String inverters are the cheapest and work well when panels share the same angle. Microinverters or power optimizers cost more but let each panel work alone, which helps when shade hits part of the roof. Ask which option the installer includes and why.
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.
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.
Older systems lose output after 15 to 20 years. Watch for yellowing panels, loose brackets, or inverter error codes on the display. A sudden drop in your monthly kilowatt-hour reading also suggests a fault. Get a professional test before replacing parts you may not need.
Ask for the brand of panels, inverter, and mounting hardware. Request a copy of the warranty for parts and labour. Confirm the installer holds an electrical licence and public liability cover. Ask how they handle roof penetrations and who signs off the final inspection.
Working at height and connecting to the mains grid are serious tasks. A licensed electrician must sign the install. Most local councils require a building notice before panels go on the roof. After fitting, an inspector checks the wiring before the grid operator turns the system live.
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.
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.
A standard 6 to 10 panel residential system takes 1 to 3 days on the roof. Wiring, inverter setup, and grid inspection add 2 to 6 weeks of waiting because the local utility must approve the connection. Total project time from contract to switch-on is often 4 to 8 weeks.
Most locations require a building permit for roof mounting and an electrical permit for wiring. After the install, a building inspector checks the mounting, and the utility sends a representative to approve grid connection. Your installer should manage both permits and schedule both inspections.
