If you need to supply water beyond the reach of the power lines, then solar power can solve the problem.  Photovoltaic powered pumps provide a welcome alternative to fuel burning engines, windmills, and hand pumps.  Thousand of solar powered pumps are working throughout the world.  These produce best results during sunny weather when  the need for water is greatest.  

SED  Solar Street Lights are immensely useful as stand alone source of light on streets and in premises, gardens and industrial complexes.  It conforms to MNRE specifications. It is a packaged solar powered outdoor lighting system which provides easy and quick way of tapping the solar power. The system is very easy to install needing no special skills, tools or expertise. It provides a steady source of light in areas where conventional sources of mains utility are erratic, unreliable or unobtainable. It is independent and self-contained and hence needs no extra wiring or cables. It saves on costly transmission losses.  SALIENT FEATURES : Bright light of 900 Lumens from 11W CFL. Weatherproof enclosure. Automatic on-off at dusk and dawn respectively. Special solar grade battery of 12V/75Ah. High efficiency inverter with preheat circuitry for 4 pin CFL.. Charge controller suitable to pump in up to 6A of  charging current. Protections against reverse connection of   battery/panel, over charge and deep discharge. Two solar panels of 37W each 2 No-Sun days autonomy  

McLanty is an affordable and highly reliable lighting solution for remote homes where grid power is totally absent. Hence, it is designed with a view to offer it at very reasonable price and high reliability.  It uses long-life SMD power LEDs as the source of light with conical reflector to convert a point source into omnidirectional light.  It uses 6V/4.5Ah SMF battery and 6V/2Wp solar panel.  The daily use of 4 to 6 hours is possible.

The Kits are available for OEMs which are suitable for LED lanterns operating on 6V/12V. These are with full protections and additional mobile charging output is provided. Kits come in ready-to-use conditions with terminals. No soldering needed.

A very economical solution is available for remote areas. It employs LED lighting. A control box houses 12V/7Ah SMF battery, 10Wp SPV,   3 to 4 LED bulbs 3.5W. The box has mobile charging output as well. Available in total package in ready to use form.

 Self contained unit . No need for wiring.  Automatic on at dusk.  Adjustable height to suit individual requirement  Uses 10 W panel. Mounted on the pole.  12V/7.2Ah SMF battery.  7 W CFL  Weather proof luminary fixture housing CFL  Electronics and battery housed in weather proof enclosure.    Full protections against reverse battery, reverse panel, overcharge and deep discharge of battery.  Three LED indications. “Charging”, “Stand by”, “Battery  Low”.    On off switch with three positions, Dim, Bright and Off    Built-in provision for mains charging when sunlight is not available during dark monsoon days.  Modular construction for ease of installation.

Solar charge controller conforming to international norms. 5A capacity, shunt type, PWM controller. LVD and HVD settings inside. Ultra low IVD and OVD. Total efficiency better than 93%. Electronic over load protection with manual reset with back up fuse inside. Self diagnosing indicators.

LED lighting gives a better solution especially in stand-alone Solar system as these are excellent replacement for conventional lighting sources. Not only these are of very high operational life but these give better lumen per watt at very low power consumption.  A typical home lighting system comprises of SPV, smf battery and control box. Individual bulbs are made in attractive ABS moulding with built-in driver to give constant illumination over entire range of battery 6V or 12V. Stand alone system is fully self contained with every thing included in package. It comes in absolutely ready to use condition with no additional wiring to be done. The LED bulbs come in individual moulded unit with simple plug in arrangement to the holders with 4 meter length of cable and a jack at another end to connect to the main control box housing electronics and battery. The control box comes with mobile charging output . Where the grid power supply is very erratic, mobile charging becomes serious problem. This system provides this feature to circumvent this serious issue. Solar Home lighting System comes in two different forms, 12V or 6V operation. Both are extremely cost effective and affordable for remote areas. It replaces with advantages the solar lanterns! It does not however compromise on quality. The electronics is fool-proof designed. It has full protections against battery over-charge or deep-discharge. Charge Controller uses shunt mode of regulation with PWM charging of battery for best SOC. It disconnects the load when battery goes to lower permissible limit. For a typical 12V system, battery limits are set to 11V (lower) and 14.4V (upper). Battery is thus fully protected by controller.  Mobile charging output is SMPS version which gives control voltage and current to charge mobile battery. LED bulbs are made of 30 nos of white LEDs of extra long life with cool white illumination. It has built-in smps led driver inside the individual bulb which not only gives constant illumination over entire range of battery voltage but saves on battery drain as it is a constant power type driver and not a simple constant current type.  For higher wattage requirement, you can use our Charge Controllers of higher current rating. You can use bigger battery bank and our Solar UPS for the same. 

LED based solar street lights are available in various capacities, right from 6W through 30W. They use  high lumen power LEDs in PDC aluminium housing with excellent thermal management. Luminaire uses our microcontroller based McUD81 or McUD161 universal dusk-to-dawn controller/driver with multiple programmable dimming options. The detailed operation is described in McUD81 and McUD161 data sheets.  The housing comes complete with just two pairs of cables, one for battery connection while another for panel connection. It is in ready to use form to be directly used anywhere. The detailed specifications are available here.
