70W Monocrystalline Solar Panel | High-Efficiency Module for Off-Grid Solutions

Product Specification:

Unlock reliable, clean energy with the JST-EVMH-40W, a premium 40-watt monocrystalline solar panel. Engineered for exceptional efficiency and durability, this compact module delivers superior performance for a wide range of off-grid and mobile applications, making it the smart choice for sustainable power.

Electrical Characteristics (STC):

  • Maximum Power (Pmax): 70W
  • Open Circuit Voltage (Voc): 17.59V
  • 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: 985 × 395 × 30 mm
  • Weight: 4.24 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.
Why Choose Us?
  • Optimized for 12V Systems:​ The 17.59V output is perfectly matched for charging 12V batteries, minimizing reliance on inefficient charge controllers.
  • Designed for Mobility:​ Lightweight yet robust construction makes it an excellent choice for RV and boat applications where weight and vibration are concerns.
  • Built to Last:​ Rigorous quality control and high-quality materials result in a long service life and consistent energy production.
  • Easy Integration:​ Pre-drilled grounding and drainage holes simplify installation and protect your investment from water damage.
Application Scenarios
  • Recreational Vehicles (RVs) & Campers:​ Maintain house batteries while on the road or at the campsite.
  • Marine & Boating:​ Provide auxiliary power for trolling motors, onboard electronics, and battery maintenance on sailboats and fishing boats.
  • Off-Grid Cabins & Sheds:​ Serve as a primary or supplementary power source for remote buildings and weekend getaways.
  • Remote Monitoring Systems:​ Power security cameras, weather stations, and communication equipment in areas without grid access.
