Serious Power for Serious Off-Grid
A 250W solar panel is the workhorse of off-grid solar. Unlike smaller panels that require extensive wiring to reach useful power, these panels deliver substantial wattage in a single unit – perfect for RV roofs, cabin systems, marine applications, and home backup.
Available in 9 power options from 205W to 250W, with 12V, 24V, and 48V compatibility, you can build exactly the system your energy needs demand – from a single panel for weekend camping to a full array for year-round off-grid living.
Up to 21.08% module efficiency means more power from less roof space. Whether you’re mounting on a van, boat, or cabin, you get maximum harvest from every square inch.
Our 210mm split cell monocrystalline technology achieves 21.08% peak efficiency – significantly higher than standard 250W panels (typically 15-18%). This means:
More power in the same footprint
Fewer panels needed for your energy goals
Better low-light performance on cloudy days
Unlike basic panels limited to 12V, our series works with any battery bank voltage:
Single panel → 12V battery charging (Vmp 24-42V, works with MPPT controller)
Two panels in series → 24V system
Four panels in series → 48V system

Charge Controller
Controller Type Sizing for 250W Panel Efficiency Best For
PWM 20-30A 75-80% Budget builds, 12V only
MPPT 30-40A 95-98% Maximum harvest, 12V-48V
Recommendation: MPPT controllers provide 20-30% more power from the same panel – pays for itself within 1-2 years.
Battery Bank Sizing
Battery Type Capacity for 250W Panel Usable Cost

Yes. We specialize in custom size solar panels for volume orders. Contact us with your required: Wattage (any between 50W-400W) Dimensions Voltage Cable length and connector type Logo printing on frame or backsheet
Yes – that's exactly what they're designed for. Two 250W panels in series (Vmp ~80V) perfectly charges a 24V battery bank. Four in series charges 48V. Use an MPPT controller rated for the higher input voltage (150V or 250V models).
10-year materials and workmanship warranty – covers manufacturing defects, frame corrosion, junction box issues. 25-year linear power output warranty – guarantees ≥80% of rated power at year 25. Annual degradation ≤0.8%.
