Dirk Hufnagel im Interview: Solarwärme nicht schlechtreden!

Foto: Dirk Hufnagel
Solarthemen 502. Vor zwei Wochen hat der Verbraucherzentrale Bundesverband (VZBV) eine Auswertung von bundesweit 1849 Solarwärme-Checks an bestehenden Solarthermieanlagen veröffentlicht und dabei die Mängel an zahlreichen Anlagen betont (vgl. Solarthemen+plus vom 23.3.2018). Solarexperte Dirk Hufnagel, der selbst viele Anlagen auch für die Verbraucherzentrale untersucht hat, findet den Tenor zu negativ. Er meint, dass man die VZBV-Studie auch anders lesen kann. Der Ingenieur hat über 15 Jahre mit dem proKlima-Fonds in Hannover 1500 Solaranlagen gefördert und bundesweit beachtete Qualitätskriterien entwickelt.
