PANEL MAINTENANCE
CLEANING INSTRUCTIONS
REC solar panels have been designed for easy maintenance. However cleaning solar panels can assist in optimizing electricity output. The need for
cleaning will vary dependent on location, rainfall, pollution levels and the angle of installation – the lower the angle of installation, the more cleaning will
be required. ‘Normal’ rainfall will naturally clean the panels if installed at a sufficient angle to ensure water runs off the surface. To optimize electrical
output it is recommended to clean the panels when dirt can clearly be seen on the glass surface.
Using a so rubber squeegee, wipe the panel surface from the top downwards to remove any residual water from the panel glass. Take care not to
scratch the surface or introduce foreign elements that may cause damage to the panel. Always rinse the panel with plenty of water. Panels can be le to
dry in the air or wiped dry with a clean and so cloth or chamois.
For more information on cleaning REC solar panels, consult the
REC Cleaning Information Sheet
which is available to download from the online REC
Download Center www.recgroup.com/downloads. If in doubt at any time when cleaning the panels, stop and obtain professional advice.
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 makes 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 packaging and panels according to local guidelines and regulations.
DISPOSAL OF OLD ELECTRICAL AND ELECTRONIC EQUIPMENT
Panels should be recycled at the end of their useful life according to local guidelines and regulations. By ensuring REC solar panels are disposed of
correctly, you will help prevent potential negative consequences for the environment and human health which could otherwise be caused by inappropriate
waste treatment. The majority of the panel components can be recycled.
NOTE
• Avoid puing pressure on the on the panel surface when cleaning or drying, e.g., leaning, standing or resting buckets on it.
• Use only deionized water free from grit and physical contaminants, at ambient temperature and use 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.
• If stains require more effort to be removed, Isopropyl alcohol of a concentration less than may be used. Acidic or alkaline detergent may not
be used.
i
CAUTION
• Panel cleaning must always be carried out when the panels are cool, e.g., early morning, to avoid breakage through thermal shock.
• Use of high pressure hoses or cleaners is not permied as these may damage the panels, laminate or cells.
