Residential Support
This program provides government subsidies for a portion of the installation costs when PV systems are installed in single-family homes or multi-family housing. PV modules are installed on roofs, windows, or rooftops, and the electricity generated is used directly.
For this project, we are applying the same "high-efficiency system from SDN Co., Ltd." that is used in commercial PV plants.

7. Homes that are part of a local government’s mandatory renewable energy program are not eligible for support, except for additional installations that meet the required ratio.
Objectives
By promoting the installation of new and renewable energy systems in single-family and multi-family (including public) housing, the program aims to reduce residential energy consumption and expand the use of new and renewable energy systems. This contributes to greenhouse gas reduction and creates a stable investment environment and market formation for the new and renewable energy industry, thereby fostering the growth of the renewable energy market.
Subsidy Support Criteria
Subsidy support criteria are based on the type and capacity of the energy source (as of 2023).

Building Support
SDN Corporation offers partial government subsidies for the installation of PV generation systems up to 50 kW in all general buildings (excluding buildings/facilities owned or managed by housing/national/local government organizations and buildings subject to installation obligations).
We can provide design and construction considering various environmental conditions such as buildings and parking lots.
