Buying a solar power system can be straightforward, but some common mistakes tend to cause issues later on. One is focusing only on panel price rather than overall system suitability, which can lead to poor performance for the property. Another is overlooking roof condition, shading, or orientation, all of which affect generation but are sometimes considered too late. Some buyers also underestimate future electricity use, especially if they plan to add heat pumps or electric vehicles.
Problems can also arise from not understanding warranties, performance estimates, or the role of system components like inverters and batteries. In the UK, failing to use an MCS-certified installer can create complications with certifications and documentation. These issues are usually avoided by taking time to understand how systems are designed, asking clear questions, and comparing proposals based on long-term value rather than upfront cost alone.
