PV Modules & Photovoltaics: Compliance Requirements for Solar Energy
Solar energy has become a central pillar of the global energy transition. However, as demand for photovoltaic systems rises, so do the legal requirements for market participants. Since October 24, 2015, PV modules have also fallen within the scope of the WEEE Directive.
Scope of Application: Which products are affected?
Depending on their size, photovoltaic modules can be classified as large appliances (Category 4) or small electrical appliances (Category 5): Solar modules with no side longer than 50 cm are considered “small appliances.”
Since photovoltaic modules of the same type can be used for both private and commercial purposes, they fall under the term “dual-use devices” and are classified as B2C devices.
This means that even those who only supply businesses require a B2C registration.
Who is responsible?
- Manufacturers & Importers (Distributors): Registration with the EAR Foundation
- Retailers & Online Stores: Organize the return of used equipment
- Individuals / System Operators: Old PV modules do not belong in household waste; they must be properly disposed of at a collection point.
The Core Obligations
Just as with conventional electrical appliances, batteries, or packaging, specific manufacturer obligations apply in the field of photovoltaics.
In Germany, the ElektroG4 serves as the relevant legal framework.
- Manufacturer registration: Anyone placing PV modules on the market in Germany must be registered with the ear Foundation.
- Reporting: The quantities of modules placed on the market must be reported regularly and accurately.
- Europe-wide compliance: Since each EU country implements the WEEE Directive individually, companies operating across borders must comply with the respective national requirements (EPR) for PV modules.
The Challenge: Waste Disposal and Recycling
The greatest challenge in the lifecycle of solar modules lies in the proper disposal of defective or end-of-life components.
Coordinating pickups in Germany is particularly critical: as soon as the ear Foundation issues an official pickup order, speed is of the essence. The collection from the recycling center must take place within 72 hours.

Specific requirements for manufacturers of PV panels

Registration
Photovoltaic manufacturers typically fall under the scope of all relevant legal areas, as they sell not only modules - which are subject to the ElektroG4 - but also battery storage systems and packaging. In accordance with these legal requirements, proof of registration must be provided.

Quantity reports
Similarly, PV manufacturers are required to report their input and output volumes to the authorities and relevant systems.

Insolvency-proof guarantee
Since PV modules and inverters are covered by the ElektroG4 and can be used in private households, an insolvency-proof warranty is required here, just as it is for any B2C device.

Return
Photovoltaic manufacturers may also be responsible for coordinating the collection of ear. They often use their own voluntary take-back programs as a means of meeting collection quotas.
FAQ
What exactly is a solar panel?
Photovoltaic modules, or PV modules for short, are the most important component of a photovoltaic system, as they convert sunlight into usable electricity.
How long does a solar panel last?
Most solar panel manufacturers offer warranties of 20 to 25 years. Accordingly, buyers can expect the system to last at least that long. The actual lifespan of the panels is 30 to 40 years. In some cases, it can even exceed that.
Where do I need to register my solar panels?
Traditional photovoltaic manufacturers that sell inverters and battery storage systems in addition to their panels quickly fall under these three legal categories. Accordingly, under the ElektroG4 and BattDG, registration with the ear Foundation is required, as well as enrollment in a battery take-back system. For packaging, registration with the central packaging register and licensing with an approved dual system are required as standard.
What is the difference between solar and PV?
Fundamentally, the difference between photovoltaics (PV) and solar thermal energy is that photovoltaics generates electricity, while solar thermal energy produces hot water. Both systems harness the sun’s energy.
