A plug & play solar panel can now be bought for a few hundred euros. You place it on your balcony, roof, or in the garden, plug it into the socket, and you're done: you immediately start generating your own electricity. But what does it really yield? And how quickly do you earn back such a set?
We calculate it for you using our 800W plug & play set, available in our webshop for €499 including VAT.
What is a plug & play solar panel?
As the name suggests, a plug & play solar panel is a system that you can connect without an installer. Our set consists of two solar panels of 450W each, connected to a micro-inverter with an output power of 800W. This included micro-inverter converts the generated direct current into usable alternating current for your home.
All you need is a free power socket, preferably on a separate circuit. No hassle with installations – although we can certainly help you with that if desired.
How much electricity does an 800W set generate in Belgium?
In a Flemish garden or on a south-facing balcony, you can expect an average of about 1,000 to 1,100 kWh per kWp per year. For an 800W set, this means an annual yield of approximately 700 to 800 kWh.
Please note: plug & play systems are usually not linked to the digital meter for grid feedback. This means that you only save on the electricity you consume at that moment. Think of appliances such as the refrigerator, freezer, router, or using the washing machine and dishwasher at strategic times.
For a realistic calculation, we assume 630 kWh of effective self-consumption per year.
What does that yield in euros?
The average electricity price for households in Belgium is currently around €0.35 per kWh (depending on supplier and region).
With an annual self-consumption of 630 kWh, you therefore save:
630 kWh x €0.35 = €220.50 per year
| Year | Generated electricity (kWh) | Savings (€) |
|---|---|---|
| 1 | 630 | €220.50 |
| 5 | 3.150 | €1,102.50 |
| 10 | 6.300 | €2,205.00 |
| 25 | 13.125 | €4,593.75 |
Payback period and profit
The purchase price of the set is €499. With an annual saving of approximately €220.50, you will earn back your investment in just over 2 years.
After that, everything is pure profit.
With a warranty of 25 years on the panels and 12 years on the inverter, you can expect a net profit of approximately €1,700 during that period alone. If the panels last 25 years – which is perfectly achievable with proper maintenance – your total profit will amount to almost €4,100.
Conclusion
An 800W plug & play solar panel set is an accessible, smart investment to generate your own energy and permanently reduce your electricity bill. For €499, you're set – without an installer or technical interventions. And within a few years, you will have fully recouped your purchase.
