Global Warming
Earth is warming! With most of the warming in the last 50 Years
attributes to human activities (That is emission of green house
effect) precipitation pattern are changing and sea level are rising.
Human activity have significantly increased the atmospheric
concentration of numerous green house gasses.
UN report on Global Warming – April 2007
Global warming leads to
“Climate Change”
Good News
The good news is, we have everything we need now to respond to
the challenge of global warming.
We have all the technologies we need, more are being developed,
and as they become available and become more affordable when
produced in scale, they will make it easier to respond.

What have YOU done for OUR Mother Earth?
Sustainable ‘GREEN’ Technology
Why Solar?
• Solar is a fixed cost hedged against rising energy costs.
• Solar provides a compelling return on investment.
• Solar energy systems are highly reliable and have low
maintenance costs.
• Solar is a clean, completely silent energy generation
technology.
• Finally solar energy is abundant
Salient Features
• Savings in Operating Cost in the form of fuel/power.
• 80% Accelerated Depreciation Benefit for ALL solar solutions
under MNRE scheme.
• Sturdy and proven technology since many years.
• Can work for 300+ days/year in Indian conditions.
• Modular design for easy and safe O and M.
• The system can be incorporated easily with existing backup
system.
Available Energy Efficient Solutions
• Air Water Heater
• Solar Dehydration
• Solar Hot Water Solutions
• Solar Street Lighting Solutions
• Solar PV Power Packs
• Solar Home Lighting Solutions
Air Water Heater
It is an instrument/concept where the heat from atmospheric
air is absorbed, and is transferred to water through the
mechanism for water heating using thermodynamic principle,
saving up to 80% energy.
Air Water Heater can extract heat even from Himalayan air i.e.
sub-zero temp (up to -30 oC.).

Benefits - Air Water Heater
• Suitable for hard water
• System auto cut-off due to any component failure
• Independent LED’s for individual component & control
• Possibility of installing Monitoring panel anywhere in the
building (advantageous as system is installed at terrace)
• Up to 100% hot water availability with Dual Tank Design
• Low heat losses from hot water tank as the insulation is
decided based on the particular climatic conditions

Solar LED Street Lights
• Zero electricity running cost
• 80% depreciation benefits
• Autonomous Operations
• Close to a month’s time saved in
newly constructed places as a result
of easy installation (feedback from
builders)
• Cleaner and Greener environment
to breathe!
Solar LED Street Lights
• No laying down electrical wires and digging hassles required
which usually consume close to a month’s time for completion
• Significant cost savings in avoiding to lay down electrical
wires, distribution points, employing labor and doing away
with digging hassles
• Less heat emission and easy disposal due to absence of
harmful substances like mercury
Solar Home Lighting System
Benefits:
• Ideal for rural area
• Works as hedge against raising
electricity cost.
• Store Power at Zero running cost
• LED Bulbs Consume less Power,
hence longer working life for
Backup Battery
