Young people, not only because of its energetic, but also because of its ecological advantages, should mostly use solar energy. Wisdom of utilization of solar energy should be acquired at schools, both from stories and books and by personal experiences. Plants for demonstration of operation of PV systems for supply of small consumers (bulbs, public — address systems and computers) would be natural way of adoption of simple rules.

If every hundredth out of the existing 4.104 elementary, 512 secondary and 135 advanced schools and faculties in SCG would install one educational-demonstration mini 300 W PV system, installed power rating of 14 kW would be obtained.

Beside the schools, sports centers are the places where healthy youth gathers. Should on every tenth object of existing 2,141 outdoor and 1,853 indoor sports objects (out of which 582 are sport halls and 85 indoor swimming pools) similar demonstration PV systems for lighting or some other useful purpose be installed, electric power of about 120 kW would be obtained.

Assuming actually attainable variant, the following dynamics of installation of educational-demonstration PV systems in schools and sport centers is anticipated (Table 8.).

Next European basketball Championship will be organizing in Serbia and Montenegro (Novi Sad, Vrsac, Beograd and Podgorica). It would be a real chance for accelerating of solar cells utilisation, similar as Sidney Olimpics in Australia (2000) [11]. This mean instaling relatively larger dimension of PV systems. Further, some of that PV systems will be Grid-connected, why not. In that case, one should be carefull for component cost optimizing [12]!
