Costing in Solar Photovoltaics
Capital expenditure
The use of capital in solar pv projects differs from project to project, especially costs for development and any infrastructure such as interconnection, overhead lines or civil engineering works. The most weighty cost items however remain modules, inverters and installation.
Operational expenditure
Operational expenditure in solar is very small, particularly since there are no moving parts and solar panels will only be replaced if they are damaged.
