We strive to be ahead of the market in quality parameters. Our warranty terms are honoured religiously.
The various parameters on which we review the quality of our products are:
•Functionality
•Strength
•Heat conduction
•Rust resistance for long life
•Safety
•Maintainability
All our products undergo strict quality checks during production and before delivery.
We strive to be a company having a portfolio covering all Solar Thermal and SPV products, being represented in each district of the country & playing a major role in promoting Renewable Energy and Environment Friendliness.
We design, manufacture, supply, install and commission Solar Energy Equipments such as Solar Water Heaters, Solar Lights, Rooftop Solar projects & Solar Cookers etc. and provide prompt after sale service at competitive prices to individual, institutional and industrial customers by making the systems efficient, cost effective and durable with good manufacturing practices, innovations, complying to statutory and non-statutory industry standards and use of past experience.
Jaysolar also provides Heat Pumps and Heat Pump tanks where the installation of Solar Water Heating System is not possible.
System capacity | 125 LPD |
Average output temperature | 65 deg. C. |
Average input temperature | 25 deg. C. |
Total heat gain | System cap. x temp. difference |
= 125 x 40 kcal = ,5000 kcal | |
Approx. total cost | Rs. 25,000/- (US$1=@Rs.55.00) |
Boiler efficiency | @ 80 % |
Operational days in a year | 300 |
Calorific value of oil | 10280 kcal/kg |
Purchase Cost | @ Rs. 30- per liter |
Specific gravity of oil | 0.8 |
Oil required per day | = Heat gain/ (calorific value x sp. gr. x boiler efficiency) |
= 5000/ 10280 x 0.8 x 0.8 | |
= 0.76 liters | |
Saving per day | = 0.76 x Rs. 30/- = Rs. 22.80 |
Saving per year | = 22.80 x 300 = Rs. 6840/- |
Payback period | = Net cost / saving per year |
= 25,000/ 6840 | |
Payback period | = 3.65years |
Payback period with subsidy | 2.77 years |
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.
