TL;DR: In this article, the authors present test results on hybrid solar systems, consisting of photovoltaic modules and thermal collectors (hybrid PV/T systems), and show that PV cooling can increase the electrical efficiency of PV modules, increasing the total efficiency of the systems.

TL;DR: In this article, the authors constructed and tested flat plate solar collectors with colored absorbers for water heating applications, including collectors in their typical form with the protective glazing, and also collectors without glazing.

TL;DR: In this article, integrated collector storage (ICS) solar water heaters with stationary compound parabolic concentrating (CPC) reflectors are designed and test results are presented, which aim to achieve low cost systems with improved performance by the reduction of their thermal losses and the increase of water temperature rise by using the nonuniform distribution of solar radiation on the absorber surface.

TL;DR: In this article, two low-cost CPC solar collectors were designed, constructed and tested, which consist of two separate absorbers, which are horizontally incorporated in a stationary asymmetric CPC mirror.

TL;DR: In this paper, two types of ICS solar water heaters were designed, constructed and tested, which consist of two cylindrical storage tanks, which are connected in series and are horizontally incorporated in a stationary asymmetric CPC type mirror.
