    Installation cost estimates?

    Hello,

    I have been getting estimates from various suppliers for supply and installation of solar PV systems, grid tie, in Ontario for the FIT program. The exected project size is about 200kw. Typical prices have been around the $7 per watt range. I have had an estimate from another company affiliated with a US wholesale distributor who is giving me a price of $4.11 per watt, not including installation.

    I currently operate a company and have my own electrician and work with commercial electricians every day, so I am sure I could line one up. I also have a crew that would be able to handle the installation.

    Does anyone have any way to estimate installation costs for a system? It would be about 200kw, roof mounted on a sloped poultry barn roof, standing seam penetrated.

    200KW is a major install, you may need a special letter from the utility company.

    And I believe there are "clamps" that grip a standing seam roof, without drilling holes into it.

      There is a Feed in Tariff program in Ontario that I would be connecting under. I have a meeting with the utility company next week to discuss the tie in.

      I would be interested in standing seam installation that does not require penetration.

      I should have mentioned that the 'package' includes panels, racking/mounting system, inverters, array wiring and hardware, AC/DC disconnects, solar string combiners, and design services.

      I would be responsible for materials and installation of wiring from string combiners to inverter and inverter to meter, as well as grounding.

      At this point it is feasibility, so I am looking for rough estimates of man hours for electrician and installation (mounting) crew.

        Well I am not sure about Canadian laws but are you including a PE fee of about 10%

          10% for the PE? A bit on the high side?

            No that is pretty standard rate for design/build cost plus 10%. Lot cheaper than a builder would charge you for less quality.

              We do this sort of work -- turn-key of 100kW to 250kW projects on industrial and agricultural properties -- and an engineering fee of $25k to $45k is normal. Much of it is driven by the documentation requirements of the municipality for building permits.

              You should be getting a quote for equipment and services, all in, of $5.00 - $5.25 per watt. If not, we would like to bid on your project.

              As for your standing seam question: we use S5 clamps for this -- which mitigates the need for penetrations.

              Would be happy to discuss this project with you, even to just answer some of your questions. 416-907-6618. Cameron at Endura Energy (www.enduraenergy.ca)
