      5KV SOLAR SYSTEM COST AND POWER DELIVERENCE ESTIMATION



      1. Nataka kuwa na solar system ambayo itaweza kunipa independent power supply (AC) ya kati ya saa 8 hadi 12, natakiwa kuwa na:
        1. Solar Panels ngapi?
        2. Battery Bank yenye LOAD kiasi gani?
        3. Ningependa kuwa na system ya 5,000 Watts, je, itaweza kutoa umeme wa kutosheleza kwa nyumba nzima ya kawaida, yenye 2 Fridges, 2 Deep Freezers, TV set, two computers (1 desktop, 1 laptop), taa kwenye vyumba tofauti 8, in two wings

      DATA SUMMARY

      Power required 5000w=5kv
      Max time Consumption 12 Hours
      Rate of consumption estimated 4.5kv continuous power
      for 12 hours


      CALCULATION FOR ESTIMATION

      1. Size of battery required (A.H)

      Data
      Let battery efficiency be 60% =0.6
      Maximum safe road for 5kv inverter is 4.5kv
      Battery voltage is 12v

      Solution
      Actual wattage for 4.5kv load with efficiency of 0.6 is
      Actual wattage =4500w/0.6=7500 watt(7.5kv)

      Actual current for efficiency wattage of 7.5kv
      Actual current=7500w/12v= 625 Ampere

      Battery size(A.H)=Ampere x Time
      Battery size(A.H)=625A x 12 hours= 7500 A.H approximate 8000A.H

      Therefore we need about 8000A.H so as we can get approximately continuous power of 5kv for 12 hours with inverter of 5kv with efficiency of 60%.

      2.Size of panel required
      Since we need to replace 625 Ampere after every one hour which means we need to replace 7500Ampere for 12 hours.

      Since solar panels they can provide full power only during full sun where in tropical region we have approximately of 8hours of full sun therefore the size of the panel will be

      The panel should be able to deliver 950 Ampere per hour which is equal to
      7600 Ampere for 8 Hours

      Now the power of panel require is
      Power=Current x Voltage
      Power=950 x 17.8=16910 approximately 17000 Wattage

      Therefore the solar panel required is
      17000 Wattage
      17.8 Voltage
      950 Ampere

      3.Control Charger required
      12 Voltage
      950 Ampere

      REQUIREMENTS

      EQUIPMENTS POWER/SIZE COST
      Inverter

      5KV
      12V
      Solar Panels

      17000 Wattage
      17.8 Voltage
      950 Ampere
      Charger Control

      12 Voltage
      950 Ampere
      Parallel connected Batteries 8000 A.H
      (You can divide with any number of battery Ah) For example if you have 1000 A.H battery

      8000 A.H/1000A.H=8 batteries of 1000 A.H are needed and so on.
      Which will be connected parallel

      hiyo power rating ya kv=kW unamaanisha kVA=kW au hiyo kV ni model za hizo inverter ambayo inaonyesha power rating ya inverter yenyewe na sio voltage rating
