Solar power systems are expected to perform for more than 25 years. As such it is important that the right solar system architecture is used to ensure unfailing reliability over such a long operating period.

• The fact that a grid tied solar power system is entirely solid state enables these systems to operate for such long periods with minimal maintenance requirements.
• The typical grid connected solar power system has three main components: inverter, solar panels and MPPT.
• As solar panels are made entirely of aluminium and silica, they can be installed externally on the roof with little concern and requirement for future maintenance.
• Inverters are the main electronic equipment and it is important that all electronic equipment is installed in a safe and temp ambient locations.
• It is imperative that whilst certain solar architectures may offer increase performance, the medium to longer term repair and maintenance consequences should also be taken into account.
