Wind-solar Hybrid Systems

Introduction

When an aerogenerator and an SPV system are interfaced, the power generation from these is mutually supplemented, and the resultant hybrid system offers a reliable and cost-effective electric supply in a decentralized mode. The wind-solar hybrid system mainly consists of one or two aerogenerators along with SPV panels of suitable capacity, connected with charge controller, inverter, battery bank, etc. to supply AC power.

Advantages

The major advantage of the system is that it meets the basic power requirements of non-electrified remote areas, where grid power has not yet reached. The power generated from both wind and solar components is stored in a battery bank for use whenever required.

Incentives

Subsidy of up to 50% of ex-works cost of the system is provided, subject to a maximum of Rs 1.25 lakhs per kW to individuals, industries, and R&D and academic institutions. The MNES provides a subsidy for community use and direct use by central/state government departments and defence and para-military forces of up to 75% of the ex-works cost of the system subject to a maximum of Rs 2 lakhs per kW. For non-electrified islands, subsidy of up to 90% of ex-works cost subject to a maximum of Rs. 2.4 lakhs per kW is available.

Cost

The cost of the system varies from Rs 2.50 lakhs to Rs 3.50 lakhs per kW depending on the ratio of wind and solar components. The approximate cost of installation, including civil works, is about Rs 10, 000 per kW. Repair and maintenance cost is about Rs 3000 per kW per annum.

Wind-solar hybrid systems have been installed for a variety of applications. Some of them have been installed on islands and in coastal areas. One notable project is a 5-kW capacity wind -solar hybrid system installed on Vagator beach in Goa, which has become a destination point for tourists. The system illuminates 60 CFLs (compact fluorescent lamps) of 18 watts rating each. These CFLs are the only source of illumination on the beach. A 15-kW wind-solar hybrid system has recently been installed at the famous pilgrimage site of Bhimashanker Deosthan, in Pune district, Maharashtra. This system provides electricity to meet the needs of the entire temple complex. It has become a point of attraction for a large number of devotees visiting the temple complex. A large number of wind-solar hybrid systems have been installed in Maharashtra by MEDA, including a unit that provides power to the local area network of computers and other needs in their own office complex in Pune.
