Existing Solar Return On Investment (RIO) Calculator:

How long will it take to Pay for a Battery Bank using your Existing Solar array ?

To calculate that, enter your Solar Array Size, Racking Type to the Nearest City latitude.

Use your most expensive power bill and Adjust the Equipment to see the investment payback time!

TOTAL System Energy PRODUCED:

TOTAL System Energy CONSUMPTION:

*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:

$ Above Equipment is Calculate at cost of Exchange rate!

Total Yearly Power Production Cost:

$ NB: Energy 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 Energy 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 !
