I am sorry to say that your stand-alone simulations are very poor. At "the time of truth" (i m involved in the energization of an island), PVSYST is completely failing:
1) Hourly results are inconsistent. Whereas the report says, e.g. that my system covers 45% (55% generator) when I make excel tables with hourly results, it seems that hourly energy load is equal to energy for the user --> hour by the hour along the whole year my system covers 100%
2) When I set a generator, magically, the smaller I choose it, the better my system fulfills the loads along the year.
3) Sometimes, when I add more batteries, the results are better, or said in other words, sometimes I reduce, for ex. a subsystem of 168 batteries (48 V system with 24 x 7) to only three parallels. The result is almost the same...should we save battery investment now or again there is an inconsistency??
The fact is that I un capable of designing the microgrid of this island. There are lots of money and prestige in this "game," and I cannot rely on PVSYST.
CAN YOUR TEAM SOLVE SOMETHING OF THIS? Please, Andre, I wish you could work it out...maybe in new releases. Escape Promo Code
