“What is the largest possible scale of energy storage with modern day engineering?”

 

Companies such as Tesla Motors are investing in energy storage like there is no tomorrow. The current frontier is Gigawatt-Hour-Scale Storage. Just to put things into perspective, one gigawatt-hour is enough to power the average California home for over 92 years!

“Why might there be no more ancillary service players in South Australia after Tesla?”

 

California based Tesla Motors recently made headlines by supplying 100 MW of their batteries to the South Australian Hornsdale Power Reserve to help control ancillary services. This project was so efficient that it absorbed 55 percent of all FCAS revenues in South Australia as well as cutting ancillary services pricing by 90 percent. Analysts say that this has been so efficient that it is possible that there will be no more room for competition in South Australia.

“How can we monitor the energy consumption levels of Renewable Energy?”

 

Renewable Energy is one of the fastest growing sectors of all time. However, because of its distributed nature, monitoring the energy consumption levels without an interface can be a great difficulty. Because of this, engineers have developed Onsite Renewable Energy Monitoring to analyze distributed resources in real time!

“How can we have multiple inputs control a single output?”

 

Circuit technology can be found in all aspects of our lives nowadays, whether it be in the smartphones we carry or the airplanes that carry us. However, one problem that we keep on running into is how to take logic from multiple inputs and have it govern a single output. Well, if we can apply our engineering mindsets, then we can find that combining everything with sequential logic, we can invent a machine known as a multiplexer which can accomplish our goal. An example schematic of a multiplexer can be seen in the image above.

“What is the most efficient solar tracker?”

 

PWM Solar Charge Controllers are definitely a step up from On/Off Solar Controllers. However, they’re definitely not the most efficient models. MPPT Controllers (Maximum Power Point) can maximize the output by changing the current and voltage delivered while doing the best to keep power constant. Because of this, they are the most highly valued systems on the market.

“What is the current industry standard solar controller?”

 

On/Off Solar Controllers are great for simple and inexpensive projects. But sometimes we need to have more efficient solar control. One way to accomplish this is to vary the power of the battery depending on how full the battery is. The more empty a battery is, the more power it will receive, and the opposite when it is near full. This setup is known as a PWM Solar Controller and is the Greentech industry standard.
