Grand installThe Bar Harbor Grand Hotel has a large hot water system designed to cover 40-50% of their seasonal hot water needs. With thirty flat plate collectors and a 2000 gallon storage tank this system produces a massive amount of hot water. Hot water can be a very expensive component of a hotel's bottom line. Customers expect clean sheets and hot water above all else. So putting 2000 gallons of hot water in front of the hot water maker guarantees the Grand saves money and has happy customers. In addition, there is a clear marketing advantage to letting customers know their hot water was made using less fossil fuel.

SEA install, KitteryThis install in Kittery Maine is both solar hot water and electric.
The Hot Water system above is made by Velux. Velux is unique because the collectors are mounted directly on to the roof deck just like a skylight. There is no exposed racking or plumbing. This system is two flat plates and a 120 gallon tank with electric backup. The Solar electric is a 2100 watts grid tied system.

Crossroads House In Portsmouth NH has a large solar hot water system installed on their brand new building. On the roof are 16 flat plate collectors and they are connected to a 900 gallon storage tank. The data below shows temperatures at the cold input to the collectors, the hot output from the collectors, the tank temperature, the hot water temperature leaving the tank and the solar output. Even this winter we are seeing tank temperatures that will substantially lower their hot water fuel bills.
