Storage Tanks and Solar Collectors

Solar water heaters mostly require a well-insulated storage tank that have an additional outlet and inlet connected to the collector. The solar heater that comes with two-tank system, preheats the water before it enters the conventional water heater. Whereas, in the one-tank systems, the back-up heater combines with the solar storage in one tank.

There are three types of solar collectors:

Flat-plate collector: Flat-plate collectors are insulated, weather-proof boxes that has a dark absorber plate under one or more plastic (polymer) or glass covers and are usually glazed. The unglazed flat-plate collectors are mainlyt used for solar pool heating purpose as it has a dark absorber plate, made of metal or polymer, without a cover or enclosure.

Integral collector-storage systems: Also known as batch systems or ICS, they feature one or more black tubes or tanks or in a glazed insulated box. Cold water passes enters the solar collector to preheat and then the water passes on to the conventional backup water heater to provide you hot water. These are best for the mild-freeze climates as water in the outdoor pipes could freeze in extremely cold weather.

Evacuated-tube solar collectors: They come with parallel rows of transparent glass tubes in which each tube contains a glass outer tube along with metal absorber tube that is attached to a fin. The solar energy gets absorbed by the fin's coating but prevents radiative heat loss. These solar collectors are best used for U.S. commercial applications.

Solar water heating systems should have a backup system for cloudy days and conventional storage water heaters are usually used as backup or these maybe a part of the solar water heater system package.
