HENZHEN, China – Nov 10, 2026 – Gaotu Innovation (Shenzhen) New Energy Group Co., Ltd, operating under the GTPOW brand, announces the official release of its new 820W rigid balcony solar kit (Model GT‑FX205‑BD‑V1), a versatile plug‑in solar solution built for apartment balconies, yard fences, ground setups and RV power systems.

Designed to solve the long‑standing barrier that rooftop solar is unavailable for renters and high‑rise residents, this complete solar package includes four pieces of 205W monocrystalline rigid solar panels and one GT‑MI‑800D microinverter. The monocrystalline cells reach up to 25% conversion efficiency, capturing scattered sunlight efficiently in urban environments with limited space.

The integrated GT‑MI‑800D microinverter supports dual independent MPPT channels. This design minimizes power loss caused by partial shading — a common pain point for balcony installations blocked by buildings, clouds or hanging laundry. The microinverter delivers peak efficiency ≥96.5%, with Wi‑Fi, Bluetooth and PLC power‑line communication for real‑time power monitoring via mobile devices. Both panels and microinverter are rated IP67 for dust and water resistance, supporting stable operation from -25°C to +65°C.

“Most urban residents want to cut electricity bills and embrace clean energy, but they cannot install traditional rooftop solar,” said Product Director of Gaotu Innovation. “Our new 820W rigid kit balances durability, space efficiency and multi‑scenario flexibility. Unlike fragile flexible solar panels, our tempered‑glass rigid modules feature low degradation, with first‑year power decay ≤1% and annual degradation capped at 0.4% after the first year. The modules retain 88% of original power after five years, outperforming the general industry benchmark of 85%.”

The kit uses standard MC4 connectors for simple DIY assembly. Users can mount the panels on balcony railings with zip ties, set them on the ground, attach them to yard fences, or retrofit them on RV roofs with adjustable stainless steel brackets. The lightweight PVC frame reduces the overall load for balcony hanging applications.

The product portfolio holds ISO9001, ISO14001, ISO45001 management certifications, alongside IEC 61215, IEC 61730 and CE product certifications to meet mainstream global market requirements. It comes with a 5‑year workmanship warranty and a 2‑year power performance warranty.

This new balcony solar kit is now available for global B2B distribution and retail orders. Gaotu Innovation welcomes distributors, online retailers and solar installers worldwide to explore cooperation.
