  Solar Calculator advice -  How to use the system  
 
1 Only Update after you completed everything, you can switch between pages without updating
2 At the end the KWH value you get should be more or less the same as per your monthly W&L quantity
3 If the prices seem high at first, play with your Power energy calculations  
4 See what affect it have if you :  
  a Reduce timing on your Geyser (add a geyser timer)  
  b Reduce timing on your Swimming pool pump (4 hours)  
  c Replace lights with energy Efficient lights  
  d Replace the stove with Gas  
  e Have a Gas Geyser  
  f take out power items such as underfloor heating  
  g Replace security lights with low power energy efficient lights  
  h Use better Fridge/Freezers AA rating of which total daily power is only 700W.h  
5 Remember you do not need to START with a full system, you can start small and build up  
6 Please also remember products used are the Best most reliable in the field from Europe and USA

NB: Fill in only the quantities of what is applicable to you,acording to rating of applaince  
  If you are unsure look at the Manufacturer's plate, on the side or back of applaince   Your sheet will be e-mailed to you when you Update  
  Sometimes the Watt Rating is not there, only the  VA- then fill in VA under Watt  
  If neither the Watt Nor VA is present, then fill in the Amp and Volt Rating   
  Otherwise Leave   Amp and Volt rating empty        
  Choose estimated Hours per day , i.e. 15 Minutes = 0.25 Hours , 30 Minutes = 0.5 Hours  
  ONLY FILL IN THE APPLIANCES WHICH YOU NEED/WANT  TO RUN ON THE SYSTEM
