Transcript of Solar Photovoltaics and The Feed In Tariff

  • Solar Photovoltaics and The Feed In Tariff

  • Company based in Brantford.Dan Cole - Owner and Manager.Mike Triska Engineering and Energy Audits.Installation crew of 4 headed up by our master electrician with 6 yrs experience in PV and small wind.

  • A brief overview of solar energy is required in order to make sure the over all concept of todays presentation is understood

  • Solar EnergySolar energy is a renewable resource that is free, readily available, environmentally friendly and necessary for all life on earth. Solar energy can be used in many ways - to provide heat, lighting, mechanical power and electricity, which is what we are focusing on here today.

  • Photovoltaics (PV)

    dc electricity is generated from sunlight by using photovoltaic (PV) solar cells.

  • These cells are semiconductor devices, usually made of silicon, which contain no liquids, corrosive chemicals or moving parts. The PV panels require little maintenance, do not pollute, and operate silently, making photovoltaic energy a very clean and safe method of power generation.

  • TYPES OF SOLAR CELLS

  • MONOCRYSTALINE CELLS:High quality starting material (same a computer chips)Highest cell efficiency (14% to 17%)Most expensiveOriginal type of PV cellDepends on direct sunlight (not so good on cloudy days)Most sensitive to heat

  • POLYCRYSTALINE CELLS:Most common typecell efficiency 13% to 15%Less expensive to manufacture than monoLess temperature sensitive

  • THIN FILM CELLS:Thin layers vacuum evaporated onto glassCell efficiency currently 5% to 8%New technologySilicon and other materials (e.g. first solar CIGS)Less sensitive to temperatureWorks better in indirect light than crystalline cellsPotentially much cheaper

  • Using an Inverter, the DC electricity from the Solar PV is converted to AC, then its fed through a meter, in the case of FIT, to measure the amount produced, and then it is all sold to the grid.

  • TYPICAL GRID CONNECTION(FROM ESA-SPEC-004)

  • TYPICAL GRID-TIE INVERTER SPECIFICATIONS(From SMA)

  • ANTI-ISLANDING PROTECTION(UL 1741, IEEE 1547, CSA C22.2 No. 107.1 STANDARDS) Grid-tied inverters that meet the above standards will shut off if they do not detect the presence of the utility grid to prevent and IslandAn inverter designed for grid-tie operation will have anti-islanding protection built in; it will inject small pulses that are slightly out of phase with the AC electrical system in order to cancel any stray resonances that may be present when the grid shuts down. Required by ESA-SPEC-004

  • This brings us to the question

  • What is a Feed in Tariff?Basic terms you generate renewable electricity, the Ontario Power Authority buys it from you through your Local Distribution Company.

  • Ontario's feed-in tariff is North America's first comprehensive guaranteed pricing structure for renewable electricity production. It offers stableprices under a long-term 20 yr contract.

  • The FIT Program was enabled bythe Green Energy and Green Economy Act, 2009 which was passed into law on May 14, 2009. The Ontario Power Authority is responsible for implementing the program.FIT came online the end of September 2009.There have been over 21,000 applications submitted and 14,000 approvals and 1,800 contracts offered. 99% of these are for Solar PV.

  • Goals of FIThelp Ontariophase out coal-fired electricityhelp replace generating capacity from soon to be retired nuclear plants boost economic activity and the development of renewable energy technologies create green industries and jobs.

  • The program is divided into two streams - FIT and microFIT. The FIT Program is for renewable energy projects over 10kW, any projects under 10kW are classed as Micro FIT.

  • The made-in-Ontario FIT Program combines lessons learned from FIT programs in Germany, Spain, Denmark.Canada is far behind many other countries in the deployment of renewable energy

  • FIT and MICRO-FIT PRICE SCHEDULE SOLAR PV(From: http://fit.powerauthority.on.ca/Page.asp?PageID=924&ContentID=10543)(AS OF 13 AUG 2010)

  • What is required to participate? Proper location is critical.Rule # 1- stick it where the sun shines!For every kW of PV we need 100 sq feet (10 X10) of south facing sloped roof or 200 sq ft (10 X 20) of flat roof

  • unobstructed by trees or any other obstacles that cast a shadow Ground mounted on racks at a 30 to 50 degree angle, unobstructed by trees or other obstacles that cast a shadow.

  • Access to the grid is required to sell your green electricity.Thats rule # 2- plug it in and get paid for it!

  • So, lets assume someone is interested in getting paid to help save the planet with a south facing roof of 1000sq ft.

  • What is the cost?Micro-FITPrice range for 10kw system is between $7.50-$10.00 per watt installed, and connected to the grid.Includes site assessment, design, applications, permits, inspections, installation and connection turnkey solution.Assessment includes a RETScreen Analysis.

  • RETScreen

    Renewable-energy and Energy-efficient Technologies (RETs)

  • OverviewThe RETScreen Clean Energy Project Analysis Software is the worlds leading clean energy decision-making software. It is provided by the Government of Canada as part of Canadas recognition of the need to take an integrated approach in addressing climate change and reducing pollution. RETScreen is a proven enabler of clean energy projects worldwide.

  • RETScreen allows decision-makers and professionals to determine whether or not a proposed renewable energy project makes financial sense. If a project is viableor if it is notRETScreen will help the decision-maker understand this: quickly, unequivocally, in a user-friendly format, and at relatively minimal cost.

  • EXAMPLE RETScreen ANALYSIS

  • We know the basicswhat PV is and how it works, what a feed in tariff is and how it works, the legislation behind the program,what kind of site we need, rules 1 and 2,how much a system will cost,how much electricity we will produce

  • What about the $GREEN ?

  • Price SchedulesMicro FIT-
  • Example 9.72kW system(Micro- FIT)

    Initial cost is around $75,000.00-85,000.00100% financed at 5%-6% mortgaged over 11 yearsSystem generates approximately 11.5-12 MWh of green electricity per year$9,000.00-$10,000.00 per year in revenue dependant on the site.Payback is about 8-10 years, dependant on financing, exact initial cost, etc.Remaining 10-12 years of 20 year contract is profit.ROI between 10-13%Emission reduction of NEGATIVE 11 tonnes of CO2 per year

  • MicroFIT Project Timeline

  • Each 10 kW system equalsnegative 11 tCO2-11 tonnes of CO2 is equivalent to :9 acres of carbon absorbing forest.2.2 cars or light trucks taken off the road4,310 litres of gasoline not consumed22 barrels of crude oil not consumed10.6 people reducing their energy consumption by 20%.

  • Just Think.What if we had 10 of these systems-110 tcO2115-120 MW of GREEN electricity equals90 acres of forest22 cars or light trucks off the road43,100 litres of gasoline not consumed220 barrels of crude oil not consumed106 people reducing their energy consumption by 20%.

  • Summary

    By promoting the use of renewable energy to produce clean electricity, we are able to generate income, reduce harmful emissions and create jobs. By coming together as a community we will enable individual non-profit organizations to achieve these goals more easily and sooner.
