What Is A Cast Monosilicon Solar Panel?

July 1, 2019 | 273 views

Silicon is the Queen of solar power. Some people say Coal is King, but I say our Queen can kick your King’s arse. Only 5 years ago thin film cadmium telluride1 panels were still being installed on home roofs, but they have disappeared from the residential market leaving silicon to rule the roost with an iron beak.2 While Silicon is Queen, not all silicon is the same. There were two big silicon princesses3that have been battling for market share. Polysilicon is quick and cheap while monosilicon is more expensive but also more efficient.4 But now there is a new contender that’s made in a container — cast monosilicon! Cast monosilicon5 – or cast monocrystalline silicon if you’re being paid by the word — has been around for years but didn’t make a splash6 until recently when the process was improved. It is now almost — but not quite — as efficient as monosilicon, while being almost — but not quite — as cheap as polysilicon. It has the advantage of lower LID, which is a type of solar cell degradation, and the less there is of that the better.

A vision for renewable energy

Article | June 8, 2022

Right now, renewable energy makes up a very small part of the entire energy sector of Bangladesh. But as we move into the future, and concerns about the environment become too great to ignore, exploring cleaner and greener sources of energy becomes the need of the hour. Our economy is booming, and our population is growing, so it goes without saying that our energy requirements are immense. There is plenty of scientific evidence that burning fossil fuels indiscriminately is not sustainable in the long term, so we do need to up our game in looking at alternatives.

2020: The Year of Convergence in Corporate Renewables

Article | July 29, 2022

The rapid growth of corporate renewable procurement has been nothing short of a buyer-driven revolution in the United States’ electric sector. Almost 20 gigawatts (GWs) of corporate power purchasing agreements (PPAs) were completed in 2019 across the globe, up from 13 GWs of corporate PPAs in 2018 and triple the numbers from 2017.1,2 And the majority of this growth has come from the United States. Fortunately for those of us committed to renewable energy, we expect this trend to continue. But as should be expected in such a dynamic, buyer-driven sector, we are starting to see some noticeable shifts in the marketplace as it evolves and grows. I wanted to highlight some of the trends Constellation is watching for this year.

2020 Trends That Will Make Waves In The Energy Industry

Article | June 14, 2022

In the renewable world, energy is generated by weather and the amount of energy that can be produced depends on the current conditions. Energy storage can ensure a power supply is maintained when weather conditions are not optimal for generating energy. While energy storage products have already been introduced to all levels of the market there are several technology hurdles to overcome before energy storage will reach maximum potential. We believe there will be great advancements in 2020 on:

Solar Power, Great For The Environment? Or Is It The Last Thing We Need?

Article | February 10, 2020

Solar power is an undeniably a green, renewable form of electricity generation - but many organisations with questionable motives (even here in New Zealand) are trying to persuade the public (and Government – hi lobbyists!) that solar power isn’t that environmentally friendly, and that it's even harmful. At the expense of bullish corporate profits, solar power is often thrown under the bus. This article lists the facts - putting an end to the negative spin on solar so often found in the media. When solar panels produce power, they do not; create any air pollution, use zero water, create carbon emissions, noise pollution, and they won’t disturb surrounding ecosystems. Solar power is a renewable energy source, the sun’s rays are infinite, fill your boots.

Capstone Green Energy Secures Order for C1000S Microturbine for Industrial Dairy Plant in Colombia

businesswire | June 01, 2023

Capstone Green Energy Corporation , a global leader in carbon reduction and on-site resilient green Energy-as-a-Service (EaaS) solutions, announced today that Supernova Energy Services SAS, its authorized Distributor in Colombia, has secured an order for a C1000 Signature Series microturbine. The system will be operated at an industrial dairy alongside an Alfa Laval steam boiler evaporator, producing 6,200 lbs. of steam per hour. Alfa Laval AB is a Swedish company founded in 1883, providing specialized heat recovery products, and is a Capstone Green Energy approved Network Partner for heat recovery systems. It is expected to be commissioned in October 2023. “For operations like a dairy where any loss of power can result in product waste, the reliability of a Capstone microturbine makes it a natural choice. This is particularly true in locations where electricity from the grid is relatively unreliable. Confidence in Capstone’s reliability combined with the turbine’s low maintenance requirements and compatibility with other technologies, like the steam boiler being used here, continue to prove the value of Capstone’s modular design and engineering as well as its versatility for use in multiple industries,” said Capstone Green Energy President and Chief Executive Officer, Darren Jamison. The Capstone powered energy system will run on high-pressure natural gas (HPNG) to provide power for the dairy’s pasteurization operations. The Alfa Laval boiler will provide steam for the entire plant. Reliability was the top reason the customer selected Capstone, but they indicated that minimal maintenance needs and low emissions were also factors in their decision. The microturbine and steam boiler combination will replace the grid-sourced electricity and a natural gas boiler that the dairy is currently using to run its operations. This is the first dairy that Supernova has worked with in Colombia and the first to use steam rather than absorption chillers in its processes. “Working with a customer who is willing to take a different approach to powering their operations is exciting. Once we knew that reliability was their top priority, the Capstone microturbine was the obvious choice. By combining the Capstone turbine with the Alfa Laval steam boiler, this customer has found an innovative solution that will give them more operational predictability and reduce product waste,” said Nestor Moseres, President of Supernova Energy Services SAS. About Capstone Green Energy Capstone Green Energy is a leading provider of customized microgrid solutions and on-site energy technology systems focused on helping customers around the globe meet their environmental, energy savings, and resiliency goals. Capstone Green Energy focuses on four key business lines.
