NOTE 1 For an off-grid stand-alone PV system, the costs associated with storage battery maintenance and replacement are excluded from the turnkey price.

NOTE 2 If additional costs are incurred for reasons not directly related to the system, these are excluded (e.g., if extra costs are incurred fitting PV modules to a factory roof because special precautions are required to avoid disrupting production, these extra costs are not included. Equally, the additional transport costs of installing a telecommunication system in a remote area are not included).
