Solar Panels
MiniScience offers expandable
solar panel modules that can work independently or can be linked to each other
to produce higher voltage or higher current or both.
Each solar panel module is coated with
Polycrystalline Epoxy Resin for added protection.
Small Solar Panels (1.5 V)
This is the smallest solar panel that can
individually run a small hobby motor Such as RE140RA, RE140SA or any of the
RF300CA motors. Only one of this solar panel is used in Solar Car Kit of
MiniScience and it is sufficient to run the card in a smooth flat surface. Some
students install 2 of this solar panels in their solar car models to generate a
higher torque. Give one solar panel, one motor and one propeller to each student
and allow them to discover the solar energy for themselves. They will soon learn
that the angle of sunlight is an important factor in the amount of electricity
produced by solar panels.

Large Solar
Panels (6 V)
This is the perfect solar panel
for learning or teaching about solar energy. It produces enough electricity to
run almost every hobby motor, every light bulb, and operate every electronic
device rated up to 6 volts. (See the list below).

The DC motors you can try with
this solar panel include:
-
RE140RA (For demonstration and short term operations)
-
RE140SA (For demonstration and short term operations)
-
RC280SA (For demonstration or long term operations)
-
RF300CA11400 (0.7 V - 5.0 V)
-
RF300CA14270 (0.5 V - 4.0 V)
All the above motors are also compatible with our
propellers.
All MiniScience LED's and small light bulbs can also operate with this solar
panel. Please note that if the voltage of solar panel is much higher than the
rated voltage of light bulbs, it can burn the light bulb.
The electricity produced by each
solar panel comes out of the back using a pair of (red and black) wires. Output
wires are soldered for added security and have insulated and tinned ends for
easy connection.
Solar panel modules are used for
solar energy science experiments, solar cars, solar robots and solar chargers.
Optimize your solar panel
For best performance solar panel
modules must be under direct sunlight so that the sun rays hit the surface of
solar panel in a right angle. The produced voltage will be lower if the weather
is cloudy or sun rays reach the panel on a sharp angle.
Produce more voltage
You may connect 2 or more solar
modules in series in order to produce more voltage. To connect in series you may
connect the red wire of each module to the black wire of the next module. The
voltage between the black wire of the first module and the red wire of the last
modules is usually calculated by multiplying the voltage of one module by the
number of modules. For example you may connect 4 of the 1.5-Volt solar modules
in series to produce 6 volts.
Produce more current
You may connect two or more solar
modules in parallel in order to increase the current. For parallel connection
you will connect all red wires together and all black wires together. The
maximum output current of parallel solar modules may be calculated by
multiplying the max current of one module by the number of modules.
Produce more voltage and
current
Solar modules may be connected
both in parallel and in series to produce more current and voltage. For
example you can make an array of 60 solar modules in 10 rows (6 panel in each
row). Panels of each row are connected in series, while the rows are also
connected to each other on their ends to form a parallel connection.
Store the produced energy
Solar panels do not store energy.
The production of electricity stops as soon as you remove the solar panel away
from the sunlight. Electrical energy from solar panel can be stored in batteries
for later use. In order to store electricity from solar panel you will need a
battery or an array of linked chargeable batteries with sufficient capacity for
the amount of energy you want to store and the amount of energy your solar
panels produce. You will also need a charge controller that can regulate the
charge process and connect or disconnect the circuits as needed.
