It would be a good idea to buy your panels in even numbers, making it convenient to wire pairs in series if you want to change, say, from a 12 volt to a 24 volt system. To connect the components of a Solar Energy System, you will need to use correct wire sizes to ensure low loss of energy and to prevent overheating and possible damage or even fire. Table given below show wire Size (Top Row), Current in Amperes (First Column) and Max length of cable (Values inside the Table):-
