- Generate additional revenue by utilizing idle land on the roofs of factories, houses, etc.
- Sell surplus power to reduce factory electricity costs & create power sales revenue
- REC weighting for installations on factory roofs (1.5 x REC weighting for 3MW or less in the case of using existing facilities such as buildings)
Construction example

|---|---|
| Advantages of rooftop photovoltaics | 1)1.5 x REC weighting ( existing buildings, capacity of 300kW or less) 2)Self generation purpose: Government subsidy 3)Public house: Reducing public electricity costs 4)No need to secure additional land: Utilize existing facilities |
| Target sites | 1)Apartment, house 2)Parking lot 3)Factory, general building 4)School |
| Review items | 1)Shading effect from surrounding buildings 2)Maximum allowable load such as building vertical load, snow load, etc. 3)Whether it is connected to the grid or not |
| Problems when installing rooftop photovoltaics | 1)Additional foundation construction and waterproofing work on the roof 2)Safety of old buildings: wind load, structure weight 3)Landscape: Damage to the building landscape due to exposure to the exterior of the rooftop |
