YT Ø80mm Round Solar Panel
Overview
A small round epoxy-encapsulated solar cell, 80mm diameter, mounted on a black backing with two solder-tab terminals, wired out to a 2-pin JST-style connector (red/black leads visible in the supplied photo). This is a generic, widely-resold form factor — visually and dimensionally near-identical 80mm round panels are sold under many storefront names, typically rated somewhere in the 5–6V / 80–250mA range depending on cell count and seller, but no voltage or current rating is printed on this specific panel, so nothing electrical can be stated with confidence here.
Key specs
- Diameter: 80mm (per the
Ø80marking) - Voltage/current output: not printed on the panel, not confirmed — comparable 80mm round panels sold by other vendors range roughly 5V/80mA to 6V/350mA depending on cell technology and series/parallel wiring; do not assume a figure from this range without measuring
- Connector: 2-pin JST-style, red(+)/black(−) leads
Pinout
| Wire | Function |
|---|---|
| Red | + (positive) |
| Black | − (negative/GND) |
Connector pitch not confirmed from the photo. As with the NXD 103450 battery documented alongside this panel, Heltec boards (e.g. the WiFi LoRa 32 V4) use a 1.25mm-pitch JST-SH solar input — many generic solar panels in this class instead ship with 2.0mm-pitch JST-PH. Physically verify pitch before assuming a direct plug-in fit; do not force a mismatched connector.
Wiring / typical usage
Before wiring this to any board’s dedicated solar input (like the Heltec V4’s SOL connector), measure this panel’s actual open-circuit voltage in full sun with a multimeter. Feeding a charge controller a voltage well outside its expected input range can undercharge or, in the worse direction, stress the regulator — and since nothing is printed on this panel, “it looks like the other 80mm panels online” isn’t a substitute for measuring the actual unit in hand. Once voltage/current are measured and pitch is confirmed, wiring is a straight 2-wire connection: + and − to the host’s solar input.

Verification
Inferred from physical marking only (Ø80mm) — no manufacturer, datasheet, or printed electrical rating exists for this specific part. This is the lowest-confidence entry in the library so far: even the diameter is a physical-marking read rather than a measurement, and voltage/current are entirely unconfirmed. Do not wire this to a charge controller or board solar input without first measuring open-circuit voltage and short-circuit current directly.
Notes / gotchas
- No electrical rating printed anywhere on the panel — this is unusual even for generic parts (most at least print a voltage). Treat every number in this document except the 80mm diameter as unverified until measured.
- Connector pitch unconfirmed — same SH-vs-PH caution as the paired battery entry.
- If this panel is meant to pair with a specific board (e.g. Heltec V4’s onboard solar charge circuit), that circuit’s expected input voltage range should be checked against a real multimeter reading of this panel before relying on it — see the Heltec V4 component README’s power section for that board’s actual solar/battery charge behavior.
