Photovoltaic project analysis

A cash flow calculator for PV projects
PVcalcMore than a dozen variables can be entered to calculate the effective return of a photovoltaic ('PV') project, e.g. fixed cost, running cost (lease, insurance), financing cost. You can select whether to finance with an annuity, or a simple loan where you build up reserves as you go. There is a tutorial.
PV installation price forecast
PVcalcPanel price data from 2009 to 2012 is used to estimate the panel price evolution. If the trend continues, one can expect panel prices to halve roughly every 4 years.
