Global warming is an environmental threat our planet faces today. The global warming is 100% a manmade problem due to mismanagement of nature-gifted natural resources. It is predicted that the Earths average temperature shall increase by 6.5OF by the year 2025 & the earth will be a much diff erent place than we know it today.

What is the solution to this burning problem?

Generate your own power with Renewable Energy like Solar & Wind. The Technology is much in common-man’s reach. The commercial- tariff areas are affected most due to steep rise in tariff . Imagine tariff at Rs. 20/ unit in next couple of years. A typical 1.5T Air conditioner along with office fans & lights shall consume approx 40 units per day i.e. approx 1000 units/ month. Hence the expenditure shall be Rs.25000/ month inclusive of maintenance cost. Again the Electricity may not be available round the clock. That means you have to spend additional for generator & cost of fuel. The total expenses shall touch Rs.40000/month for a small office.

Go Green for Cooling Technology

  • Absorption chilling technology
  • Air-conditioner (only cooling)
  • Fridge/bottle coolers.
  • Room- coolers (water filled)
  • Cold storages.

Main features of this technology are

  • Solar-Panel life is 25 years.
  • Latest Solar Torr tubular battery life is 10 years.
  • Solar energy is available almost for full year.
  • Conventional Electric-supply can be used as a standby.
  • Breakevenpoint is approx 2 years or even earlier.
  • You are helping to reduce Global warming.

Absorption Chilling Technology

The absorption chiller, in the most simplistic sense, allows a building to use thermal collectors to power its air-conditioning. The water heated by solar energy in these collectors is used to initiate a thermal dynamic process involving low-pressure chambers that chills water to around 44OF. The chilled water is then brought to a series of copper pipes that effi ciently cool air blown through the pipes and into the home. Except for a few pumps, the system is entirely passive, has no moving parts and requires no electrical input.

Most other prototype models in development are natural gas-fired or use hydro fluorocarbon refrigerants that are known to have a significant impact on earth’s ozone. Solar absorption chillers are one of the most effective and efficient ways to heat and cool buildings using only the power of the sun. These chillers are powered by heat (hot water) which is supplied through evacuated tube collectors. The solar collectors collect thermal energy from the sun and transfer it using a glycol-water solution, along with a system of pipes, pumps and controllers.

Solar Electronics is a systems designer, integrator and supplier for solar air conditioners that use solar powered chillers. By providing the site survey, project management, design and engineering, Solar Electronics will guide you from start to finish on your solar air conditioning projects.

100% Solar –Powered Air- Conditioner (Only Cooling)

The heart of Air-Conditioner is the compressor. The above mentioned Air- Conditioner (From Solar Electronics, India) uses 48V DC Compressor powered by BLDC motor. The indoor & outdoor unit fan motors are also 48V DC powered @ 1000 to 1500 rpm. The total wattage consumed by the above model is max. 800W at 48V DC for a typical 9000BTU Air- Conditioner (Only Cooling). Hence 48V/1200W solar panel is enough to drive the Air- Conditioner for full day during office hours. Using 48V/1500W panel with additional 48V/100AH battery shall prolong the backup in the evening & shall also help to store the solar energy during weekly off . This helps you to power your office on your own, thereby keeping conventional electric supply as standby. Approx.200 to 300 sq.ft. area is enough for solar panels mounting preferably on rooftop.

100% Solar Powered Fridge/Bottel Cooler

100% Solar- Powered Fridge

Fridge plays a vital role in our daily Urban OR Rural life. Solar fridge model SLR/fridge/100 form Solar Electronics, India is designed to work at 24V DC at 150W power. The compressor used in this fridge (from 100 ltrs to 165 ltr.) typically uses 24V DC 150W to 240W DC compressor which is directly compatible to solar panel Input (of 24V/300W) or battery input. Other sections of the fridge are practically same as conventional fridge. This 100% solar powered fridge from Solar Electronics, India is very ideal for Indian market.

100% Solar powered water purifier/cooler

100% Solar Powered Room Coolers (Water filled)

Solar Coolers from Solar Electronics, India uses BLDC motor which is 12V DC or 24V DC operated for fan – motor & water – pump motor, which is directly compatible to Solar input or Battery input. These coolers also can be powered by conventional electricity. Very ideal for Rural & Urban Indian market. A typical solar cooler model SLR/cool/DC24/016 shall consume total 50W of power & is ideal for 160 sq.ft. room. 24V/100W Solar panel is enough to run the cooler for the full day & also shall charge battery for additional 4 hrs. backup.

100% Solar Powered Cold Storage

Cold storage is vital for preserving perishable products like Grapes, milk etc etc & consumes lot of power. However continuous failure-free Electric power supply is very crucial during summer & through out the year. Model. COLDSOLAR/100 is a typical model from Solar Electronics, India, which is 100% powered by solar input of 100 sq.ft. area. The model consists cold storage roof top of Solar panel, Cold- Storage walls made up of sandwiched panels & solar powered Compressor systems. The model varies from 100 sq.ft to 1000 sq.ft. with cascading effect.
