  • The Size of Solar Panels on Roofs A Consideration for Homeowners


  • Another challenge is the need for proper system sizing and planning. Homeowners must accurately assess their energy needs to determine the number of solar panels and the capacity of the battery storage required. This process can involve a steep learning curve, and potential users are encouraged to seek guidance from professionals or consult reliable resources to optimize their systems.


  • Typically, solar panels have a lifespan of about 25 years. Over this period, they can significantly reduce electricity costs, often leading to savings that exceed the initial investment. In places with high electricity rates or abundant sunlight, the payback period for solar panel investments may be shorter, often within 5 to 10 years.


  • Bifacial solar panels are constructed with photovoltaic cells on both sides, allowing them to collect sunlight not only from the direct sunlight hitting the front but also from the reflected light on the back. This dual-sided functionality enables them to utilize both direct and diffuse sunlight, resulting in higher efficiency rates.


  • What are green credentials? ADEME (the French Environment and Energy Management Agency) defines it as “value added to a property through improved environmental performance.” It can also refer to the added value associated with the good energy performances of your home.
