2.2 Cost and performance parameters for solar thermal equipment
Capital cost Rs. 8000/- per sq.m., Heat output 3000/- k.cal per sq.m.per day, i.e., 3 standard heat units of 1000 Kcal. On the
average, the output for 270 sunny days per year, will be 800 units per sq.m. For a 25 year mortgage based financing, the
equated annual installment (EAI) at 5% per year is Rs.400 per sq.m. The capital cost recovery liability for an artisan using
the equipment works out to Rs. 0.5 per unit of heat [1000kcal]. The cost of CNG or LPG currently exceeds of Rs.2/-per unit
of 1000 K cal. For biomass based process industry most of the demand is on sunny days. Substantial incomes can be
generated by processing of wood, bamboo and natural fibers and other biomass processing industries using solar heat.
For rural consumer/ producer communities, petroleum fuels or bio fuel substitutes, required for essential services, can then
be affordable.
3.0 Technology promotion & capability building
3.1 Engineering college at Shegaon, Amaravati and associated experts/ professionals will be providing training &
technology support to the partnership of small enterprise, labour co-operatives/micro credit groups for promotion of the
solar thermal energy and biomass based techniques. Funds are already available for
construction of a building of 200sq.m. area. For the available solar equipment at Shegaon and ballarpur there is no capital
cost recovery liability. Donor assistance is available to cover losses in meeting the financing charges and initial losses in
production of Rs.2 lakh worth of material.
3.2 Technology development is in an already advanced stage for cement saving
technology for producing thin section cement fiber composites and high strength concrete products using process heat at
temperature ranging from 90 to 175 c. These techniques can use natural fibers along with wastes such as fly ash, blast
furnaces slag. Food drying juice concentration for sugarcane & various fruits will be another set of income generating
activities. Trials and demonstration will begin by using the available solar thermal equipments to verify the energy
consumption parameters.
3.2 Donor support is available for fabrication of 50m 2 of solar thermal equipment and
for leasing it to artisanal enterprises at 5% EAI i.e., recovery of Rs. 20000/year for estimated cost of Rs. 400000 [Rs.
8000/m 2 ].
3.3 A report is under preparation on the design development and performance experience
of wood, bamboo, natural fiber and solar thermal energy based construction techniques. Total area of buildings constructed
at various places include G +1 housesand halls exceeds 20000 sft. The energy saving potential of these structures is 70%
of total energy as fossil fuel and electricity used in construction. Functional adequacy regarding strength and durability has
been demonstrated. Rural and small town production units are being set up for wood , bamboo ,natural fiber and solar
thermal energy based energy(steel and cement) saving techniques. The challenge is to make these techniques competitive
in the rural and urban market by availing of EA and concessional credit. Social enterprise is needed to strengthen local
initiative to build partnerships, small enterprise and resource poor/socially disadvantaged house hold organised as labour
cooperatives/micro credit groups.
4.0 Biomass bank deposits for providing concessional credit.
. 4.1 The organization ‘Samwad’ is offering wood & bamboo worth Rs. 80,000/- as a contribution to a biomass bank. Wood
and bamboo will be processed & the sale proceeds will be used as a deposit and combined with loan from local bank at
current market rate. A source of concessional credit is thus available for Rs. 160000 with recovery at equated annual
installment of 5 or 6%
.
4.2 Another deposit fund can be created by buying wood, from farmers presently supplying small size wood to paper mills.
The farmers are presently selling the wood to paper mills at Rs. 2.5/ kg dry weight. The processed cut & round wood can
very well be sold at Rs.7/kg & the wastage can be priced at Rs. 1/- Thus out of 3kg of paper making quality wood, 2 kg
material suitable for construction will fetch Rs. 14/- & the balance can be sold Rs. 1/kg as fuel wood. If the artisan gets the
benefit of EA and credit concession, the final product can be priced at Rs.10/kg., a rate that is competitive in the market.
