  • Encapsulated Design Resists Corrosion
  • No Maintenance Required
  • Quick and Easy Installation


Alpha silicon solar modules use breakthrough technology perfected by nearly 40 years of manufacturing technology. These modules use a textured cell surface and tempered glass to reduce reflection of sunlight. The anti-reflective coating provides a uniform blue color and increases the absorption of light in all weather conditions. These solar modules can be applied in many areas including building roofs, photovoltaic power plants, telecommunication, hubs, weather stations, broadcast towers, navigation marks, railways and road intersections.
