Leading utility-scale solar inverter producers
The most recently published list of inverter suppliers is shown below. It is likely that each supplier shown has delivered far more than this list indicates, because the identity of the inverter supplier is not frequently published - see note on the right.
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 9.3% of the operating capacity on the Wiki-Solar Database (of which these top 21 account for 8.6%). The total capacity for Inverter suppliers listed may therefore be on average up to 10 times that identified here..
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.
