Rooftop Solar Power Plant installations are generally seen on commercial & Industrial Building. This represents distributed power generation at very close to the consumption point. In these systems, electricity demand from the distribution network can be reduced during peak daytime hours as peak load always coincides with PV production. This is seen useful in reducing transmission demand as well as losses in the grid. Hitachi has launched complete range of string Inverters to match up system design requirements of variety of customers which can meet these applications.

Rooftop Solar Power Plants are generally installed very close to consumption point irrespective of the amount of Power Requirement. Major infrastructure cost as like cabling, transformer & switchgear is saved here in comparison to bigger size or megawatt size Solar Power Plants. This is possible with Hitachi String Inverters which covers wide variety of design needs demanded in these types of applications
