In Brussels when you produce more energy than you consume, it is fed back into the grid. You must then pay injection rates for it and repurchase that re-injected energy at night.
That's why Perceval has updated the solar energy solutions. Avoid paying taxes to re-inject your energy and losing the energy you produce for your home or business. Learn more below about Perceval’s smart storage solution.
Your energy is yours!

Normally in a blackout your inverter is put on standby and no longer produces energy, even if there is sun.
But Perceval’s solution has done it differently, and provides you with an emergency power supply as long as you have sun or battery power.
Our experts use their creativity and experience to bring you our smart solar energy storage solution.
With Perceval's Solar Energy Solution you can store your energy and save much more.
Just replace your inverter and batteries for ours, and you will have:
Based on theoretical assumptions and mathematical models:
Your old inverter can be worth money.
We recycle your inverter and give you a discount on the new one.

In the case of solar system installation, a "prosumer" is a person who both consumes and produces electricity. These individuals generate their own solar power, sell the excess energy back to the grid, and then repurchase it.
Because there is usually a mismatch between the peaks of production and consumption, you may end up returning and repurchasing energy rather than actually consuming it. When the panels produce energy from sunlight, the house is often empty. At night, when everyone is at home, there is no more sunlight to produce energy, and consumption is higher.
Selling the excess energy is not a good bargain since you must pay a fee to return this energy to the grid and then repurchase this energy at the usual electricity rates.
The ideal is that you consume only the electricity from your panels. That is why we created our solution, so that you may increasingly use the energy you have produced rather than consume it from the grid at ever higher prices.
We first check the compatibility of your installation with our hybrid inverters. If positive, we will replace the inverter and batteries.
We believe in the circular economy. We offer a trade-in bonus for your old inverter*. The price of the trade-in is as follows:
Trade-in price
(considering the age of your previous inverter)
1 year 100 eur
2 years 100 eur
3 years 75 eur
4 years 75 eur
5 years 50 eur
+5 years 0
*To qualify for this reduction, the inverter must be your exclusive property, free of any encumbrances or legal impediments.
The total amount is divided into 3 phases:
*To verify the compatibility of certain technical criteria of your installation with the new inverters and batteries.
6% on all buildings more than 10 years old. Buildings less than 10 years old benefit from this rate for photovoltaic installations for a temporary period to the end of 2023.
Currently the market is experiencing supply problems. We schedule our customers according to the payment date of their deposit and try to keep them always up to date with the best indicative dates.
Our inverters have a monitoring function included. It allows you to track the useful life of your installation via an application. You must have WiFi near the inverter to benefit from this function.
Bebat's recycling premium is included in the package. It will allow you to recycle the batteries free of charge.
Increasingly often your grid connection will be used only for birds resting.
