Fixed Tilted Solar Racking v Single & Dual Axis Racking

Flat & Fixed Tilted Solar Racking is the least efficient at Generating Energy, where DAT Solar Racking is Superior at Generating Energy!

Change the Panel size & Racking type to suit your Latitude Location !

NB: Only the RED cells can be changed, currently set for a 3.0kWh/p DAT Solar Array in Sydney.

 1) Solar Energy Generation ::

Enter Solar Panel Quantity:


 Add additional panels to increase System kWh.
 Select the Solar Panel Power:
 Select Solar Racking/Harvesting Type:

 For accurate calculation, solar modules effected by Shading from trees, buildings or terrain, reduce the hours of Harvesting! 

 Total System Energy Generated:

kWh/p DC Energy Generated per Day.

 Above Fields indicate approx. Energy production, other factors can change these results. 

 2) Small-scale Technology Certificates (STC) ::

 Number of years STC/REC's are Claimed: 

 Max 11 Years from Jan 2020. (set to end in 2030) 

 Click Here to Calculate YOUR System STC Quantity NB: 1x STC = 1x REC credit, and are limited to a maximum 100kWh system.

Now Enter your system STC's: 

 STC Credits. 

  (1 STC = 1 REC)  

 (Default STC's is set to a 3.6KW Solar system)

 *Renewal Energy Certificate (REC) Price: 

$ per REC.  

  System TOTAL REC's Refund/Credit: $

 Calculate the Government STC/REC Price, by setting the above to the current Market price.

 *Approx. REC spot prices fell to $35 in 2019.

 3) System Generation, Consumption & Feed-in Tarrif or P2P Income ::

Daily Solar Energy Generated:


 Daily Energy CONSUMPTION:

 kWh per Day.   Change this figure to match your actual energy Consumption ! 

 *System DAILY EXCESS Energy:


Feed-In-Tarrif or P2P Income Rate:

  $   $ 

 Excess Energy field MUST be Positive, if not increase Solar Harvesting or reduce Consumption, and the more Energy Generated reduces the break-even period if Grid connected !

4) Enter Your RETAILER Energy Rate ::

            Enter your current Retail Energy Rate: 

$  per kWh 

 Even if you are Off-Grid, Change the above Retailer Rate to your area, as it will indicate what you are Saving!

 5) Income from P2P Trading or Feed-in-Tarrif ::



 per kWh 



 per Day 



 per Week 



 per Month 



 per Year 

$ $ $ $ $

 Only if you are connected to the State Grid supply or Private distribution.

 6) Micro Grid - Payback time ::

 Enter TOTAL System Investment Cost: 

$ You can use this field to include the cost of Solar, Wind & Batteries etc.


$ REC's are Paid in one lump-sum amount into Your bank account after CEC approval.

 *Yearly Self-Consumption SAVINGS: 

$ ONLY applies if you Consume some of your Solar energy, as set above!

 *Yearly Feed-in-Tarrif or P2P INCOME: 

$ ONLY applies if State Grid connected and Exporting at the Rate You set above.

*Years to Break-Even Point: 

 Years  Based on above figures you enter!

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), Fixed panels, Single Axis 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!
