     As I said the GT inverter already has shut down circuits and can't by code.   There isn't a way for it to hurt a lineman.  Please show in actual gridtie equipment how that can happen?   And as I said even if it did it would short out.  Basic physics.

         I live in Fl and would have went into production of RE but only utilities can sell electricity here by our gov bought and paid for.  Not only that but the ratepayers have to pay $.03/kw for 10 yrs to buy Progress and FPL 2 new nukes each for free!  So I'm doing EV's instead.

Jim, that's incredible. Although back in the 70s and 80s we experienced similar resistance, to put it mildly, from utilities here in California about buy-back, it's now an established practice.

It took a really long time for the polycrystalline wafer-based PV market to achieve the solar power holy grail of volumes high enough to drive down cost-per-watt. But then it seems like a very short time elapsed before it went to oversupply. This isn't atypical of semiconductor-based markets, but it is disappointing.

Grid parity is certainly a worthy goal, but questions remain about the real cost of building back-up systems to prevent blackouts when the sun's not shining. A recent editorial in The Wall Street Journal stated that renewables need "up to 90% of their capacity back up to revent blackouts." As long as we pay twice (or at least an extra 90%) for our power generation, solar will be a niche.

Today, no matter where in the world the device is located, it can call home and ask for the latest-and-greatest firmware with bug fixes and feature updates.
A decade from now, firmware development may be nothing more than software integration, grabbing vendor and third-party components, and meshing their APIs together to form a final system.
Design, simulation, manufacturability, and prototyping: All of these phases are being pushed forward and progressively by underlying technologies.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
