It took 8,500 men working two shifts every day for six months — and three shifts for two months — to finish, ahead of schedule, the Adani Group’s giant solar power plant in southern India.
The vast, 10 sq km project in Ramanathapuram, in the southern state of Tamil Nadu, is the world’s largest solar power station in a single location, according to the company.
It has the capacity to power 150,000 homes — and it is one sign of how serious India is becoming about meeting its renewable energy targets.
Considering the delays that commonly bog down infrastructure projects in India, the speed at which the 648 megawatt project was completed demonstrates the country’s commitment to renewables, said an analyst.
“The government is very clear about its solar plan, and large installations are key to this plan,” said Aruna Kumarankandath of the Centre for Science and Environment in Delhi.
Prime Minister Narendra Modi “is a real evangelist”, and has prioritised solar to meet the renewables target, she said.
As a signatory to the Paris Agreement on climate change, India is committed to ensuring that at least 40 percent of its electricity will be generated from non-fossil-fuel sources by 2030.
While coal still provides the lion’s share of India’s energy, officials forecast the country will meet its Paris Agreement renewable energy commitments three years early — and exceed them by nearly half.
A 10-year blueprint released last month predicts that 57 percent of total electricity capacity will come from non-fossil sources by 2027.
Solar energy is a particular focus. It makes up 16 percent of renewables capacity now, but will contribute 100 gigawatts of the renewable energy capacity target of 175 GW by 2022.
Of that 100 GW target, 60 percent will come from large solar installations. The government is planning 33 solar parks in 21 states, with a capacity of at least 500 megawatts each.
India’s ambitious targets come at a time when renewable energy is at a turning point in the country, as generating electricity from renewables costs nearly the same as from conventional sources.
The urgency also aims to fill a gap: India is among the world’s fastest growing economies, yet one-third of its households have no access to grid power.
The renewables goal will help ensure “uninterrupted supply of quality power to existing consumers and provide electricity access to all unconnected consumers by 2019”, according to the blueprint.

The Rs 3 per unit or USD 4 cents tariff is unprecedented in Indian rooftop solar sector that has drastically reduced pricing dynamics, said Amplus Energy Solutions.
Solar tariff has fallen to an all-time low of Rs 3 per unit, which was quoted by Amplus Energy Solutions in an auction for rooftop solar power conducted by Solar Energy Corporation of India (SECI). “In a move that will offer cheapest power from solar rooftop plants, Amplus Energy Solutions has won a bid to install 14.5 MW of solar rooftop plants across 10 states. The tariffs offered are at a record low of Rs 3/unit in three states and Rs 5.3-6.2/unit in other states in India. Tariffs are fixed for 25 years,” Amplus Energy Solutions said in a statement.
The Rs 3 per unit or USD 4 cents tariff is unprecedented in Indian rooftop solar sector that has drastically reduced pricing dynamics, it said.
Uttarakhand, Himachal Pradesh and Puducherry will get solar at Rs 3 per unit, while others such as Karnataka, Madhya Pradesh and Maharashtra will get solar power at Rs 5.56/unit. Rajasthan at Rs 5.38/unit, Haryana at Rs 5.76/unit and Punjab at Rs 6.20/unit, it added.
The capacities bagged by Amplus under this bid are Maharashtra (3MW), Rajasthan (2MW), Punjab (2MW), Karnataka (2MW), Haryana (2MW), Himachal Pradesh (1MW), Madhya Pradesh (1MW), Uttarakhand (0.5MW), Puducherry (0.5MW) and Chandigarh (0.5MW), it said.
Solar rooftop plants will be identified and installed on buildings of NGOs, educational institutes, hospitals, trusts and not for profit companies etc. in these states, it added.
Gurgaon-based Amplus will install, operate and maintain the project for a period of 25 years and will invest Rs 70 crore for all the projects.
These projects would help in CO2 savings of 5,00,250 MT or reduced consumption of 36,97,500 barrels of crude oil which will be equivalent to planting 6,23,500 trees over their entire life.
Amplus is also in the process of closing loans worth Rs 200 crore from the SBI – World Bank lending facility for rooftop projects, it said.
The company is on a rapid growth path and is looking to further expand its geographic footprint in India and hire resources. It currently employs more than 100 people with offices in 5 major cities across India.
Going forward, Amplus has plans to achieve 100MW of solar rooftop projects in this fiscal year with 60MW already clocked with this latest win.
In a short span of time, Amplus is already serving more than 30 clients in more than 200 locations in India.
Speaking about this project, Amplus Energy Managing Director & CEO Sanjeev Aggarwal said “With this win, we will be able to offer solar power at unprecedented prices to deserving consumers.
The government aims to increase energy sourced from solar rooftop systems to 40 gigawatts by 2022.

One in seven homes in Australia has solar panels on their roof — more than anywhere else in the world. So what is going on in all those shiny rooftop structures?
The first solar cell was made in 1839 by 19-year-old Edmond Becquerel, who noticed electricity was generated by a piece of silver chloride when it was illuminated with light.
It was less than 1 per cent efficient, but we have come a long way since then.
The first 20 per cent silicon solar cell was made in Australia 30 years ago by Andrew Blakers and Martin Green at a time when solar energy was largely a fringe technology for hippies and space agencies.
The research findings from the lab back then are now being implemented in solar-panel manufacturing plants all around the world.
A solar cell is a device that converts sunlight into electricity.
The most common type of solar cells are made from wafers of ultra-pure silicon and boron that have been infused with phosphorus in a hot furnace, coated with an antireflection coating, and then fired with metal contacts.
They are typically about the size of a birthday card, but less than half a millimetre thick.
At the heart of a solar cell is a tiny electric field that splits negative charges from positive charges using the energy of sunlight.
In a silicon wafer solar cell, the electric field is set up with the help of small amounts of other atoms. On one side of the wafer are some boron atoms (with one less electron than silicon) and on the other side are phosphorus atoms (with one more electron). Together they create what is called a positive-negative (p-n) junction. Opposites usually attract, but the p-n junction forms the electric field that is able to drive positive and negative charges apart.
When sunlight is absorbed by the solar cell an electron is knocked free inside the silicon and pushed across the wafer due to the electric field. It can then be collected by metal contacts to become usable electricity.
It is an incredible invention — the only way we make electricity on Earth at scale, without any moving parts.
Alongside their price, what we often care about is their efficiency — the amount of electrical-energy-out divided by sunlight-energy-in.
The ones on rooftops today are around 20 per cent efficient.
When sunlight shines on a solar panel, the DC electricity that it produces is transported by conducting wires into an inverter, which transforms the electricity into the 240V AC supply that we use to power our telly and fridge.
The efficiency records for solar cells are continually increasing.
Researchers have achieved 39 per cent efficiency for normal sunlight and an impressive 46 per cent for concentrated light the equivalent of 300 suns (when we focus sunlight from a larger area with a bunch of mirrors) in the lab, but these cells are smaller than a CD, designed for space, and made with very expensive materials.
The improvements are thanks to the use of new material combinations, advanced anti-reflection coatings, clever semiconductor processing that avoid electrical losses, and a hundred other smart engineering ideas.
The world’s mass-producers of solar cells are continually incorporating these advances into their own solar cells, meaning that the panels on rooftops are steadily getting more efficient too.
The techniques that made the world’s first 20 per cent silicon solar panels 30 years ago are just now being translated into the production lines of the world’s largest solar panel manufacturers.
Thirty years from now, we should be able to expect the same from research advances happening in the lab today.
In 20 years’ time the solar panels on your roof will probably look the same as now with their aluminium frame and glass front, but they will likely be a whole lot cheaper and at least half again as efficient thanks to smart engineering.
A range of new technologies being researched now in labs across Australia and the world may overcome the efficiency limits of silicon-only solar cells.
One of the exciting developments in the field is a new semiconductor called “methyl ammonium lead iodide perovskite”.
Solar cells made out of this cheap and easy to produce material have already achieved 20 per cent efficiency in the lab — matching the efficiency of today’s silicon cells.
In the future, perovskites may either replace silicon solar cells or be used as a companion material to help them move beyond 26 per cent efficiency — the upper limit of silicon-only cells.
The research team I am part of at Monash University and CSIRO is experimenting using perovskites as the top layer in double-decker “tandem” solar cells that absorb different colours of sunlight in each layer.
In a tandem solar cell, high-energy photons (green, blue and UV) are absorbed in the top layer, and low-energy photons (red, orange and yellow) are absorbed in the bottom layer. This allows the solar cell to squeeze more energy out of sunlight — we are aiming for double the efficiency of rooftop solar cells at super low cost.
Other ideas being pursued around Australia and the world include reflected-tandems (double-decker solar cells placed side by side), quantum-dot solar cells (using tiny nanocrystals as the energy absorber material), up-conversion of light (converting two low-energy photons, that would otherwise be wasted, to make one high-energy photon) and hot-carrier cells (collecting charge from solar cells before they have the chance to lose any voltage).
It is not too hard to imagine a future with thin, efficient, lightweight and flexible solar cells on mobile phone cases, laptop bags, backpacks, suitcases, hats, tents, you name it…
It takes about two to five years for a solar panel to “pay back” the energy that went into making them (depending on how sunny it is where you live). This includes the energy needed to mine the silicon and process it into a solar cell, and also make the aluminium frame and glass in the panel module housing.
Solar panels usually come with a guarantee of 80 per cent output for 25 years (and there is no reason why they should not last longer), which means energy-wise solar panels are a good thing, by a factor of at least four.
Silicon is the second most abundant element in the Earth’s crust (second to oxygen in the silicon dioxide that makes up sand and quartz), so there will not be any material shortages in the foreseeable future.
Solar panel recycling stations are starting to be set up all over the world — like aluminium recycling, silicon is an excellent candidate for cradle-to-grave-to-cradle material management.
And sunshine itself is the most sustainable resource we have — the sun should be around for a few more billion years at least.

As ingenious and environmentally friendly as solar energy solutions are, they’re not always as efficient as we’d like them to be – and of course, they’re only generating new electricity when the Sun is out. But an international team of scientists has come up with a new type of energy system they’re calling ‘hydricity’, which combines the power of sunlight with hydrogen fuel.
There are two ways we get energy from the Sun: photovoltaic cells (the panels you see on rooftops) and solar thermal power plants, which concentrate the Sun’s rays, then use the generated heat to warm up water and drive turbines using the steam that’s produced. The latter method captures more of the Sun’s solar spectrum, but is less efficient than a standard solar panel, and can only work in direct sunlight – which is why you only find them in parts of the world that get plenty of sunshine.
This is where hydricity comes in. By combining solar thermal power plants with hydrogen fuel production facilities, the researchers say, efficiencies in both types of power can be improved. An integrated system would produce both steam for generating electricity immediately, and hydrogen for storing it for later use – a crucial consideration as the countries of the world become more dependent on renewable energy.
The team, from Purdue University and Switzerland’s Federal Polytechnic School of Lausanne, says it can produce hydrogen at an efficiency of 50 percent and electricity at an unprecedented 46 percent efficiency, thanks to the way the high-pressure turbines can be used to run in succession of the lower-pressure ones.
Over the course of an average 24-hour cycle, it’s claimed that hydricity could reach a Sun-to-electricity efficiency of 35 percent, which is as good as the best multijunction photovoltaic cells combined with battery power.
The hydrogen fuel produced alongside the electricity is important: not only could it find uses in transportation, chemical production and other industries, it doesn’t discharge when stored or degrade with repeated use. When the Sun goes down, the stored hydrogen power could kick in, and that means turbines don’t need to be stopped or restarted.
“The concept provides an exciting opportunity to envision and create a sustainable economy to meet all the human needs including food, chemicals, transportation, heating and electricity,” said one of the researchers, Rakesh Agrawal from Purdue. “Traditionally, electricity production and hydrogen production have been studied in isolation, and what we have done is synergistically integrate these processes while also improving them.”
So far, the scientists have only produced simulated models of the process – the next step is real-world experiments. The group’s work has been published in Proceedings of the National Academy of Sciences.

Solar water heating systems almost always require a backup system for cloudy days and times of increased demand. Conventional storage water heaters usually provide backup and may already be part of the solar system package.
A backup system may also be part of the solar collector, such as rooftop tanks with thermosyphon systems. Since an integral-collector storage system already stores hot water in addition to collecting solar heat, it may be packaged with a demand (tankless or instantaneous) water heater for backup.
INSTALLING A SOLAR PV SYSTEM
article-why-solarThe heart of a Solar PV system is the grid-interactive inverter. The inverter takes electrical power generated by solar cells, converts it from direct current(DC) to alternating current (AC), and supplies it for household electrical consumption. Excess power generated during the daytime hours is fed back into the utility power grid. When the amount of power generated by the solar panels is insufficient for the home’s needs,the system draws needed energy from the utility power network (or from an optional battery bank.
