Do you crave maximum freedom, absolute safety, and want to save on your energy bills immediately? Our Duo-Power system is a professional, independent energy system built from the absolute top components on the global market. Whether you are a homeowner or a tenant, this is the most flexible and cost-effective solution in the Netherlands!
Selected World-Class Brands: The Three Pillars of Your System
Unlike the many unbranded kits on the market, we make no compromises on quality. Your system is built with components from globally recognized market leaders:
LONGI Solar Panels: As the world's largest and most respected manufacturer of monocrystalline cells, Longi is synonymous with reliability and innovation. Our panels with a silver frame offer superior heat reflection, making them more efficient on hot summer days than black-framed panels. Designed for stable power generation for over 10 years.
NEP (WiFi) Micro-inverters: A pioneer in micro-inverter technology with a global reputation. NEP is praised for its extremely low failure rate and high-quality WiFi integration. These inverters have the highest safety certifications (CE, VDE-AR-N 4105) and are IP67 waterproof. This means they are fully protected against the heaviest Dutch rain showers, storms, and dust.
KSENG Mounting System: The undisputed specialist in robust, aluminum mounting materials. KSENG brackets are corrosion-resistant and storm-proof, essential for the Dutch climate.
Why is our kit superior to "Cheap" alternatives?
The devil in solar power is often in the details. Here's why our system pays for itself faster and is safer than budget combinations:
Adjustable = More Money (+25%): Cheap kits costing €140-€180 often use simple hooks or plastic zip ties, causing the panels to hang vertically (at a 90-degree angle). This leads to efficiency losses of up to 30%. Our adjustable KSENG brackets let you choose the ideal angle, yielding up to 25% more power. That's pure profit!
Top Brands vs. B-Choice: Many cheap suppliers use unbranded panels or B-choice cells with hidden micro-cracks. Our Longi and NEP combination guarantees certified safety and stable power generation. No risk of overheating or short circuits.
Real-time WiFi Monitoring: Where cheap kits often require an unstable external adapter, the WiFi on NEP is built-in directly. Track your yield live via the free app – you don't need any extra expensive adapters (DTU).
Unlimited Freedom: Place the panels wherever you want. As long as there's a socket, you can plug them in independently.
Perfect for Tenants: Mobile, Flexible & Damage-Free
Moving is Simple: This system is as mobile as a washing machine. When moving, you unplug it, disassemble the brackets without drilling holes, and take your own power source with you to your next home.
Plug & Play: Operational within minutes without needing an installer or special tools.
Now Is the Best Time: Take Advantage of Spring!
March and April are the most strategic months to install your Duo-Power system. During this period, the number of sunshine hours in the Netherlands increases rapidly, while the panels perform at their highest efficiency due to the cooler temperatures. By starting now, you'll harness the full energy peak of spring and summer, directly shortening your payback period. Don't wait until summer; start lowering your energy bill from the first day of spring!
Calculation Model: Your Return & Environmental Impact
Save money and help the planet at the same time:
| Electricity Price (per kWh) | Annual Savings (approx.) | Payback Period | CO₂ Reduction |
| € 0.35 | € 260 – € 290 | ~ 1.8 years | ~ 320 kg per year |
| € 0.40 | € 300 – € 330 | ~ 1.6 years | ≈ equivalent to planting 16 trees per year |
| € 0.45 | € 340 – € 370 | ~ 1.4 years | ≈ equivalent to planting 16 trees per year |
