2x DART-15 Dual Axis-solar Radiation Tracking Racking v Fixed Tilted Racking

Fixed Tilted Solar Racking is inferior at Generating Energy than DART Solar Racking !

700W, Double Glazed, Bi-facial, Shingled, Monocrysteline Solar Panels can be supplied.

CHANGE this calculator to suit your Panel Wattage, Racking type & Your Latitude Location !

If looking to be Off-Grid Remove the STC Credits, then the Rebate cell will show the Saving based on the Retail Power Rate.

NB: Only the RED cells can be changed.

 1) Energy Generation;

 Enter Solar Panel Quantity:

 Solar Panels. 

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


$ Watt. 

   *Total Solar Panel Cost: $
 Select Solar Racking Type:

 For accurate calculation, solar panels effected by Shading from trees, buildings or terrain, simply reduce the hours of Generation! 

 Systems Energy Generated:

kWh/p DC Energy per Day. 


Array Size

 per Hour/peak 

Solar Energy


 per Day/peak

 per Year/peak 

 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: 

 STC's set to End in January 2030.

 NB: STC credits are limited to a maximum 100kW system. Click Here to Calculate YOUR own System STC Quantity

 Delete if Not involved or Enter system STC's: 

 STC Credits. 

 (Pre-set to a 21kW Solar Array using 700W Panels)

 *Small-scale Technology Certificate (STC) Price: 

$ per STC.  

  Systems STC's to be Paid: $

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

 STC are for Arrays under a 100kW, REC are for Larger Generators & Paid quarterly, compared to a One off payment for STC.

 3) System Generation, Consumption & Feed-In Tariff or P2P Income;

Daily Solar Energy Generated:


 Enter Your Daily Energy CONSUMPTION:

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

 *System DAILY EXCESS Energy:


Feed-In Tariff or P2P Income Rate:

  $   $ 

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

 4) Enter Your RETAILER Energy Rate;

 Change to your local Retailer Energy Rate: 

$  per kWh (Red Energy $0.26kWh April 2023) 

 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 Power!

 5) System Income from P2P Energy Trading or Feed-in-Tarrif;


 per kW 


 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;

*Estimated Equipment Cost: 

$ 2x DART-15, Solar Panels, Inverter, Conduit, Cabling, Fittings & Concrete.

 *Estimated TOTAL Installation Cost: 

$ Labour: 2x DART @$5'000each =$10k, +Trenching etc. Self Installation = Big Savings !

*STC Payment if Claimed: 

$ STC's are Paid in one lump-sum amount, 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 kW   OR  $ per Watt  =Total System Cost - less STC's Refund ÷ by system kW.

Solar Levelised Cost of Energy LCOE: 

$per kW  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 kW 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!
