Power Ledger Extend Solar Trading Trial

Western Australian based tech company Power Ledger have extended their solar trading trial – let’s take a look at what stage 2 of the company’s p2p renewable trading scheme will encompass.

Solar Trading and Power Ledger

Power Ledger’s blockchain technology has been used since November 2018 to track the transactions of rooftop solar energy traded between 18 households in Fremantle, Western Australia.

The Fremantle Smart Cities project was titled RENeW Nexus and its goal was to demonstrate peer-to-peer energy trading between residential houses. 

Project partners included Curtin University, government-owned retailer Synergy, Western Power, the government-owned network operator, and the City of Fremantle itself.

The trial works by utilising Western Power’s existing network with Synergy’s customers. The Power Ledger platform allows households to buy and sell excess rooftop solar energy in real-time, with residents able to view electricity usage in 30-minute intervals, rather than waiting for their quarterly bill.

Since the trial started in November 2018, Power Ledger has processed almost 50,000 transactions on its platform per month and tracked over 4 megawatt hours of peer-to-peer renewable energy trades. Safe to say it’s been a roaring success, so they’re off to start the second phase of their trial. 

Power Ledger are also working outside of Australia in varied capacity:

  • Silicon Valley Power in the City of Santa Clara alongside Clean Energy Blockchain Network
  • BCPG T77 Thailand
  • Kansai Electric Power Co. (Phase 1)
  • Vicinity Castle Plaza

Saving With Solar Interview with Power Ledger

We had a chat to Power Ledger about the exciting second phase of their renewable energy trading scheme

With ~50k transactions per month currently, what’s the target for 2020?
Power Ledger intends to double the number of participants in the second phase of the trial.

How many trial partners will be involved in stage 2?
In the second phase of the trial we continued to partner with Synergy, Western Power, Curtin University and EnergyOS 
 
Any info on the ‘additional pricing models’ in stage 2? 
The pricing model for stage 2 is similar to stage 1, with some minor tweaks. The partners will be organising workshops and surveying participant to learn more about pricing models. 
 
How much of the trading is automated so the prosumers don’t have to do much?
All the trading is automated. in this deployment however, participants have the option to set their preferred buy and sell prices for peer to peer energy. They can be as active as optimising their prices and trading on a half hourly basis. Alternatively they could go in the platform and set and forget their prices they are happy with.

VPP 2.0 (Virtual Power Plants 2.0)

According to a roadmap for Power Ledger released on Medium last year, the goal is to enact VPP 2.00 – which will allow a lot of options for households who want to trade solar. It also factors in ideas for a two-way electricity grid and options for households to assist the grid – be that through capacity, frequency control, or voltage support.  

We see VPP 2.0, or Virtual Power Plants 2.0, as a natural extension of our peer-to-peer functionality, tying all our other products together. xGrid will evolve into an optimized model of a virtual power plant, to create a conduit for the transaction of value between the owners of distributed energy resources and multiple counterparties.

Self-executing smart contracts will integrate with physical switches in the network, creating an autonomous power market with secure value transfer between consumers, energy markets and networks. For example, a household with solar may normally be trading energy in a P2P market, until they are offered a higher rate by the network to provide capacity, frequency control, or voltage support.

The Planetary Society’s LightSail 2 Solar Satellite

The Planetary Society have launched a solar satellite which has been named the Lightsail 2. The solar sailing Cubesat device will be in orbit for the rest of August. Let’s learn more about the solar sailing technology and what the Planetary Society hope to achieve with the launch of this fascinating new piece of technology!

The concept of ‘solar sailing’ means that an object will be moved by photons escaping the sun’s gravitational pull. According to Popular Mechanics, It’s the second ever solar sailing object to fly – with the solar satellite following IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) from Japan, which launched in 2010. IKAROS certainly has the cooler name, but the LightSail 2 has some superior technology – an aluminzed (a coating of aluminum alloy) Mylar sail and far better uptime.

“For The Planetary Society, this moment has been decades in the making,” said Planetary Society CEO Bill Nye. “Carl Sagan talked about solar sailing when I was in his class in 1977. But the idea goes back at least to 1607, when Johannes Kepler noticed that comet tails must be created by energy from the sun. The LightSail 2 mission is a game-changer for spaceflight and advancing space exploration.”

“We’re thrilled to announce mission success for LightSail 2,” LightSail program manager and Planetary Society chief scientist Bruce Betts said. “Our criteria was to demonstrate controlled solar sailing in a CubeSat by changing the spacecraft’s orbit using only the light pressure of the sun, something that’s never been done before. I’m enormously proud of this team. It’s been a long road and we did it.”

If you’re interest in reading more, the Planetary Society have created a site named Mission Control where you’re able to track the LightSail 2 in space. To visit Mission Control please click here

Solar Panel Degradation | New Software

Solar panel degradation is a big issue, and one of the problems with it is that it can be a bit nebulous to measure, especially if you’re off-site. An Indian university may have some answers with regards to measuring this in a cost and time effective method.

Solar Panel Degradation | Alternatives to on-site inspection.

Parveen Bhola is a research scholar at India’s Thapar Institute of Engineering and Technology. Alongside Saurabh Bhardwaj, an associate professor at Thapar, the pair have developed and optimised statistical and machine learning-based alternatives to enable real-time on or off-site inspection of solar panels to measure the solar panel degradation. This is achieved throughout the usage of clustering-based computation – utilising historical meteorological data to compete performance ratios and solar panel degradation. Factors such as temperature, pressure, wind speed, solar power created, sunshine hours, humidity and historical performance are all utilised to come up with a measurement of the panels’ effectiveness. 

“The majority of the techniques available calculate the degradation of PV (photovoltaic) systems by physical inspection on site. This process is time-consuming, costly, and cannot be used for the real-time analysis of degradation,” Bhola said in a quote posted on TechXplore. “The proposed model estimates the degradation in terms of performance ratio in real time.”

As solar panel technology increases, it’s important that our tools for troubleshooting and optimising their output be improved commensurately; this is a great step for all solar system holders, but especially those in rural areas where having someone come on site is cost and time prohibitive. With this new technique it’s likely that troubleshooting will be more efficient and perhaps even point out problems before they occur.

Solar Cell Windows for sale in Asia

Some amazing technology out of Asia pioneered by Asahi Glass has windows with solar cells embedded in them being offered to the global market. These solar cell windows will be marketed to developers worldwide, with a focus on Australia and Oceania.

Asahi Glass Solar Cell Windows

This technology isn’t new (it has been offered to the Japanese market since 2000), but is experiencing a resurgence as Asahi are preparing the product for export. The windows will be offered for developers to implement as part of construction packages in order to help meet Asia’s rapidly growing renewable power needs.

The solar cell windows can generate 2-4 watt hours per square 15.6cm per side, depending on design. The plan is to sell Sunjoule to construction projects in Australia and the rest of Oceania – they’ve already installed in Cambodia, Singapore, and Hong Kong where they have set up shop to target European and US property developers who want to add unique and eco-friendly functionality to their building designs. They also plan to start producing these energy-conserving solar cell windows/glass in 2018 in Indonesia, according to Nikkei.com. Here’s an article from Inhabitat talking about the ‘nanosolar‘ thin and flexible solar cell coating which is utilised in the panels.
