FAQs About Sungold Solar Panels
Our product portfolio covers a full range of solar photovoltaic solutions, including high‑efficiency glass solar panels, flexible solar panels, foldable portable solar panels, solar energy storage systems, solar outdoor lighting, solar backpacks, and wearable solar devices. We provide complete system products and customized solutions for residential, commercial, outdoor, and industrial scenarios.
“Our standard power ratings range from 5W to 500W. For higher capacity needs, we also offer high‑efficiency monocrystalline panels in the 400W to 550W range. Full OEM/ODM customization is supported, covering module specifications, mounting structures, brand logos, software white‑labeling, and packaging solutions, with flexible MOQ.”
Modules adopt monocrystalline PERC/TOPCon/dual‑glass technology with a conversion efficiency of 22.5%+ and a 25‑year linear power warranty (≤0.5% degradation in the first year). The supporting inverter has 99% MPPT efficiency, an IP65 protection rating, a 5‑year warranty (extendable to 10 years), and supports remote monitoring and OTA updates. Mounting brackets are made of aluminum alloy/stainless steel with a 10‑year warranty and resistance to Category 12 typhoons.
“Yes, the system is fully compatible with 1.2kWh to 5kWh LiFePO4 batteries. It supports both grid‑tied and off‑grid operation, and provides emergency backup power during outages. With energy storage, the self‑consumption rate reaches 80%–90%, which shortens the investment payback period by 0.5 to 1 year. A dedicated smart app enables real‑time monitoring of power generation, consumption, and energy storage data.”
Suitable for distributed scenarios including residential buildings, apartments, terraces, courtyards, and villas. Drill‑free dedicated brackets are provided, which do not damage building structures, have passed wind‑tunnel testing for Category 12 wind resistance, and are equipped with anti‑fall safety ropes, fully meeting the installation requirements of high‑rise apartments.
