Before you run the numbers, here are the basics.
Modern solar panels are warrantied for 25 years, but many last 30-35 years. They degrade about 0.5% per year, meaning after 25 years they still produce roughly 87% of their original output. The inverter typically needs replacing once (around year 12-15), costing about EUR 1,000-2,000.
Yes. The Netherlands gets about 1,000 kWh per kWp per year. Germany and Belgium are similar. Panels work with diffused light too, not just direct sunlight. Most Northern European systems pay themselves back in 6-9 years and then generate free electricity for 15+ more years.
It depends. If you have or plan an EV, a battery makes great sense since you can charge at night with your own solar power. Same if energy independence is your priority. Purely financially, batteries are not yet break-even in most European countries, but prices drop about 15% per year. Our calculator factors this in for your specific situation.
Most European countries offer some form of solar incentive. The Netherlands has the "salderingsregeling" (net metering) phasing out gradually. Germany has feed-in tariffs. France has tax credits. Spain removed the "sun tax" and now offers subsidies. Our results include a note about subsidies available in your country.
Research consistently shows solar panels add 3-4% to home value. A typical EUR 8,000 system on a EUR 350,000 home could add EUR 10,000-14,000 in value. They also improve your energy label, which matters increasingly for mortgage terms and resale.
These factors determine how much sunlight your panels will capture.
