Compact 40W Monocrystalline PV Panel IP67 Junction Box For 12 Volt Battery Charging

Compact 40W Monocrystalline PV Panel IP67 Junction Box For 12 Volt Battery Charging

Product Specification:

Our 40W monocrystalline PV solar panel comes with 28 high‑efficiency mono solar cells, delivering stable 40‑watt power output for off‑grid power needs. Sized 58039525mm and weighing only 2.55 kg, this compact‑sized solar module is lightweight for easy mounting, transport and outdoor installation. Built‑to‑withstand harsh outdoor weather, it is a budget‑friendly energy solution for residential yards, cabins, outdoor equipment and remote off‑grid systems.

Electrical Characteristics (STC):

  • Maximum Power (Pmax): 40W
  • Open Circuit Voltage (Voc): 19.12V
  • Short-Circuit Current (Isc): 2.55A
  • Voltage at Pmax (Vmp): 16.53V
  • Current at Pmax (Imp): 2.42A
  • Maximum System Voltage: 700V DC
  • Power Tolerance: 0 to +4.99W

Mechanical Specifications:

  • Dimensions: 580 x 395 x 25 mm
  • Weight: 2.5 kg
  • Solar Cells: Monocrystalline 182mm (28 cells, 2x14 configuration)
  • Frame: Anodized Aluminum Alloy
  • Front Glass: 3.2mm Tempered Glass
  • Junction Box: IP67 rated, with 50cm output wires (custom length available) and MC4-compatible connectors.
  • Mechanical Load Capacity: 5400Pa (Front) / 2400Pa (Rear)

Temperature & Operational Ratings:

  • Operating Temperature: -40°C to +85°C
  • Nominal Operating Cell Temperature (NOCT): 45±2°C
  • Pmax Temperature Coefficient: -0.35%/°C

Packaging:

  • 80pcs per pallet (Pallet Dims: 630x1100x930mm, ~235kg).

Why It Stands Out – Key Features

  1. Proven High-Efficiency Performance: Features 182mm monocrystalline cells with 17.46% module efficiency, confirmed by detailed I-V curve data showing stable output from 200W/m² to 1000W/m² irradiance.
  2. Engineered for Reliability & Easy Installation: The robust 3.2mm tempered glass and aluminum frame ensure durability. Pre-drilled grounding holes and drainage holes (as per technical drawing) facilitate secure, weather-resistant mounting and system longevity.
  3. Superior Low-Light & Temperature Performance: A favorable temperature coefficient (-0.35%/°C) and optimized NOCT ensure minimal power loss in heat. The I-V curves demonstrate effective energy harvest even in low-light conditions (e.g., 200-400W/m²).
  4. Ready for Seamless Integration: Comes with industry-standard MC4-compatible connectors and a 50cm cable, allowing for quick, tool-free connection to most charge controllers and systems.

Compact 40W Monocrystalline PV Panel IP67 Junction Box For 12 Volt Battery Charging

Ideal Application Scenarios

  • Mobile & Recreational Power: Perfect for maintaining batteries on RVs, camper vans, boats, and yachts.
  • Off-Grid Systems: An excellent component for powering small cabins, sheds, remote monitoring stations, and telecommunications equipment.
  • DIY Solar Projects: Ideal for building portable power stations, solar generators, or charging kits for tools and electronics.
  • Agricultural & Industrial Uses: Reliable power for electric fencing, water pumping systems, and off-grid lighting.
