energeticka navratnost solarnych clankov

[Jan Waclawek]

Tak som ten spominany clanok nasiel, nie je to nic prevratne, a takychto bude asi vela, ale su tam zaujimave vety:

"The $1 per watt is very realistic [...]. No one else comes close at this point."
($1 na watt je velmi realisticke [odhadnuta cena ich CdTe panela]. Nikto iny sa tomuto ani len neblizi.

[T.j. kedze ide o tvrdenie vedca o este nefungujucej tovarni, realita bude mozno $1.5, a ak je pravda co tvrdi, je to sucasny strop. Nehovori to tam, ale urcite sa jedna o Wp (watt-peak, maximalny vykon). Ako sme sa uz doobeda bavili, znamena to viacmenej obsah energie, pri velkoobchodnej cene okolo 30-100$/MWh (napr. http://www.eia.doe.gov/cneaf/electricity/epav1/wholesale.html a aj inde) to znamena energeticku narocnost asi 15-50kWh/Wp; pri vyprodukovanej energii (pre CR/SR z mnohych zdrojov) 1kWh/Wp/rok je energeticka navratnost 15-50 rokov.]



"Will your technology be directed toward individual homes or large-scale projects such as solar “parks”?

Right now there’s no shortage of takers in large utility-scale installations, so that’s where AVA will start.
[...] We’re looking toward gigawatts of manufacturing."

Budete vasu technologiu smerovat na individualne domy alebo velke projekty ako su solarne "parky"?

V tomto okamihu nie je nedostatok dopytu po velkych energetickych instalaciach, takze tam AVA zacne.
[...] Predpokladame vyrobu v rade gigawattov.
