MAINTENANCE
CLEANING INSTRUCTIONS
REC TwinPeak solar panels have been designed for easy maintenance. Normal rainfall will naturally clean the panels if installed at a sufficient
angle. The need for cleaning will vary dependent on location, rainfall, pollution and angle of installation – the lower the angle of installation, the
more cleaning will be required. To optimize electrical output it is recommended to clean the panels when dirt can be seen on the glass surface.
If dirt remains on the panel, it may cause cell shading which will reduce power output or even cause further damage. To clean either the front
or rear of the panels, use only deionized water at ambient temperature and a sponge, microfiber cloth or a so brush to wipe away the dirt
(rainwater, tap water or diluted alcohol may also be used as a secondary solution). For further cleaning a mild, biological and biodegradable
washing-up liquid may be used.
When cleaning the panel, take care not to scratch the surface or introduce foreign elements that may cause damage. Ensure the water used
is free from grit and physical contaminants that may damage the panel. Always rinse the panel with plenty of water. If soiling remains on the
panel, repeat the cleaning process. If stains require more effort to be removed, Isopropyl alcohol of a concentration less than may be
used. Acid or Alkali detergent may not be used.
Use of high pressure hoses or cleaners is not permied as these may damage the panel, laminate or cells.
Cleaning of the panels should be carried out in the early morning when the panels are cool to avoid thermal shock.
Using a rubber squeegee, wipe the panel surface from the top downwards motion to remove any residual water from the panel glass. Panels
can be le to dry in the air or wiped dry with a chamois. Avoid puing pressure on the panel surface when drying.

SYSTEM INSPECTION
The system should be inspected regularly to ensure that:
• Fasteners are secure, tight and free from corrosion.
• Electrical connections are secure, tight, clean, and free of corrosion.
• The mechanical integrity of the cables is intact.
• Bonding points to ground are tight, secure and free from corrosion (which could break the continuity between the panels and ground).
RECYCLING
REC has made every effort to ensure panel packaging is kept to a minimum. The paper and cardboard packaging can be recycled and the
protective wrapping and panel separating blocks are also recyclable in many areas. Recycle according to local guidelines and regulations.
