Commercial Solar PV Panels

Commercial PV Panel Kits and Rigid Solar Panels: Building an Array That Fits

PV panel kits in this collection are rigid, framed modules sold singly or in multiples for roofs, ground mounts, carports and trailers. The decision comes down to watts per panel, string voltage, and whether your mounting spot rewards bifacial cells. Commercial solar PV panels here suit a shop, a barn, a farm well or an off-grid business, and the smaller Rich Solar modules fit fleet vehicles and boats.

This collection holds 23 products from Sungold Power, Rich Solar and Anker. Prices start at $69 for a 50W Rich Solar panel and reach $1,000 for a pair of Anker SOLIX 440W panels; the Sungold Power kits run from $165 for two 100W panels to $980 for the 560W bifacial set.

How to choose commercial PV panels

• Watts per panel. Large-format modules mean fewer rails, clamps and connections. The Sungold Power 415W 48V Mono PERC Kit is the standard for a 48V off-grid inverter; the Sungold Power 560W Bifacial N-Type Kit adds up to 30% from reflected light on a ground mount, carport or white roof, with a 30-year warranty.
• String voltage. A panel's nominal voltage should match the charge controller or inverter input. The 415W and 560W kits are 48V-class; the Sungold Power 370W 24V Mono PERC Kit suits 24V banks; the SunGoldPower 200W 48V kit lists 37V Vmp per panel, which two in series push past 70V, so check your controller's maximum.
• Cell technology. The 370W PERC panel is rated at 20.3% module efficiency. N-Type TOPCon cells in the Rich Solar MEGA 200W 24V reach 24.8%, and the MEGA 150 reaches 25.3% cell efficiency, which matters when roof area is the limit.
• Footprint. The Rich Solar MEGA 100 SLIM is 50.0 x 15.7 in for narrow strips between roof vents on trailers and boats. The 2 x Anker SOLIX 440W set gives 880W from two modules for a compact home or shop array at 25% efficiency.
• Kit or bare panel. The Rich Solar 400W Charging Kit with MPPT Controller bundles two MEGA 200 panels with a 30A MPPT controller for a 12V or 24V battery.

Setup and usage tips

• Size the array with the Solar Kit Calculator. It takes your loads and ZIP code and returns the panel watts needed alongside battery and inverter size, so the array is not the weak link.
• Check the controller's maximum input voltage before wiring in series. Cold mornings raise panel voltage above the rated figure, so leave a margin.
• Mount bifacial panels at least a foot above a light-colored surface. Flat on a dark roof, the rear side collects almost nothing.
• Keep same-wattage panels in the same string. Mixing a 370W and a 415W in series drags the string down to the smaller panel's current.

Frequently asked questions

Which pv panels for sale here work with an existing 48V inverter? The Sungold Power 415W and 560W kits and the 200W 48V kit are the direct fits. Confirm the inverter's MPPT voltage window before setting string length.

Are bifacial panels worth it on a shop roof? Only if the roof is light in color and the panels are raised. On a carport or ground mount over gravel or concrete, the 560W bifacial set is the better value per watt delivered.

How many solar pv panels for sale in this range does a small business need? A workshop using 15 to 20kWh a day in a sunny state needs 4 to 5kW of panels, which is ten to twelve 415W modules.

Every panel and kit ships free to the mainland US from brand partner warehouses, usually within a few business days, with 30-day returns. For pallet quantities or help matching commercial pv panels to an inverter, call us and we will work through the string design with you.
