Debunking Four Solar Myths: Separating Fact from Fiction
Going Solar? Just a Few Things You Should Know!
Four common myths about solar panels debunked as misinformation
Reducing electricity bills, powering your home with clean energy, and contributing to energy independence is why many people consider installing solar panels. But, there are misconceptions surrounding solar systems that can leave you scratching your head. Let's clarify four common misconceptions to ensure your solar investment pays off!
Myth 1: Solar Panels + Storage Equals Energy Independence
Sadly, not the case. A solar system with storage will provide a portion of your annual household electricity, but not enough to sever all ties with utility companies, especially during winter months and nighttime. True energy independence demands an additional, complex and economically challenged seasonal storage system like a hydrogen storage system [1].
Myth 2: Solar Panels + Storage are Necessary for Financial Viability
False. A solar system can, in fact, be financially worthwhile even without storage. However, the financial worth of a storage system depends on your household's electricity consumption and costs. If excess solar electricity can already be self-consumed without storage, a battery storage system may not be financially viable due to its high cost [1].
Myth 3: South-facing rooftops are superior
While south-facing rooftops generate the most electricity possible, east-west facing rooftops can be advantageous. East-west facing rooftops receive sunlight earlier in the morning and later in the evening allowing for greater self-consumption of electricity during times of high usage [1]. This leads to significant savings, especially when people are most at home [1].
Myth 4: Plug-in Solar Generators can power your coffee maker
Sad but true. Plug-in solar generators can produce clean energy with minimal effort, but their nominal power is limited to about 800 watts. This is enough to cover low-power appliances, such as a refrigerator, router, or alarm clock. However, a coffee maker's power requirement of approximately 2000 watts can't be met with a plug-in solar generator [2].

Consequences and Considerations
Understanding consumer myths helping you make informed decisions when investing in solar systems. While battery storage offers advantages such as energy independence,backup power, and increased savings, it also comes with high upfront costs, space requirements, complexity, efficiency losses, and safety risks. Ensuring self-sufficiency demands careful evaluation of energy needs, costs, incentives, location, and system efficiency for financial viability [4].

- The community should be informed about the misconceptions surrounding solar panels and storage systems in the renewable-energy industry, especially regarding their ability to provide complete energy independence.
- Employment policies within the photovoltaics industry could benefit from addressing the false notion that solar panels and storage are essential for financial viability, as a solar system can be financially worthwhile even without storage.
- In drafting employment policies for the renewable-energy sector, it is crucial to acknowledge that east-west facing rooftops can be advantageous for greater self-consumption of electricity during high usage times, especially during the day when people are most at home.
- A misconception that persists in the renewable-energy industry is that plug-in solar generators can power large appliances, such as a coffee maker, but their nominal power is limited to about 800 watts, making them suitable only for low-power appliances.
- Finance policies in the renewable-energy sector should take into account the high upfront costs, space requirements, complexity, efficiency losses, and safety risks associated with battery storage systems, in order to make informed decisions and optimize the financial benefits of investing in solar systems.
