SHENZHEN, China – November 11, 2026 — Gaotu Innovation (Shenzhen) New Energy Group Co., Ltd., the manufacturer behind renewable energy brand GTPOW, has announced the official launch of its new 820W rigid balcony solar kit, a plug-and-play photovoltaic solution designed for renters, apartment homeowners and RV enthusiasts across global markets, especially Europe.

The complete GTPOW 820W balcony solar package consists of four pieces of 205W monocrystalline solar panels paired with the GT-MI-800D microinverter. Featuring up to 25% high conversion efficiency, the rigid panels adopt tempered glass construction with an IP67 dust and waterproof rating, capable of standing wind, rain and hail for long-term outdoor service.

A standout advantage of this balcony solar system is its ultra-low degradation performance: power degradation is controlled within 1% in the first year and only ≤0.4% per year afterward, ensuring stable power output over its service life. The built-in independent MPPT microinverter supports Wi‑Fi, Bluetooth and PLC communication, letting end users check real-time power generation data on mobile phones anytime.

Unlike traditional rooftop solar installations that require renovation and drilling, this GTPOW 820W kit supports simple railing mounting with zip ties. No permanent modification to the building structure is needed, making it perfectly renter-friendly. Beyond balcony use, the solar set can also be arranged on the ground or mounted on camper vans for off-grid power supply.

The whole system has passed IEC, CE, CQC and related international certifications, compliant with mainstream grid-connected standards in many countries. Gaotu Innovation provides 5-year workmanship warranty and 2-year power output warranty for the kit, bringing reliable after-sales protection for distributors and end consumers.

“More urban residents cannot install rooftop solar because they live in apartments or rented houses,” said the GTPOW product manager. “We created this 820W balcony solar kit to break that barrier. Clean solar power is no longer exclusive to homeowners with private roofs. It brings an affordable, easy way for ordinary families to save electricity costs and embrace low-carbon lifestyles.”

This new 820W solar kit is now available for wholesale distribution and retail sales globally. Distributors, solar retailers and cross-border sellers are welcome to contact the team for specification sheets, pricing and support.
