Flat Plate Collector (FPC):
This kind of solar collector is somehow different from evacuated tubes collector. It consists of a dark flat-plate absorber with pipes attached, a glass transparent cover, a heat-transport fluid and a heat insulating backing. Flat plate solar collector is the most common type used at home and in many other fields not only for commercial but also for agriculture. It is easy to install on roofs or facades of a building and it costs less maintain charge. For home use, the flat plate solar collector housing has more advantages than the other one. The most significant one is that using solar energy is much cheaper than using gas or electricity for family.
The simple and beauty design helps it apply to various installations and easy to combine with buildings. Stainless steel solar geyser with a flat plate solar collector usually loses less heat to the environment. The glass cover plate outside which has strong light-admitting quality can reduce heat losses and it is strong enough even in bad weather. However with high temperature resistance, the thick thermal insulation material within can effectively decrease moisture absorption of the collector and keep permanent performance of the solar geyser.
With high efficiency, flat plate solar collector housing can help a stainless steel solar geyser provide heat more consistently and it can be more reliable, stable than evacuated tube collector even in some areas without much sunshine. When the water heated above 80 degrees, the flat-plate solar emery system can balance the temperature itself and keep you from scalding. In conclusion, a little knowledge about the differences between flat plate solar collector and evacuated tube collector may not make you become a professional solar energy expert, but knowing this can provide a framework in which to understand the specification of a stainless steel solar geyser of your house and to evaluate its effectiveness
The latest is certainly not always the greatest, so which is actually better – a flat plate solar hot water system or one that uses evacuated tube collectors? While evacuated tube technology is more of an investment, the benefits certainly outweigh the cost. Any additional cost may also be offset by solar hot water rebates!
Evacuated tube collector based systems:
- Capture sunlight better as they have a greater surface area exposed to the sun at any time
- Are more efficient in transferring heat
- Can be used in subzero temperatures
- Are durable and if a tube should be broken, it can be easily and cheaply replaced.
- Provide excellent performance in overcast conditions
- Require a smaller roof area than comparable flat plate collectors
Do not have the same level of corrosion problems as flat plate collectors
