An introduction to microPower
microPower
Why microPower• About 2 Billion people do not access
electricity – globally• 1.4 Billion people without power by 2030 –
globally [i]• Children suffer blindness from kerosene
lamps in no-power zones [i] “Sustainable Energy for Poverty Reduction” ITDG and Greenpeace report
microPower
Why microPower• Prohibitive cost of solar photovoltaics
-Rs 500 per Wp of system rating
• India’s solar photovoltaic program – 20 MWp installed base Vs 20 MWp per Sq Km potential
• Poor conversion efficiency – barely 10-15% and low output ratings – poor substitute for grid power
microPower
For whom? • Working class consumer• Small dwellings – villages, urban fringes• Poor access to grid power – often stolen• Small load – radio, 2-in-1, torch… new
WLL and CDMA phones, ICT devices• Recurring cost of dry cells • Dry cell disposal presents eco-hazard

VisionScene around a hut, 5 years hence: A school-going child removes charged batteries from a solar charger, which she has loaded correctly,
earlier in the day. She re-loads them on a dichroic reading lamp. Likewise, her family illuminates the home and workplace from a range of high-Lux lamps. A 2-in-1
player provides news and entertainment; a mini-fan expels heat and smoke while water is transferred to a service tank by a mini-pump. Sprayers, sprinklers and drippers service their fields... All these are battery-powered, low-wattage devices.
The family takes informed decisions managing its agriculture, skilled trade or business - as it accesses
basic services and regularly contacts its outstation folk - from a choice of solar-powered hand-held ICT devices.
This family need not depend on public utilities for its most basic needs. A basket of microPower technology, products and services provides an efficient,
transparent and unobtrusive backdrop to this scene.

MissionmicroPower will provide a comprehensive
set of low-cost solutions, involving the conversion and utilisation of renewable energy. The products must be -
• Affordable, without need of subsidy • Whole products, ready to use • Enriched by local entrepreneurs –
support, new applications, kit assembly

Charger Applications
microPower
microPower chargers• Range begins at Rs 50 – for 1 AA cell • Use smallest size of SPV panel to service
battery in 4 hrs = 1 day • Large batteries may recharge in 2 days –
being standby• Amorphous silicon – low-cost and shadow
tolerant

microPower chargers
microPower
LED lamp & flasher• Choice - red / white LEDs• - Flasher operation - low consumption /
continuous duty – higher consumption• 2 nos. AA size batteries for red LED / 3
nos. AAA size batteries for white LED• For small rooms, pathways, fences, etc• Easily visible up to 4-5 Metres in dark

microPower pathFinder• System, comprising charger, lamp and
supporting structures• Multiple tailor-made combinations• Multiple uses, from pathway marking to
small room illumination – as per lamp selected

microStill SWP• Solar Water Purifier – cleans water vapour by
sun’s rays
• Versatile - Mounted over “mutka”, any vessel opening on top, tank with open hatch or floated in still water
• Capacity of approx. 60-80 LPD / Sq Metre .. 300mm dia unit suffices for small family’s daily need

microPack solar packaging• Outer transparent protective cover• Inner heat-trap cover• Absorber-cum-wrap • Keeps food warm in open sunlight• Ideal for open-air catering and relief camps
microPower
Dry Boxes & Chambers• Suitable for variety of preservation
processes – food & agri produce• Transparent skylight – adequately sized to
drying load• Forced air circulation – SPV if feasible • Air-tight space /enclosure • Options – Size, humidity control

vitaPower Rice Cooker• Direct cook & serve – no pots & pans• Cooks for 4 persons at a time• Ideal for rice and lentil preparations - Khichri,
Pullao, Kheer … ample scope for local improvisation
• Also roasts – potatoes, other root vegetables, fish, meat … temperatures as high as 150° C
• Healthful, slow cooking – a typical meal is ready by 12 Noon if loaded by 9 am
