The SunGold Power 450 Watt Monocrystalline Solar Panel (SG450WM) is a high efficiency monocrystalline PERC module built with 120 half-cells (6 x 20). Each panel is rated at 450 watts and is certified to UL61730, with a CEC listing.
SunGold designs these panels for on-grid, off-grid, and hybrid solar systems, from cabins and RVs to complete off-grid homes. An IP68 junction box and connectors, a corrosion-resistant aluminum frame, and load ratings of 5400Pa for snow and 2400Pa for wind help them hold up outdoors. Choose a 2 to 20 panel pack using the options on this page.
PERC (passivated emitter and rear cell) technology improves light capture, and half-cell construction reduces resistive losses and limits the impact of partial shading on the panel's output.
At standard test conditions, each panel produces 450 watts at 34.2V and 13.16A, with an open circuit voltage of 41.72V and short circuit current of 13.82A.
Load testing to 5400Pa for snow and 2400Pa for wind, plus an IP68 junction box and connectors rated for temporary immersion up to 1 meter, help the panels stand up to harsh weather.
A 1500V maximum system voltage gives flexibility for long series strings on high voltage MPPT inverters, and 12 AWG output cables (1 ft per cable) connect to standard solar extension cables.
SunGold estimates a 450 watt panel produces about 1.8 to 2.7kWh per day, depending on peak sun hours at your location.
Off-grid homes and cabins. Build an array sized to your battery bank and all-in-one inverter.
Grid-tied and hybrid systems. Reduce power bills by pairing the panels with a hybrid inverter and battery storage.
Ground and pole mounts. Install in open areas where panels can be angled for the best production.
Farms, shops, and outbuildings. Power pumps, lighting, and equipment far from the grid.
Versus N-type panels. N-type panels offer longer linear warranties and slightly lower degradation. PERC panels like this one are a proven, cost-effective choice.
Versus higher wattage panels. Larger panels mean fewer modules and connections, but they are heavier and harder to handle on a roof. Choose the size that fits your mounting space and installation crew.
Versus full pallets. For large arrays, SunGold also offers full pallets, which can be more efficient for big installations.
This may be a good fit if
Yes. SunGold confirms the panel is waterproof, with an IP68-rated junction box and connectors.
It depends on your inverter or charge controller's PV voltage range, your system voltage, and any shading. Check your inverter's MPPT range before arranging the array.
