Solar Water Heating Technical
The principles of solar water heaters is very simple! Solar Water Heating uses solar evacuated collectors to capture the sun's radiant energy and converts it in to thermal heat. The solar heat is then either transferred to usable energy or stored in a heat sink such as a large solar water tank or concrete slab and released as needed. There are many types of solar thermal systems but the most advanced and efficient system is a closed loop pressurized system. This type of system allows the suns energy to be stored and released upon demand using sophisticated controllers and pumps that allows home owner the comfort and control with virtually zero energy costs.
BE WARNED! Modern day solar collectors produce significant amounts of heat energy and advanced high temperature solar system should be properly engineered. Northern Lights Solar Solutions provides pre-packaged solar heating systems that are proven successful through out the world. Caution should be used with "Home Made" Solar systems as they can lead to serious damage especially if using high efficiency vacuum tube collectors. Our systems are engineer with to provide maximum performance with SAFETY 1st!
Most solar water-heating system have four main parts: (1) a solar evacuate tube collector and (2) a solar storage tank (3) Solar Controller and Pump Station (4) Special Solar Piping. Until recently the most common collector used in solar hot water systems was the flat panel collector. However with the advance in technology, solar vacuum tube technology is rapidly becoming the method of choice as its energy output is much higher and takes up less space per square foot. Mass production of solar tubes has driven the cost down to allow widespread use of vacuum tubes.
The tank can be as simple as a modified standard water heater, but more specific solar water tanks are recommended for better performance. Most solar water tanks will also feature a back up electric element built into the unit.
The brains of every solar water heating system is Solar Controller and Pump Station. This includes all items required to make the system function optimally and safely. Items such as temperature controllers, pumps, expansion vessels, pressure safety valves, fill and drain spouts all part of a properly installed solar system. Northern Light's uses German engineered and designed PAW pump stations with integrated RESol controllers.
