Off-grid Sunmodule™ solar panels

Not all off-grid modules are created equal. We have designed and manufactured these modules for optimal performance in off-grid applications. Since 12 V batteries are commonly used in off-grid systems we have designed our Sunmodule solar panels to optimize charging these batteries. When using batteries with higher voltages such as 24 V or 48 V, 2 or 4 Sunmodule solar panels can be connected in series to generate the optimum battery charging voltage. Higher power systems can be achieved by connecting strings in parallel to reach the required number of modules. If using a maximum power point tracking (MPPT) charge controller, you can use any of SolarWorld’s Sunmodule solar panels in your off-grid project.

Small scale off-grid solar panels Small off-grid homes
Small homes in remote locations can now be equipped with some modern conveniences. A small-scale off-grid solar system can provide a reliable and continuous energy supply that can be more economical than a grid connection if it is available. The example below shows a system using a Sunmodule SW 50 solar panel, a charge controller and a battery. Thousands of these types of systems have been installed around the world and provide critical power for safety, lighting and communications.

Off-grid solar powered homesTelecommunications
Telecommunication companies often run into challenges when trying to provide coverage to remote and rural locations where no grid is available to connect to for powering their transmitters. With a medium to large-scale off-grid system, telecom providers can deliver reliable, continuous service to any remote area. These systems can be designed to operate completely off-grid or as a reliable hybrid system tied to the grid as shown below. SolarWorld has been supplying reliable off-grid solar systems to telecom providers for 35 years.

Solar power for the entire community Power for the entire community
The sun shines brightly on many rural communities, however, they can’t get access to electricity because there is no grid nearby. Those communities can turn that sunlight into electricity by using a central off-grid system to provide power that can be shared by everyone. This example shows the Sunmodule SW 135 solar panels supplying energy to a small village.

Diagram of off-grid water pumping with solar power Remote applications
Access to clean drinking water and lighting are two of the greatest challenges for many remote villages and towns. Solar power systems can provide this access by using solar-powered water pumps and purification systems. These off-grid systems are simple to design and install and often do not require batteries for electrical storage. As seen in the diagram below, the amount of water needed on a daily basis is pumped into a tank during daylight hours where it is stored until consumed. A small system can also be used to power street lights by adding a small battery and charge controller to provide light and safety for travelers on remote roads.
