Why Choose Plug & Play?
Simple – Set up in minutes on a balcony, terrace, garden, or flat roof.
Accessible – Ideal for renters, small households, and budget-conscious users.
Affordable – Order online, get it delivered, plug it in, and start saving.
What Does It Cost?
Prices have dropped significantly. A 400–450 Wp plug & play kit now ranges from €540 to €740 excl. VAT. While more expensive per kWh than traditional solar systems (around €1,150/kWp), the ease of use makes it an attractive alternative.
What Can You Save?
A 400 Wp system in Belgium can generate around 380 kWh per year, which equals 10–15% of a typical household’s annual usage. This can save you up to €115 per year (at €0.30/kWh, assuming full self-consumption).
Safety and Requirements
Mechanical Safety: Secure panels firmly to prevent wind damage.
Electrical Safety: Always use weather-resistant plugs and outdoor cables.

Compliance: Ensure your kit is CE-certified with an EU declaration of conformity.
Lifespan: Expect 20–25 years of use — not a lifetime investment.
What About Batteries?
Plug & play batteries allow you to store excess solar energy for later use. While traditional home batteries are still expensive, some plug & play models can be worthwhile depending on your usage, system size, and energy rates.
