MicroFIT Return On Investment (ROI)

How will the new microFIT program benefit me?
 

Sample Calculation 1

  

$18,275 installed fixed sloped roof residential 4.3 kW rated Grid Tie Solar PV system based on an annual average of 1200 kWh/kW of solar PV (source: RETScreen; Natural Resources Canada);

  1. 1. 4.3 kW x .9 (10% de-rate factor)* = 3.9 kW
  2. 2. 3.9 kW x 1200 kWh/kW = 4,680 kWh/yr.
  3. 3. 4,680 kWh/yr. x 54.9 cents/kWh** = $2,569 annual income ($214 average per month). 

 

Return On Investment (ROI) and Payback;


  1. 1. $18,275 investment / $2,569 annual income = 7.1 years Payback !
  2. 2. $2,569 / $18,275 = 0.14 or 14% ROI !
  3. 3. Installed system cost: $4.25 per watt + HST (Can be less depending on market prices).
  4. 4. Net Present Value (NPV) at the completion of the 20 year microFIT contract: $33,105 equity.

 

 

Sample Calculation 2

 

$69,900 installed dual tracker system 11.75 kW*** rated Grid Tie Solar PV system based on an annual average of 1680 kWh/kW of solar PV (Source: RETScreen; Natural Resources Canada);

  1. 1. 11.75 kW x .9 (10% de-rate factor)* = 10.6 kW
  2. 2. 10.6 kW x 1680 kWh = 17,808 kWh per year
  3. 3. 17,808 kWh/yr. x 44.5 cents/kWh** = $7,925 annual income ($660 average per month).

 

Return On Investment (ROI) and Payback;


  1. 1. $69,900 investment / $7,925 annual income = 8.8 years Payback !
  2. 2. $7,925 / $69,900 = 0.11 or 11% ROI !
  3. 3. Installed system cost: $5.95 per watt + HST (Can be less depending on market prices).
  4. 4. Net Present Value (NPV) at the completion of the 20 year microFIT contract: $88,591 equity.

 

* De-rate factor compensates for system inefficiencies, non peak operation and module degradation.

** Rooftop and ground mount microFIT incentive rates for 2012.

*** Solar array size with inverter nameplate rating of 10 kW for MicroFIT eligibility.
