Solarland modules over 100W are built with integrated output cables. The junction box in these modules is sealed for better resistance to any type of environment. In the back of the panel you will find two output cables with Multi-Contact Type IV (or MC4) connectors, one male and one female. The MC4 connectors allow for safe outdoor connections without the need of additional measures like enclosures, electrical tape or connection boxes. MC4 connectors provide a very easy mechanism to connect and disconnect the solar panels in installations that are not permanent where the panels need to be stored during some months of the year. Use the following link to learn more about the type of junction boxes featured in Solarland solar panels.
Recommendations for the Solarland 120W solar panel:
Small applications with solar panels larger than 10W require a charge controller to regulate the charging of the battery. 10A charge controllers are well suited to operate with solar panels ranging from 45W to 120W. Some of our most popular models are the Phocos CMLup10 and Phocos ECO 10. Both controllers feature Low Voltage Disconnect (LDV) and can operate interchangeably with 12V and 24V systems. If LVD is not needed, the CM 10 can be a good fit for a small system.
You can use the SLB-0114 bracket made by Solarland to mount solar panels ranging from 85W to 140W on a pole or wall. Mounting bracket SLB-0103 provides a way to tilt the solar panel and can be used with a singe panel on a wall or flat surface. Alternatively, the Universal Z-shape mounting brackets SLB-0102 can be used to mount any Solarland solar panel ranging from 10W to 140W on a flat surface.
Some handy accessories to control your load include the Flexcharge 12V Timer and the 12V Watchman Photoswitch.
To facilitate the selection process we have put together a series of complete kits that include, solar panel, charge controller, cables and mounting brackets. They are available in 12V and 24V. You can see them in the Complete Kits section.
SolarLand USA is a subsidiary of Solarland’s factory in Wuxi, China which was funded in 2003. Their USA office was stablished in Grayslake, Illinois in 2008 to better serve the American market. Their main distribution facility is located in Ontario, California. Solarland specializes in 12V and 24V solar panels for mobile, off-grid and remote applications. Their solar panels are assembled in China with non-Chinese PV cells. All their solar panels are built with high quality anodized aluminum frame and come with a 25 year standard warranty. In their Ontario warehouse, Solarland stocks large quantities of solar panels ranging from 3W to 160W to cover any of your low-power charging needs.

Each time you charge deep cycle batteries with solar panels, it's necessary to use a charge controller in the circuit to protect the battery from over charging, and in some instances from over discharging. The only exception is when using solar panels smaller than 5W. Choosing the most suitable charge controller is simple and only requires two steps:
Step 1 - Voltage selection
Select a charge controller that is compatible with the system voltage. The standard configurations are 12, 24, and 48 volts. If you are wiring your batteries for 24 volts you need a charge controller that is rated at 24 volts.
Some controllers are voltage specific, meaning that the voltage cannot be changed or substituted. Other more sophisticated controllers include a voltage auto-detect feature, which allows it to be used with different voltage settings.
Step 2 - Current capacity
Select a charge controller that can handle the maximum output current of the solar panel (or solar array). The maximum possible current that a PV panel can generate is the “short circuit current,” indicated as Isc in the panel’s label or specs sheet.
It’s recommended to include a safety factor for isolated events as well. For example, a solar panel with a Isc of 7.89 amp could potentially produce an extra 25% on a sunny day with very clear snow pack. (additional light reflected off the snow). This results in a possible maximum of 9.86 amp (7.89 x 1.25 = 9.86 amp). In this case, a 10 amp charge controller would be recommended.
Below you will find a quick guide to choosing the proper charge controller for several popular solar panel sizes.
