Solar Panel

The SunWell solar panel range brings high-efficiency N-Type TOPCon bifacial modules to homes, businesses, and solar farms that want more energy from the same roof or ground area. Built with double-glass construction and a 132-half-cell layout, the panels capture sunlight on both faces to raise real-world yield, while the TOPCon cell chemistry resists the steady power loss that older cell types suffer over time. The range spans four power classes so installers can match string voltage and layout to almost any project, and every module is engineered for harsh sites—high wind, snow load, and coastal or agricultural corrosion. They pair directly with SunWell hybrid inverters and storage systems to complete a single-brand solar-plus-storage solution.

Selection Guide

SunWell N-Type TOPCon bifacial panels suit rooftop, carport, and ground-mount projects where space is limited and every watt counts. The range offers four power classes—610 W, 620 W, 630 W, and 640 W—so you can match module count and string voltage to your inverter's MPPT window. Each panel delivers up to 23.7% module efficiency and uses a bifacial double-glass design: the rear face captures reflected light, adding roughly 5% to 20% yield depending on the albedo of the surface below, such as gravel, a white roof, or snow. For most fixed-tilt roofs, budget 10%–15% rear gain when estimating annual output.

Plan the string carefully. A single panel runs about 48–49 V open-circuit and 40–41 V at maximum power, with current near 16 A, so size your series strings against the inverter's maximum PV voltage and the 1500 V (IEC) system limit. The low temperature coefficient of power (−0.29%/°C) means the panels hold output better in hot climates than older PERC modules. Physically, each module is 2582×1134×35 mm and weighs 32.4 kg; 37 fit on one pallet, so crane or forklift handling is recommended for large arrays.

Durability matters for long-life installs. The frame and double glass meet 5400 Pa front and 2400 Pa rear static load, survive 25 mm hail at 23 m/s, and the junction box is IP68. Certifications include IEC 61215 / IEC 61730 and protection against salt mist, ammonia, and dust, making them suitable for coastal and farm sites. Choose the power class by your available area and target array size; higher-watt panels reduce balance-of-system cost per kW.

Frequently Asked Questions

What does "bifacial" mean and how much extra power do I get?

A bifacial panel generates from both faces. The rear side captures light reflected off the roof or ground, adding about 5%–20% annual energy depending on surface albedo—typically 10%–15% over a light-colored or reflective roof, and more over snow or white gravel.

How many panels can I put in one string?

Each panel is about 48–49 V open-circuit. Divide your inverter's maximum PV open-circuit voltage by this value and stay under the 1500 V (IEC) system limit, leaving margin for cold-weather voltage rise. Your SunWell hybrid inverter's MPPT range will tell you the safe string length.

Are these panels durable enough for harsh sites?

Yes. They use double-glass construction with 5400 Pa front and 2400 Pa rear load ratings, survive 25 mm hail at 23 m/s, and carry an IP68 junction box. They are certified against salt mist, ammonia, and dust, so they suit coastal, farm, and desert installations.

Why choose N-Type TOPCon over standard panels?

N-Type TOPCon cells resist light-induced and potential-induced degradation better than older types, so they keep more of their rated power year after year. With a low power temperature coefficient of −0.29%/°C, they also perform better in high heat, which matters for tropical and desert markets.

What warranty covers these panels?

SunWell panels carry a 12-year product warranty and a 30-year linear power warranty, guaranteeing at least 87.4% of rated output at 30 years with annual degradation of 0.4% or less. This long coverage reflects the panel's expected 25–30 year service life in the field.
