Solar Panels
Monocrystalline Solar Panels
The color of monocrystalline solar panel is black and it gives high efficiency approximately 18-20% generally the lifespan of the panel is 25-30years. It is possible to generate more power in less space. Gives more performance even at higher temperatures. Also works well in cloudy weather.

Polycrystalline Solar Panel
Polycrystalline solar panel is an old and affordable type of solar panel made of multiple silicon crystals. Its efficiency is approximately 15-18%. Its color is blue with crystal pattern. And its cost is less than monocrystalline. Its life span is approximately 20-25 years. This requires more roof space.

Advanced technology solar panels
PERC Solar Panel- PERC (Passivated Emitter and Rear Cell) is an improved monocrystalline technology. Its efficiency is 20-25%. There is a special reflective layer on the rear side. It absorbs more sunlight and generates more electricity.
Bifacial Solar Panel- This panel captures sunlight from both sides, front and back. It has also been used to reflect light from the ground. It is achieved by generating 10-30% extra electricity.
TOPCon Solar Cell- Full form of TOPCON is (Tunnel Oxide Passivated Contact). Its efficiency is approximately 20-23%. Performance in heat has improved. This is for long term stability. The next generation of PERC is here.
Heterojunction Solar Cell (HJT)- In this technology crystalline silicon thin-film layers are used. Its efficiency is 20-23%. Gives best performance at high temperature. That’s why premium solar technology has become important.
Interdigitated Back Contact Solar Cell (IBC) – It is located on the back side of the wiring panel. There is no metal line on the front side. Its efficiency is quite high, almost up to 25%.
