300W-400W Solar Panels: Budget and Retrofit Class

300W-400W Solar Panels: Budget and Retrofit Class

The 300-400W class is where retrofit, small commercial and budget residential arrays live: smaller modules, easier handling, and often the best cost per watt for tight roof layouts. This page lists the 300-400W modules we stock.

What to check before ordering

  • Module dimensions against legacy rail spacing on retrofits
  • Voc/Isc against the existing inverter's window
  • Certification and warranty for permit and lender packages
  • Pallet quantity and freight for small orders
