These collectors heat liquid or air at temperatures less than 80°C. Flat-plate collectors are used for residential water heating and hydronic space-heating installations. Figure 3 shows the schematic of a typical solar system employing a flat plate solar collector and a storage tank.
This study analyses aspects of the design of flat plate solar collector networks, including network configuration and the effect of fouling, with the goal of improving efficiency in solar energy capture and reducing operating costs.
The high hardness of water, elevated temperatures, and low flow velocity are factors that promote scaling formation. However, proper control of these variables can mitigate the drawbacks caused by this type of fouling. Several studies have addressed the design and optimization of flat plate solar collectors and collector fields.
Work of Hottel and Woertz in 1942 and by Hottel and Whiller in 1958 can be looked as a first work on solar flat plate collector. They had developed the collectors consisting of a black flat plate absorber, a transparent cover, heat transfer fluid and an insulating case.
For well-insulated collectors or concentrating collectors the stagnation temperature can reach very high levels causing fluid boiling and, in the case of concentrating collectors, the absorber surface can melt. A way to describe the thermal performance of a Flat Plate Solar collector has been shown.
Due to complications in numerical methods, authors developed an analytical model to simulate the thermal behaviour of flat plate solar collector operating in forced convection. A solution for energy equation was developed for a fluid flow inside the collector, based on the Green's function method.

Flat-plate collectors are the most common solar collector for solar water-heating systems in homes and solar space heating. A typical flat-plate collector is an insulated metal box with a glass or plastic cover (called the glazing) and a dark-colored absorber plate. These collectors heat liquid or air at temperatures less than 80°C.
