1. A PRESENTATION ON SOLAR WIND HYBRID SYSTEM BY

2. BACKGROUND For remote and inhospitable areas – Reliable Electricity supply is not available.

3. BACKGROUND Severe shortage of man- power in Telephone Exchanges – Small Telephone Exchanges are unmanned. Even refilling of diesel is a problem.

4. BACKGROUND Alternative approach is necessary : Where demand is high. Potential for renewable energy exists.

5. BACKGROUND One such site was identified (in co-ordination with Telecom) One such site was identified (in co-ordination with Telecom) KAVUNJI – located at considerable height on a hill top in the Western Ghats range.

6. BACKGROUND Reliable Electricity supply not available. Substantial demand for Telecom services. Load Demand of 5KVA (4KW)

7. BACKGROUND Solar wind hybrid energy system is proposed. Solar Modules – 48V DC 1000W wind turbines – 48V DC

8. BACKGROUND Battery – 48V deep cycle type for 2 days autonomy. Controller for Solar DG & wind.

9. During period of bright sun light (peak summer & winter) solar energy charges the battery and creates enough reserve for darkness. During monsoons etc., micro - wind generators produce most of the energy since wind speed is high. MODUS OPERANDI

10. Hybrid controllers combine both powers to charge the batteries or provide power to inverter. Inverter modulates this to quality power. MODUS OPERANDI

11. FEATURES OF SOLAR MODULE 15.64 KWp solar modules configured to 48V DC Space required – 500 to 550 sq.mts

12. FEATURES OF WIND GENERATOR Aerofoil blades (3 Nos.) made of carbon / fibre composite material. Self lubricated ceramic bearings. Start up wind speed – 3mts/ sec

13. FEATURES OF WIND GENERATOR Built in brakes and angle governor to protect at higher wind speeds. Turbine system interfaced with SMPS based charger. Automatic regulation mode for over charge protection.
