Photovoltaic Systems
Are you looking for the ideal solution to control your energy bill, reduce your ecological footprint or make your home more profitable?
Invest in a photovoltaic system!
It's the first step towards the energy transition and allows you to control all or part of your electricity bill.
How do solar panels work?
When solar panels are installed on your roof or in your garden, they absorb ambient light and transform it into direct electrical current. This direct current is then converted into alternating current by an inverter to power your lighting and electrical appliances.
If your photovoltaic system generates more electricity than you consume, the excess is transferred to the electricity grid.

Photovoltaics and EPB certificate
When you have your property assessed by an EPB certification body, the overall energy consumption of the building is taken into account. The certification body collects a series of data for this purpose, based on five specific indicators. These indicators all have an impact on the theoretical annual consumption of your building. By pooling this data, a so-called EPB certificate is generated.
This certificate offers the possibility to compare the energy performance of buildings on the market in an objective way.
Thus, among the specific indicators used in the preparation of the EPB certificate is the category "Use of renewable energy". This category detects and evaluates the presence of systems using renewable energy and/or producing electricity, including solar photovoltaic installations.

Tigo: TS4-A-O Optimizer
Why Tigo Optimizers?
Solar panels connected in the same string operate in series and therefore carry the same electrical current. When one panel is affected by shade, dirt or a different orientation, it can restrict the current and reduce the production of the entire string.
To minimise these losses, we install Tigo optimizers on panels that are exposed to a significant risk of shading or mismatch. Each optimized panel can operate more independently, allowing the rest of the string to continue producing closer to its full potential.
- Maximises the energy production of each optimized solar panel
- Reduces losses caused by shade, dirt, different orientations or panel mismatch
- Can be installed selectively only on panels where optimisation is needed
- Supports solar panels with a power of up to 700 W
- Compatible with thousands of inverter models from more than 50 brands
- Supports rapid shutdown for improved system safety
- Simple and fast installation
- IP68 protection for reliable outdoor operation

Eastron: Smart Energy Meter
Why Eastron?
A smart power meter measures the electricity flowing between the building and the public grid in real time. It tells the inverter whether the installation is importing electricity or exporting excess solar energy.
This information is essential when a battery is connected to a hybrid inverter. It allows the inverter to decide when the battery should charge or discharge, maximise self-consumption and avoid charging the battery while the building is already exporting or discharging while electricity is being sent to the grid.
- Compatible with Solis inverters
- Compatible with 3 × 230 V and 3 × 400 V electrical networks
- Bidirectional measurement of grid import and export
- Uses external current transformers for higher-current installations
- Measures voltage, current, power, energy and power factor
- RS485 Modbus communication with the inverter
- MID-certified measurement
- Reliable monitoring for residential and commercial installations

Solar Panels, Photovoltaic Panels, Thermodynamic Panels: What is the Difference?
Solar panels is a more generic terms of two types of panels:
a) Solar thermal panels for producing domestic hot water
b) Photovoltaic solar panels that produce electricity.
a) Solar thermal panels can be thermodynamic, or water based and they produce domestic hot water. Delex Belgium does have solar thermodynamic panels and heat pumps in the portfolio, feel free to contact us at: contact@delex.eco for an offer!
b) Photovoltaic solar panels (also abbreviated PV panel) are based on silicon solar cells, and they produce electricity. There are several types of photovoltaic solar panels, mostly used today are the monocrystalline which offer best price/kW ratio. Here is a short description of them:
- Monocrystalline
- Polycrystalline
- Solar film
Monocrystalline PV panels:
A single pure silicon crystal that has been divided into numerous cells is used to create these solar panels. Those panels are usually black and are the ones that Delex uses both for industrial and domestic installations. They are the most efficient, long lasting, and best looking of the 3 types but also the most expensive. They are the most common type on the market nowadays.
Polycrystalline PV panels:
As the title infers, these come from diverse silicon precious stones rather than one, giving them a light blue color. They are less space-effective, have lower warm resistance and are less productive in high-temperature situations but are cheaper to produce. Those panels are losing ground in favor of monocrystalline ones and Delex does not use them anymore.
Solar Film panels:
Thin-film panels are characterized by very fine layers and are thin enough to be flexible. Each panel does not require a frame, making it lightweight and easy to install. They come in a variety of sizes, depending on your needs. However, they are almost twice as less efficient than crystalline ones. Delex does not offer this type of panel.
