Important RoofTop maintenance
> > we can inspect modules for signs of degradation
(color changes, fogged glazing, de-lamination,
warping, or water leaks), cracked glazing, and/or
bent frames)
> > we can check all roof-top connections
> > we can tighten all roof-top mounting hardware
(it can loosen up, thanks to the wind always
tugging back & forth, trying to lift those many
long flat panels; wind force on the roof is far
different than that at ground level)
> > we can inspect exposed wiring for rodent & other
damage (see left photo below)
 
> > we can check for rust, galvanic corrosion, and
electrolysis (see right photo above)
> > we can secure any wiring loose under the modules
> > we can clip any new interfering vegetation growth
> > we can inspect that the cable-ties are UV-resistant
and are weather-resistant.
> > we can verify that cables are not exceeding
acceptable bend-radius and that they have any
needed drip-loop prior to entry points.
> > we can inspect module-to-module ground connections
> > we can apply restorations or sealants
> > we can verify proper required air-flow clearance
between the modules and the roof
> > we can verify that there are sufficient support legs
('standoffs') under the panels and their racking
--the correct number for some areas is not enough
for windier areas; panels may exceed their
flex-limit without sufficient stiffening (support legs)
> > we can inspect the sealants applied around all
rooftop penetrations
> > we can clean away cooling-inhibiting dust and dirt
from the electrical combiner box and from the
DC-to-AC inverter(s)
Roof Danger Factor:
Height, power lines, heat, glass sheets--
not a place to send a maid,
a window-washer,
a student, or a handyman!
