Return on DoE Investment
Greg M. Jung   12/28/2012 9:35:04 PM

For the amount of money invested into this technology, it seems that the expected deliverables from this company will be:

"reducing the electricity requirement of the system by 20 percent while increasing the output of the panels by up to 15 percent"

It would be good to see the DoE follow up  after 6-12 months to make sure that these deliverables are on-track and that this investment into this solar technology will pay off and come to fruition.

That's a good point about the expected deliverables.  But, I think ROI will take more than 6-12 months.  The US gov't doesn't historically get a quick return on investment.  It would be interesting to look at how the development not only helps Qbotix but all solar companies.

More details from Qbotix on youtube:  http://www.youtube.com/watch?v=hKiDeEL0leY

Will a million dollars go very far though?

I agree I would like to see a follow up later.  However, I have never really known the government to follow up and make sure our tax dollars were spent wisely.

The government (politicians specifically) do have a measure of how wisely money is spent. It is called re-election. We keep re-electing the same crooks and expect them to spend our tax money wisely???

I am always a skeptic, but if this company can build and prove working prototypes then they are worthy of a little research grant money. But the market should determine the cost effectiveness of their technology and not government mandates (or political donations).

Gee, I hate to  throw a cloud over this BUT solar trackers have been available for YEARS. Check out an issue of HOME POWER magazine and you'll see a number of trackers FOR SALE NOW!

I wonder which politicians son-in-law this company belongs to?

Thanks for your comment, Greg. I agree, there should be some sort of barometer to ensure QBotix and other companies and organizations that have received these grants deliver on what they promise to advance alternative forms of energy.

Finding a Balance

Very interesting - it must be hard to find the balance between energy used tracking the sun and the optimum tracking interval for energy gained tracking the sun.

I suppose it would also depend on the amount of cloud cover, the time of year, the amount of daylight available.  Several different complex variables for a complex system.

Good points, jmiller - there are several variables to consider. Not only could the system optimize tracking with energy efficiency, I could also envision an automated protective cover for extreme weather protection (hail) and a system that could remove debris accumulation - perhaps some type of blower or rake - I wonder if that is on those systems...

Yep,  they are going to make Solar competetive all right.  Wasting money on stuff like this, and then piling taxes on everything else until parity is acheived.

Cost Versus Value

With the latest solar article I did for Design News, it is absolutely clear from the leading suppliers I interviewed that a key design goal is driving cost out of these systems.  In many cases given the size of typical larger installations, tracking systems are being applied to a row of panels to drive down costs. Even off-the-shelf PLCs (which should offer a low cost control) are often viewed as too expensive compared to custom controls that offer a specific solution (even if it's not true given development and engineering costs).  It's very hard to understand how this robotic approach has much of a chance to further enhance system performance compared to existing tracking solutions.

The company recently was awarded another $12-million in funding, this time from European energy giants EON and Iberdrola for implementation of the QBotix system in Spain, Latin America and the UK. My question is what did they do with the original funding?
