I already know that advanced simulation can give the irradiance on plane by hourly data. Recently, a customer wanted to evaluate the possibility of growing crops after building a photovoltaic power plant. So here comes a problem, plant growth requires light, air, soil, water, and temperature. Let us assume that air, soil, water, and temperature can be solved, I want to see the Total quantity and spatial distribution of irradiance on the ground, and the ground is under PV arrays at specific heights and spacings. Can pvsyst have this function? And where can I learn the operation steps? This problem has troubled me for a long time. If there is any other software or method that can solve this problem, please tell me. Best regards!

This will be very helpfu?

Transposition factor tool can help. And this video showed the way to set batchsimulate paraments csv file. Even so, I failed to find a way to restrict the simulated duration to a specific month. Though I change the simulation dates,the BatchResults still performed an annual result. Can u tell me how to set simulate duration rightly? Best regards!

this page can calculate the irradiance in different tilt angle on summer or winter,how can I calculate the irradiance in different tilt angle on a specific month?

So I'm trying to find the best tilt for a seasonal adjust system. I already known the way to find best tilt angle on summer or winter,in " Grid Conected-Variant-Orentation-fixed tilted plane". But I cannot find how to get the best tilt on every month or season,like the best tilt on October or spring. Is PVsyst able do this? A lot thanks.
