SOLAIRE BY SUNPOWER SOLAR CARPORT STRUCTURES
Canopy Maintenance Guidelines 2016 (R1.5)
In order to maintain the appearance and proper function of Solaire By SunPower solar carport structures, Solaire recommends
following these general maintenance guidelines at least (2) times per year for inland locations, (3) times per year in coastal
regions. Please note that these guidelines illustrate maintenance guidelines for only the support structure and related
components. Maintenance requirements for the solar and/or electrical components of the system are provided by others.
1.
CONCRETE PIER INSPECTION
a.
Visually inspect exposed portions of the concrete pier for vehicle damage.
i. Pier vehicle damage exceeding 1.5" of depth and/or significant enough to expose reinforcing bar should
be patched and parged immediately to prevent corrosion of reinforcing steel.
2.
BOLT INSPECTION
a.
Baseplate Connection. Visually inspect exposed baseplate bolts to confirm that all nuts and bolts are present
and that no visible gaps appear between the bolt and the structural member.
b.
Structural Steel Connections. Visually inspect exposed bolts at the column/crossbeam to confirm that all nuts
are present and that no visible gaps appear between the bolt and the structural member.
3.
STRUCTURAL STEEL FINISH INSPECTION
a.
Visually inspect painted and/or galvanized finishes at exposed structural steel
i. Vehicle and or equipment damage that exposes bare metal must be touched up immediately in order to
limit corrosion. Any other areas of bare metal must be touched up immediately.
4.
DRAINAGE INSPECTION (Water Management projects only)
a.
During rain or snow melt conditions, visually inspect drain outlets to confirm water is flowing out consistent with
outflow at all other drain outlets.
i. If flow is diminished at any location, gutter and/or downspout may require cleaning.
ii. Downspout pipes may be cleaned from below with a plumber's snake or similar tool.
iii. If required, upper portions of the downspout and cleanout fittings are directly accessible by removing
the gutter cover located below the gutter at each column. The downspout on the uphill side of the
column typically receives most water flow and should be cleaned first.
iv. If required, clean the gutter and drain assembly directly from above. Follow PV panel manufacturer
guidelines when walking on or around the PV panels.
v. During winter conditions, any accumulation of snow or ice at the drain outlet must be cleared in order to
maintain drain flow and prevent downspout pipe freezing.
5.
LIGHT GAUGE METAL PANEL INSPECTION (Water Management projects only)
a.
Visually inspect metal gutter, decking and fascia panels to confirm that panels align and seams are generally
tight.
b.
Visually inspect metal panel components for vehicle or equipment damage.
i. Vehicle and or equipment damage that exposes bare metal should be touched up in order to limit
corrosion. Any other areas of bare metal must be touched up immediately.
6.
LIGHT FIXTURE INSPECTION
a.
Visually inspect light fixture to confirm that fixture is operating and that fixture aiming is consistent with adjacent
fixtures.
b.
Relamp fixtures as required according to manufacturer recommendations.
7.
CLEANING
a.
Cleaning requirements will vary based on local conditions and individual owner maintenance programs. Solaire
generally recommends a cleaning interval of 18 - 24 months.
i. Consult PV panel manufacturer and installer prior to start of work for cleaning and maintenance
guidelines on and around PV panels and related equipment.
ii. Consult light fixture manufacturer prior to start of work for cleaning and maintenance guidelines for light
fixtures.
iii. Clean exposed areas of the canopy using water and mild soap.
iv. Use of pressure washers for cleaning is discouraged. Excess water pressure can damage canopy
finishes and components.
