SOLAR ROCKER has been developed from DEEP-FRAME ROCKER - available now as 16.5" wide (22" wide on demand).

Most Solar Panel Cleaners do not understand ARC (Anti-Reflective Coating) on some solar panels - you can recognize it by the 'matt' surface - it is not as reflective as plain glass.  ARC is a nano-coating that increases the solar gain of a clean solar panel by 4%.  ARC be easily damaged by overly aggressive brushes or SCRUBS. This is the reason we released the SILICON SCRUB for SOLAR ROCKER - this is a soft SCRUB that has a high friction co-efficient to 'grab' dirt off the solar panels, and it is self-cleaning, so it will not drag debris across the panel surface. Of course, not all debris can be removed with SILICON SCRUB, so we include other, more aggressive SCRUBS in the kit.  Even we want to protect the ARC, the problem is that a dirty solar panel can reduce solar gain by 20-80%, so it is, in fact, more valuable to the building owner to have clean panels, even at the risk of slightly damaging the ARC. 

SOLAR ROCKER uses a flowrate of 3 LPM as there is always a lot of dirt to pull off the glass, and as the angle of the panel is not vertical, the water does not flow as fast. To help get the dirty water off the panel, we have added 4 'BASE JETS' to the each side of the underside of the brush, so there is more water to pull off excessive dirt in the downstroke.

Remember that PIVOT on the SOLAR ROCKER is able to be set at a negative angle, and with our HDG ADAPTOR (included) you can be cleaning panels from the apex of the roof, with your rinse bar on the 'high side'.

The key to efficiency is always in reducing the length of distance your brush travels and the amount of force required to effect the change.  This is why it is really important to get the agitation and rinse right, and match it to the brush size.  There is no point doing 10 strokes with a 12" bristle brush that needs four overlaps to get from one side of the panel to the other, when you could do three sets of 2-3 strokes with a 16.5" SOLAR ROCKER, or two sets of 2-3 strokes with a 22" SOLAR ROCKER.  

Remember we need FLOWRATE to make rinse efficient - that is why we designed SOLAR ROCKER to use RADIAL HI-FLO tube  - it is 3/8" OD (10mm).  Usually, we recommend anything longer than 75FT should be 1/2" or 5/8" (12-16mm) hose, however, if you have great pressure, you can use up to 150FT of RADIAL HI-FLO.
