Busted: Quashing Four Commons Solar Myths Floating Around Germany warnings: FALSE, STRONG
Unfounded Assertions Surrounding Photovolataic Energy: Debunked
Let's separate fact from fiction when it comes to solar power in Germany. Energy expert Thomas Zwingmann from the North Rhine-Westphalia Consumer Center is here to debunk four common myths about photovoltaic (PV) systems.
Myth 1: Separate from the GridNot quite: Although a PV system with battery storage can significantly reduce dependence on standard electricity, it won't make you entirely independent. Your annual household electricity consumption will always exceed the generated solar power, necessitating some grid power. Achieving 100% self-reliance would be technically complex and economically unfeasible, requiring a seasonal storage system like hydrogen [Consumer Center (2022)].
Myth 2: Battery Storage is a MustNope: A PV system can be financially worthwhile without battery storage. The decision to include storage in your setup depends on individual electricity consumption and costs. Homeowners should determine if storing excess energy will provide a return on investment.
Myth 3: South-Facing Roofs Reign SupremeAlmost: A south-facing roof will generate the most power, as it receives the most sunlight. However, east-west facing roofs should not be dismissed, as they start producing electricity earlier in the morning and later in the evening. This afternoon-evening peak period aligns with when many households consume electricity, making east-west systems a clever choice for energy consumption adjustment [Consumer Center (2022)].
Myth 4: Plug-In Solar Devices are Jack-of-All-TradesWrong: Plug-in solar devices are a fantastic choice for providing your own clean energy, but keep in mind, their maximum nominal power is about 800 watts. Although suitable for covering your home's basic load, they cannot power larger appliances like coffee makers, as they require more power around 2000 watts.

- Thomas Zwingmann, an energy expert from the North Rhine-Westphalia Consumer Center, explains that misconceptions about solar power in Germany need to be addressed.
- One common myth debunked by Zwingmann is that a PV system can make a household entirely independent from the grid, but annual electricity consumption will always exceed generated solar power, necessitating some grid power.
- He also clarifies that while a PV system with battery storage can help reduce dependence on standard electricity, the decision to include storage in the setup depends on individual electricity consumption and costs.
- Zwingmann advises that while south-facing roofs generate the most power, east-west facing roofs should not be overlooked as they produce electricity earlier in the morning and later in the evening, aligning with when many households consume electricity.
- Regarding plug-in solar devices, Zwingmann indicates that while they are great for providing clean energy, they have a maximum nominal power of about 800 watts, limiting their ability to power larger appliances like coffee makers.
