### API calculation SolarFarmer API v5 was released. #### Updates - Support for 110-cell modules (twin 55-cell modules) - Definition of PV system auxiliary losses added - Definition of PV system availability loss added - Voltage derate dependency added - New IAM profile models added - Update of the shading calculation order - LossTreeTimeseries includes night timesteps #### Bug fixes - Report of a shaded gain for an edge case in 3D tracker sites at sunrise/sunset has been fixed. - Invalid azimuth exception in certain 3D fixed-tilt projects. - PVsyst standard format of TMY data did not cope with trailing semicolon characters. - The variable `IL_Oper` in the *PVsystFormatResults.txt* file was incorrect for calculations with different number of MPPT inputs. - The variable `I_Boost` in the *PVsystFormatResults.txt* file did not include efficiency. - The variable `UnavLss` in the *PVsystFormatResults.txt* file had incorrect sign during night timestamps. - Partial column request of PVsyst timeseries results not working for ModelChainAsync endpoint. - Results missing in the *PVsystFormatResults.txt* file when running multi-year calculation in ModelChain endpoint - Calculation with power optimizers with minimum voltage constraints may crash. The handling of IV curves for optimizers with these constraints has been improved.

::o-alert{:dismissible=false variant=info} ::block{class='m-2'} **3D API Private Preview** The 3D API is available on a Private Preview basis to existing customers who want to road test the API whilst we continue to work on API management and scalability. Whilst in Private Preview, the 3D API is available at no additional charge, although we are currently limiting maximum project size to 125MW AC and we are running on a relatively small cloud cluster – which means that you may experience resource contention at busy times.
