Solar photovoltaic (PV) modules are solar panels that generate energy and not just heat water. When these panels are exposed to light, they create electricity. Solar PV panels do not require electricity to operate. Solar PV refers to the solar panels that are installed on the roofs of homes and businesses. Solar PV panels can also be placed on the ground and wired into your home. You may also add battery storage so that you can collect electricity throughout the day, store it, and utilize it afterwards. A hot water diverter may be placed as part of the system to convert extra energy into hot water. This is ideal for when the weather is warm as you won’t want to turn on the heat or immersion.
