The project participant primarily responsible for the construction of the solar generating station
Wiki-Solar's participant lists are all compiled consistently from its Database of utility-scale solar projects. If your company should be (higher) on the list, go to this page for further details.
Remember these figures are based solely on the output (AC) capacity of operational projects over 4MWac.
Here is the latest list of top EPC contractors. See maps of the projects of some with the EPC pull-down above.
This project partner is primarily responsible for the Engineering, Procurement and Construction of the plant. This usually includes selecting the suppliers of solar modules, inverters and other key items of equipment; and finalising and underwriting the final design and output projections for the plant.
While fulfilling the role of prime contractor, many EPCs will in turn appoint sub-contractors to handle much of the construction work; typically divided between mechanical and electrical activities.
The EPC contractor is usually appointed by the project developer or the owner (though a company may fulfil more than one of these roles).
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.
The EPC contractor is known for some, but not all, of the projects on Wiki-Solar's database. Therefore, as noted below the table some figures will be under-stated. However, several of the leading participants confirm details of their portfolio to Wiki-Solar (and you can too - see the left of this page).
Because capacity is included in these figures only when the plant is connected, the total capacity now fully and partly constructed by many of those listed will be higher.
Some contractors in this list also fulfil other roles in utility-scale projects. The figures quoted here apply only to their construction activities. Where companies have maps, however, these will show all their projects.
