5MW Solar Farm Energy Harvesting & PayBack Calculator

Change the Panel Watts, Array Racking to your nearest Latitude Location for better Generation accuracy!

NB: Only the RED cells can be changed, currently set for a 5MW solar farm.

 1) Solar Farm Energy GENERATION; 

Enter Solar Panel Quantity:


 Installing 590W panels requires 8'475 panels.
Solar Panel Power:



   *Total Solar Panel Cost: $
 Solar Racking & Generation Hours:

 For accurate calculation, if solar array is effected by Shading from trees, buildings or terrain, reduce the hours of Harvesting.

 Total Solar Energy Generated:

MW/p energy per Day.    

kWh/p energy per Day

 Solar Array Size 

per Hour/peak

 Energy Harvested 

per Day/peak

 Energy Harvested 

per Week/peak

 Energy Harvested 

per Month/peak

 Energy Harvested 

per Quarter/peak

 Energy Harvested 

per Year/peak

 Above Fields indicate Peak Energy Generation, bad-weather and transmission-losses & PPA's can reduce these results!

 2) Large-scale Generation Certificates (LGC);

 4) SOLAR FARM - Potential Payback time;

 The Solar Farm's Total Upfront Investment Cost: 

$ Enter Solar Farm Total Cost. (*LOC: $1'700'000MW)

Approx. Yearly LGC: 

$ Calculated on Large-scale Generation Certificate Rate set above.

Approx. Yearly Spot Market Income: 

$ Calculated on the Electricity Spot Market Price set above.

Years to Break-Even Period: 

Years  Based on figures entered above.

Solar Farm Investment Expense: 

$per kWh   =Total Cost ÷ 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), 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 on investment!

Use the above calculator to evaluate the kWh array type and size you require, DAT is superior at Energy Generation than any other Racking type.

Below Module Racking options are commonly used in Solar Farm's !

DAT-15 module holds 15x 380W panel Array =5.7kWh peak DC energy.

DAT-15 module holds 15x 435W panel Array =6.5kWh peak DC energy.

DAT-24 module holds 24x 380W panel Array =9.1kWh peak DC energy.

DAT-24 module holds 24x 435W panel Array =10.4kWh peak DC energy.

SAT holds 60x 6 Rows, 380W panel Array (image) =137kWh/p peak DC energy.
