Solar Panel cleaning is good business - it pays for both you and your customer.
SOLAR ROCKER has been developed from DEEP-FRAME ROCKER - available now as 16.5" wide, and the 22" wide version is in production - scheduled for release end of September.
As the effectiveness of the SCRUB of choice is determined by the total surface area and force applied, 16.5" will be more aggressive than 22", however, 22" will cover half a standard solar panel width, thereby reducing the number of stroke actions from multiples of '3 x 16.5"' to multiples of '2 x 22"'. Applying force to solar panels is not the same as to windows as the panels are at an angle, and often you are cleaning from the ground.
SOLAR ROCKER uses a flowrate of 3/4 GPM (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 8 'BASE JETS' to the underside of the brush, so there is more dirty water to pull off in the downstroke.
Remember that PIVOT on the SOLAR ROCKER is able to be set at a negative angle, so if you are cleaning from the apex of the roof, invert the brush so your rinse is in the right place, if possible (different roof pitches may change the possibility of this).
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.
