“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 nations acquire nuclear weapons?”

 

Although not talked about much anymore, nuclear weapons are still a serious part of international agreements. Only a select number of countries are allowed to possess these weapons of mass destruction (France, the United States, the United Kingdom, the People’s Republic of China, and the Russian Federation). If a nation outside of these signatures obtains Nuclear Weapons, then Nuclear Proliferation is said to have occurred.

“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.

“What is the simplest type of Solar Controller?”

 

Solar Controllers come in all different types of varieties. But if we are strapped on finances, what is the simplest one that we can make? Well, wouldn’t it be a solar controller that simply turned on when there was sunlight and the battery was not full and off when not? This is the basics behind On/Off Solar Controllers, which are commonly used for inexpensive setups.

“How can we keep batteries from being overcharged by solar panels?”

 

Solar Plus Storage Systems are a revolution in the renewable energy industry. Their ability to not only capture but store energy from the sun allows for true grid integration. However, often times there is a voltage mismatch between the solar panels and the batteries. If left unchecked, then the batteries can sustain great damage. But how can we use our engineering mindsets to solve this? Well, what if we were to simply put in a form of control to regulate the incoming and outgoing voltage and current? This is the fundamental principle behind Solar Charge Controllers, almost a must-have for Solar Plus Storage Systems.
