I have 4.8Kw grid tie with demand monitor and control. We set demand control as 5.5kw; between 6-8pm, there seems to be not enough sun and the demand control turn off AC before it reaches to 79 degrees, which is what we set. The room temp is around 82-83 degrees in this time frame. The price for demand charge is around $17/kw with SRP in Arizona. If we set it higher, the cost using solar will be higher than regular plan.
I am looking for a way to boost power between 6-8pm so we can stay comfortable but still get some benefit from solar system.
