The hardest part of any rooftop solar job is the layout, and here it was handled with old-school care. Truss positions were found by tapping shingles with a framing claw hammer, then panel locations were marked out with a tape measure, a yellow lumber crayon, and a red chalk line. That kind of patience up front is what makes a racking job look tidy years later, in my opinion.
The build itself is a grid-tied residential system the maker put together personally, rated at 8.06 kW, with 24 all-black monocrystalline modules split into two arrays on the roof planes. The kit included Next Energy Alliance modules and a SnapNrack mounting solution. L-foot brackets lag-bolted into the rafters hold the parallel aluminum rails, and the APsystems microinverters sit bolted inside the rails, daisy-chained by a trunk cable through the racking channel. Flashings were sealed underneath around the bolt hole and slipped under the shingles, which seems like the right way to keep a roof watertight.
The electrical side is what stands out to me. An AC combiner box holds 20-amp breakers for each branch circuit, feeding a dedicated two-pole 40A quad breaker indoors, with an external knife-blade disconnect on the siding and bare copper grounding wire running along each rail row into lugs with piercing pins. The wiring is neat too: DC leads zip-tied through frame eyelets, off the shingles, and trunk cable joined to indoor Romex with wire nuts in a roof junction box. The whole thing passed municipal inspection and now runs on a bi-directional net meter.
The cost story is striking: $13,300 before incentives, dropping to $8,243 after the federal tax credit and a state credit, against contractor bids of $17,000 to $21,700. Payback lands around 6.2 years with incentives. One open question: the microinverter label is only shown as YC600 or QS1, so the exact model remains unclear.
