Pv panel is an open-source printed circuit board by ngrabbs, from the ngrabbs/ember repository on GitHub, published under the CC0-1.0 licence. It is a 2-layer board of 82.5 × 98 mm with 23 parts on 6 nets, routed with 35 tracks and 0 vias.
It is built around the S2B-PH-SM4-TB(LF)(SN), SB140 and SM141K10TF, with the STPS1L30MF among its other parts. Its parts include 1 diode and 1 connector.

schematic, routed PCB, project-local footprint libraries, and solar-module
STEP model. Diode and connector models are embedded in the board and footprints.
The recovered schematic follows the routed PCB's six nets and eleven named components. The original free pads and mounting holes remain board-only items. Footprints are linked to the recovered symbols; their placed geometry is retained in individual project-local library variants.
exports/pv_panel_rev_D_presentation.step includes colored components, solar-cell
detail, copper, pads, soldermask, and silkscreen.exports/pv_panel_rev_D_mechanical.step provides simpler board/component geometry.Both files use millimeters and a board-centered XY origin. They reopen as valid OpenCascade shapes; an actual Onshape import has not been tested.
Removed zero-length outline segments, repaired PV2 pad 1's net assignment, restored the original 10 mil zone clearance, refilled the ground zones, removed isolated copper and a tiny dangling track stub, and corrected through-hole paste settings and silkscreen collisions. Corner copper rings were reduced from 6.4 mm to 5 mm to satisfy the existing 0.5 mm edge-clearance rule; drill diameters, mounting centers, and the outline are unchanged.
The native schematic import had scale and connectivity defects, so the working schematic was reconstructed with standard KiCad symbols and checked against the PCB pin connectivity. The archived sources disagree on diode population: the older drawing omits D1 and labels CR1–CR5 as RBR1MM60ATR, while the PCB includes D1=SB140 and labels CR1–CR5 as STPS1L30MF. This project follows the PCB. Confirm the intended/fitted diode part numbers before fabrication.
The saved project passes KiCad DRC, ERC, and schematic parity with zero findings. All six nets match pin-for-pin across the eleven named components. Both STEP exports contain valid CAD shapes (58 solids for mechanical, 129 for presentation), and top/bottom renders were visually inspected. These checks cover the recovered design and mockup export; hardware qualification remains a separate activity.

It measures 82.5 × 98 mm and has 2 copper layers, 0.41 mm thick.
23 parts, built around the S2B-PH-SM4-TB(LF)(SN), SB140, SM141K10TF and STPS1L30MF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the ngrabbs/ember repository on GitHub, at the commit this page was made from: the board is hardware/pv_panel/kicad/pv_panel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
