Rooftop Solar Power System

Sharp Rooftop Solar Power System – Self-Consumption Solar Rooftop Solution for Factories and Industrial Facilities is a solution in the field of rooftop solar power / solar rooftop / self-consumption solar power / renewable energy / solar EPC / O&M / energy management / carbon emission reduction / ESG, developed by Sharp Energy Solutions Corporation – SESJ for manufacturing plants, FDI enterprises, warehousing, logistics centers, commercial facilities, and buildings with suitable roof areas for on-site power generation.
The system is used to convert solar energy into electricity and is primarily used directly at the factory or operating facility, helping to reduce electricity purchased from the grid, utilize roof areas, and increase the proportion of renewable energy usage.
Sharp implements the solution following a model of survey – design – equipment procurement – EPC construction – operation and O&M maintenance, depending on the scale, roof structure, electricity consumption needs, and operating conditions of each customer.
The system can be developed from typical factory scale to multi-MW capacity projects. Sharp has implemented self-consumption solar power systems for manufacturing enterprises in ASEAN, including a project of approximately 7.9 MWdc at Cebu Mitsumi Plant in the Philippines and approximately 1.88 MW at the MinebeaMitsumi factory in Lopburi, Thailand.

1. Key Features of the Solution

The system is suitable for businesses that need to utilize factory rooftops to generate on-site power and reduce electricity purchased from the grid.
Sharp can carry out the entire process from survey, design, equipment selection, construction, commissioning to operation and maintenance.
The system's scale is designed based on roof area, electrical load, operating hours, and daytime electricity consumption of each facility.
The electricity generated can be used for production machinery, air conditioning – ventilation, lighting, automation lines, warehousing, and other loads within the factory.
The solution helps businesses achieve goals such as reducing energy costs, reducing CO₂ emissions, ESG, RE100, and sustainable manufacturing development.
