Solar energy can be utilised both for thermal and power generation applications.
The various programmes being implemented under thermal and photovoltaic route are
Solar Thermal Programmes
SOLAR WATER HEATING SYSTEMS - DOMESTIC & INDUSTRIAL
One of the important programmes being implemented is solar water heating systems
for both domestic and industrial applications.
Solar Water Heating Systems are available from 100 LPD to higher capacities in multiples
of 100 at 60ºC & 80ºC. The cost of solar water heating system varies from Rs 150/-
to Rs 180/- per litre of installed capacity. One 100 LPD capacity solar water heating
system can save 1500 units of electrical energy per annum or 265 Kgs of LPG per
annum. The pay back period varies from 3 to 4 years depending upon the fuel / electrical
tariff. Primarily two types of systems i.e. Flat Plate Collectors (FPC) and Evacuated
Tube Collectors (ETC) are being implemented in the State. MNRE is providing soft
loans/ capital subsidy for installation of solar water heating systems. The applicable
Central Financial Assistance (CFA) is Rs. 3300 per Sq.M in case of FPC and Rs.3000
per Sq.M in case of ETC or 30% of the system cost whichever is lower.
The State Government issued orders vide G.O. Ms. No.302 MA, dated 03.08.2004 and
G.O. Ms. No. 506 MA dated 03.12.2004,making use of Solar Water heating systems mandatory
in all functional buildings having a height of 15 metres and above ( above 5 Floors
). Under these mandatory orders, demand has been generated for installation of 30
Lakh LPD systems in 5 major municipal corporation areas. Subsequently, the mandatory
G.O is modified by making installation of solar water heating systems as optional.
A proposal has been made again to the Government to consider to make it mandatory
the use of solar water heating systems.
SOLAR DRYING SYSTEMS
Solar dryers cab be utilised for drying fruits, vegetables, fish and also for industrial
applications like tea leaves drying, timber curing etc. Drying takes place in closed
compartments and the process is most hygienic and adds value addition to these products.
Different models/capacities are available to suit the customer requirements. There
is limited demand for solar drying applications.
SOLAR COOKING SYSTEMS
Different types of solar cookers are being used to cater the cooking needs. These
are Box type solar cooker, Dish solar cooker and Solar steam generating systems.
There is limited demand for domestic solar cooking systems in the State due to limitations
of its use. Solar steam generating systems have been installed in the State for
institutions to meet the cooking needs of large community. The largest solar steam
cooking system was installed on Tirumala Hills, to prepare 30,000 meals in a day.
Further, solar steam cooking systems have been installed at Greyhounds Campus, Hyderabad,
Sanghi Industries, Hyderabad, VEDA Educational Institute, Chilakaluripet, Guntur
Solar Photovoltaic Programmes
SOLAR PHOTOVOLTAIC LIGHTING SYSTEMS
Various Solar Photo Voltaic (SPV) lighting systems like lanterns, home lighting
systems, street lighting systems, etc. are being implemented. As per the new guidelines,
Ministry of New and Renewable Energy (MNRE) will be providing Central Financial
Assistance (CFA) at Rs.90/- per watt for all categories of SPV lighting systems.
The State Government has sanctioned an amount of Rs.50,00,000 under Plan towards
supply of solar lanterns. It is decided to provide a subsidy of Rs.900/- per each
lantern and distribute a total of 5,500 lanterns during the financial year 2010-11.
Considering the advantage of LED lighting systems over CFL lighting systems, it
is proposed to implement all SPV lighting systems with LEDs in place of CFLs.
SOLAR STANDALONE POWER PLANTS
To meet domestic / institutional / commercial power requirements (Off-grid applications),
MNRE has launched a programme called Solar Standalone Power Plants. MNRE will provide
CFA of Rs.90/- per watt in case of systems with battery backup and Rs.70/- per watt
in case of systems without battery backup, or 30% of the project cost whichever
is lower for all categories of users plants.
In case of domestic applications, the CFA will be provided for the capacities upto
1 kW and in case of institution/commercial organisations, the CFA will be provided
for capacities upto 100 kW. In case of pumping activity, the CFA will be provided
upto 5 kW. Further, the domestic and institutions (non-profit) can avail soft loans
at 5% interest rate from commercial banks to meet the cost over and above CFA.
A standalone solar power plant of 100 KW capacity has been set up Jeeyar's International
Vedic Academy (JIVA), near Shamsabad, Hyderabad.
The Proposals in the prescribed formats are invited for Standalone Solar Power Plants
of capacities for 1 KW and upto 100 KW. The proposals in the prescribed formats
shall be submitted along with processing fee of Rs. 5000 by way of Demand draft
drawn in favour of NEDCAP Limited, payable at Hyderabad.
In respect of Solar Water Heating systems, the details shall be submitted in the
prescribed tabular form along with details of MNRE/BIS Certificate for the system
proposed to be installed.
In respect of the specifications of various Solar PV and Solar Thermal systems,
the developers are requested to refer to the guidelines issued by the Ministry of
New and Renewable Energy (MNRE)
