• Power Tolerance ~±3 % typical

• Cell Type Monocrystalline silicon (most common)

• Operating Temp Range ~-40 °C to +85 °C

• Max System Voltage ~1000 – 1500 V DC

• 🛠 Mechanical & Construction

• Number of Cells: Typically ~120 cells (6 × 20) or similar layout

• Weight: ~18 – 25 kg depending on build

• Dimensions: ~1680 × 1000 × 30–40 mm (varies by brand)

• Material: Tempered glass with an aluminum frame – weatherproof and durable

• Junction Box: Typically IP65-rated for outdoor use

• Connectors: Standard MC4 or compatible plugs

• 📌 What These Specs Mean

• Rated 350 W output means the panel can produce up to 350 W under ideal sunlight and temperature conditions (1 000 W/m² irradiance, 25 °C cell temperature). Actual output varies with weather, orientation, and shading.

• Vmp & Voc values (voltages) help you choose matching charge controllers or inverters — higher voltages suit higher-voltage battery banks or grid-tie systems.

• Efficiency indicates how effectively the panel converts sunlight into electricity — higher efficiency panels produce more power per unit area.

• 📌 Typical Uses

• Rooftop solar installations for homes and small businesses

• Hybrid or off-grid solar battery charging systems

• Powering solar inverters for appliances and electronics

• Vs, cabins, or mobile solar setups
