Comparison Of Solar Water Heaters With Electrical Geysers

Cost of electricity

RS. 5.00 per unit (kWh)

Total heat gain kcal/ day

System capacity x Temp. difference

= 125 x 40 = 5000 kcal/day

= 5000 x 4.2 kJ/ day = 21,000 kJ/day

Total heat gain

= 21000/ 3600 kWh/ day

Saving in electricity

= 5.83 kWh / day

Saving in electricity cost

= Units saved x cost / unit

= 5.83 x 5

Saving / day

Rs. 29.15

Saving per year

= 29.15 x 300

= Rs. 8745

Payback period

= Total cost/ saving per year

= 25000/8745

Payback period

= 2.85years

Payback period with subsidy

19000/8745 = 2.17 years


Actual payback period becomes much shorter if the periodic rise in the cost of oil/ electricity, maintenance and handling charges for geysers or boilers and depreciation allowance available are accounted for.

With MNRE upfront subsidy under JNNSM, the cost of the system becomes Rs. 19000/- and payback period works out to 2.77 years and 2.17 years respectively.
