CleanInG InstRuCtIons

reC Peak energy 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.

Cleaning of the panel should be carried out in the early morning when the panels are cool to avoid thermal shock.

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 soft 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 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, repeat the cleaning 

process.  if stains require more effort to be removed, iso-propyl alcohol of a concentration less than 10%.  acid or alkali detergent may not be used

Use of high pressure hoses or cleaners is not permitted as these may damage the panel, laminate or cells.

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 

left to dry in the air or wiped dry with a chamois.  avoid putting 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.  Please recycle according to local guidelines and regulations.

in order to ensure durable and safe connections between panels and bos equipment, the following instructions must be followed in order 

to protect the electrical connections from the elements.  More detailed information is given in the guide to best Practice - Connections and 

Connectors which can be found via the reC website Download Center (www.recgroup.com/downloads).

ConneCtoRs

• 

Connectors must be securely joined to each other according to the manufacturer’s instructions.  reC explicitly excludes the cutting of cables 

and replacement of connectors.  if this causes an issue for a particular site, contact reC via www.recgroup.com for further advice

• 

The use of any chemicals or lubricants on the connectors or contacts must be carried out in line with the connector manufacturer’s 

instructions

pRoteCtInG tHe Cables

• 

To prevent stress on the junction box casing, ensure the cable exits the junction box in a straight line before any bend in the cable.

• 

The cables on reC Peak energy panels have a minimum bending radius of 30 mm to avoid damage to the insulation (fig. 9)

• 

ensure cables do not hang loose where they may be damaged through friction or stress, e.g., caused by wind or grazing animals

• 

shield connectors from falling or dropping water by locating them directly beneath a panel

• 

Cables must be firmly secured to the structure, without overtightening, as this can deform the cable insulation

fig. 11:  Minimum bend radius of 1.2 in (30 mm)

seCuRInG Cables anD ConneCtoRs

• 

when securing the connector, place it away from the mounting structure with sufficient air circulation all around.  This allows the connector to 

dry effectively and avoids the risk of damage or degradation of the connection

• 

good practice is to secure the cable either side of the connectors, ensuring no stress is exerted on the connector casing or cable entry

To enable correct cooling and drying of the connectors, do not add extra protection to the connector, e.g., heat shrink, grease or tape
