• Energy self-consumption & lower bills — the kit allows you to generate your own electricity via the 20 panels + hybrid inverter + lithium battery, reducing the amount of electricity purchased from the grid.
• Smart storage & flexible use — surplus energy generated can be stored in the lithium battery for use when needed (at night, on cloudy days, etc.).
• Partial independence / reduced reliance on the grid — the system offers energy self-sufficiency, which can be beneficial in the event of a power cut or to reduce reliance on the public grid.
• Eco-friendly / clean energy — helps reduce your carbon footprint by using renewable energy.
• Cutting-edge technology & reliability — ‘latest-generation’ panels and the renowned hybrid inverter (Sofar Solar) guarantee efficient and sustainable energy production.
• Attractive economic potential (in the long term) — the estimated output (≈ 9,790 kWh/year under reference conditions) indicates significant potential for ‘free’ electricity in the long term.

Selected from the latest technologies, this panel offers unrivalled efficiency.

As part of our commitment to regulatory compliance and environmental responsibility in Belgium, we would like to inform our customers that the purchase of a Sofar Solar BTS 5K battery is subject to a mandatory environmental levy.
An amount of€144.50 excluding VATmust be added for each battery purchased, as a direct contribution to Bebat, the organisation responsible for managing batteries and accumulators in Belgium. This measure is in accordance with current Belgian environmental legislation.
Important:When purchasing a lithium battery, please add the corresponding product "Sofar Solar BTS 5K Bebat Environmental Levy" according to the number of batteries you are ordering. Otherwise, we will recalculate and invoice the amount after the purchase.
This tax applies only to Belgian customers.
• This kit is well suited to a variety of scenarios:
• Detached house connected to the grid — to cover a large proportion of electricity needs (lighting, appliances, sockets, etc.) whilst reducing bills.
• Reduced dependence & security in the event of a power cut — the lithium battery can provide backup power if the grid fails, to supply essential circuits.
• Second home / holiday home / isolated property — ideal if the property is not occupied all year round or if the grid connection is expensive or unreliable.
• Use with moderate or standard appliances — the system is suitable for ‘normal’ consumption (but may not be suitable for very intensive uses such as large resistance heaters or heavy air conditioning).
• Transition to a larger / scalable system — the kit is a good starting point for those wishing to try out self-consumption and potentially expand later (adding panels, a battery, etc.).
• “Optimised” & eco-friendly consumption — for people who care about the environment and wish to use clean energy, reduce their carbon footprint, or prepare for energy self-sufficiency.
