Solar Water Heaters

Using solar energy

To heat water is an effective way to use Australia’s abundant sunshine, save energy, save money and reduce greenhouse gas emissions. Solar Water Heaters (SWHs) make up around 13 per cent of all hot water systems used in Australia.

Installation is important and depending on your location, direction of solar panels and the amount of water you use, a SWH could provide 50 to 90 per cent of your hot water needs.

What is a solar water heater?

A solar water heater uses energy from the sun to heat water for your home. Solar panels on your roof collect energy from the sun’s rays to heat water which flows to a storage tank, ready for use.

There are many different types and configurations of solar water heaters available. It is important to select the type that is most suitable to your family size, climate, house type, roof characteristics, water quality, available space and aesthetic preferences.

How does it work?

Cold water flows from the tank to the solar collector, usually positioned on your roof. In a split system like the one shown below, cold water is pumped up to the collector. In a thermosiphon system where the tank is mounted on the roof above the collectors, cold water flows naturally into the collector because it is heavier than hot water.
The solar collector is made of materials that absorb heat from the sun very efficiently. The cold water travels through the collector and the heat in the collector heats up the water, which returns to the tank
Hot water rises to the top of the tank and colder water is taken from the bottom and returned to the solar collector. When you use hot water, it is taken from the top of the tank where the water is hottest.

The two most common types of SWHs are close-coupled thermosiphon systems and split systems. Consumers can choose between many component types to suit the needs of the home. Generally you can select:

Boosting options
Gas (natural or LPG)
Electric
Collectors
Flat plate panels
Evacuated tube collectors
System configuration
Thermosiphon
Split systems
Electronic controls

Close-coupled thermosiphon

The solar revolution on India’s rooftops is gaining momentum.

The country added more rooftop solar power capacity in the last financial year than in the previous four years combined, making it the fastest-growing segment in the country’s clean energy space. During the financial year 2017, some 715 megawatts (MW) of systems were added, up from 227 MW in the previous year, taking the country’s total installed capacity to 1.3 gigawatts (GW, 1 GW = 1,000 MW) according to a report (pdf) by Bloomberg New Energy Finance (BNEF). By 2022, the report estimates that the country will have around 9.5 GW of rooftop solar capacity—but that is still substantially short of the Narendra Modi government’s target of 40 GW.

This has happened largely because rooftop solar power is now cheaper than commercial and industrial power in all major Indian states, according to BNEF. Besides, costs have halved over the last five years. Overall, because of increased competition and low solar panel prices, setting up rooftop systems has become cheaper than the global average by between 39% and 50% in India.

“If a mall is purchasing power from (a) grid at Rs8-9 (per unit)…going by (the) rooftop model, the power cost will be half of that. So it is a viable proposition,” Gautam Bafna, an analyst at CARE Ratings who tracks the renewables sector, told Quartz.

Government incentives and policies to push rooftop solar installations have also contributed to the growth over the last year, Bafna added. For instance, the government has held auctions to have companies set up over 1 GW of rooftop projects in the first nine months of 2017.

Meanwhile, the size of installations is getting bigger as well. The average size of a rooftop system has increased from 250 kilowatts (kW) in 2015 to 855 kW in 2018, according to BNEF. This is due to better utilisation of rooftop space and consumers’ willingness to use power generated from their own buildings rather than purchase the power from elsewhere, the report said.

90 percent energy self-sufficiency almost reached

Solar energy efficiency.
With a combination of a 34 kW photovoltaic installation, energy storage, and a small wind turbine energy pioneer Andreas Haehnel reaches over 80% energy self-sufficiency. An electric heating system electric car charging is integrated.

“Not for me!”, said Andreas Haehnel. In a land where the conventional electric power system looms over the energy landscape as the mighty Roman Empire once did over its vast domains, Mr. Haehnel’s house in the Bavarian town of Burgthann stands out like a small, rebellious Gallic town, evoking the image of the heroic Asterix from the well-known European comic strip of the same name. In this same spirit, Mr. Haehnel has taken it upon himself to be a pioneer in the movement toward renewable energy. And for this undertaking he is relying on Fenecon Technologies.

The Challenge
Independence is a noble goal for many people. However, when it comes to self-sufficiency in the area of power generation, it is not that easy. “It simply was and still is not”, explains Mr. Haehnel. “I have invested a lot of time and money together with my project partner in order to get to where I am today: nearly 90% self-generated power. Integrated yet decentralized power generation is, in my opinion, the best strategy for bringing about my own personal energy transformation.” As an employee at a regional brewery, Haehnel is no expert in the area of power generation. He is, nevertheless, what you might call a man of conviction. He places great value on maintaining a high quality of life.

And technological solutions are indispensable toward this end. Not only does this project require will and knowledge, but the wide range of potential solutions and combinations of technologies presents a challenge to those interested, because there exists such a large variety of providers when it comes to power sources; the conversion into household electricity as well as its storage or management; and the necessary consultation for such a project. It was clear to Haehnel from the very beginning that the project would require a great deal of personal initiative and that he would have to rely on trustworthy partners in order to profit from their experience and knowledge.

Own personal energy transformation

As for his own knowledge, Haehnel applied the learning-by-doing method, along with skills learned in a partial apprenticeship as an electrician. His enthusiasm for electricity and renewable energy can also be seen in his appearances as a tester of electric cars on YouTube. Even his house, which he built in 2000, was configured to facilitate his own personal energy transformation. The “energy rebel” laid out the following basic functions required for his home: transportation using electric cars, 90% self-sufficiency for electricity consumption and heating from an intelligently operated renewable energy supply management system, which he hopes to use as a model for other buildings.

Two storage systems
In order to reach this ambitious goal using solutions from the variety available on the market, Haehnel chose Fenecon. “Our team is very young and engaged, and we were

all very impressed by how much energy Andreas Haehnel brought to the project.”, declared Franz-Josef Feilmeier, CEO of Fenecon. The dimensions that Mr. Haehnel specified for the solutions are considerable: The sun is to be the main source of energy tapped by a photovoltaic unit with a peak output of 34 kilowatts, the modules of which will face south, west, and even north. Additionally, a small wind turbine will contribute 800 watts of electricity.
