Our Team Provided forms with specific questions to be answered by the installers. This allowed us to compare proposals apples to apples. It was a lot of work for our installers but the ones selected rose to the challenge.
Here is a summary of their Proposal
Our selected installer is Solaflect http://www.solaflect.com
Although tracking systems were not part of our original request for proposals, we received a proposal from Solaflec that was too good to not include in our program. Their unique tracking device is sold at a cost equal to or better than fixed units if you consider the added 30% efficiency.
Base Price $4.80 however these systems are expected to deliver 30-40% more electricity for the same wattage of panel. For comparison, a 30% efficiency gain calculates to equivalent $3.69/w
Tiered Price per Watt based upon number of trackers sold by Solaflect in our program
Tier 1 <32Kw (up to 7 trackers)= $4.80
Tier 2 32-<64Kw (8 to 15 trackers)= $4.75
Tier 3 64- <96 (16-23 trackers)= $4.70
Tier 4 96-<128Kw (24-31 trackers)= $4.65
Tier 5 128-<160 Kw (32-39 trackers)= $4.60
Tier 6 160Kw+ (40 +trackers)= $4.55
System warranty is for 10 years but requires annual maintenance to be performed each year (analogous to a boiler tune up)
Annual maintenance is free for the first 3 years, $125/year after that.
you can purchase these in 4KW increments only(a complete tracker) 4Kw, 8Kw, 12Kw etc.
Price adders Include
Extra Ground Trenching – In the event the wire and conduit run for a ground mounted system from 201 feet to 275 feet there will be an additional charge of $4/foot for each foot beyond 200 feet. $5/foot plus $300 beyond 275 feet .
Electrical Upgrades – case by case if required
