Introduction of solar system Green  power, no fuel, no pollution,  Abundant   natural resources, wide application Safe, reliable Annual 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 Products Widely used  Solar products (MW) World solar energy distribution
Main components of solar system Generate 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 design Solar Panel Battery Controller Support System

Controller Display key parameters LCD display and LED indicator of statement of battery and load. Friendly user interface Protection: Plenty of alarm: over charging or discharging, overload, short-circuit, over-voltage, over-temperature Lightning proof: C grade. Low voltage disconnect :  to ensure constant power of major load Flexible application For solar solution and solar+ diesel generator solution. Main function Intelligent battery management:   adjust the battery statement of charging or discharging,   automatic boost with limited current,   adjust the float-charge voltage Remote monitor  through RS232 、 RS485  History record : accumulation of battery, times of charge and discharge Indoor Controller Out door Controller Floor standing Protection grade: IP 20 Capacity: 30A-400A Wall mounted or pole clasped Protection grade: IP55 Capacity: 30A-200A

Calculation as below Loading Assumption: 1500W  Average time of the  sunshine radiation:5hours;  Equipment working time 18hours, not 24hours, considering DG will be worked  in the hybrid solution. W solar  = V m  / V r  * W load  / T sunlight  /  η =35V/24V*1500W*18Hours/5Hours/0.85=9264W N = W solar  / W board =9264/175=52 set solar panels So, 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 = K B  * W load  * N rainy/cloudy days  / V system /DOD MAX =1*1500W*24Hours*2days/48V/60% =2500Ah So, the battery back-up time is nearly 2days depending on the site loading. Design principles Service requirement per site  9000Wp solar panel 2400Ah battery 200A controller Solar Model Site Configuration 175Wp solar panels: 52 sets 800Ah GEL battery: 3 banks 200A controller: 1 set

Editor's Notes

  1. 太阳能系统主要组成
  2. Solar 所提供电池产品的优势: 有竞争力的价格: 1 、供应商:产量大,与 Solar 有长期稳定的合作关系。 2 、 Solar 的采购量大 齐全的产品系列: AGM , GEL 产品具有良好的性能: 1 、良好的参数特性。 2 、在非洲等环境条件恶劣的地区有过成功应用。
  3. Solar 所能提供的太阳能电池板优势
  4. Solar 提供的太阳能控制器类型及优势
  5. 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,
  6. 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 ROSHAN’s 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 help Roshan save 350,000 USD per year.
  7. 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.
