Self-Consumption Solar Power Projects by Facility Type

Cutting CO₂ and Electricity Costs with Customized Solar Systems

As the global demand for sustainable energy grows, self-consumption solar power systems have become essential in a wide range of facilities—from factories to schools. The most effective system design depends heavily on the type and structure of the building. In this article, we outline the best solar system configurations for common facility types, with Japan as a key example.

🏬 Shopping Centers

Large-scale solar with peak-hour efficiency

Shopping malls consume high amounts of energy during business hours. A large solar capacity is needed to meet the daytime demand spikes.

• Use carport or metal roof systems for extensive surface area.
• Combine with battery storage to balance evening demand.

Recommended Systems:

• ソーラーカーポート取付システム
• メタル・ルーフ・マウント・システム

🏭 Factories

Rugged rooftop systems for continuous operation

Factories often run 24 hours a day and consume electricity consistently. Many Japanese factories have metal roofs, which are ideal for secure and efficient solar installations.

• Perfect for direct-mount systems using clamps.
• Add batteries to store solar energy for night shifts.

Recommended Systems:

• Universal Metal Roof Mounting System
• Standing Seam Roof Mounting Brackets

🏫 Schools

Flat roof solution with optimal solar yield

Schools operate primarily during daylight hours and often have flat rooftops.その East-West Row Solar Ballasted Roof System is ideal, as it increases panel density while minimizing shading, making it perfect for school buildings in Japan and beyond.

• No roof penetration—safe and maintenance-friendly.
• Maximizes solar production throughout the day.
• Can be paired with batteries for backup or evening usage.

Recommended System:

• East-West Row Solar Ballasted Roof Racking System

🏠 Residential Homes

Compact and scalable solar for households

Residential solar systems are increasingly popular, especially with policies like Tokyo’s solar panel mandates.

• Smaller systems can meet typical household energy demands.
• Balcony and ballasted rooftop setups work well in cities.
• Include batteries for nighttime usage and emergencies.

Recommended Systems:

• Solar Balcony Racking System
• Cement Pier Solar Ballasted Roof System
