Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

The solar panel is a monocrystalline photovoltaic system consisting of 60 cells. The open-circuit voltage of the panel is 37.7 V and the short circuit current is 8.7 A. The maximum system voltage is 1000 V. The vertical axis wind turbine component has a cut-in wind speed of 2 m/s and a cut-out wind speed of 18.5 m/s. The wind turbine has a mechanical braking system to prevent any damage to the system if the wind speed goes beyond 18.5 m/s. The material used for the frame is galvanized G-90 steel and aluminium. The electronic enclosure rating of the system is IP53. The turbine is also manufactured using galvanized G-90 steel.

Manufacturer specified performance targets Designer / Manufacturer specified targets

The system is designed to generate energy even at lower wind speed conditions. Coupled with the solar panels, the system can generate energy 24 hrs/day and 365 days/year under ideal conditions. The system incorporates a Vertical Axis Wind turbine which can harness wind energy from multiple directions making it more efficient. It can be either used as an on-grid or as an off-grid system.

Vetted performance Findings of manufacturer evaluations or independent testing centers

Testing has been conducted using the IEC 61400-2 standards.

Testing organizations Independent lab, academic research centers, etc.

Testing was completed by the National Institute of Wind Energy.

Safety Potential hazards / risks related to operation of this product

Standard precautions for operating solar and wind turbine systems should be taken.

Complementary technical systems Performance of this product is improved with another technology (eg. Cookstoves and Wind-blocking skirts)

An on-board battery charge controller grid-tied inverter is an optional extra to allow for the system to be connected to a battery.
