Transcripts - Naps telecom references

  • 1. Solar Electricity Systems Since 1981 Experience and Expertise Naps Systems Oy / Pakkalankuja 7 / FI-01510 Vantaa / Finland www.napssystems.com / +358 20 7545 666 / +358 20 7545 660
  • 2. Naps Systems Ltd. Naps Systems is a solar electricity systems company We provide complete solutions We operate on 4 continents and we have supplied systems for over 120 countries We have more than 25 years track record in the industry
  • 3. Core competences Expertise in sizing, designing and specifying systems Extensive expertise in batteries Extensive expertise in module production
  • 4. Our telecommunications applications Extremely reliable Operate in all weather conditions Little human intervention as possible Equipped with an alarm signal and studied in order to sustain the station’s operation for a period long enough for maintenance personnel to arrive Fuel cost and replenishment visits are saved annually “Telecommunication lines often pass through remote, uninhabited areas where no infrastructure exists” Naps Arctic GSM/NMT Base Station
  • 5. System management An intelligent controller increases system life All of our larger system controllers are: Individually tailored to specific project requirements Ideal for places where large power, extensive data logging, and flexible system control is required Optimizing the battery life time by controlling its charging and by preventing excessive discharging Deciding when the back-up generator (if in the system) needs to be connected or disconnected Providing the essential user interface for the system, showing status of charging / discharging, data display, data logging, alarm signaling and remote communication
  • 6. Solar electricity vs grid connected General Differences Solar electricity + mobile system + decentralised energy production + no transmission losses + low investment costs + fast and easy installation - limited power supply - requires special low voltage devices Grid connection + even power supply + matches with sudden large power demands - high initial investment extensions expensive transmission losses
  • 7. Solar electricity vs diesel generators General Differences Solar electricity + Easy installation + Almost maintenance free + Unattended operation + Long life expectancy + High reliability + No fuel, no emissions + No excess heat + Low overall lifetime cost - High initial costs Fairly large battery capacity needed Diesel + Easy installation + Low initial costs + Can be portable - Fuel supplies expensive High maintenance costs Typical service interval 250 hrs (every 10 days) Frequent site visits Separate equipment room Short life expectancy Low efficiency & reliability Noise and emissions Excess heat High overall lifetime cost
  • 8. Case of study, Lapland - Finland Telecom Operator TeliaSonera's Mobile Phone Base Station in Sokosti Solar modules 168 pcs 50Watt System control unit, arctic version of the NSCi GSM/NMT station consumption 800 Watts Battery fuse box Panel centres Vented single cell 3600 Ah batteries 48-Volt system Diesels 12,5 kVA each A good battery keeps operating costs down
  • 9. Case of study, Lapland - Finland Telecom Operator TeliaSonera's Mobile Phone Base Station in Sokosti Conclusions: Reliable thanks to the design trimmed to suit the required load 70% of the time solar electricity runs the station Compared to the grid connection required less financial investment (1/40) Quickly set up (4 weeks), revenues to the operator started coming in much sooner than with conventionally powered systems Obtaining permits from the authorities was easy as the solar required no power lines or even road into a delicate wilderness area Solar modules withstand extreme weather conditions Authorities are pleased with system that can be removed - at the end of its life time - leaving no trace to the environment
  • 10. Case of study: Mongolia Telecom Mongolia's 800-kilometer Telecom Backbone Capital Centre province Repeater station connected to electricity Repeater station powered with solar electricity
  • 11. Case of study: Mongolia Telecom Mongolia's 800-kilometer Telecom Backbone Conclusions: Significant savings - the client’s operating costs reduced 90% thanks to: The status of the repeater stations is monitored remotely - no need to frequent visits As diesels are used only for back-up the life of the equipment has increased and the consumption of fuel has reduced “Power supply to these stations was very expensive in terms of maintenance and refuelling costs, and in-time refuelling was not guaranteed, as Mongolia is completely dependent on imported oil products. From this reason we chose solar electricity to provide reliable and economic alternative to power repeater stations in remote area.” Dr. Namjil Enebish, Post and Telecommunications Authority, Mongolia
