What does 10 kWp mean, and how much electricity can it produce in practice?

10 kWp indicates the maximum power capacity of your solar panel system: 10 kilowatt peak. This means that the system – under ideal conditions – can deliver up to 10 kilowatt-hours (kWh) per hour when the sun is high and hits the panels optimally. It is not the actual production over time, but the maximum output at that moment.

Annual production: What do you actually get out of 10 kWp?

A 10 kWp system in Denmark will typically produce between 8,000 and 10,000 kWh annually, depending on the roof's location, slope, shadows, and geographical location.

Summer vs. winter – large differences in production

In July, a 10 kWp system can produce up to 1,500–3,000 kWh in one month. In December–January, production is typically only 150–300 kWh. This corresponds to a factor of 10–20 in difference – and underscores the need for intelligent control and a battery if you want to utilize the surplus efficiently.

EcoRay's technology makes the difference

At EcoRay, we use UV-coated, high-performance solar panels that are particularly sensitive to diffuse light. This means that your system produces significantly better in cloudy weather – even in the winter months – than traditional panels from just 5–10 years ago. The technology has improved significantly.

A realistic example:

A typical Danish detached house uses approx. 8,000 kWh per year. A 10 kWp system will in most cases be able to cover the entire consumption – and provide surplus electricity in the summer half-year, which you can sell or store with a battery. In the winter months, you can – with a battery – still expect to save 40–60% on your electricity bill.

Conclusion:

10 kWp = up to 10 kWh per hour at peak. Annual production: typically 8,000–10,000 kWh in Denmark. Large difference between winter and summer – therefore, intelligent control and a battery are crucial. With EcoRay's technology, you get state-of-the-art performance, even in diffuse light conditions.
