About Solar Panels

Fossil fuels account for 80% or more of the total energy consumed in Japan. It’s been suggested that if we continue to use the oil on earth as we now do, it will be depleted in another 40 years. In addition, we must also consider the impact of greenhouse gases. To actively tackle this issue, our company devotes its efforts to promoting the spread of solar and wind power generation systems, aiming to be a company that creates earth-friendly energy.

There is a wide diversity of types of solar cell modules.
We promote the use of amorphous solar cells, which are optimum for the climate of Okinawa.

Types of solar cells by materials

2. We recommend amorphous

Amorphous solar cells benefit from the following characteristics.

1. Outstanding temperature performance
One drawback of crystalline solar cells is their sensitivity to high temperatures, meaning that their power generation capacity is reduced as summer temperatures rise. Amorphous solar cells have excellent temperature performance—in fact, their power generation capacity tends to increase as temperatures rise.
2. Minimally impacted by shade, with outstanding power generation efficiency
Compared to crystalline solar cells, amorphous solar cells are minimally impacted by shade and demonstrate outstanding power generation efficiency across the entire system. Because they are minimally impacted by shade, they are even suitable for low-angle installation.
3. Low-angle (5°) flat installation is possible.
Low-angle (5°) flat installation enables high-density installation even on rooftop corners. When installed in this way, the module surface blocks the direct rays of the sun and prevents them from entering the building’s interior, which also contributes to reduced air-conditioning costs.

*Low-angle (5°) flat installation is possible.

Due to their configuration, amorphous solar cells tend to be less impacted by shade. (References below)
