Solar panel cleaning
The National Renewable Energy Laboratory estimates that solar panels lose up to 25% of their energy output due to the accumulation of leaves, dirt, dust, pollen, moss, sap, bird droppings, and water spots. Cleaning your solar panels regularly pays for itself in the return you'll see on your energy output by maintaining the rated capacity of your system. Glass Tech is a local Big Island based company offering solar panel washing. We clean all brands of photovoltaic systems and solar hot water panels - residential and commercial, large and small. Our solar panel cleaning system is completely safe for people and our environment - it's just pure water acting as a solvent with no soaps or harmful chemicals. The water we use goes through a five stage filtration system so it won't leave water spots, and it's pH is neutral so it won't corrode aluminum frames. It is 99.99% pure water that has been deionized and demineralized through reverse osmosis - so it attracts impurities and washes all dirt and debris away naturally.
hard water stains
Glass restoration - hard water stain removal

Hard water stains in Hawaii are those unsightly clouds of water spots on glass left behind by both misaligned sprinklers and on glass shower doors - both very common problems. To understand why normal window cleaning techniques will not remove these stains please refer to a technical bulletin "The Systematic Cleaning & Restoration of Architectural Glass".

Glass Tech will remove the stains by either a chemical process and cleaning, or for more severe water deposits, by using the same polishing process we use to remove scratches from glass. You will have crystal clear glass again.
