SA Power Outage in 2016

1MW (1'000KW) Community Solar Farm Investment Time-frame.


  1. Flat & Fixed Tilted Solar Panel Racking is the least efficient at Harvesting Energy.
  2. DAT & SAT Solar Tracking Racking is the BEST at Harvesting Energy.

Change the Panel Watts, Array Racking and Latitude Location for better accuracy of this calculator!

This calculator does not allow for inverter, transition or parasitic losses.

NB: Only the RED cells can be changed, currently set for a 1MW Solar Farm.

 :: Energy HARVESTING potential of 1MW (1'000kWh) Solar Array ::

Enter Solar Panel Quantity:


 Add additional panels to compensate, if you have Wind/Aqua energy installed.

 Solar Racking & Harvesting:

 For a more accurate Harvesting calculation, Solar system effected by Shading from trees, buildings or terrain, Reduce the hours of Harvesting! 

Total Energy Harvested:

 :: Australian Commercial Energy Rate ::

 December 2019 commercial energy rates;

 Enter your current Commercial Energy Rate: 

 Change the Commercial Energy Rate to your average rate!

$ per kWh 

  • $0.08 kWh for Peak energy rate.
  • $0.05 kWh for Shoulder energy rate.
  • $0.03 kWh for Off-peak energy rate.

 It's NOT a mistake, the above is set to what large commercial consumers pay in Sydney.

 Plus the other misleading fees Energy Retailers charge, as Retailers Only compete to make a profit on your Energy consumption!

 Energy Generators are way better selling there energy via Power Ledger, an Australian company linked into the local energy Distributor!

 :: Large-scale Generation Certificates (LGC) ::

 Read more Information on Large-scale Generation Certificates (LGC) Market Price

 NB: STC (REC credits) are limited to maximum 100kWh system.

 Number of years LGC's are Claimed:

 Max 11 Years(set to end in 2030) 

*Large-scale Technology Certificates:

 STC Credits. 

  (1 STC = 1 REC)  

 *2020 LGC Certificate Price:

$ per REC.  

  TOTAL System LGC's Refund/Credit: $

 *Change the LGC Certificates Price above to the current offer Market rates.

 LGC Rate is set to $24.40MWh in 2020, and possibly $14.25MWh for 2021.

 :: Micro Power Grid - Potential Payback time ::

 Enter your System's TOTAL Investment Cost:

$ This cost can include Solar, Wind & Batteries etc.

Approx. Yearly Savings/Income:

$ If consumption of all Solar energy at above Energy Rate.

*Approx. Yearly REC/LGC:

$ 1 STC =1 REC =1 LGC at above set rate.

Years to Break-Even Period:

 Years  Based on figures entered above.

Solar Farm Capital Expense:

$per Watt  Based on Total cost ÷ by system kWh.

 Change any of the above RED Fields to see the Investment Payback Time!


Important: Please note that all amounts and estimates shown above can be set to suit multiple configurations, and are used for symbolic estimation purpose only.  The actual figure depends on lots of issues including quantity of sun (cloud coverage), single or dual axis tracking, cabling (DC/AC), electrical connections and electronic losses etc.  These amounts and figures should be considered as example only, and under whatever circumstances, we do not make any guarantee, or cannot be held responsible about these estimates, if used as an actual return to investment!
