Why waste electricity for heating water when there is plenty of sunlight available in your country? Most of the households spend 60% of their utility power on heating water and it may burn a hole in their pockets. Expenditure on utility bill is ever increasing and each unit of utility power we are buying from conventional grid is making our mother earth dirty. Don’t worry, we have solutions for you that will spin your energy meter counter wise and at the same time your footprint will be greener rather than carbon black. DIDAS Solar Water Heating Systems is the coolest solution for your Hot Water Requirement.   DIDAS Solar Water Heaters based on Flat Plate Collectors are reliable and trouble free. · System capacity available 100 Liters /Day (LPD) to 30,000 LPD · Available in standard models and customized models to suite customers specific need. · Hot water temperature available from 60 deg Celsius to 80 deg Celsius. · Minimum maintenance is required. · Reduce water heating bill drastically. · Suitable for HARD WATER also. · Hot water available at late night and early in the morning. · Optional Electrical Heating Element is available for cloudy days.

Solar Charge controller and LED driver is combined in one compact housing. Nine nos. of one watt Led are populated on MCPCB. Each LED can deliver 100 lumen/ watt of light output. A rugged and high performing solar charge controller is combined in the same board. LED populated MCPCBs are housed inside Light heads are  in multiplication of  10 watt blocks like 1x10 watt, 2x10 watt, 3x10 wart, 4x10 watt.

Make your own electricity on your rooftop. Solar rooftop power generator works like a silent power generator. No fuel is required only sunshine is enough. All components will work for 25 years and after that 80% of its rated capacity will be delivered. This kind of system is called Grid-tied Solar power generator. It does not require any storage battery for energy storage instead power generated on the rooftop is instantly sold to power utility company. So you are only paying the difference between the amount of power you consumed and the amount you sold.   If you are paying hefty amount of utility bill consider solar grid-tied rooftop power generator. Business entities are liable to get 80% accelerated depreciation in the first year. That implies substantial tax savings that finally reduces capital cost of the system.   Installed system capacity should be 90% of your power consumption. To get net metering facility you have to install at least 5kW Solar rooftop system.

hot water from solar water heater passes through the heat exchanger fitted inside the air heater. a pump fitted below the heating chamber keep hot water flowing through the heat exchanger (he). High efficiency he instantly make air hot in contact with the surface of he. A fan fitted with the he constantly flow away hot air produced by he into the chamber. Thus hot air is produced as long as we get supply of hot water. hot water from solar water heater passes through the heat exchanger fitted inside the air heater. a pump fitted below the heating chamber keep hot water flowing through the heat exchanger (he).

Black colored metal absorber is placed inside the glass-covered and three side insulated collector. The absorber is actually a hollow box having two openings, one is for cold air inlet and the other is for hot air outlet. The absorber has been designed in such a way that air can stay inside for an optimum period of time for absorbing maximum possible heat during it’s travel from inlet to outlet and gradually become hot. A low powered blower supplies air through absorber circuit. This hot and dry air then passes through a drying chamber where something is kept for drying.
