What to watch out for - Performance modelling

There is a range of software used for performance modelling. The level of accuracy of this assessment varies depending on the type of software used as well as the panel and inverter product being measured. Other factors that affect the accuracy include the quality of site specific data such as weather conditions.

Key Tip 1

When the real life performance of the panels and inverter is taken into account to create a business case, the best performing technology will deliver better financial outcomes.

Key Tip 2
