I have a 10 year old ground mount solar array. It is a 10k unit. It was the max that they would let my father do 10 years ago. He is putting up a new bigger array. It was bought outright never a lease. Below are the specs.$ 20k obro they we're over $40k new
Please find attached the specifications sheets for the quantity: 40 solar modules (SolarWorld Sunmodule SW 295 Mono) and quantity: 40 Enphase microinverters (Enphase M250 microinverters), with quantity: 42 Enphase Engage cable drops (there are two branches/chains of 11 drops/microinverter connections, and two branches/chains of 10 drops/microinverter connections).
There is also quantity: 20 IronRidge XR-100 rails, silver, at 14 feet long. The hardware for the racking system, and microinverters, includes quantity: 40 IronRidge Universal Fastening Objects (UFO), with quantity: 40 IronRidge UFOs’ with Stopper Sleeves, and quantity: 40 IronRidge T-Bolt Bonding Hardware for Enphase microinverters. This is almost everything that is needed for a complete system - the buyer will need to supply rail attachments (roof/ground mounted systems), depending on their installation.
There are approximately 9 microinverters that are really underperforming, compared to other microinverters -
