Photovoltaic installation
Description
Generate your own electricity and reduce your reliance on the grid with a self-consumption solar panel system. Designed for homeowners looking to lower electricity costs, increase energy independence, and use clean, renewable solar energy, this system lets you maximize on-site consumption. With optimized solar power storage and usage, you can make the most of your photovoltaic system while ensuring long-term savings and sustainability.
System & Components
How it works
The most common installation for this type of system is on a roof, whether it’s your home or an outbuilding like a garden-house. As a single-family homeowner, you can set up the system for your own use. If you co-own a property, you can collaborate with other owners to plan a collective self-consumption installation.
It’s also possible to share your solar-energy with neighbours, enabling a local energy community.
Joule provides the complete PV system:
