Embedded Computers and Solar

The Raspberry Pi a small, inexpensive, full-featured computer  

Lately, I've been going down the rabbit hole of learning about embedded computers and it got me thinking about how these cool devices might benefit solar energy systems.  Embedded computers are essentially modern desktop computing power in a much smaller size (i.e. deck of cards) and priced in such a way that they could be almost be viewed as disposable (>$25).

My first thought was that embedded computers might control solar systems or aid with the reporting of data. Any decent residential inverter does this pretty well already with a variety of data input and outputs pre-loaded.  On the solar thermal side of things, energy metering packages could be built for well under $100 in parts which could reduce the cost of these types of add-ons for a small residential system so there could be a solid application there competing with products like the Apollo package.

A solar toaster?  Maybe not, but solar powered entertainment equipment is likely

Turning this computer-to-solar relationship on its head, solar PV might actually help make these little computers even more autonomous by cutting their power cord tether and keeping them in action almost continuously.  Think of little Roomba-like robots at home that don't need a charging station anymore.  Embedded computers don't only relate to robots but have all sorts of other applications like in home automation & entertainment systems.  PV built into these devices would not add any new load to the existing building.  Even better, these new devices could interact with energy management systems and even provide additional power back to the house when the devices aren't in use.  Quality of life continues to improve while our buildings continue to get smarter.

Whole building PV versus task-oriented, embedded solar?  Both have their applications and both versions of solar may end up working along each other very soon.

Change Happens Faster Than You Think

Maybe not the father of solar energy but a tremendously influential and critical thinker .

“There are decades where nothing happens; and there are weeks where decades happen.”

- Vladimir Ilyich Lenin

I came across this quote today while watching a TED talk about the speed of change we are now seeing in human biology from both intentional and unintentional sources.  A case can be made that we may be an entirely different species of animal than we are today in only a few generations.  It's a fascinating lecture about evolutionary biology, and it sparked a connection in my brain to the state of solar today.

Solar energy development appears to be following this dictum.  Massive changes are happening in the business almost on a daily basis.  The speed of change is so fast that it makes it difficult to comprehend it or make accurate predictions or plans for the future.  In all probability, we will have an entirely new energy infrastructure in less than a couple of decades.  How this might happen or what shape this new energy system will take is still far from certain.

In the face of uncertainty, don't lose hope--focus on the basics. Work to continually improve your general health and intellect.  Study your industry and market.  Engage with customers and suppliers.  Think about the major issues you face on a daily basis and try new things.  Solar energy will win because it's the energy source that got us to where we are today. It's now the time for us to become more a little more sophisticated about how we harness it and much more intentional about how we apply it.
