Comparison between FPC and ETC

S No

Evacuated Tube Collector (ETC)

Flat Plate Collector

1

Quick heat Generation

Slow heat Generation

2

Heat absorbing surface is always perpendicular to the sun-rays because of the cylindrical collector glass tube. Hence peak absorption always.

The collector fins and tubes being flat, the incident sun-rays will be at 90 degrees
only at noon. So the peak absorption is also only during this time.

3

Vacuum inside the collector tube reduces heat loss at night

Heat loss will be more in collector panels at night.

4

Negligible scaling of tubes -can be cleaned manually (Inner dia 37 mm).
Consequent loss of efficiency is minimum.

Heavy scaling of copper tubes which cannot be cleaned manually as bore dia is
12.50mm, causing substantial loss in the efficiency of the system.

5

Satisfactory performance in cold conditions.

Performance falls significantly on cloudy and winter days

6

Increment in temperature from ambient temperature is 100c to 500c on clear sunny days.

Increment in temperature from ambient temperature is 10°c to 40°c.

7

Advanced technology at a competitive price.

Outdated technology, high price.

Frequently Asked Questions (FAQ)

A solar geyser relies on solar power, which is a source of renewable energy, to work. For a solar water heater to work it requires a set of solar collectors to absorb the solar energy. These collectors are then connected to an insulated tank that stores the hot water. When the sun is out, water is heated in the solar collectors which is then pumped or flown automatically through the thermosyphon principle to the storage tank.
As a solar geyser works on solar power, it cancels out the need for electricity. Let’s take for example a solar water heating system that has a 100 litre per day capacity. This solar geyser saves up to 1500 units of electricity in a year. However, this is subject to the amount of hot water that has been generated. But what’s more important is that it can also save around 140 litres of diesel thereby reducing CO2 emissions. A solar water heater is very useful in areas that experience power cuts. As this solar water heating system is designed with a storage unit, it can provide hot water as and when required. A solar water heater is an one time investment and a lifetime of savings because it runs on the principle of renewable energy.
As the tank in a Aadhi Solar solar water heater is insulated with high-density injected PUF insulation, it ensures maximum heat retention. PUF with insulation properties is twice as effective as any other insulation material. This guarantees that the water remains relatively hot.
With Aadhi Solar’s solar geyser, you will be able to enjoy warm water even during the colder months or when the sky is cloudy. This is due to the diffused radiation readily available in the atmosphere. During winter season, if there is clear sunlight, the water will be hotter. One way of ensuring hot water and direct sunlight throughout the year is by positioning the solar water heater correctly at the time of installation.
No, since solar water heaters are generally installed on rooftops or open grounds (where direct sunlight is available) you are not required to make any plumbing changes.
No, Aadhi Solar offers installation services. Installation of solar water heaters should be done only by experts. Call our customer service number for more details.
Aadhi Solar’s range of solar water heaters come with a 5-year warranty along and a dependable service. We also ingrain our products with features that ensure their durability like equipping the water heaters with a Duronox SS 304 L tank that ensures resistance against corrosion, a rustproof Zinc Allu sheet for stronger outer body and a Magnesium Sacrificial Anode that protects the tank from corrosion by forming a layer of magnesium on the inner tank.
