Renewable power sources like solar and wind present a challenge for grid operators: balancing intermittent production with power users’ needs. Facilities that produce solar power on-site face a similar challenge. While facilities can draw power from the grid to balance demand that shoots higher than solar production, they’re likely paying more for that power than they need to, which undercuts their solar investment. That’s why, if you’re considering solar, you should also consider a demand management system (DMS).
One advantage of solar power is that production is fairly regular, barring inclement weather and depending on the location (unlike wind, which is highly dependent on weather patterns). For example, you might be able to rely on solar power kicking in at 7 a.m. and dying at 6 p.m. on most days. But there’s some variability within that window, and in some cases the solar power will drop off and the facility will start drawing grid power during the utility’s highest peak period. In short, if your facility has a fairly steady demand level and you add solar, you’ll decrease peak demand, but you’ll probably also introduce some variability.
