In the modelling for PV + Battery systems I have clients that are wanting to optimise their energy costs using dynamic energy tariffs such as Octopus Flux. 

This is where they can charge their battery system at night using off-peak rates to use that in tandem with their PV during the day. 

And, as the export rates vary throughout the day if they have a surplus in the battery they could elect when to export and when to charge. 

This maximises the value of the battery and makes the idea of adding a battery, particularly an oversized one more attractive, however I can't see any way to model this within the software, this means that if I create two proposals; one with a battery and one with PV only the latter always has a more attractive RoI, meaning that I have to remove all of that information from the report. 

 

Hi Matthew Stringer

thank you for your valuable input. This is a frequently asked feature request and we put this on top of our list for the upcoming major release this fall. Until then, I can only ask for your patience.

Kind regards

Hello,

Are there any updates regarding the implementation of dynamic energy rates in PVSol. So that it is possible to charge batteries with PV-energy and when the energy rates are low with electricity from the power grid.

Kind regards Joeran

Dear Joeran,

Thank you for your inquiry.

Dynamic electricity prices and the optimised charging and discharging of storage systems from the grid based on a dynamic spot market price cannot yet be simulated in PV*SOL. Our development department is working on a solution.
