How much does PV power cost?
To buy a photovoltaic panel in small consumer quantities presently costs about $5/Watt. This number can vary widely depending on the amount of photovoltaic panels bought. Furthermore, installation and other component costs can up to double this number. An estimate for the installed price of a residential system is about $7/Watt, for a remote system up to $10/Watt. Although less common, a PV panel may also be priced in $/m. When priced in this way, it is difficult to compare to other panels priced in $/Watt, since the conversion factors depend on the panel efficiency, which is usually not given. It can however, be possibly determined by the power produced and the module area.
