ANNEX . INSTALLATIONS ON WATER PLATFORMS
REC TwinPeak panels have not been certified for installation on water platform-type mounting systems. When installing REC TwinPeak panels
on fixed position (e.g., anchored) water platforms, for example, floating pontoons, follow the instructions below specific to such applications.
Failure to do so will invalidate the warranty.
For all installations on water platforms, first advise REC before the start of installation in case of any site specific instructions or
constraints
INSTALLATION ENVIRONMENT
i) Installation site
• REC panels may only be installed on closed bodies of fresh water where water salinity does not exceed mS/cm at °C ( PSU). This
specifically excludes mounting on sea and ocean applications.
• The maximum permied wave height must not exceed m from the crest to the trough of the wave.
ii) Floating platforms
• When using a floating platform, follow the manufacturer’s instructions regarding installation, maintenance, inspection and cleaning at all times.
iii) Minimum installation height
• The minimum installation height of REC TwinPeak panels on floating platform systems is cm and is defined as the height between the
water surface and the lowest edge/part of the panel during normal operation. This will help to shield the panel from direct water spray.
INSTALLATION INSTRUCTION
i) System installation
• All cables used for the installation must have sufficient length and slack to prevent damage due to water level changes and wave motions.
Negative system grounding is required for REC TwinPeak panels installed on a floating platform
ii) Mounting panels
• Installation of REC TwinPeak panels must be in accordance with the aforementioned standard mounting instructions.
• The junction box should be oriented as far as possible from the water surface according to system design and the junction box, cables
and connectors must be protected from direct water splash.
• The installation must allow for sufficient spacing between individual panels, in order to avoid all contact as caused by the natural
movement and flexing of the floating structure.
iii) Panel protection
• In areas with high avian activity, additional bird repelling devices may be installed as long as they do not adversely affect system
performance.
• If using lightning protection equipment on the floating installation, all relevant local regulations must be respected.
MAINTENANCE
• Regularly inspect the installation to ensure all panels are securely mounted.
For installations with high avian activity, system cleaning may be required at more frequent intervals to reduce shading of panels
caused by bird defecation
SAFETY
• Immediately disconnect the system if the installation or the floating platform exhibits deviation from standard operating conditions.
• In the event of the floating platform being submerged, disconnect the DC connection at the inverter immediately. Do not aempt to
salvage panels when sunlight is present.
