Scalable array design
Easy to build into larger systems when you need more charging capacity for bigger storage and daily energy use.
Built for energy projects
A strong fit for homes, cabins, workshops, mobile builds, farms, and commercial solar applications.
More solar input for stronger charging
Solar panels are what decide how quickly your system can recover energy during the day. This panel is a strong option for customers building or expanding an array for battery storage, backup power, and off-grid energy use.
- Adds solar input for battery banks, solar generators, hybrid inverters, and off-grid systems.
- Works well for expanding an existing array or planning a new solar charging setup.
- Built for customers who need dependable charging capacity for real energy storage needs.

Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
How many 370W panels arrive with the selected SG370WMx2 option?
The quantity changes with the selected product variant. Confirm the option and Package Includes section before checkout; 370W is the rating per module, not necessarily the total wattage of every selectable package.
Why does cold-weather voltage matter when stringing the SG370WMx2?
Use the exact module open-circuit voltage, operating voltage, short-circuit current, operating current, connector, polarity, and maximum series-fuse value. Apply cold-temperature voltage correction to series strings and add current correctly for parallel branches.
What should I expect from the SG370WMx2 outside laboratory test conditions?
The nameplate is measured under standard test conditions. Actual production changes with irradiance, sun angle, cell temperature, shade, soiling, cable loss, controller efficiency, and the battery or grid system's ability to accept power.
Can adhesive alone be assumed sufficient for mounting the SG370WMx2?
Use the published module dimensions, weight, approved clamp zones, mounting-hole layout, load rating, and required airflow. Verify roof structure, wind and snow design, setbacks, grounding or bonding, cable support, drainage, and safe service access.
How should mixed roof orientations be handled with the SG370WMx2?
Output is not constant at the 370W nameplate level. Check shade across cell strings, irradiance, angle, module temperature, dirt, connector seating, polarity, cable voltage drop, tracker assignment, and whether the battery or inverter is curtailing production.
