After using a solar energy system for a year, customers typically encounter some issues:

Decreased Power Generation Efficiency:

Some customers may find that the efficiency of solar panels declines over time, especially due to dust, dirt, or shading.
Suggestion:

Opt for top-tier brand A-grade components and ensure regular maintenance and cleaning. The number of components should match the optimal capacity of the inverter.

Energy Storage Issues:

If the system is equipped with energy storage, customers might notice insufficient battery capacity to meet peak electricity demands, or that the batteries degrade quickly.
Suggestion:

If you want to increase battery capacity after a year, note that due to rapid upgrades in battery technology, newly purchased batteries cannot be connected in parallel with older ones. Therefore, when procuring the system, consider the battery’s lifespan and capacity, and aim to equip enough batteries in one go.
