Read MoreThe main objectives are to compare the energy production of different solar photovoltaic systems over two years (2015 to 2016) and to assess the performance of PVsyst and SAM simulation software
Read MoreWe used the PVsyst software, that allows to perform simulations of PV systems including battery storage, and that provides detailed hourly simulation results that were used as input for our analysis. The software also includes a tool to perform a financial evaluation and the output includes these economic variables.
Read MoreSuch an evaluation has to be performed hour-by-hour, as the energy exchanges are instantaneous. Therefore, this requires the definition of the User''s needs
Read MoreStand alone system definition. Stand-alone systems are always organized around a battery storage: - a PV array charges the battery or directly delivers its power to the user. - the user''s needs (consumption) should be well defined, with its daily profile (i.e. in hourly values). At each hour, the simulation performs a balance between the PV
Read MoreSimulation. The battery will have a daily cycle: it will always be empty at the end of the night, and will be charged only during good days. After the simulation, the balances of all these energy flux will appear on the loss
Read MoreHi, Such an evaluation has to be performed hour-by-hour, as the energy exchanges are instantaneous. Therefore, this requires the definition of the User''s needs hourly profile as input parameter. In the project''s dialog, the self-consumption will be activated as soon as you define a valid user''s needs profile.

Read MoreThe simulation of PVsyst doesn''t take this capacity diminution along the years into account. This is not very important, as the Capacity is not a crucial parameter during the system running: a variation of 20% has a very low effect on the final performance.
Read MoreThis energy balance is controlled by a controller. The role of the controller is to handle the energy flux, mainly for the protection of the battery: - When the battery is full, the PV array should be disconnected. - When the battery is empty, the user should be disconnected. Stand alone systems in PVsyst don''t yet allow multiple orientations
