Check electrical fit
Each panel has 41.72V open-circuit voltage and 13.82A short-circuit current. Account for series voltage, parallel current and cold-weather voltage rise when designing the array.
Plan handling and mounting
Each panel weighs 49.2 lb and measures about 75.2 × 44.7 × 1.4 inches. Confirm the support structure, mounting method and available space for the chosen pack size.
What is included and how to choose a pack
Select a 2-, 4-, 6-, 8-, 10-, 12-, 14-, 16-, 18- or 20-panel pack. The selected option contains that number of SunGoldPower SG450WM 450W panels. Design the complete electrical system separately, including compatible mounting, wiring, protection, controller or inverter, and storage if needed.
- Panel electrical ratings: 34.2V Vmp, 13.16A Imp, 41.72V Voc and 13.82A Isc.
- SunGoldPower lists a 12-year materials/workmanship warranty and a 25-year 80% output warranty.
- Compare the selected pack’s total nameplate wattage with your site and equipment limits.

Frequently Asked Questions
Clear answers to common questions about this product, setup, compatibility, and use.
How many 450 W panels arrive with the selected SG450WMx2 option?
The quantity changes with the selected product variant. Confirm the option and Package Includes section before checkout; 450 W is the rating per module, not necessarily the total wattage of every selectable package.
Can the SG450WMx2 connect to a power station based on wattage alone?
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 SG450WMx2 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 the SG450WMx2 frame be clamped anywhere along its edge?
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.
Why might the SG450WMx2 show normal voltage but disappointing watts?
Output is not constant at the 450 W 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.
