370W Solar Panels

370W Solar Panel Kits: Rigid 24V Modules for Cabins, Roofs and Ground Mounts

A 370w solar panel is a fixed, framed module for a system that stays where you put it: a cabin roof, a ground rack behind a workshop, a barn, or the roof of a fifth-wheel that lives on a seasonal site. At this wattage, four modules make roughly 1.5kW of array and eight make about 3kW, which covers a small home's daily essentials in most of the mainland US. The 24V output series-wires cleanly into strings for an MPPT charge controller or a hybrid inverter.

This collection holds one listing, the Sungold Power 370W 24V Mono Black PERC Solar Panels Kit, priced from $845 for the smallest kit up to $3,890 for the largest. Each module is rated at 370W with 20.3% efficiency, an IP68 junction box and a 25-year linear performance warranty, and it is described for on-grid, off-grid and hybrid systems.

How to choose a 370W panel kit

• Kit size. The Sungold Power 370W 24V Mono Black PERC Solar Panels Kit is sold in several quantities. Work backward from daily watt-hours: a cabin using 3,000Wh a day needs somewhere around 1,100W to 1,500W of panels depending on location, which is three or four modules; a full-time home with a well pump and a freezer needs the larger kits.
• System type. The kit is listed for grid-tie, off-grid and hybrid use. For off-grid, pair it with a battery bank and an MPPT controller; for grid-tie or hybrid, feed a string inverter or hybrid inverter and confirm the inverter's input window fits your string count.
• String voltage. These are 24V-class modules, so several in series quickly reach controller limits. Decide string length from the controller's maximum input voltage, allowing for the voltage rise on cold mornings.
• Environment. The IP68 junction box suits marine, coastal and high-humidity installs where cheaper connectors corrode. Mono black framing also blends into a dark shingle roof for a residential install.
• Efficiency versus space. At 20.3%, the PERC module gives 370W in a standard rigid footprint. If roof space is very tight, a higher-efficiency panel wins; if you have ground space, this kit's price per watt is the stronger argument.

Sizing tips

• Use the Solar Kit Calculator with your appliance list and ZIP code. It estimates panel watts, battery and inverter size together, so you can pick the kit quantity from the result rather than guessing.
• Check the 370w solar panel specifications on the product page for the exact frame dimensions and weight, then measure your roof rectangles or rack length before ordering.
• Order racking, MC4 cable, breakers and a disconnect in the same purchase. The kit is panels only.
• Angle for your latitude. A fixed tilt close to your latitude gives the best year-round output; add ten degrees for a winter-heavy cabin.
• Leave room to add a string later. Buying a controller with spare input capacity now is cheaper than replacing it when the freezer arrives.

Frequently asked questions

What is the 370w solar panel price per module? The kit starts at $845; divide the kit price by the number of modules on the product page to compare per-panel cost across quantities. Larger kits bring the per-panel price down.

Can I mix these with 400W or 450W panels? Not in the same series string. Different panels run at different currents, and the string drops to the weakest. Put different panel models on separate controller inputs instead.

Is a 370w panel enough for an RV? One panel supports lights, a water pump and device charging. A 12V compressor fridge and a full-time setup usually call for two or three, which is where the multi-panel kit sizes come in.

The kit ships free to the mainland US from our brand partner warehouses, usually within a few business days, with 30-day returns. Call us if you want help choosing the kit size for your roof or controller.
