Solar Roof System
MicroFIT What is it?
It is Ontario’s answer to clean power production for a fee, a fee that is paid directly to you
OPA will buy the electricity you generate at $0.549/KW if your solar array is roof mounted or $0.445/KW if it is ground mounted
The system can be as large as 10KW (40-52 panels) or smaller if your roof area doesn’t allow it
Once you sign the microFIT contract with OPA, your rate is guaranteed for 20 years
For example, If you have a 10KW setup on your roof, then this system will make on average (pending
site assessment) $8,015.4/year. Multiply that by 20 years and you could make up to $160,308
Once we have taken a few measurements from your home we can create a 3D model and lay the solar panels on the roof, then simulate Sun paths and observe shadows for optimum placement, calculate the amount power the setup can generate and dollars
it will produce for you every year, while taking into account how Financing options and TAX's would change the total income and what your Return On Investment (ROI) will be.
Solar 101
Energy from the Sun
Earth receives a HUGE amount of solar radiation every day. About 30% of it is reflected back to space, the rest falls on clouds, land and the oceans. Solar
radiation (sunlight) is used in generating electricity. Solar power is the conversion of sunlight into electricity using photovoltaics (PV), PV converts
light into electric current using the photoelectric effect.
Next the Direct
Current (DC) that is generated by the PV
panels is converted to Alternating
Current (AC) by means of an inverter so it can be connected and fed back to the utility lines.
For a microFIT subscriber the generated power is measured by means of a standard meter and the total power generated is paid at the end of each month.
In Ontario (44 degrees) sunlight average is about 3~4 hours per day per year, that means (lets pick 3 hours), 3 x 365 = 1,095 hours of sunlight.
If you have 1,250W panel say from "Canadian Solar", that would mean 1,095h x 250W = 273,750W or 273.750KW of power in 1 year.
microFIT allows up to a one 10KW system, which means 10,000W/250=40 panels (250W each and installed on a dual axis tracker for optimum production).
Therefore 273,750W x 40= 10,950,000 W or 10.950MW of power / Year in Ontario.
Multiply this by $0.549/KWh (for roof mount) 10,950KWh = $6,011.55 per year in your pocket.
Now we know from experience that the amount of sunlight on average is more in ontario based on data from various certified installations, which for a 10KW system result in more dollares than the above calculation.

Figure 1: This 3D model shows solar panels placed on the roof and shows the location of
the vents.
Figure 2: Shows early morning Sun on 1-JAN-2011, shadows are long and we can see they
fall on some of the panels.
Figure 3: Not only we can look more closely at different parts of the installtion in 3D...
Figure 4: We can also analyze the overall yearly solar exposure and decide if it makes
sense to place the panels in a specific area or not.
Here green indicates total exposure and red little or none.
Since we have room to move the top row to the left, we can gain more of the sun light
and generate more power. Simulation shows this before installation and saves time and money.
Figure 5: Compare this and figure 4. by moving the top row panels to the left, we
managed to improve power generation 4.6% and 12% from left to right.
