Solar is a great alternative.
The 180W solar panel comes with a built-in controller and is ready to charge a battery or to use it as a solar generator.
Zamp Solar in the U.S. manufactures the Monocrystalline
portable solar module. It exists of two 90 watt solar panels. This is a
suitcase kit with an own handle to carry, it is portable, a breeze to set up and
easy to transport.
The 180W solar panel kit contains 2 x 90 Watt solar
modules and removable MC4 connector cables.
It also comes with alligator clamps, cables, as well as a
10 Ampere charge controller.
One can use these solar panels for many years. You will
experience no faults, defects or operating failures.
It comes with a superb warranty for up to 25 years.
On a sunny day with 7 hours of sunlight in mid-summer,
you can bargain for the generation of about 1.2 Kilowatt.
That is 7 x 180 watt = 1,26KiloWatt.
Now you allow for a loss of 15% and you get 1, 26 X
85/100 = 1,071 Kilowatt
Ignore the 0,071 and you get a fair 1 Kilowatt.
Maximum Power: 180Watt.
Open-Circuit Voltage (Voc): 21.6V
Optimum Operating Voltage (Vmp): 17.8V
Optimum Operating Current (Imp): 4.5A
Short-Circuit Current (Isc): 4.95A
Weight: 34.35 lbs.
Open; 40” x 39.5“x 1.5” inches
Folded; 20” x 39.5“x 3" inches.
The 180Wsolar panel comes with a 25-Year Output Warranty.
The 180W solar module is multi-functional. It runs interior lights, charge laptops and handheld devices. It also runs fridges and fans.
It works for RVs, trucks, campers, and boats.
This solar panel module comes with an integrated 5 Stage 15 Amp solar charge controller.
This is a PWM charge controller.
The mounting of the controller is on an EZ-View bracket.
You can take the bracket swing it out and take the reading. When you let go the
controller will swing back into position.
It can plug into a solar panel port on a camper if
provided. It can also connect directly to the battery terminals by making use
of the alligator clips.
The solar charge controller protects the battery from
overcharging. It turns on and off depending on the status of the battery.
It will also ensure safe operation during surges and
It has a digital display and LED indicator. The lights provide
charging information w.r.t. the battery.
Use the controller when charging 12V batteries.
Set up takes less than 5 minutes.
You take the 180w solar panel out of the box. Then you
unzip the bag. Now you unfold the panel.
Then it is a matter of adjusting the tilt legs and directing the module to the sun. Connect the wire to batteries, and you are receiving free energy from the sun.
To make the 180w solar panel fully operational we need a charge controller and battery.
Also an inverter if we want to run ac appliances.
Size the battery by dividing the total watt by volts.
This is 180 watt x 6 hours sunlight( Depending on the area you live.) X .85 for losses/ 12 volt x 2 for DOD(Depth of discharge.)
This is 180 x 6 x .85 / 12 x 2 = 153 Amp Hours .
A 160 Ah battery will be a good choice.
Size the inverter by deciding the max watts to be utilized at once.
The max output of the panel is 125 watt.
Rule of thumb is to use an inverter 1.25 to 1.5 times more than max watts.
In this case we can work with 180 X 1.5 = 270 watt. A 300 watt inverter will be a good choice.
Each solar kit includes a 16-foot wire with detachable alligator clamps on the end.
You can connect the solar kit to the battery with the alligator clips.
Many RV's come prewired for solar with an integrated solar port. If this is the case you detach the alligator clips. It reveals a plug that fits into the integrated solar port. Now you can connect without using the alligator clips.
The only maintenance that you as a user have to do is making sure the cables are not damaged. This is to ensure a good working condition.
Cleaning the surface of the a solar panel is also very important. Use a damp cloth to perform this duty.
If necessary you can buy a proper solar cleaning liquid.
You can also buy a a convenient solar brush for cleaning the surface of the panel.
A dirty panel leads to a big drop in efficiency.
A professional person must perform all other maintenance functions.
This 180W solar panel is light; it is easy to carry and to set
it up. It delivers high output and the built-in charge controller makes life
The crocodile clips and MC4 connectors come in handy.
The package has a neat and clean design and the panels
are well built and sturdy.
To be honest it is a pleasure to buy this product. It is
appalling and one cannot wait for the opportunity to put it into operation.
The 180W solar panel is affordable. The price is very reasonable and you buy a system with high efficiency.
It delivers a more than satisfactory output.
