About Solar Panel Installer
When solar panels may not be worth it
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.
Choosing between quotes from different installers
Compare panel brand, inverter type, mounting brand, and warranty length, not just the total price. A cheap quote often skips better rails or surge protection. Ask each firm for the same panel count and orientation so the comparison is fair. Read the small print before signing.
What a solar panel installer does on site
An installer visits your home, checks the roof condition and direction, measures shade, and designs a system that fits your power use. They mount rails, attach panels, wire them to an inverter, connect to your meter, and run final tests. They also handle the paperwork for grid connection.
Types of solar panels a homeowner can choose
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.
How roof type affects the 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.
Inverter choices that change system cost
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.
Typical installation time for a home system
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.
Signs your current solar panels may need attention
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.
Common installation mistakes that hurt performance
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.
Permits and inspections required before going live
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.
