Clean panels every 6 to 12 months to remove dust, leaves, and bird droppings. Check inverter logs monthly for error codes. Inspect mounting hardware yearly for rust or loose bolts. Trim nearby branches that grow into the panel area. A professional inspection every 2 years is also recommended.
Improper grounding, undersized DC cables, panels mounted in heavy shade, or rails not sealed correctly lead to long-term problems. Loose MC4 connectors cause arcs. Mixing different panel brands on one string lowers output. Poor roof flashing is the most common source of leaks after installation.
Tile, metal, and asphalt shingle roofs each need different mounting hardware. Tile roofs often require tile replacement brackets. Metal roofs can use clamps without drilling. Flat roofs need tilted frames. Roof pitch, usually between 15 and 40 degrees, also changes mounting time and parts.
Heavy shade, a north-facing roof blocked by buildings, or a rental with landlord limits can make payback long. Old roofs needing repair soon also raise the cost. Ask the installer for a shade analysis and an estimated yearly output before you sign any contract.
Panels are usually monocrystalline silicon rated 400 W to 500 W each. Inverters come as string, micro, or hybrid types. Rails are aluminium, brackets are stainless steel, and cable is UV-rated double insulated. Your installer should list every part before work begins.
Loose roof brackets cause leaks after heavy rain. Poor sealing around cable entries lets water reach the inverter. Shading from new trees or buildings lowers output fast. Bad wiring trips the breaker under load. Always ask the installer how they prevent each of these issues.
Panel product warranties usually last 10 to 25 years, while performance warranties promise at least 80 to 85 percent output at year 25. Inverter warranties range from 5 to 12 years. Workmanship warranties from the installer typically run 2 to 10 years. Get all terms in writing.
Falling power output on the inverter display, yellow or brown discoloration on panel surfaces, cracked glass, loose rails after storms, or rust on mounting hardware all signal trouble. Error codes on the inverter, like isolation faults or ground faults, also need a technician visit.
Most residential jobs use 60-cell or 72-cell crystalline silicon panels. Monocrystalline panels have higher efficiency, around 19 to 22 percent, while polycrystalline sit closer to 15 to 18 percent. Thin-film panels are lighter but need more roof space for the same power output.
Most panels carry a 25-year performance warranty. Inverters usually last 10 to 12 years. Mounting hardware often has a 10-year product warranty. Ask the installer for a yearly output check during the first 5 years to catch early faults before they grow.
