When will we be able to model a battery and PV system without demand load?


Recommended Posts

In the UK there are now huge grid connection constraints for grid export only solar PV systems with export limits frequently imposed. Faced with needing to shift power to limit export and stay inside the DNO cap, battery storage is the obvious route to go as this can peak shave generation without the need for down regulation in many cases. Why can't PVSOL allow me to simulate a PV plus battery storage system with a grid export limit where there is no on site demand load?

PVsyst allows this but isn't as user friendly as PVSOL. 

Quite a lot of the new release features PVSOL includes periodically are of little or no value and I struggle to understand why time has been spent adding minor tweaks for domestic scale PV systems when the issue I have highlighted is a very frequent occurrence for PV designers and installation companies in the commercial scale system sector.

Surely it isn't that hard to write a program to simulate diverting surplus generation into battery storage for later export to grid?
