Product details
| Specification | Likely Value / Range |
|---|---|
| Rated Power (Pmax) | ~ 120 W at STC |
| Voltage at Maximum Power (Vmp) | Probably ≈ 17-20 V (so that when under load into a 12 V battery via a charge controller it’ll work properly) |
| Current at Maximum Power (Imp) | ≈ 6–7 A |
| Open Circuit Voltage (Voc) | Maybe ≈ 22-25 V |
| Short Circuit Current (Isc) | Slightly higher than Imp, maybe 6.5-7.5 A |
| Efficiency | Monocrystalline panels typically offer higher efficiency than polycrystalline — maybe in the ~ 17-22% range depending on cell quality and design |
| Physical Size / Weight | Might be in the range of ~ 100-1,300 mm by ~500-700 mm or so; weight probably 7-10 kg — depends on frame, glass, build quality |
| Frame & Glass | Tempered glass front, anti-reflective coating if high quality; strong aluminum frame to handle weather, mounting |
| Connectors / Wiring | MC4 type connectors often, pre-drilled holes for mounting, junction box (often IP65 for weather resistance) |
| Warranty | Many Phoenix Germany panels are marketed with a long power output warranty (~ 25 years) and a product/material warranty (often shorter) |
| Operating Temperature & Durability | Should withstand typical sunlight, heat, rainfall, possibly some shade; built to resist weather, possibly corrosion, etc. |
What It’s Good For / Applications
Because of its size and power, this kind of panel is suitable for:
Charging 12V deep cycle batteries (for off-grid / backup / camping / RV use)
Lighting systems, small DC appliances, phone charging, small pumps, etc.
Integration into solar kits (house‐battery, solar charge controller)
Remote or mobile applications (boats, caravans, cabins)
As part of a larger array when more power is required
Things to Check / Be Aware Of
When buying or installing, you should verify:
Spec sheet: Especially the Vmp, Imp, Voc, Isc. Sometimes rated power is optimistic.
Charge controller compatibility: Since Vmp and Voc might be higher than 12V, make sure controller is rated properly. MPPT is better to extract more power.
Mounting angle and orientation: To ensure max sun exposure.
Shade: Even partly shading a monocrystalline panel can reduce output significantly.
Wiring losses: Cable thickness, connector quality matters.
Temperature effects: Panels’ power drops as they heat up; good ventilation helps.
Warranty & after-sales service: Especially for overseas brands or imports
