Design and Sizing of Solar Photovoltaic Systems

When the amount of energy generated by a grid- connected PV system exceeds the customer''s loads, excess energy is exported to the utility, turning the customer''s electric meter backward. Conversely, the customer can draw needed power from the utility when energy from the PV system is insufficient to power the building''s loads.

How to do Thermal Energy Storage

To determine the load that the chiller will run during the "storage periods", we must remember that we now only have 16 hours per day to run the chiller. During the storage periods, we must make enough "cold storage" (and probably a little more to have a surplus) to "coast" through the peak periods of the day.

Cooling Load Calculation

Typically 5-15% is through transmission loads. This is the thermal energy transferred through the roof, walls and floor into the cold room. Heat always flows from hot to cold and the interior of the cold room is obviously a lot colder than its surroundings, so heat is always trying to enter the space because of that difference in temperature.
