Thermosiphon systems work on convective mode of heat transfer. The heating of water on large scale is the need of domestic as well as many industrial users. Different kinds of geyser and other devices are available in the market to accomplish this purpose. They use different kinds of energies like electrical, mechanical, chemical etc. and convert it in to thermal energy.

With the evolution of the concept of renewable energy and the development in solar technology, thermosiphon solar geysers are becoming common.
Modes of heat transfer
Generally, there are three modes of heat transfer.
- Conduction
- Convection
- Radiation
Conduction takes place in metals and convection is the phenomenon occurring in fluids. Radiation has something to do with heat transfer through waves. This is the way through which heat of the sun reaches the earth.
Convection in thermosiphon systems
The main working principle of a thermosiphon water heating system is convection. Convection is responsible for uniformly heating any liquid. Here the fluid of our interest is water.
As you know, fluid when heated rises up. The same thing happens in thermosiphon water heating systems. Hot water rises up and the cold water comes down. In this way the whole water is heated uniformly.
The top layers of hot water are then passed to the places where they are desired to be used. The lower colder layers are further heated.
Gravity in thermosiphon systems
Gravity is the second most important factor that plays a vital role in the functioning of a thermosiphon solar water heating system.

With each passing day businessmen across U.S, who were exhausted by paying soaring charges of electricity, are making use of generous discounts& excise credits after installation of Solar powered systems for domestic and business use.
Many states across U.S have taken an initiative regarding this. For instance, California has tendered discount of $4000 per KW of solar power & a 15% excise credit with increased downgrading option.
Contrast to yesteryear’s solar energy systems, which only helped in production of hot water, the new systems in reality generates electricity. Dependable power to function computer systems, cash registers, pumps, cooling, lights & numerous other kind of tools, all this from the power generated by the sun & that too free of cost.
Will I Need to disengage from My Electricity company?

It won’t be necessary to disengage from your electricity company, you will stay connected to them, but you wouldn’t need to use the electricity produced by the, Instead, your business will become a self sufficient energy producer.
Solar powered systems have nearly reached play & play clarity. They are nearly noise free, no decisive monitoring & no parts that may rupture if moved. Solar panels only take a seat under the sun and that’s all that is required to generate energy. As a matter of fact the average solar panel also carries a 25 years warranty and majority of time they are predicted to last twice as much.
Technical Description
Refer to the details above that demonstrates configuration of a solar powered system. On the left if the Solar PV Array which is the energy gathering unit, this will be escalated on the ground, a post or roof top as demonstrated. To get utmost contact with the sun, point the array towards south and tilt it.
The gathered energy will then travel through the wire as DC to your power conversion unit, popularly known as an inverter and invert DC into AC.
The inverter will then orchestrate your AC current that it generates with the electricity companies AC current which will travel via your utility meter and reach the grid. Your actual utility meter will then work unhurriedly as you are generating power, and a lot of times run backwards. If you reside in a “Net Metering State” like California your power supplying company will be obligated to pay you for the production of power.
Are Batteries required for Solar system?
To use batteries or not is something of a personal choice. Battery backed and Battery less systems, both the systems will give the excess energy produced back to the electricity company.
When a power failure occurs then the distinction becomes evident. In a battery less system, if there is a power outage, the system will itself shutdown. There will be no power available until the power company restores it.
Safety Concerns
This has more to do with safety than anything else. During a power failure if a lineman has been sent for repairing, it would be nothing short of dangerous to feed power, when the lineman is working with the mindset thinking that no power is available. For this reason only the system structure makes it unworkable in case of power failure.
The battery backed systems use a completely diverse design. Similar to battery less inverters, the solar panel will feed energy via the company meter until the company’s system is running normally, helping in bill reduction. Read the full story
