The 125 watt solar panel is from Value Line Solar. These are high quality industrial and rugged solar modules.
Use it to power or recharge about anything from your home, cell phone or any other appliance.
It comes with 36 solar cells connected in series. This ensures max battery charging performance.
call it the VLS-125W, 125 Watt 12V Solar Panel with junction box. This is a
conduit ready junction box.
Manufacturing takes place under ISO 9001 certified conditions. In other words the manufacturer pays extra attention to the customer.
polycrystalline solar panel comes with a heavy duty anodized aluminum frame.
The modules can withstand harsh weather conditions. High winds, heavy snow
loads and extreme temperatures.
They encapsulate the cells in EVA.
EVA (ethyl vinyl acetate) is available in thin sheets. The manufacturers insert these thin sheets between the solar cells. Also between the module and the top surface. They also use it between the module and the back surface.
Open-Circuit Voltage (Voc):
Short-Circuit Current (Isc):
Use these 125 watt solar panels for domestic and commercial stand-alone applications;
You can use it for remote industrial off grid solar systems.
Microwave/radio repeater stations.
Traffic message board OEM.
It provides electricity for villages in remote areas.
Use it for RV’s and for camping in remote areas.
Use it for medical facilities in rural areas.
Wi-Fi & WiMax.
As a power source for summer vacation homes.
LED outdoor lighting.
Water quality and environmental data monitoring systems.
Emergency communication systems and many more.
59.2 x 26.5 x 1.97 inches.
To make the 125 watt solar module fully operational we need a charge controller, battery and an inverter.
Size the charge controller by dividing max watts per hour by total volts.
This is 125/12 = 10.4 Ampere
Add 25% for safety and you get a 13 Ampere charge controller.
A 20 Amp charge controller will be a good choice.
Size the battery by dividing the total watt by volts.
This is 125 watt x 6 hours sunlight X .85 for losses/ 12 volt x 2 for DOD.
This is 125 x 6 x .85 / 12 x 2 = 106 Amp Hours .
A 110 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 a 250 watt inverter which makes the system much more flexible.
The solar module comes with clear information. You do not have to go and look for the data, it is right there and available.
The 125 watt solar panel is a handy and very usable piece of solar equipment.
Value Line Solar is a good manufacturer and the solar modules are of high quality. The modules last for many years to come.
