Hi Andre, The economic evaluation here in the UK is becoming ever more important. It is so important to be able to predict the energy savings and be able to present data to clients in a simple way. Have you used PV Sol for example? The economic evaluation in there is excellent. What improvements do you intend to make? Personally I would like to be able to consider the Feed In Tariff, the Export tariff, the customers current price per KWh, inflation on the feed in and export tariff and be able to show how much the client would be saving in year 15 assuming an annual 4% inflation rate on their energy bills. I am not sure if you are aware but in the UK we have "deemed" billing for the export tariff. This means that the energy supplier automatically assumes that you are exporting 50% of your generation. So this means that if you managed to use 100% of your energy generation you would still be paid the same amount of money. Basically it means that the export tariff is paid on top of the generation tariff for 50% of your generation. For systems over 30KW energy suppliers fit import/export meters and pay you on the recorded units you export. I love your software but the economic side really lets it down at present. I intend to have a further look at the weekend and see exactly what can be done presently.
