In this post, we take a detailed look at 3 solar technologies that will have the biggest impact on the solar industry over the coming years.
2020 new solar technology — where are we headed?
When most people hear the words ‘solar power’ they instantly think of good ‘ole solar panels on rooftops or in a solar farm in the desert. And with good reason: traditional utility-scale and rooftop solar panels have dominated the solar market until this point.
But there are now several exciting new solar panel technologies either in the pipeline or already on the market. These promising technologies will revolutionize the way we think about not just solar, but energy production in general. Solar no longer requires large parcels of land or roof space, nor does it need to look boring. Read on to find out more.
#1 Floating solar farms (aka ‘ floatovoltaics ’)
Silicon panels are becoming cheaper and more efficient day-by-day. According to experts, if photovoltaic panels are placed on reservoirs and other water bodies, they offer even greater efficiency as well as a plethora of other benefits.
“Floatovoltaics” are photovoltaic solar power systems created for floating on reservoirs, dams, and other water bodies.
Floating solar farms can generate huge amounts of electricity without using valuable land or real estate. The installation costs of floating photovoltaic panels are less than land-based photovoltaic panels. Also, research showed that the power production of floating solar panels is greater by up to 10% due to the cooling effect of water.
Besides producing clean solar power, floating solar farms can help with water management. They reduce the loss of water to evaporation as they limit air circulation and block sunlight from the surface of the water. Also, floating solar farms prevent noxious algae production, lowering water treatment costs. Furthermore, the water beneath keeps solar panels clean and minimizes energy waste.
In 2008, the first commercial 175 kWh floating panel system was installed in California at the Far Niente winery in Napa Valley.
#2 BIPV solar technology
Building-integrated photovoltaics, as the name suggests, seamlessly blend into building architecture in the form of roofs, canopies, curtain walls, facades, and skylight systems. Unlike traditional solar PV panels, BIPV can be aesthetically appealing rather than a compromise to a building’s design.
Of course, aesthetics alone is not enough for solar buyers; economics matters too. The good news is that the BIPV solar panel systems enable homeowners to save on building materials and electric power costs. By substituting BIPV for standard building materials, you can cut down on the additional cost of solar panel mounting systems.
BIPV technology, when used on the building’s facades, atrium, terrace floor, and canopies, provides the following benefits:
Increased energy efficiency
High thermal and sound insulation
Clean and free power output from the sun
Decreased O&M costs
Zero carbon footprint
The photovoltaic PV glasses installed as building materials act as an energy-generating device, allowing natural light inside homes and offices, just as conventional architectural glasses.
#3 Solar skins
Solar skins are a novel PV technology to integrate custom designs into solar panel systems. The solar skin technology is similar to the ad wraps displayed on bus windows.
Sistine, the manufacturer of solar skins, is testing the technology at the United States National Renewable Energy Laboratory to increase its efficiency. Solar thin-film skins maintain high efficiency due to its selective light filtration advancements. The sunlight falling on solar skins is filtered to reach the solar cells beneath it. As a result, it simultaneously displays the custom image and provides solar energy.
These imprinted custom images, embedded into solar panels, can exactly match your grassy lawns or rooftops of your homes.
Solar skin panels can also be beneficial for businesses or government offices. They can be customized to display business logos, business advertisements, a country’s flag, and so on.
Moreover, solar skins utilize rail-less racking systems, sit lower, have a sleek finish, and hide metal components, giving the panels a super cool look. If panel aesthetics stops you from going solar, Sistine’s SolarSkins might be the solution you are looking for.
In addition to these benefits, Sistine Solar enables you to monitor your system performance 24/7 on your phone. It also provides you alerts in case of any issues or solar energy outages, and prescribe the right remedies at the right times.
Solar power was earlier generated only by means of ground-mounted or rooftop panels. But thanks to all the advancements mentioned above, solar is set to become lighter, more flexible, and applicable everywhere.
Imagine all this tech is available and you visit another city. You can buy food at a solar-powered food cart, eat it while traveling on a solar-powered highway, and charge your phone from your solar-powered clothes. This is what the near future looks like!
And there are actually lots of other innovative residential solar technologies in development or currently being rolled out in 2020. Perhaps the most promising new tech is Perovskite solar cells, which could soon be used to create solar paint.
Solar energy is the technology used to harness the sun’s energy and make it useable. As of 2011, the technology produced less than one-tenth of one percent of global energy demand.
Many are familiar with so-called photovoltaic cells, or solar panels, found on things like spacecraft, rooftops, and handheld calculators. The cells are made of semiconductor materials like those found in computer chips. When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity.
On a much larger scale, solar-thermal power plants employ various techniques to concentrate the sun’s energy as a heat source. The heat is then used to boil water to drive a steam turbine that generates electricity in much the same fashion as coal and nuclear power plants, supplying electricity for thousands of people.
How to Harness Solar Power
In one technique, long troughs of U-shaped mirrors focus sunlight on a pipe of oil that runs through the middle. The hot oil then boils water for electricity generation. Another technique uses moveable mirrors to focus the sun’s rays on a collector tower, where a receiver sits. Molten salt flowing through the receiver is heated to run a generator.
Other solar technologies are passive. For example, big windows placed on the sunny side of a building allow sunlight to heat-absorbent materials on the floor and walls. These surfaces then release the heat at night to keep the building warm. Similarly, absorbent plates on a roof can heat liquid in tubes that supply a house with hot water.
Solar energy is lauded as an inexhaustible fuel source that is pollution- and often noise-free. The technology is also versatile. For example, solar cells generate energy for far-out places like satellites in Earth orbit and cabins deep in the Rocky Mountains as easily as they can power downtown buildings and futuristic cars.
Solar energy doesn’t work at night without a storage device such as a battery, and cloudy weather can make the technology unreliable during the day. Solar technologies are also very expensive and require a lot of land area to collect the sun’s energy at rates useful to lots of people.
Despite the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains inefficiency. Japan, Germany, and the United States are major markets for solar cells. With tax incentives and efficient coordination with energy companies, solar electricity can often pay for itself in five to ten years.
The solar industry needs to act proactively to ensure efficient use of water for cleaning of solar panels and justify the ‘environmentally-friendly’ tag, consulting and research services provider Bridge To India said Wednesday.
The statement has come against the background of an advisory issued by the New and Renewable Energy Ministry (MNRE) on optimal utilization of water by the sector for cleaning of solar panels.
“This is a belated acknowledgement of the increasing water risks faced by the solar sector…,” Bridge To India said in a statement, and added that rightly, MNRE has refrained from mandating use of any specific technology.
The firm further said that it is common industry belief that solar modules require two cleaning cycles per month to reduce soiling losses to a level of 1 per cent. However, actual water consumption varies widely depending on water availability, cost of water, location of power plant and level of environmental consciousness, amongst other factors.
“Around 56 per cent of installed solar capacity in India is located in arid and high water-stress zones, exposing them to a high level of water risk,” it said. For projects located in areas with good availability of water, wasteful use of water is a common problem.
The problem is exacerbated by the fact that around 60 per cent of solar installations use ground water, sometimes illegally, Bridge To India added. As increasing number of cities in India are facing water crises, wasteful use and/ or illegal use of water is a growing concern in the sector, it said. “The solar industry should act proactively to ensure efficient use of water and justify the ‘environmentally friendly’ tag,” it said.
Bridge To India added that there are proven and affordable technologies providing water efficient solutions including anti-soiling coatings robotic cleaning and hydrophobic and nanotechnology based self-cleaning, amongst others.
New Delhi: The first general assembly of the International Solar Alliance will be held in India this October. The historic event is expected to coincide with the birth anniversary of Mahatma Gandhi, signalling that New Delhi would employ the first treaty-based international government organization in India as a foreign policy tool.
As part of India’s strategy to cement its leadership among developing countries, the marque event is expected to be attended by representatives of 65 countries which are signatories to the framework agreement. The general assembly follows International Solar Alliance’s founding conference, co-hosted by India and France, in New Delhi in March.
“Of the 65 who have signed the International Solar Alliance, 35 countries have ratified it. It takes time as it goes to their respective Parliaments for approval. The first general assembly will be a big event,” said one person aware of the development, requesting anonymity.
Other prominent intergovernmental organizations in the energy sector include the Vienna-based Organisation of the Petroleum Exporting Countries (Opec) and Paris-based International Energy Agency (IEA).
Speaking at a press conference earlier this month, power minister Raj Kumar Singh had said that the ministers from the 65 countries will be attending the first general assembly of the International Solar Alliance. India has taken a lead in this and the other countries have recognized it, he added.
The general assembly will also witness the election of the office-bearers of the solar alliance of countries that was mooted by Prime Minister Narendra Modi during the India-Africa Summit in Delhi in October 2015. Besides, it will also provide a platform for the member-countries and investors to court and seek opportunities.
India has been looking at ways to leverage International Solar Alliance, which includes an ambitious outreach programme by reaching out to chief executives of Fortune 500 companies and starting a Solar Nobel prize, Mint had reported on 9 August, 2017.
International Solar Alliance’s mission is to undertake joint efforts required to reduce the cost of finance and the cost of technology, mobilize more than $1,000 billion of investments needed by 2030 for massive deployment of solar energy, and pave the way for future technologies. “There will be a process of engagement,” said the person quoted above.
The International Solar Alliance has been working on a $300-billion risk mitigation fund as part of a strategy to create a sustainable financing architecture for solar projects worldwide. The fund will be used to insure solar power projects against risks such as default in payment by electricity procurers, foreign exchange fluctuations and regime change. This, in turn, will help attract investors to the space.
While queries emailed to India’s ministry of external affairs on Thursday evening remained unanswered, a spokesperson for ministry of new and renewable energy told Mint that the newspaper’ queries have been referred to International Solar Alliance.
“We will let you know the dates and rest of the details once we have official word in place,” an International Solar Alliance spokesperson said in an emailed response.
It was India and France who front-ended the attempts to set up International Solar Alliance and launched it on the first day of the United Nations conference on climate change held in Paris in November 2015. While initially, International Solar Alliance envisaged 121 sunshine countries situated between the Tropics of Cancer and Capricorn as its members, it was later announced that the membership of the body will be thrown open to all countries that want to join, with no criteria such as duration of sunlight and geographical location.
