What's Watt-peak?
What does Watt-peak mean?
Watt-peak is a unit of measurement that indicates the maximum amount of energy a solar panel can generate. The higher this number, the more power the panel can generate. In practice, your solar panels yield less than the indicated Watt-peak. This property indicates the performance of a panel under the best circumstances. This means the panel faces South and that the ambient temperature is 25°C, for example. These circumstances aren't realistic in practice. On your roof, you're dependent on the number of hours of sunshine and the incline of your roof.
From Watt-peak to kilowatt hour
What does a solar panel generate for you in terms of power? For this, we look at the kilowatt hours (kWh). This indicates the number of watts you generate or consume within 1 hour. On average, 1Wp generates about 0.83kWh in the Netherlands. For a 410Wp solar panel, you multiply this amount by 0.83. This means you generate 340kWh.
How much Watt-peak do you need?
When you choose a solar panel with a higher Watt-peak, you pay more or it. On the other hand, the panel performs better, lasts longer, and has a higher yield. How much Watt-peak do you need to cover your annual consumption? Let's say you consume 3000kWh per year. You multiply 3000kWh by 0.83kWh. This means your solar roof needs to generate 2490Wp.
Need help?
It's not beneficial if your solar roof generates too little or too much. Not sure which panels are the best for you? Ask for an advice appointment without obligations. During this appointment, our advisors take a look at your consumption and they'll ask about your plans for the future. Want to buy a heat pump or an electric car soon, for example? We'll include these wishes in your advice. That way, you choose a solar roof that best suits your situation.
