Frequently Asked Questions
How often should I clean panels?
Every 2–3 months in cities. Monthly during dry season or near construction.
Can rain clean my panels?
Partially. Rain removes loose dust but not bird droppings or sticky pollution.
Do lithium batteries need maintenance?
Minimal. Check connections every 6 months. Keep ventilation clear.
When should I call a technician?
Error codes, sudden output drop >20%, unusual sounds, burning smell — call immediately.
Is maintenance covered by warranty?
Equipment warranty ≠ maintenance. Some installers offer maintenance packages.
Common Mistakes to Avoid
Never cleaning panels
15% output loss from dirt alone. Cleaning is the highest-ROI maintenance task.
Using pressure washer on panels
Can crack cells and damage seals. Use gentle water flow only.
Ignoring error codes
Small faults become expensive repairs. Address alerts within 48 hours.
