on the same dimension roof.
The pyramid cell structure enables this efficiency, absorbing more sunlight to generate power and provide higher efficiency than rougher, more reflective conventional crystalline structures. The water drainage frame removes water from the panel surface, even in low angle installations, avoiding accumulation or water stains after drying which can reduce power output and harm efficiency.
The solar panels are made using state-of-the-art techniques to perform at high temperatures with minimal degradation on quality or efficiency.
