Frequently asked questions from homeowners

Is a solar system still worth it today?

Many countries reduce the feed-in rates guaranteed by the government every year, and in some cases, the rates are adjusted monthly for new systems. Once installed however, systems will enjoy between one and 20 years of guaranteed feed-in rates. This along with the use of high-quality Delta inverters ensures high investment security, since the reduced system prices of recent years mean that your own photovoltaic system will pay for itself in just a few years and begin to generate profits. Many people allow themselves to be unsettled by political discussions. Don't let yourself be swayed however and secure your environmentally-friendly, self-produced energy now. Your solar installer will be pleased to consult with you regarding your profitability assessment.

What size photovoltaic system should I have?

Every photovoltaic system is unique. The size and orientation of the roof, as well as other on-site circumstances will determine the optimal size for your system.
