Factories often choose between buying a system (EPC) and buying solar energy under a PPA. Both can cut daytime cost; contracts and control differ.
EPC in one line

PPA in one line
A provider funds the system; the plant pays for energy under contract terms. Read tariff, access rights, termination, and who repairs faults.
