Combining several solar panels creates an array, which is part of your solar system. The size of your solar array depends on where you live, the position of your roof and the energy needs of your family.
Solar Array in details:
A Solar array starts with solar cells or photovoltaic cells – which are then grouped together to make solar panels. This group of solar panels is called any array. Your solar consultant may use this term when he or she discusses your energy needs and how many solar panels (the size of your array) you need to power your home.
