looks like it took out a Fire Emitting Transistor in the power supply section of the board...

Good times, seeing what happens when you let out the Magic Smoke.

The folks at http://fieldlines.com/ have been doing this for years. The bigger problems are the sealing of the cells and the fact that since these are most likely rejects the cells might nog give their rated power.

The article summary is dead wrong in suggesting that this is somehow proof that solar cells could be produced cheaper, these cells have probably been hijacked on the way to the recycler.

'making' a solar panel in your garage does not start off with buying solar cells and hooking them up, it starts with sand.

A generator is not the only answer. by DamonHD · 2008-12-31 10:06 · Score: 1 · on Home Generators (or How DTE Energy Ruined My Holidays)

Everyone seems to be assuming that a fossil-fuel-powered generator is *the* answer and the only questions are "how big?" and "is the widow-maker male plug fine?"...

Goodness.

Try (say) solar and or wind and several days worth of lead-acid batteries with a suitable inverter such as Sunny Island or Sunny Backup or the Outback or Xantrex equivalents, which won't kill you with carbon monoxide and bad wiring, you don't have to refuel, and which doesn't destroy the planet in passing...

Oh, and you might get a subsidy or a tax-break for installing such a renewable-energy system too.
And you can export excess to the grid and get paid for it when the grid isn't out...

Those widow-maker setups have that name for a reason, BTW.

in how you use the heat. Focus the suns rays on a pipe with water running through it and then what? I built a solar air heater using popcans for $80 and use it during the summer to heat water and during the winter it heats and recirculates air in the house. Here is a solar heater someone else built (same thing here) http://www.fieldlines.com/story/2007/8/20/124818/249

powerline repairs by falconwolf · 2008-07-21 21:04 · Score: 1 · on Switching To Solar Power – One Month Later

What happens when the lineman makes the final connection and closes the gap? Under a normal situation where the power flows only one way, nothing, as the power's been cut off at the transformer upline. Once he's done and has moved to a safe distance, the power company turns the transformer back on and life continues. However, if my excess power is being fed back in to the grid, SURPRISE! The line is live the instant the final connection is made. The lineman gets a nasty (and likely fatal) shock.

This is why inverters have low voltage cutoffs. UL and IEEE have rules and standards to prevent inverters from islanding and harming repairmen. Many systems that intertie into the power grid require these cutoffs so that when the powerline drops to zero the inverter won't feed power to the lines. This has been worked out quite well already.

IEEE's Xplore has an article on this, "Virtual inductor-based islanding detection method for grid-connected power inverter of distributed power generation system" [only a summary].
