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.

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.

• 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.

• 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.
