In the CAPEX solar model, a business invests in and owns its solar system, paying the upfront installation cost. A Solar EPC Company manages the design, equipment supply, and installation.

In the OPEX solar model, a third-party developer invests in and maintains the system, while the business typically pays for the electricity it uses under an agreed contract.

Professional Solar EPC Contractors offer Solar EPC Services for both models, helping businesses choose the right option for Commercial Solar Installation or Industrial Solar Installation based on their budget and energy needs.
