Solar power generation facilities

Solar power generation is a clean and environmentally friendly energy generation system that does not produce carbon dioxide (C02), which is known to cause global warming. Recently, as part of measures being taken for environmental protection, demand from customers to introduce these systems has suddenly increased.
The merits of solar power generation facilities include not having to be selective about a location for the facilities, the comparative ease of maintenance due to the simple structure, and securement of a power source when disasters occur; based on these factors even further introduction of these facilities is expected in the future.
We have been conventionally accumulating know-how for solar power generation from module installation to line linkage system construction. We use construction technology for our current core products, crystalline modules, and what are expected to be core products in the future, thin film based modules. We have established an integrated system in response to customers' needs including subsidy application, planning, design, construction, and aftercare.
