Against the backdrop of the energy crisis and global green transition, 2022 became a breakout year for the balcony PV market, especially the balcony solar racking industry. No longer a niche concept, balcony photovoltaics quickly evolved into a key way for urban residents in Europe and the US to participate in the energy transition.

1. Market Boom: Energy Crisis and Policy Tailwinds

In 2022, balcony PV became a true "hit" in Germany. So-called "plug-in" solar modules mounted on balcony railings, external walls, or even freestanding garden structures could be seen everywhere. According to reports, by the end of 2022, nearly 200,000 such systems were already in operation in Germany. Market enthusiasm led to extended delivery times – orders for a micro-PV system sometimes took more than a year – yet consumers remained undeterred, willingly paying premium prices on e‑commerce platforms.

A key driver behind this wave was policy support. In 2022, Germany introduced a tax exemption for PV systems up to 30 kW, greatly stimulating demand for small residential PV. That same year, the French Senate approved legislation requiring solar installations on outdoor parking lots and mandating 50% PV coverage on rooftops, further fueling growth in the European market.

The upheaval in global energy markets also added fuel to the balcony PV boom. Ukrainian entrepreneur Karolina Attsypodina, who founded the company WeDoSolar in February 2022, seized this historic opportunity. Her design of vertical solar panels was intended to allow ordinary European users, without technical knowledge, to easily install PV equipment on their balconies and thereby reduce dependence on Russian natural gas.

2. Technology and Products: From Simple Racking to Smart Integration

Faced with the constraints of balcony spaces, balcony solar racking technology in 2022 showed a clear trend toward lightweight design, easy installation, and multi‑scenario adaptability.

Materials & Structure: Mainstream balcony racks were typically made of stainless steel and aluminum alloys – corrosion‑resistant, lightweight, and aesthetically pleasing. For example, Fujian Kesun New Energy exhibited balcony easy‑fit racks at the German International Solar Technology Expo (Intersolar) in late 2022. With minimal parts, these racks could be installed on railings or walls. Their universal simple rack even suited gardens, railings, and other scenarios, offering adjustable tilt angles and simple installation.

Plug-and-Play: Lightweight design was another major highlight. German startup WeDoSolar launched a balcony solar module weighing only 1.6 kg. It could be clipped onto balcony railings like a clamp and came with a micro‑inverter that could be plugged directly into a standard home power outlet, enabling self‑installation without an electrician.

Adjustability: To maximize power generation, adjustable racks were very popular. For instance, Sunforson launched a balcony PV rack in August 2022 that could be installed at different angles (e.g., 45°) depending on snow and wind loads, with an option for angle adjustment.

3. Policy and Installation Guidelines

In 2022, China’s National Energy Administration also issued the Household PV Construction Operation Guide (2022 Edition) to regulate the domestic residential PV market. The guide clarified pre‑installation consultation procedures, the list of required documents for grid‑connection applications, and stressed the importance of selecting qualified construction companies for installation. Although the guide primarily focused on rooftop PV, its regulatory approach laid a foundation for the future adoption of balcony PV in China.

4. Key Players and Competitive Landscape

In 2022, the balcony PV market saw many innovative startups competing alongside traditional giants.

Startups: WeDoSolar, as a rising star, quickly received thousands of orders thanks to its ultra‑light, easy‑to‑install product. Its innovative business models (direct purchase, free leasing tied to EV CO₂ certificates, employee benefit plans) also drew industry attention.

Chinese manufacturing power: Chinese PV racking companies had a strong international presence. Companies like Kesun New Energy and Grace Solar frequently appeared at international exhibitions in Germany, France, Australia, etc. Leveraging efficient manufacturing capabilities and localized services, they provided high‑quality balcony PV racking solutions to global markets.

Market valuation: From a macro perspective, the global solar PV racking market (including balcony racks) already showed great potential in 2022. According to statistics, the global PV racking market was valued at approximately US$24.1 billion in 2022, with Europe holding a dominant share due to its early adoption of renewable energy technologies.
