Solar Panel Battery Charger
RTMSOLAR2
When paired with our solar panel, Li-ion motors or battery packs remain powered by harnessing
the natural energy of the sun. Sleek design allows for unobtrusive placement behind most headrails.
The charger uses industry leading, crystal technology to maximize sun ray absorption in a wide range of locations and
orientations. Renewable power means motors stay running for longer, without the need for regular charging.
Solar Panel Battery Charger - Use the sun to your
advantage with our R-TEC Automation®Solar Panel,
even when Solar Panel is partially shaded.

LIGHT TRANSMISSION
Light transmission can vary widely with the number of window panes and types of coatings. The type of glass needs to be
assessed. Approximate transmission factors are:
Glass Type Transmission Factors
Single Panel 70%
Double Panel 63%
Double Panel with bronze tint 30%
Double Panel with selective low-e coating 45% - 57%

ASSESSING THE INSTALLATION LOCATION
PRE INSTALLATION ASSESSMENT
Hold the Lux meter directly against the window glass indoors in the location you wish to mount the solar panel, and observe
the KLux Reading.
Lux Meter
Measuring sunlight through the window

Using the time of the day that the measurement was taken, select the coefficient that corresponds to your region / time of year.
Use the value calculated from the table above with the graph below to estimate the number of cycles that the solar panel can
provide over a 24 hour period.
Note: 0.00 coefficient means that the sunlight intensity is too low to be measured accurately.

EXAMPLE OF PRE INSTALLATION ASSESSMENT
Measure the KLux using a Lux meter
Measured Value = 20KLux
Measuring sunlight through the window
Measuring sunlight intensity at 3:00 PM during winter of Northern Hemisphere, for a M25 motor installation:
Multiply the measured Value by the coefficient in the table on page 9.
Sunlight intensity = Measured Value x coefficient
Sunlight intensity = 20KLux x 1.51 = 30.2KLux
Estimate performance
Calculated sunlight intensity = 30.2KLux
Locate 30.2KLux on the x-axis and draw a vertical line from it until it meets the motor curve.
Draw a horizontal line intersecting the vertical line and the y-axis; gives an estimated number of cycles (within a 24-hour
period) that can be achieved without depleting the battery level. i.e. the motor is only consuming energy harvested from
the sun.
In this case it is approximately 10 cycles.
