Who we are
We are a photovoltaic module manufacturer founded in 2008, with our operational headquarters in Hangzhou, China. We supply solar modules for a range of applications, including residential, commercial and utility-scale PV systems. In addition, we are active in the development and investment of commercial & industrial rooftop PV projects, as well as in investment and acquisition services for large-scale ground-mounted PV plants.
We have localized sales and after-sales teams in Europe, withmultiple in-stock warehouses in several countries, providinglocalized services from pre-sales and consultation to after-salessupport, ensuring a quick response to the needs of European PVusers.

As a PV module manufacturer and solution provider with long-standing experience in Germany and across Europe, Maysun Solar supports both commercial & industrial rooftop PV and PV project development.
In-house development of high-performance modules
High-performance modules developed in-house
With TOPCon, HJT and IBC technologies, our modules offer efficiencies of 21–24%+ and a 25-year linear performance warranty, with TÜV Rheinland certification (IEC 61215/61730).
Intelligent system integration
AI-based dynamic optimisation across modules, inverters and storage enables system PR values above 85% and increases energy yield by 10–15%.
Local EPC capability in Germany
Through strategic partnerships with established German EPC companies, we meet grid feed-in standards and can shorten project delivery timelines by up to 30% (depending on scope and site conditions).
Risk management
Smart O&M: real-time performance monitoring via an automated IoT platform and intelligent fault alerts reduce O&M effort and costs. Typical annual O&M costs are below 2% of electricity revenue.
Financial protection via leading insurers: cover for natural hazards and operational risks.
Compliance and certifications: CE, TÜV, VDE-AR-N 4105 assessment and alignment with applicable German building regulations.
Intelligent system integration
We work with local developers and EPC installers in Germany and combine this with an advanced supply chain to deliver high-efficiency PV solutions for industry, agriculture and ground-mounted projects, alongside optimisation and storage concepts.
- Strong financial backing: Supported by green financing policies and renewable energy funds, we can provide project finance support and equity partnership models to facilitate implementation.
- Technology-driven performance: In-house developed bifacial glass-glass modules (efficiency ≥22.5%) with low-glare design. System PR up to 88% (IEC 61724) and LCOE < €0.04/kWh (project-dependent).
- Local delivery: A dedicated renewables team responds quickly to customer requirements and supports efficient project negotiations and transactions.
Acquisition and management of RTB PV projects
We cooperate with investors to acquire Ready-to-Build (RTB) PV projects in Germany and other EU countries. Following acquisition, we support construction coordination, operation and subsequent asset transactions with partners.
Certified to TÜV, CE and RoHS requirements
Our modules are assessed against RoHS requirements, helping improve environmental compatibility for rooftop and industrial rooftop PV and reducing the risk of hazardous substances. Maysun Solar’s production facilities follow robust manufacturing processes and quality control systems to ensure each module is safe and consistent. Our products are certified by recognised organisations, including TÜV and CE, providing customers with additional confidence and reliability.
Local service across Europe
Our European team provides dedicated sales and after-sales support, backed by multiple warehouse locations across key logistics hubs. With regional stock availability and close collaboration with partners, we support installers, distributors and project developers with reliable delivery, technical coordination and responsive service — helping ensure smooth project execution across European markets.
Founded in 2008, Maysun Solar is a global manufacturer of high-performance photovoltaic modules, bringing together advanced cell technologies, rigorous quality control, and worldwide production and service capabilities.
Frequently Asked Questions
Answers to the most common questions about commercial and industrial photovoltaic systems
What is commercial and industrial photovoltaics?
Commercial and industrial photovoltaics refers to the installation of solar systems on non-residential buildings such as factories, warehouses, office buildings, and shopping centers. These systems generate electricity from sunlight for on-site consumption and can feed surplus energy into the public grid. Typically installed on company rooftops or unused areas, they offer benefits such as high self-consumption rates, predictable economic returns, and a tangible contribution to companies’ sustainable energy transition.
Which types of companies are suitable for commercial and industrial photovoltaics?
Commercial and industrial photovoltaics is particularly suitable for companies with high energy consumption and available surface areas, such as factories, warehouses, logistics centers, supermarkets, and large business complexes. Companies with large roof areas and stable electrical load profiles can benefit most from solar self-consumption.
What is the payback period for a commercial or industrial photovoltaic system?
The payback period for a commercial or industrial photovoltaic system generally ranges from 4 to 7 years, depending on factors such as local electricity prices, self-consumption rate, available incentives, and system size. In regions with high energy costs or active subsidy schemes, the payback period can be reduced to less than 4 years.
What quality guarantees do your solar panels offer?
Maysun Solar glass-glass solar panels come with a 30-year product warranty, while glass-foil panels offer a product warranty of 15 to 25 years. All of our solar panels are backed by a performance warranty of 25 to 30 years. Detailed information can be found in the product data sheets available on the respective product pages.
Have your solar panels been tested and certified by European authorities?
Maysun Solar holds multiple certifications from recognized institutions and standards, including TÜV, CE, IEC, ETN, MCS, ISO, and others. The relevant certification documents can be viewed and downloaded on our certifications page.
Which products are currently in stock? Where are your warehouses located?
Maysun Solar’s current inventory mainly includes IBC solar panels, HJT solar panels, balcony photovoltaic systems ranging from 600W to 800W, the Twisun Double-Glass Full-Black series, the Double-Glass Black Frame series, and Venusun Full-Black solar panels.
