What our customers say

«The glass-free solar panels, stainless steel moving parts and galvanised support structure hold up well over the filled septic tanks. The roof retracts and extends as it should and covers 20% of our electricity needs, as expected.»
Curdin Hedinger, Operations Manager WWTP Chur
(Commissioning of the first solar folding roof in 2017/18)

«WWTP Morgental is also a power plant and the new solar folding roof fits perfectly with our strategy. When the sun shines, we have solar power and can save the gas for bad weather or the night. It all runs automatically. We are very satisfied and can only recommend the solar folding roof.»
Roland Boller, Managing Director WWTP Morgental

«dhp technology does a great job - from acquisition to installation. If the commissioning and aftersales also work so well, I'm speechless.»
Roman Bieri, Operations Manager WWTP Langmatt
