Micro Power Grid & Equipment Pay-Back Calculator. 

 Enter your Energy Consumption & the Retail Rate; (kWh Rate needed to calculate savings, based on Self Consumption)

Peak-Energy & Rate ? 
Shoulder-Energy & Rate ? 
Off-Peak-Energy & Rate ? 
 Retailer Daily Supply Charge ? 
$  =  $ Quarterly Grid Supply Charge.   
State Grid Electricity COST: 
                excludes GST.

 Calculate your Equipment & Generation Cost; (#Below equipment costs are set @$0.75 exchange rate)

# Solar/Hybrid Inverter ? 

 NB: Solar ONLY Inverters DO NOT charge Batteries!

# Solar Panels ? 

# Select Your Solar Racking Type ?

*TOTAL System EXCESS Energy:

kWh Year     $

 Excess Energy field MUST be Positive, if not, increase Solar or other Energy production, more Energy production reduces the break-even period quicker !

 *Enter the Energy you could sell via P2P Energy Trading:

 kWh Year     $

In the Red P2P field above, Enter no more than is in the System Excess Energy field, this will deduct the kWh from System Excess Energy field.

 NB: You must have Battery Storage, to be able to On-sell energy to a Bespoke Retailer !

TOTAL System Cost: $ Calculate Equipment cost at Exchange rate!
Total Yearly Power Production Cost: $ NB: Battery storage is required to Self-consume all your generated energy.
Payback Time:  Before profit, includes System cost, less any Rebates, Credits & Fuel cost.
TOTAL Yearly Savings/Income: $ After the break-even period, includes Solar savings, Feed-in and Harvest Credits.

Will your electricity savings pay for Financing your Micro Power Grid ?

YES, if you add a year to the 'PayBack time' and $1'000 for installation, your Monthly repayment should be less then your Power bill !

The larger your Battery storage the more secure and less chance of you having a black-out.

# Approx. product costs to become totally independent of the state grid.

* Only if more power is generated than consumed, this calculator will reduce your Payback Time further !
