“How have residential batteries overtaken utility deployment?”

 

Breaking news! In the last quarter, residential batteries have overtaken utility-scale deployment. This comes as a result of the drastically decreasing price for in-unit batteries. Whatever this means for the future of battery storage is quite exciting.

“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.

“What’s the whole new thing about California, solar panels, and homes?”

 

Something historic just happened. In a daring first for the U.S, the California Energy Commission has just reached a ruling requiring all new homes and low-rise apartment buildings built in California to have solar panels installed. This is all done in part to lower the state’s greenhouse gas emissions 40 percent below 1990 levels by 2030. Although hailed by many in the renewable energy industry, skeptics like to point out that this could be poised to raise the cost of construction even more so, exacerbating the state’s already out of control housing crisis even further. However, the reduced electricity bills from these solar panels have been shown to actually recuperate their cost and even payback money over a 30 year lifetime. However this plays out, it will have drastic effects on the state’s electricity portfolio and could cause other areas to follow suit.

“How do we quantify the difference between renewable energy generated and energy demand?”

 

Renewable energy is now able to generate vasts sums of power in many parts of the world. However, it currently is not able to provide all of the power consumed by many parties. Because of this, renewable energy experts have called this difference to be the Net Load on the system. The Net Load tends to be lower at noon due to the availability of the sun (resulting in the infamous duck curve). California’s net load can be seen on this website.

“Will big utilities face a compromised future from distributed energy resources?”

 

Ever since the dawn of the grid utility companies have reigned supreme. But with the advent of distributed energy resources, this all might change. Now that many individuals are achieving grid defection, they no longer have any use for a utility. If the cost of battery storage collapses and energy efficiency has a paradigm shift, this could spell massive disruption for these traditional companies. They might even have to watch out for their survival.
