The article presents the results of a 13-year tests and analysis of performance and energy and electrical charge yield for typical photovoltaic modules made of different absorbers. Modules were installed on the south wall of Opole University building (at kard. B. Kominka Street). Registered in this period (2001-2013) values energy and charge of tested modules are presented in reference to 1 Wp their nominal power and to 1 m2 of PV modules. Their annual and monthly distributions, with particular emphasis on the seasonal changes of its parameters and phenomena of aging and degradation of the PV modules structure were shown. In the final part of the article was presented an economic analysis of the profitability of investment in 20 kWp grid connected PV system with and without implemented the program to support investment in renewable energy, which respect to the newly implemented in Poland Act on RES.

Introduction: The exposure of gestating mothers to physicochemical factors may be associated with increased risk of multiple sclerosis (MS) in offspring. Method: The aim of this study was to determine whether solar radiations (SOR), ultraviolet B (UVB) rays, total ozone concentration in the atmosphere (TOCA) and air temperature (AT) during pregnancy are associated with MS developing in offspring. Demographic and diagnostic data including month of birth of 436 MS offspring (M – 171, F – 265), deceased in the year 2007 were derived from the Central Statistical Office in Warsaw. Information on previous SOR, UVB, TOCA and AT in Poland in the scattered years (1931–2007) was obtained from the Institute of Meteorology. Results: Longer exposure to SOR and higher level of UVB during maternal gestation were associated with the smaller number of MS offspring; linear regression test: r = –0.598, p = 0.040 and r = –0.587, p = 0.035. TOCA and AT during gestation were not significantly correlated with the number of MS offspring: r = –0.280 (p = 0.830) and r = –0.437 (p = 0.104). However, decreased TOCA during birth month of offspring was significantly associated with the smaller number of children destined to develop MS: r = +0.631, p = 0.028. Conclusions: Longer gestational exposure to SOR and more intense UVB were associated with lower risk of MS in offspring. Reduced risk of the disease was also correlated to decreased TOCA during month of offspring birth.

Wprowadzenie: Wystawienie matek podczas gestacji na fizykochemiczne czynniki może wiązać się z większym ryzykiem stwardnienia rozsianego (SM) u potomstwa. Metoda: Celem badania było ustalenie, czy radiacja słoneczna (SOR), promieniowanie ultrafioletowe B (UVB), całkowite stężenie ozonu w atmosferze (TOCA) i temperatura powietrza (AT) podczas ciąży wiążą się z rozwojem SM u potomstwa. Demograficzne i diagnostyczne dane obejmujące miesiąc urodzenia 436 dzieci (M – 171, K – 265) z następowym SM zmarłych w 2007 roku otrzymano z Głównego Urzędu Statystycznego w Warszawie. Informacje o przeszłym SOR, UVB, TOCA i AT w Polsce w rozproszonych latach (1931–2007) uzyskano z Instytutu Meteorologii. Wyniki: Dłuższe wystawienie na SOR i wyższy poziom UVB podczas matczynej gestacji wykazały asocjację z mniejszą liczbą potomstwa z SM; test liniowej regresji dał następujące wyniki: r = –0,598, p = 0,040 i r = −0,587, p = 0,035; TOCA i AT w ciągu gestacji nie korelowały istotnie z liczbą potomstwa chorego na SM: r = −0,280 (p = 0,830) i r = −0,473 (p = 0,104). J ednakże z mniejszające s ię T OCA w miesiącu u rodzenia p otomstwa z SM i stotnie w iązało s ię z mniejszą liczbą dzieci, które później zachorowały na SM: r = +0,631, p = 0,028. Wnioski: Dłuższe gestacyjne wystawienie na SOR i na bardziej intensywne promieniowanie UVB wykazało asocjację z niższym ryzykiem SM u potomstwa. Zmniejszone ryzyko choroby korelowało także z niższym TOCA w miesiącu urodzenia.
