The rise of plug-and-play photovoltaic systems has revolutionized the solar energy sector. These integrated kits facilitate installation without the need for major construction work, allowing more people to access this form of renewable energy. But a common question arises: how many panels can you actually connect to one outlet? Let’s analyze the options available to you. Configurations and Troubleshooting To maximize energy production while complying with safety standards, it is essential to understand the limitations imposed by electrical installations. Connecting multiple panels depends on various technical parameters, including the desired total power, the characteristics of your electrical circuit, and ADEME recommendations.
On a circuit protected by a 16A circuit breaker using a 1.5mm² cable, it is generally recommended not to exceed a solar injection of 350W, or approximately 1.5A. This helps prevent the risk of overheating during prolonged use. For higher-power installations, specific solutions are available.
Optimize your connections Optimize your connectionsFor those opting for a more powerful installation, a dedicated circuit allows you to connect up to 800W per outlet, or approximately 3.5A. On the other hand, a shared circuit must remain at a maximum of 350W. In this context, the choice of microinverters is crucial, as they play a crucial role in converting direct current to alternating current.
Some manufacturers, such as Sunology, allow up to four panels on a single outlet, but be careful! This option requires a thorough inspection of the existing installation before proceeding. Practical installation scenariosVarious configurations allow you to efficiently arrange your solar panels. For example, for a standard house with a recent electrical system, it is possible to:
Install two 400W panels on a dedicated circuit, totaling 800W.
Use a 600W panel on an existing outlet, taking care to limit consumption. In cases where a battery system is considered, the technical constraints change. Stored energy offers greater flexibility, but requires a specific spatial study to maximize its use. Analysis and Recommendations Analysis and Recommendations Before undertaking any installation work, it is advisable to conduct an electrical audit, especially in older buildings. This helps identify potential overload risks and optimize the efficiency of your system. The precautions taken will lead to a safe and efficient installation.
