Hybrid Systems
Introduction
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.
