40W 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.

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.
