Abstract
This paper discusses two main methodologies of sizing photovoltaic installations and provides a comparative analysis in terms of the accuracy and feasibility of these two methodlogies. One of these two methodoligies is a simplified approach requiring very little data and information an dis based on some assumptions. The other, the loss-of-load probability method is statistically based ; it ismuch more elaborate and requires complex set of data. Our study shows that for a moderate PV installation to provide basic electrical needs of a small to medium-size detached family house, the simplified method is well suited for such conditions.
