Inverters - a key sub-system

We list the supplier of the inverter because it is a crucial subsystem, not just for converting DC to AC, but often also for 'power tracking' to hold the solar arrays close to their peak power point.

Many suppliers now produce inverters specifically for the solar market.

The EPC contractor will normally select the supplier and procure the inverters.

Basis of the data used

The data used for the analysis and the table on the left is derived from operating projects of 4MWAC+ on the Wiki-Solar Database, according to these criteria.

Inverter suppliers are identified against 20.5% of the operating capacity on the Wiki-Solar Database (of which these top 21 account for 17.8%). The total capacity for Inverter suppliers listed may therefore be on average up to 5 times that identified here (though some do confirm details of their portfolio to Wiki-Solar).

Some suppliers in this list also fulfil other roles in utility-scale projects, as EPC contractors for example. The figures quoted here apply only to their inverter supplies. Where companies have maps, however, these will show all their projects.
