FAQ
Q1：Is the panel bendable? What is the maximum bending radius?
A：This is an ultra‑thin flexible module designed for curved surfaces such as curved roofs, irregular structures, boats, and carports. At only 2mm thick, it offers excellent conformability. Follow the installation manual for safe bending; avoid excessive bending to prevent cell damage.
Q2：Do I need racks, foundations, or roof drilling? Will it damage roof waterproofing?
A：No brackets, concrete foundations, or roof penetration are required. It supports adhesive bonding, pressure strips, and clamps – fully preserving roof integrity and eliminating leakage risks. It reduces BOS cost by about 30% for faster, safer installation.
Q3：Can it generate power efficiently in low light, cloudy days, dawn/dusk, or high latitudes?
A：Yes. CIGS performs exceptionally well in diffused and low irradiance. At 600W/㎡, relative efficiency reaches 101.5% — 1.5% higher than conventional modules. It maintains stable output in dawn, dusk, haze, cloudy, and high‑latitude conditions to boost annual yield.
Q4：What are the structural requirements for weight and load?
A：Weight: 2.4kg (without adhesive) / 3.1kg (with adhesive). Areal density as low as 3kg/㎡ — just 1/10 of traditional panels. No structural reinforcement is needed for light steel roofs, metal roofs, color steel tiles, old buildings, and light‑duty factories.
Q5：Can it operate long‑term in high/low temp, coastal salt spray, high humidity, or dusty areas?
A：Yes. Operating temperature: ‒40℃ to +85℃. ETFE encapsulation (Water Cube grade) provides salt‑spray resistance, corrosion protection, moisture/dust resistance, and hail impact resistance. Built‑in bypass diodes eliminate hot spots. Fire rating B1, Safety Class II, ideal for coastal, industrial, urban, and harsh environments.
Q6：Does the panel have hot‑spot effect? How is safety ensured?
A：No hot‑spot effect. Bypass diodes are integrated into each cell and junction box to prevent hot spotting under partial shading. This greatly improves safety, reliability, and service life.
Q7：What is the protection rating of the junction box, connectors, and cables?
A：TE miniature junction box with MC4 compatible connectors, IP67 rated. Cable: 4.0mm² double‑insulated PV cable, 1000VDC, UV‑resistant, aging‑resistant, and wide‑temperature suitable for long‑term outdoor use.
