420 watts solar panel
Features
Here are typical spec values for 420 W class panels, and what to look for:
| Parameter | Typical Value for 420 W Panel |
|---|---|
| Rated Power (Pmax) | ≈ 420 W (at STC) |
| Module Efficiency | Around 20-22% for many 420 W panels (higher efficiency = more power for given area) |
| Open Circuit Voltage (Voc) | e.g., ~37-44 V |
| Maximum Power Voltage (Vmp) | e.g., ~30-33 V in many older design; newer half-cell or large-format may be higher. |
| Short Circuit Current (Isc) | ~12-14 A typical in 420 W modules. |
| Dimensions & Weight | Often in the ballpark of ~1700 mm × 1100 mm × ~30-40 mm, weight maybe 20-25 kg |
| Cell Technology / Type | Monocrystalline (often “half-cell”, N-type, or TOPCon) in many modern panels for better performance and less degradation. |
| Frame & Build | Anodised aluminium frame, tempered glass front, weatherproof and designed for outdoor use (wind/snow loads in some regions) |
| Temperature Coefficient | Something like -0.3%/°C for power (i.e., power reduces as temperature rises) in many modules. |
| Warranty / Degradation | Good quality panels might come with 25-year performance warranties, and first-year degradation low (e.g., 1%) for premium models. |
420 watts solar panel
A 420 W solar panel is a photovoltaic module rated to produce about 420 watts of output under Standard Test Conditions (STC) — that is, when the sun’s irradiance is 1000 W/m², cells are at 25 °C, and other ideal conditions apply. For example, one specification sheet shows a panel rated 420 W with Voc ~ 38.26 V, Imp ~ 13.26 A.
In practical terms, it means the panel can contribute about 0.42 kW of peak power at its best. Over the course of a sunny day (say 5-6 good sun hours), you might expect something like 2-3 kWh of energy output (depending on location, tilt, shading etc). For example, one listing in Kenya for a 420 W panel says “…generate over 2kWh/day in ideal sunlight.” macire.co.

Features
Monocrystalline (higher efficiency) helps when roof/space is limited.
Good build for local weather: high sunlight, dust, maybe occasional storms.
Compatibility with 12/24/48 V systems, or grid-tie systems depending on your setup.
Ensure the module’s connector type (e.g., MC4) matches installer expectations.
