Solar Array Installation Process

Although the actual installation may only take two or three weeks, the whole process can take many months.  Planning permission can take upward of 6 months if required, applications to the local Distribution Network Operator (DNO) to patch into the national grid can take 6 weeks. Add to that site surveys, designing,  structural surveys, energy performance certification, delivery, scaffolding and all of the essential registration procedures, as well as adverse weather conditions, then the entire solar installation could run to over 6 months.
