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.

MOUNTING OPTIONS

OPTION A. Attaching Mounting Bracket to Window Frame

OPTION B. Attaching Solar Panel via Velcro Strip to a Window or surface

INSTALLATION

Solar panel should not be too far from the window

because the performance will be reduced.

The back of the bracket should not be facing

opposite to the window.

Keep the solar panel as close to the window as

possible.

The back of the bracket should be facing toward

the window.

In case of an eave, shade or awning, the bracket

should not be bent.

Use velcro strips to stick the bracket on the

window (horizontal orientation).

Use velcro strips to stick the bracket on the

window (vertical orientation).

HORIZONTAL ORIENTATION VERTICAL ORIENTATION

INSTALLATION PROCESS

Fully charge the Motor or Battery Pack before beginning Solar Panel installation.

IMPORTANT

Ensure solar panel has adequate exposure to sunlight. When selecting a position for solar panel, consider any external

obstructions like trees, building, signs, etc. that may limit the amount of sun light reaching onto the solar panel.

IMPORTANT

The PV panel supports two motor voltages; however a single PV panel can only charge one motor type at a time. That

is, if the 12V port is connected to a 12V motor, the USB (5V) port is switched off. Conversely If the 12V port is NOT

connected, the USB port is automatically switched on.

IMPORTANT

OPTION A. Attaching Mounting Bracket to Window Frame

Locate the optimal position for solar panel in window.

Ensure all components are available for installation scenario.

Possible Orientations

Top Fix Side Fix

StickersScrew

i. Break off excess bracket length using Pliers (if required).

ii. Install mounting bracket to wall/mounting point.

iii. Fix Solar panel to mounting bracket using screw.

iv. Apply stickers onto the Solar Panel to seal unused mounting holes.

OPTION B. Attaching Solar Panel via Velcro Strip to a Window or surface

Stickers

Protective Film

Dual Lock

i. Clean solar panel front surface with alcohol wipe. Allow surface to dry.

ii. Peel protective ﬁlm off one side of Dual Lock and attach to one end of solar panel. Press adhesive tape ﬁrmly onto solar

panel surface for 5 seconds to ensure good adhesion. Ensure that Dual Lock does NOT cover any portion of the solar

panel cells. Repeat previous steps for attaching adhesive tape to other end of solar panel.

iii. Apply stickers onto the solar panel to seal unused mounting holes.

iv. Clean the window or surface with alcohol wipe. Allow surface to dry.

Peel protective ﬁlm off Dual Locks. Press ﬁrmly onto ﬁxing surface.

Apply hand pressure for 5 seconds and check if ﬁrmly attached.

Any partial or total covering of any solar panel cell will degrade solar panel performance.

IMPORTANT

BENDING BRACKET

Bend the bracket prior to installation of the solar panel.

IMPORTANT

Ensure the bend angle is between 150° to 180°.

IMPORTANT

Make sure that the solar panel has adequate exposure to sunlight.

IMPORTANT

Bracket can be bent in order to receive more direct sunlight which provides more energy to the motor.

The bracket should be bent at a distance of 22 mm, 36 mm or 48 mm from the base of the bracket as shown below:

CONNECTING SOLAR PANEL WITH MOTOR

Ensure any cables are kept clear of fabric at all times.

Connect solar panel with the motor.
