MAINTENANCE
CLEANING INSTRUCTIONS
REC solar panels have been designed for easy maintenance. The need for cleaning the solar panels will vary dependent on location, rainfall, air 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 optimize electrical output it is recommended to clean the panels when dirt can be seen on the glass surface.
Panel cleaning should always be carried out when the panels are cool to avoid breakage through thermal shock, e.g., early morning.
The build up of dirt on the panel surface over time may cause cell shading which will reduce power output or can even cause further damage. To clean
either the front or rear of the panels, 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.
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 permied as these may damage the panels, laminate or cells.
Using a so rubber squeegee, wipe the panel surface from the top downwards to remove any residual water from the panel glass. Panels can be le to dry
in the air or wiped dry with a clean and so cloth or chamois. Avoid puing pressure on the on the panel surface when drying, e.g., leaning or standing on it.
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.
