The aim of this paper is to present a theoretical and experimental analysis performed for a solar hybrid collector composed by a photovoltaic collector assembled with an active cooling device (solar absorber and a serpentine cooling coil). The photovoltaic part is composed by a sandwich of three parallel layers: glass cover exposed to the solar rays, thin layer of photovoltaic cells, and on underside, a suporting glass sheet. The active cooling device follows this last glass layer, and can be placed in contact or not with it. This thermal system is a black painted copper flat plate absorber having coupled with an welded serpentin tube. Inside this copper tube, water is made to flow under a constant rate and in the laminar regime. The theoretical model considers at each time intervals of 30 minutes (when solar irradiation is almost constant), a steady state thermal balance by conduction for this set of parallel layers. The Poisson equation is considered for the photovoltaic layer cells where heat and electricity are generated. The Laplace equation are considered for the other layers. The boundary conditions assume at each layer interface an identity of temperature and heat flux. The solution for this theoretical model was obtained by means of the software MATHEMATICA. For the hybrid solar collector are determined: the temperature of the several layers, inlet and outlet temperatures, heat fluxes and thermal and photovoltaic efficiencies. Also, is analysed a system of 10 collectors in series-paralel, if it is required a home application in Rio de Janeiro. Also, an experimental model (a collector of 0,5 m2 was tested under the local conditions, being presented the obtained temperatures and efficiencies. A comparison of these experimental results with those from the theoretical model are presented.
