How your roof actually
makes power.
Sun hits the panels. Panels make DC. An inverter flips it to AC. Your house drinks it. The grid catches the rest. That’s the whole story. Below: the four spots that quietly break, and why detach & reset is the moment we catch them.
Sun → Roof → House.
Silicon cells under glass. Each panel makes about 400 W of DC at peak sun.
Translate DC into the AC your house and grid speak.
AC enters your home electrical panel. Lights, AC, fridge run on solar first.
Anything you don't use flows back to the grid for credit.
Four break points nobody warns you about.
Solar lasts 25+ years on paper. In Arizona heat, dust, and monsoon, four parts wear faster than the marketing brochure said.
Microcracks in the cells
Hailstorms, dropped tools, or thermal stress can fracture the silicon under the glass. You can’t see it. Production just slowly drops.
When panels are off the roof in our hands, we infrared-scan and visually inspect every one.
MC4 connectors corrode
The little plug-and-play connectors between panels collect dust and moisture. They arc, get hot, and eventually fail.
During reset we replace any corroded connector instead of bolting them back to a fresh roof.
Mount seals leak
The flashing around each roof penetration is the #1 cause of solar-related leaks. Most fail within 7-10 years in AZ sun.
During D&R we re-flash every penetration on the new roof with high-temp underlayment.
Inverter is past prime
Microinverters are rated 12-15 years. String inverters even less. If yours is 8+ years old, it’s producing 5-15% under spec already.
During reset we pull diagnostics. If the inverter is failing, you replace it now while the panels are off, not later.
D&R is the only moment all four are exposed at once.
Once panels go back on, you don’t see them again for years. Detach & reset is the once-a-decade window where the panels are in our hands, the wiring is exposed, and the roof is bare. Skipping the inspection now means catching problems on a $5K service call later.
