10. Introduction to Solar Technology
Photovoltaic Electricity is a process whereby sunlight is converted directly into direct current
(DC) electricity in a solar cell that is typically based on Silicon. Solar cells are manufactured into
solar modules, which are then constructed into arrays. Solar arrays feed direct current electricity
to an inverter that connects the array to the utility grid via the building’s electrical system.
Solar arrays are commonly located on building rooftops and they are ideal for integration into
building designs, where multiple benefits may be attained through solar Photovoltaic deployment,
such as integration with day lighting strategies. Solar Energy is the most reliable electricity
source available and the Operations & Maintenance costs are negligible as compared with all
other electrical generation systems.

11. Life Expectancy
Service life estimate of photovoltaic arrays is generally taken to be 30 years, although they will
continue to operate well beyond. Outright failure is rare, even at extreme age; it is the degradation
of power generation that renders the products less usable over time. Annual output reduction is in
the order of 0.5 to 0.75%.
The Photovoltaic modules generally carry warranties of 25 years and the power inverters are
generally warranted at 10 years, with available warranty extensions that can be purchased at time
of system order.
Since there are no moving parts, solar Photovoltaic systems are not subject to wear and tear as
would be typically associated with other types of generation systems.
photovoltaic modules can be recycled at the end of their useful life.

12. Photovoltaic Electricity Overview
Photovoltaic modules employ layers of micro-fine crystalline silicon to convert ordinary
sunlight into small electrical charges. To explain the photovoltaic solar panel more
simply, photons from sunlight knock electrons into a higher state of energy, creating
electricity. The term photovoltaic refers a photodiode in which current through the
device is generated by light energy. Virtually all photovoltaic devices are some type of
photodiode. Solar cells produce direct current electricity from light, which can be used
to power equipment or distribute to the electrical grid.
Solar photovoltaic power systems are categorized into three types.
 Autonomous Power Systems - non-electrified areas
 Hybrid Power Systems - wind, solar, hydro, etc.
Grid-Connected Power Systems
– Static / Adjustable Ground/Rooftop Mounted Arrays
– Single-Axis Horizontal Tracking Arrays
– Dual-Axis Tracking Arrays

13. Photovoltaic Efficiency
Photovoltaic systems operate by collecting daylight, both direct sunlight and diffuse daylight, and
across a broad light spectrum. For our purposes, regarding deployment on this property, efficiency is
probably best considered as being the power able to be generated (in rated peak kilowatts) in a given
amount of space. Operationally, the electrical energy yield of Photovoltaic will vary depending on numerous
factors including ambient and solar cell temperature, tilt angle, ventilation and shading from obstructions,
etc.
Careful project design is imperative in order to attain optimum operational efficiency.

14. Benefits of Solar Photovoltaic Energy
Solar Systems offer many advantages:
 Clean, efficient, safe, and sustainable
 Highly reliable and operate cost-effectively
 Require little maintenance, when compared to other generation sources
 They are flexible and can be expanded at any time
 Requires little lead time, solar facilities can be up and operational in under a year
 No additional fuel cost
 Operating expectancy of 25 to 30 years

15. Environmental Benefits
Photovoltaic systems can significantly reduce the carbon footprint of
businesses and cities.
Greenhouse gas emissions reductions can be calculated as greater than the
offset created merely by the generation of electricity. 1kW of electricity represents
approximately 250 tonnes of CO2 offset over the life of the system, depending on the
final nameplate rating chosen.
For example, a proposed photovoltaic project size stated at 250 kilowatt peak will
provide for approximately 62,500 tonnes of CO2 offset over the life of the system,
depending on the final nameplate rating chosen.

16. Energy Payback
Typical silicon solar Photovoltaic modules will achieve an energy break-even in 3-4 years. The
total embodied energy in the product from its manufacture will be returned about 10 times over
its operational life. An important goal in the design of a photovoltaic project is to optimize the
ancillary systems required to mount the solar modules to the building so as to maintain the
greatest net energy return.
The energy payback time for a well-designed Photovoltaic system today can be in the range of
6 to 9 years.

27. Ontario Power Authority (OPA)
(FIT) Feed In Tarrif Program
Ontario was the first jurisdiction in North America to adopt a European styled program to stimulate
investment in photovoltaic installations and other renewable generation technologies including wind.
This program provides for the signing of a 20 year contract with the Government of Ontario, whereby the
contract guarantees a fixed amount payable per kilowatt-hour generated from the renewable energy project.
Controlled and paid by the Ontario Power Authority.
With the advent of the program, the economics of a commercial photovoltaic system purchase in Ontario
have been improved by a factor of four.
Proposed OPA’s FIT rates for Photovoltaic Electricity production
≤ 10kW @ 80.2 cents /kWh 10 - 250kW @ 71.3 250 - 500kW @ 63.5 ≥ 500 kW @ 53.9
Ground mounted field applications ≤ 10MW @ 44.3 cents per kWh

28. Project Payback
While photovoltaic systems have a significant capital cost, they offer negligible operating costs as well as
potential savings in building or brown field costs depending on how they are deployed. It is important to
understand that, as compared to buying electricity from traditional sources, the capital cost of a photovoltaic
system inherently includes 30 years of electricity cost savings.
Return On Investment with large commercial photovoltaic installations is nearing the 6-9 year timeframe,
taking into account available Federal and Provincial programs and incentives.
Paybacks can be improved further by designing the photovoltaic system to optimize client’s financial goals
and to facilitate either building or brown field integration of such power systems.

33. Federal Capital Cost Allowance Acceleration
The Federal Capital Cost Allowance Acceleration (CCA)
The tax act includes Class 43.2, Schedule II that allows photovoltaic generating assets
to be written off at an accelerate rate of 50% per annum (declining balance calculation
method), thereby serving to speed the time to photovoltaic project breakeven.
