Solar
Energy Techonologies - 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.
