FAQ 

Question

What is solar water heater?

Answer

Solar water heater or solar hot water systems comprise several innovations and many mature renewable energy technologies that have been well established for many years. Solar water heater has been widely used in Australia, Austria, China, Cyprus, Greece, 

Question

What is the Collector?

Answer

Collector - A solar collector is not really a solar water heater. A solar water heater is a system which may include a tank, pump, controller and solar collector panel. A solar collector is that part of the system which absorbs the sun's energy and converts it into heat.

Question

How is the Solar Collector Efficiency measured?

Answer

Efficiency: Solar collector efficiency is usually expressed as a percentage value, or in a performance graph. When assessing a collector's performance make sure it is based on the correct surface area values. Eg. If performance values are based on gross area, then the gross area must be used when determining total heat output. IAM values have a significant influence on actual heat output throughout the day, and should be considered. Looking at just the percentage efficiency value will not give a true indication of daily heat output.

Question

What is a heat-pipe?

Answer

Heat Pipe: An evacuated rod or pipe used for heat transfer.

Question

What is Insolation?

Answer

Insolation: Don't confuse this with insulation - the one letter change makes a big difference. Insolation refers to the amount of sunlight falling on the earth.

Question

What is Insulation?

Answer

Insulation: The ability to protect against transfer of heat/cold. Solar collectors use compressed glass wool or polyurethane insulation to insulate the header from heat loss. Glass wool has excellent insulation properties, is very light and can withstand high temperatures, making it an ideal choice for a solar collector. It is made from a least 80% old glass bottles and can be recycled so is very environmentally friendly.

Question

What is Irradance?

Answer

Irridance, Irridation: Basically the same as Insolation

Question

What is IAM?

Answer

Incidence Angle Modifier (IAM): refers to the change in performance as the sun's angle in relation to the collector surface changes. Perpendicular to the collector (usually midday) is expressed as 0', with negative and positive angles in the morning and afternoon respectively. Collectors with a flat absorber surface, only have 100% efficiency at midday (0'), whereas solar tubes provide peak efficiency mid morning and mid afternoon, at around 40' from perpendicular. This results in good stable heat output for most of the day. What is the Aperture? The part of the collector through which light enters. For evacuated tubes this refers to the cross-sectional surface area of the outer clear glass tube measured using the internal diameter, not the outside diameter.(Eg. 0.0548m x 1.72m = 0.094m2). 1.72m is the exposed length of the evacuated tube.

Question

What is Absorber?

Answer

Absorber: The part of the collector that actively absorbs the light rays. For solar tubes this is defined as the cross-sectional area of the inner tube (selective coated) measured using the outside diameter. (Eg. 0.047 x 1.72m = 0.08m2) This value is used when calculating efficiency values. For solar tube collectors with reflective panels, the entire circumferential surface area of the inner tube is often used when calculating absorber area, as the reflective panel is supposed to reflect light onto underside of the evacuated tube.

Question

Are Vacuum Tube Collectors Better than Flat Plate?

Answer

Flat plate thermal solar collectors have been in use for several decades, but only in relatively small numbers, particularly in Western countries. Evacuated tubes have also been in use for more than 20 years, but have been much more expensive than flat plate, and therefore only chosen for high temperature applications or by those with money.In recent years the production volume of evacuated tubes has exploded, resulting in greatly lower manufacturing and material costs. The result is that evacuated tubes are now similar in price to flat plate, but with the insulating benefits of the evacuated tube, they are set to become the default choice for thermal solar applications worldwide.
