Solar panels from The Sustainable Boys

Cheap, green power

The question is not whether solar panels are interesting, but when you start taking advantage of them. While the energy market remains unpredictable, solar panels give you certainty: fixed, low costs and an investment that pays for itself. Even after the abolition of the net-metering scheme.

With the latest generation of panels, you get the maximum return from the sun. You lower your monthly expenses from day one and put your home on the market stronger with a better energy label.

Custom sustainability advice

Every home is different. That’s why we always start with a personal consultation in your home. This results in tailored sustainability advice: a plan that fits your roof, your energy consumption and your future plans. Will you soon want to charge your electric car or store electricity in a home battery? Then we will ensure that your system is prepared for this now.

How many solar panels do I need?

The size of the installation depends on your energy consumption and living situation. Our advisors look at your current consumption as well as your plans for the future (for example, expansion with a charging station or home battery). This way you get a system that is perfectly tailored to your needs, so you never pay too much.

Converting energy

Inverter

The heart of your installation

The solar energy generated is not yet directly usable in your home. The inverter converts it to alternating current suitable for your appliances. A good inverter is crucial for the efficiency and lifetime of your installation. That’s why we only work with reliable brands (such as Enphase) that provide quiet, efficient and safe inverters.

Financing solar panels

pay 0 euro vat

Solar panels are a smart investment for the future, but often require financial choices. There are no subsidies for purchasing solar panels. Since 2023, however, the 0% VAT rate does apply. This makes a significant difference in costs. In addition, there are several ways to finance your solar panels.

Buying solar panels without savings

Solar panels are an investment that will pay for itself, but the purchase cost can be a hefty expense. It’s understandable that you’d rather not use your savings. Fortunately, there are several financing options that will help you make this step affordable.

We will be happy to tell you more about the financial options and see what best suits your situation. If you wish, we will also help you apply for the scheme. How convenient.

Guarantees for worry-free use

Solar panels are a long-term investment. It’s not just about high-quality panels from a reputable brand, but also about warranties that protect you for the long term. With The Sustainable Boys, you choose products with long warranties that provide security: on quality, on performance and on installation.

Product warranty solar panels

This warranty covers material and manufacturing defects of the panels themselves. Depending on the manufacturer, this usually runs from 10 to as much as 25 years.

Product warranty inverters

Inverters often have a shorter lifespan. The standard manufacturer’s warranty varies between 5 and 10 years, depending on the brand and type.

Product warranty optimizers

For systems with optimizers, you often benefit from longer warranty periods. For example, SolarEdge offers a 25-year warranty on their optimizers.

Power guarantee solar panels

Manufacturers guarantee that your panels will still provide at least 80-85% of their original output after 25 years. So you can be sure that the yield will remain at the same level.

Solar panel installation warranty

In addition to product warranties, The Durable Boys gives you a 20-year warranty on installation. This assures you of a safe and competent installation.

Offsetting with solar panels

With solar panels, you generate your own electricity. If you do not use this power immediately, you will feed it back into the grid. Thanks to the net-metering scheme, you can offset the power you supply back against the power you later take from the grid. This allows you to get the most out of your solar panels, even when the sun is not always shining.

The government has decided to abolish the net-metering scheme from 2027. This means that it will become even more important to use or store as much of your own electricity as possible directly, for example with a home battery or smart charging station.

Frequently Asked Questions

Reviews

01 How does netting actually work?

Very simple: the electricity you feed back is offset against what you consume. Up to and including 2026 this can still be done in full, after that the scheme will change.

02 Until when can I still net up?

The scheme will remain in place until Dec. 31, 2026. From 2027, net-metering will stop and you will receive a feed-in fee for power you send into the grid.

03 What will I get for my returned power later?

After 2027, you are guaranteed a reimbursement of at least 50% of the calving rate. This is set by law until the end of 2029. After that, the energy supplier determines the amount, but it must remain “reasonable.

04 How high are the fees in 2026?

This varies by supplier: on average they are between€0.02 and €0.19 perkWh. So it pays to compare providers carefully.

05 What are feed-in charges?

More and more energy suppliers are charging fees when you feed power back. Consider processing or imbalance charges. Pay attention to this when choosing your contract; sometimes these costs are low or even zero.

06 So how do I get the most out of my solar panels?

Use as much power as possible when the sun is shining. Think about washing clothes or charging your car during the day. A home battery or dynamic energy contract can enhance this effect.

07 Will solar panels still be profitable if net-metering stops?

Yes. You still benefit from full net-metering until the end of 2026. After that the investment remains interesting, especially if you are smart about your own consumption or add a battery.

08 What should I pay attention to with my energy contract?

Pay attention not only to the electricity rate, but also to:

  • amount of the feed-in fee
  • any feed-in charges
  • flexibility (fixed, variable or dynamic contract)
