Following the Sun: How to Plan a Solar System and Maximise Its Output. With Solar Energy Expert Filippo Presti.

Episode description

Install solar panels on your roof and watch your electricity bills fall? It is rarely that simple. What happens if your roof needs renovating in five years? When does a solar installation really pay off, and why is the investment often overlooked in property valuations?

In episode 3 of Grundriss fürs Leben, Daniel Schweizer speaks with Filippo Presti about solar energy for single-family homes. Filippo heads the solar division, has an electrical engineering background, and is open about the situations in which he would advise against installing a solar system. An episode for anyone planning to build, renovate or buy a property with an existing solar installation.

In this episode, you will learn:

• What is the difference between solar thermal systems and solar photovoltaic (PV) systems, and why is PV now the more common choice?

• Why your roof should be assessed before installing solar panels, and when an energy-efficient roof renovation should come first.

• When a solar system pays for itself, and why the typical payback period of 8 to 15 years depends more on your energy consumption than on the roof itself.

• Why a solar system must shut down during a power outage, and what is needed to keep your home supplied with electricity.

• How energy-independent a single-family home can realistically be, and what role battery storage and energy management systems play.

• Why property valuation tools often overlook investments in solar energy, and why keeping the relevant documentation can pay off when selling your property.

• When Filippo would clearly advise a property owner against installing a solar system.

   

Myth or Fact?

Daniel and Filippo examine three common claims:

• Are solar systems really maintenance-free?

• Do more solar panels always mean better financial returns?

• Do you absolutely need a south-facing roof?

Filippo’s advice: Compare solar installation quotes on a like-for-like basis. An offer that looks inexpensive at first can become much more costly once additional charges and changes are factored in.
