julmou Posted October 12, 2022 Share Posted October 12, 2022 Good day, I would like to expand on this topic (https://forum.pvsyst.com/topic/2715-economic-evaluation-tariffs/) from May 2022. See, I have been using the Sunny Design Web Tool for comparison purposes for a bit of time (https://sunnydesignweb.com/sdweb). I really like how we can edit the Tariff section there and, because I think PVsyst is lacking in that area, there is definitely inspiration to be taken there. See example below, for a Self-Consumption project. On the first screenshot, we can see there's already quite a few options and parameters that can be entered for both the purchased electricity from grid (purchasing tariff) and the sold electricity (feed-in tariff). But then, what really shines is the next part (2nd screenshot), where we can add "Special tariff" with different values depending on the season/months, on the day of the week, and on the time of the day. Adding two Special Tariffs: one that applies only from 1st Jan to 31st March, only on weekdays, and from 6am to 2pm. one that applies only in July, at any time of the day, but only on weekends I find this Special Tariff interface quite simple but very powerful. Hoping this would give some inspiration to improve the Economic Evaluation part of PVsyst with more options for the Tariffs.
