Still managing projects in different tools, copying data manually between systems, and sending reminders one by one because nothing is connected? That sounds familiar.
Many installation companies start looking for PV*SOL alternatives when they realize that simulation alone is not enough anymore. You also need smooth sales processes, clear project management, automation, and full visibility across your team.
At the same time, projects are becoming more complex. According to the European Commission’s energy performance framework, digital documentation and structured planning are becoming increasingly important across technical industries. And as highlighted by the International Energy Agency (IEA), system integration and efficiency are now key priorities in modern energy projects.
So the real question is: do you just need software to calculate systems – or do you need software to run your entire business?
If you’re searching for a practical PV*SOL alternative, here are 10 tools worth looking at.
