Cost and practicality. 300W panels cost 15-20% less per watt. They're easier to handle (15kg vs 25kg+), cheaper to ship (fits in SUVs), and replacement parts are everywhere. For most RVs, boats, and cabins, 300W is the sweet spot.
Our panels have a -0.34%/°C temperature coefficient – among the best. On a 45°C (113°F) day, a 300W panel still produces ~280W (7% loss) versus cheaper panels at -0.50%/°C producing ~255W (15% loss). That's 25W more per panel on every hot day.
