All components used in off-grid PV systems generate heat when operating because they are not 100% efficient. The rated output or performance for a given component will always be measured at a specific temperature and temperatures in excess of that value will lead to reduced performance (lead acid batteries will temporarily have improved performance, but their cycle life will be shortened in compensation). This means that cooling, especially in warm climates, is very important and must be carefully considered to ensure that a system performs properly. If a particular component has clearance requirements they will be outlined in the manual or installation guide. Inverters and charge controllers will have specific required clearances, PV modules often do not give guidance, but there are guidelines available in the mounting systems page.
