It is designed with planning, monitoring and visualisation of renewable energy systems in mind. The programme provides a meteorological database of 2000 international locations as well as simulation parameters of all solar modules, inverters and thermal collectors that are available on the market.

The new version includes measurement data of thin-film solar cells, in addition to that of crystalline solar modules.

As the shape of the IV curves of solar thin-film cells has stronger irradiance dependence than crystalline cells, they require more parameters for the simulation process.

“With our newly developed analytical model, we have managed to reduce the failure rate of simulating thin-film modules to about zero percent,” says Jürgen Schumacher, Founder and Managing Director of doppelintegral.
