Solar Energy, offers the best alternative energy solution. The freely and abundantly available light from the SUN can be utilized as Photovoltaic Energy or Heat (Thermal) Energy through special devices developed and manufactured by sophisticated and high technology processes. Solar Power is cost effective and easy to install. It has potential to cater the growing needs of the power.


Solar Power Pack consists of a PV array which generates DC electricity from sunlight, a battery bank to store the DC energy and a Power Conditioning Unit (PCU) to convert from DC to utility-grade AC electricity, which can be used to run the loads.

Solar Power Conditioning Unit : Solar Power Conditioning unit (PCU) is an integrated system consisting of a solar charge controller, inverter and a Grid charger. It provides the facility to charge the battery bank either through Solar or Grid/DG set. The PCU continuously monitors the state of Battery Voltage, Solar Power output and the loads. Due to sustained usage of power, when the Battery voltage falls below a preset level, the PCU will automatically transfer the load, the Grid/DG power and also charge.

Once the Batteries are charged to the preset level, the PCU cuts off the Grid/DG Power from the system and will restore to feeding the loads from the battery bank & also restore to charging the battery from the Available Solar power. The PCU always gives preference to the Solar Power and will use Grid/DG power only when the Solar Power/ Battery charger is insufficient to meet the load requirement.
