Prefabricated Photovoltaic Sunroom Solution

Sep 10,2026

Solution Overview

This solution is based on the core logic of "one sunroom per household, self-generation for self-consumption, and surplus power fed to the grid." It deeply integrates the shading and leisure functions of a traditional sunroom with a photovoltaic power generation system, creating a high-quality home space that combines power generation income, residential comfort, and green low-carbon living. The solution adopts fully prefabricated polymer connection technology, with factory prefabrication and on-site modular assembly. No welding or open flames are required. A single-household sunroom takes only 1–2 days from stocking to delivery. The product combines multiple advantages such as aesthetics, practicality, energy conservation, environmental protection, and thermal insulation, and is widely applicable to villa courtyards, rural self-built houses, building rooftops, terrace gardens, and other scenarios. It is currently the fastest-to-implement and best-experience solution in the residential distributed photovoltaic field.

Core Advantages of the Solution

1.Fully Prefabricated Structure, Ultra-Fast Delivery Without Welding
The project entirely adopts polymer prefabricated connectors + standardized square-tube frames, subverting the traditional welding construction model. All components are prefabricated in the factory in advance, and on-site work only requires an electric wrench to complete bolt locking. No open-flame operations or professional welders are needed throughout the process. For a single standard sunroom, from material entry to overall completion, only 1–2 days are needed, improving efficiency by over 50% compared with traditional welding construction. It is also not restricted by rainy season construction, truly achieving rapid delivery all year round and in all weather conditions.

2.Green Power for Self-Consumption, Diversified and Stable Returns
High-efficiency photovoltaic modules are laid on the roof of the sunroom to build a residential distributed photovoltaic power generation system. The power generation mode adopts self-generation for self-consumption and surplus power fed to the grid. The electricity generated can fully cover the daily household electricity demand and the power needs of sunroom lighting, air conditioning, smart home devices, etc., greatly reducing household electricity expenses. Excess electricity is fed into the national grid, continuously generating grid-connected income. Taking a 30㎡ standard sunroom as an example, the installed capacity is about 5kW, and the average annual power generation can reach over 5,000 kWh, with stable and considerable long-term returns.

3.Superb Durability, 25-Year Maintenance-Free
The core structure adopts polymer connectors + hot-dip galvanized square tubes, paired with Grade 10.9 Dacromet bolts and self-locking anti-loosening nuts, with industry-leading hardware configuration. The product has passed rigorous third-party authoritative testing: 1,000-hour salt spray test with no white rust and no corrosion, capable of withstanding Level 15 super typhoons, and suitable for various complex environments such as coastal, chemical, high-temperature, and high-humidity areas. The polymer material itself is non-conductive, rust-free, and corrosion-resistant. The overall structure has the same service life as the photovoltaic modules, requiring no replacement of accessories and no special maintenance throughout its 25-year life cycle, greatly reducing later operation and maintenance costs.

4.Standardized Modular Design, Convenient and Worry-Free Acceptance
The entire sunroom is disassembled into standardized modular components, with unified specifications for dimensions, accessories, and connection styles. Parts are highly interchangeable, and the layout is neat and uniform. It has a complete set of product technical specifications and installation acceptance criteria. Module splicing nodes, mechanical parameters, and appearance styling are all well-documented, and acceptance items are clear at a glance. The modular forming effect is neat, and the appearance, structure, and load indicators are intuitive and easy to verify, reducing acceptance disputes and greatly shortening the overall acceptance process.

5.Fully Detachable and Relocatable Structure, Assets Can Be Reused
This project adopts a fully modular dry-assembly structure. The entire sunroom has no welding and no permanent fixation, and all connection nodes are standardized bolt-assembled structures. The overall structure possesses complete detachability, relocatability, and re-installability. A traditional welded sunroom cannot be relocated or disassembled after completion; it can only be scrapped entirely when the house is renovated or relocated. A prefabricated sunroom can be wholly disassembled and rebuilt elsewhere, transforming the sunroom from a "one-time project investment" into a movable, transferable, and reusable fixed asset, greatly enhancing asset residual value and reducing investment losses.

6.One Room, Multiple Uses — Both Quality Living and Green Investment
The prefabricated photovoltaic sunroom is not only a power generation facility but also an extension of high-quality living space — it is a leisure space for family gatherings and parent-child activities, a functional space for green plants and flower rooms, tea rooms, and studies, and also a "home power station" that continuously generates green power income. Shading, leisure, power generation, and energy storage are integrated into one, with a one-time investment and multiple value returns. It is currently the solution with the best user experience and the most balanced investment return in the residential photovoltaic field.
