Actually you have to use SAP 2005 not SAP 2009 and you can't use it as a replacement but you can provide the customer with it as long as you make no claim that it is better than SAP 2005. If you're not using PPVSOL how are you doing your roof layout to show your customer and how are you working out which panel and inverter combination is best for the roof? It's cut down the time I spent on attempting cad drawings which I was rubbish at and in the blink of an eye once the roof parameters are in I can try all sorts of different panels, layouts, look at shading .... that's what takes the time but it's what customers appreciate too.
