  • Introduction of solar system

    Green power, no fuel, no pollution, Abundant natural resources, wide applicationSafe, reliableAnnual growth rate of need and production: >30%.Monosilicon and polysilicon in market of photovoltaics: >80%.depend on price of Si, the price is inclined to reduce, but still expensive relatively.World solar production in last 7 years,From 2008 Deep Research Report on China Solar Cell Industry Why Soar Energy Soar ProductsWidely used Solar products (MW)

  • Main components of solar systemGenerate electric under the illumination.High transfer efficiency Store the energy of solar array.Large capacity to supply power when it is cloudy continuously.The central control device to connect the solar array, battery and the load. Should be reliable.Standard knighthead: 0.6m, 1.5m, 3m could be customized designSolar PanelBatteryControllerSupport System

  • Calculation as belowLoading Assumption: 1500W Average time of the sunshine radiation:5hours; Equipment working time 18hours, not 24hours, considering DG will be worked in the hybrid solution.Wsolar = Vm / Vr * Wload / Tsunlight / =35V/24V*1500W*18Hours/5Hours/0.85=9264WN = Wsolar / Wboard=9264/175=52 set solar panelsSo, 52 sets of solar panels is provided for a hybrid solution, and the DG & rectifier should be provided for the battery recharging after some days.C = KB * Wload * Nrainy/cloudy days / Vsystem/DODMAX=1*1500W*24Hours*2days/48V/60% =2500AhSo, the battery back-up time is nearly 2days depending on the site loading.

  • Case 1: The solar power solution for RoshanThe first solar system for BTS in Afghanistan

  • The solar power solution for RoshanCustomer requirements: Solar solution and achievements : Existing BTS sites with two generators, Very high OPEX, Low reliability Reduce the OPEX, Improve reliabilityHybrid solution, The existing DG work as backup First trial site was finished in 1 month; Won the PO of 14 sites Jan. 2008;Save OEPX 350,000 USD every year.First solar system for BTS in Afghanistan

    Solar*The first case I want to show you is Afghanistan ROSHAN solar system, this is the first solar system for BTS in Afghanistan.

    We are the first solar vendor enter Afghanistan marketing,In this case, Customer face 2 serious problems: one is high OPEX ,because DG consume lots of fuel every day, another is low reliability, DG breakdown frequently, So how can we reduce OPEX and improve reliability? First, Solar send senior expert to survey and collect detail requirement, then we design a hybrid solution using existing DG work as backup. First trial site was finished in 1 moth; then we won the 14 sites PO in Jan. 2008; By Solar hybrid solution ,helping Roshan save 350,000 USD per year. after this, we also won a solar PO from etisalat.

    We do suvery with customer

    In Rosh case, there are 2 existing diesel generators to supply power for BTS, about 30 thousand USD OPEX per year per site, OPEX is very high, and DG breakdown frequently, so how can we reduce OPEX and improve reliability?To meet ROSHANs requirement, we proposed hybrid solution, which use solar system and existing DG as backup. First trial site was finished in 1 moths; we won the PO of 14 sites Jan. 2008; This solution helpRoshan save 350,000 USD per year.*The second case I want to show you is the Ethiopia Solar System, this is the biggest solar system for telecom network in the world, 369 sites.
