Valentin Software has updated the market-leading design software PV*SOL and PV*SOL premium and adapted the programs to reflect the latest developments in the market.The result is that the detailed design, visualization and in particular yield calculation of photovoltaic systems has become even more relevant.
New lithium-ion battery model for battery storage systems
In both variants, PV*SOL is now equipped with its own new mathematical model for lithium-ion batteries, which enables the precise simulation of storage systems with lithium-iron-phosphate and lithium-nickel-oxide batteries. Lithium batteries, as the most important batteries used in the German storage market, are therefore now included in the yield calculation. In addition, complete battery systems offered on the market are available in the PV*SOL database.
Exact simulation with minute values
Today, PV systems have to meet the high requirements of network operators and system owners. As a result, new properties have become important, such as the behavior of 70% power-clipping, inverter oversizing or the interaction of PV systems with storage. These properties can be calculated exactly with PV*SOL, because the simulation can now be optionally performed with minute values. Calculations with hourly values, which were usual up to now, are no longer accurate enough for these new requirements.
