1x DAT-8 Dual Axis Solar Racking v Fixed Tilted Racking

Flat & Fixed Tilted Solar Racking is inferior 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 3.52kWh/p DAT Solar Array in Sydney.

 1) Energy Generation;

Enter Solar Panel Quantity:


 Add additional panels to increase System kWh.
 Select the Solar Panel Power:


$ Watt. 

   *Total Solar Panel Cost: $
 Select Solar Racking/Generation 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 peak Energy production, other transmission losses reduce these results.

 2) Claiming Small-scale Technology Certificates (STC);

 Standard Government Deeming Period for STC's: 

 10 Years STC's from Jan 2021. (set to end in 2030) 

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

Delete if Not involved or Enter your system STC's: 

 STC/REC Credits. 

 (Pre-set to a 3.48kW Solar Array)

 *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:


 Enter your Daily Energy CONSUMPTION:

 kWh per Day.   If any, 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 local Retail Energy Rate: 

$  per kWh 

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

 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 - Investment Payback time;

 Enter TOTAL System Investment Cost: 

$ DATs, Solar Panels and Cabling cost.

 Enter Estimated TOTAL Installation Cost: 

$ You will make big Savings if you do some or all of the installation yourself.


$ 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 Array Capital Expense: 

$per kWh   OR  $ per Watt  =Total System Cost - less REC's Refund ÷ by system kWh.

Solar Levelised Cost of Energy LCOE: 

$per kWh  LCOE =Total System Cost ÷ 25 year energy Generation.

 LCOE is Calculated on the system's total out of pocket Cost inc. O&M ÷ 25 years kWh Generation. (25 years assumed lifetime)

 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!
