Your energy use
Going electric for driving, cooking or heating? Factor that into how many panels you need now.
Advice about solar panels
- Use more of your own power during the day
- Helps toward a better energy label
- 0% VAT makes the investment even more attractive
- Use more yourself, less exposure to feed-in charges
- Keep benefiting smartly even without net metering

Solar panels can raise the value of your home and help toward a better energy label. You enjoy them today, and they remain a smart investment for later.
How many solar panels do I need? The calculation
How many panels you need depends on your power use. Look at your current annual use on your energy bill, and think ahead: electric driving, a home battery, or a growing household can all raise demand.
Planning for that now helps you avoid an install that is too small later. Bigger is not always better either. In an advice call we look at today's use and what the coming years may bring.
Solar power that fits your family
Morning coffee, laundry in between: you already did that, and it needs power during the day. With solar panels on your roof, more of that power comes from you.

Solar panels are still a smart investment in 2026. A few things are worth watching. These tips help you get the most from your own power
Spread your yield
Spread panels across roof faces. You generate throughout the day and use more of your own power.
Your data
Smart energy needs smart security. Prefer a system with its own 4G link and data stored in Europe.
Shade
A chimney or tree can slow a string of panels. Microinverters or optimizers keep the rest performing.
Inverter
The inverter is the heart of your system. Pick a strong brand with solid monitoring and clear warranty.
Net metering
Net metering ends. The more you use yourself, the less you depend on feed-in. That starts with the right design.
Maintenance
Panels need little care. Still check for dirt or leaves, and watch the app if yield suddenly drops.
How it works
From sunlight to electricity
A solar panel contains silicon cells. Sunlight knocks electrons loose in those cells, and that produces direct current (DC). The more light there is, the more power. Direct sun gives the highest output, but generation continues even under cloud.
So you do not need a heatwave. Bright but cool spring weather often gives a great result, because the cells work slightly more efficiently at lower temperatures.
The inverter does the heavy lifting
Your home and the grid run on alternating current (AC), while your roof produces direct current (DC). The inverter converts one into the other so you can use the energy at home or feed it back.
There are different types, from a central string inverter to a micro-inverter per module. Which fits depends on your roof, the number of modules and any shading.
Self-use, feed-in and storage
If you generate more than you use during the day, the surplus goes back to the grid. In the evening you draw electricity from your energy supplier again. How that exchange is settled falls under the net metering scheme, which is ending.
If you want to use more of your own generation, a home battery helps. It stores the daytime surplus for the evening, exactly when your usage peaks.
Smart energy at home
Heat pump
A heat pump draws warmth from the outside air and uses far less gas than a boiler. Your home stays comfortable, summer and winter, while you save on your energy bill.

Home battery
The sun does not only shine when you need power. With a battery you store today's energy for tomorrow morning's coffee. Or you use stored power on cloudy days and in the evening.

EV charger
Home charging is the easiest option: leave every morning with a full battery. Pair your charger with solar panels and charge on your own power.

Air conditioning
On a hot day you just want a room that feels liveable again. A fixed air conditioner cools quickly, and can top up heat in that same room in winter.

Frequently asked questions
That depends on your roof and your usage. You get a tailored quote with A-brand panels and no down payment. Request one with no obligation and you'll know where you stand within 24 hours.
Usually within three weeks of approval. Our own installers plan a time that suits you.
For many homes yes, but there is no fixed timeline. Usage, tariffs, feed-in charges and the end of net metering all play a part. We calculate it concretely in your quote.
East- and west-facing roofs produce well too. We calculate upfront what your roof can realistically deliver.
Yes. Our quote is all-in: panels, inverter and installation. No surprises afterwards.
Yes. Solar panels count in the energy-label calculation and can help toward a better label. Your existing registered label does not update by itself: if you want it refreshed, have a new label drawn up after installation.
