Three Common Misconceptions on Solar Energy Debunked
Smart solar PV and battery storage systems are revolutionising how businesses control energy costs and meet sustainability targets. While 406 GW of solar capacity have already been installed in Europe as of 2025, persistent misconceptions continue to hold more companies back from exploring these sustainable solutions. At Wewise, we are dedicated to dispelling these myths and revealing the real benefits solar PV panels can offer businesses across Europe.
Solar and Storage Systems only work when it's sunny
It's a common belief that solar energy systems only work when it’s sunny. However, in reality, smart solar and storage systems operate 24/7 by intelligently balancing energy use for smooth, cost-effective performance.
At night and early morning, when electricity prices are low, the battery charges using off-peak grid power, preparing to supply energy during high-demand, costly periods later in the day. From morning to afternoon, solar panels generate peak power around midday, fully charging the battery while meeting on-site electricity needs and reducing grid reliance. Even on cloudy days, solar energy yields usable results that help save money.
In the evening, as demand rises, the battery discharges stored power to support the site and the grid, earning service payments and lowering electricity costs by avoiding expensive grid power. This continuous cycle enables smart solar and storage systems to provide savings whilst potentially generating additional income for your business.
The upfront costs are too high and not worth the investment
Many SME’s in Europe believe that the high upfront costs of solar PV systems put them out of reach for their business. While there can be an initial investment, it’s important to focus on the immediate economic benefits of electricity savings. By significantly lowering energy bills and reducing reliance on the national grid, solar panels enable businesses to recover their costs and achieve valuable savings over time.
Financing options are also available that eliminate upfront costs for your business while locking in favourable energy prices for a set period, protecting you from market volatility. One such option is a Corporate Power Purchase Agreement (CPPA), a contract between a business and a renewable energy generator, where the business agrees to purchase electricity at a fixed price for a set term. This arrangement supports renewable energy projects, ensures a stable and cost-effective energy supply, reduces carbon footprints, and enhances brand reputation by demonstrating a clear commitment to sustainability.
Solar panels have a short lifespan
Some businesses worry that solar panels have a relatively brief lifespan and will need frequent replacement, but on the contrary, thanks to technological advancements and the use of durable materials, modern solar panels are designed to last.
High-quality panels typically come with warranties of 25 years as standard, with some even offering 30 years, underscoring their reliability. Their robust construction ensures long-term performance, providing businesses with a dependable energy source and meaningful cost savings over time.
By understanding the truths behind the misconceptions about solar energy, you can make smarter, more confident energy decisions. Investing in smart solar and battery storage systems not only benefits your business financially but also strengthens your positive impact on the environment.
