The kind of EPC you choose depends on the size of the solar plant you plan to put up.

Let us assume the developer wants to set up a 1 MW solar plant.

Typically, larger EPCs focus on large solar projects (5 MW and above). They are less keen on getting involved in smaller projects and even if they do, they charge a premium. This doesn’t go well with most customers who are cost conscious.

On the other hand, smaller EPCs who focus on residential and small C&I rooftop solar plants may not have the resources to complete a 1 MW solar plant.

So, the sweet spot for the developer is EPCs who specialize in 1-5 MW solar plants. They offer the expertise as well as the matching cost expectations of the customer. Moreover, unlike large EPCs, they are able to offer a higher degree of flexibility by catering to specific requirements (probably some customizable features) of the customer.
