We list the supplier of the solar modules because this is the key sub-system - the one that converts light into electricity.
Most flat panel solar modules applied to utility-scale projects are the same as those used for other applications, though a few are tailored for ground mounted or large-scale applications.
A small minority of projects, however, use concentrator panels, which are only suitable for large-scale free-field applications.
The EPC contractor will normally select the supplier and procure the solar modules.
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.
Solar module suppliers are identified against 22% of the operating capacity on the Wiki-Solar Database (of which these top 14 account for 19%). The total capacity for Solar module suppliers listed may therefore be on average up to five times that identified here.
Some suppliers in this list also fulfil other roles in utility-scale projects, as developers and/or EPC contractors for example. The figures quoted here apply only to their solar module supplies. Where companies have maps, however, these will show all their projects.
