There is no single solution for renewable energy in the commercial and industrial (C&I) space today. Every system is unique, depending on load profile, available space, budget, grid constraints and many other factors. The implementation of a renewable energy system is a business decision that begins with a question: What do you want to achieve? The answer to that question informs the direction that the installation will take.
Often, the answer relates to the energy grid, and specifically to how much independence a business wants from it. Companies need power and, in the past, had no other choice than to buy 100% from the grid. The solar industry is offering alternatives that provide different degrees of independence from the grid, both commercially and in terms of supply reliability.
Five degrees of freedom
1. Grid-tied solar without storage
For a long time, a simple grid-tied solar system was the standard in C&I installations, just like in residential spaces. Solar modules mounted on roofs provide power to the facility only when the sun is shining and the business is using electricity at the same time. Any excess is exported to the grid, if allowed, and deficits are covered by the grid. In this way, a noticeable amount of energy is produced locally, bringing cost savings and supporting ESG goals. The installation and system layout are usually simple and the investment is manageable.
