Q&A What does off-grid and on-grid mean ? Off-grid systems operate independently with battery storage for complete energy freedom, while on-grid systems connect to the utility, allowing you to save with net metering while keeping the grid as a reliable backup.   Why is my solar panel under producing ? Solar panel may be underproducing due to temporary factors like shading or weather, or due to issues like dirt, poor angle,regular cleaning and system checks can typically restore performance.   How should I connect solar panels in my electrical circuit (series vs parallel)? Choose series wiring to increase voltage for your inverter's needs, or parallel wiring to minimize losses from shading, but always match your final configuration to your inverter's specific voltage and current input requirements.   What is the meaning of 12V in the product title?Why is this value different from the voltage of the solar panel? When you open the product page, you will see a title like "xxx Watt 12V Solar Panel".The "18V" in the product title indicates that this solar panel is suited for a 18-volt system. Its actual operating voltage (VMP) is higher,which is necessary for efficient charging.
