Solar Panel Blunders: Four Common Errors to Avoid When Installing Photovoltaic Systems
The Consumer Center, a trusted resource for consumer advice, has shed light on some common misconceptions about photovoltaic (PV) systems and battery storage. Here's what you need to know.
The Profitability of a Power Storage System
The Consumer Center emphasizes that the profitability of a power storage system depends on a household's electricity consumption and electricity costs. While the purchase costs for a power storage system are high, efficient use of solar power can help offset these costs by reducing electricity bills.
Misconceptions About Photovoltaics
Misconception One
Contrary to popular belief, a PV system, even with battery storage, can only cover a portion (25-90%) of a household's electricity needs. The Consumer Center clarifies that a PV system is financially worthwhile without a storage system.
Misconception Two
Photovoltaics does not necessarily pay off with a battery storage. The Consumer Center advises that the decision to invest in battery storage should be based on individual energy consumption patterns and local electricity costs.
Misconception Three
An east-west facing photovoltaic system does not generate approximately 80% of the solar yield compared to a similar south-facing system. East-west facing panels offer certain advantages, such as more balanced energy generation across the day, but they typically produce slightly less total energy compared to south-facing panels.
Misconception Four
Plug-in solar devices are not capable of operating high-power appliances like coffee makers exclusively with solar power. These devices are designed to consume electricity directly for appliances like refrigerators, making them a good option for tenants looking to generate their own electricity without much effort.
Efficient Use of Solar Power
To achieve efficient use of solar power, it's essential to understand one's needs and choose suitable applications for photovoltaic technology. For instance, east-west facing roofs receive sunlight early in the morning and late in the evening, allowing more electricity to be self-consumed and reducing the electricity bill accordingly.
The Consumer Center NRW provides further tips and information on the topic of photovoltaics at their advisory center in Dinslaken on Duisburger Street. By understanding the facts and debunking misconceptions, homeowners can make informed decisions and maximize the benefits of solar power.

- In the discussion about the profitability of a power storage system, it's evident that the finance industry plays a significant role, as the affordability of such systems is contingent upon electricity costs and consumption, which are financial factors.
- The integration of renewable energy sources, such as photovoltaic systems, in the energy industry is not solely reliant on technology advancements but also on the understanding of energy consumption patterns and local electricity costs, thereby necessitating the involvement of the finance sector to efficiently fund these projects.
