In order to overcome this challenge, energy storage systems and new control strategies are needed to smooth the fluctuations of solar energy and ensure consistent cooling output. However, integrating energy storage with solar cooling systems and their interaction with load requires a considerable initial investment.
Solar absorption cooling with cold storage configurations The main hardware of a solar absorption cooling system with a cold storage configuration consists of a solar collector filed, absorption chiller, cold storage tank, and plurality of pumps for circulating the working fluids, as shown in Fig. 10.
A solar-based cooling system uses solar energy, in the form of heat or electricity, to provide cooling for air conditioning and/or refrigeration. The energy from the sun is captured using solar photovoltaic (PV) and transformed into electricity to drive vapor compression AC systems.
The deployment of solar-based thermal cooling systems is limited to available solar radiation hours. The intermittent of solar energy creates a mismatch between cooling needs and available energy supply. Energy storage is, therefore, necessary to minimize the mismatch and achieve extended cooling coverage from solar-driven cooling systems.
Like other thermal systems, modeling of solar absorption cooling systems can be categorized broadly into steady-state, quasi-steady state, and dynamic approaches. The steady state modeling is an approach where the system behavior is modeled considering all variables and parameters constant over time.
Therefore, our design does utilize a method for storing energy for cooling as needed. The combined air conditioning and thermal storage system is intended as a technology to increase the effectiveness of solar photovoltaic energy use.

Thermal energy from the sun can be stored either as latent heat or sensible heat. Sensible heat has to do with the heat capacity of a material. The added thermal energy stored in a material manifests as an increase in temperature. Latent heat is heat that is transferred due to changes in the phase of a material. [4] .
