Hullo again... here goes

I am fascinated by the emotive language that appears whenever this topic comes
up.

Back in 1996 I wanted to get to the bottom of the issue and set up my own
democracy rack. I installed the leading brands available at the time, namely
Siemens, Solarex, BP and Canon/Unisolar, and watched them perform for 12 months.
I particularly concentrated on the daily amp/hour yield.

At the time I had no loyalty to a particular brand.

I set-up the jig with automatic voltage cycling to simulate real world
conditions as you would find in any battery based RE system.

For my trouble I received threatening phone calls from agents, such a test is
not to be done I was told.

The results I got were consistent with other similar tests in other parts of the
world.

Anyone can Email me personally for a summary.

I note that the tech. who did the Real Goods solar shoot-out in Sept. '98 at
Ukiah California had his hand smacked similarly but I managed to get a copy
before the report became hard to get.

It is a long time now since we have an update from the Homepower democracy rack,
this would help the situation especially if it were possible to take Amp/hour
yield readings as well as power output. I understand that Homepower have a lot
to do who else would like this to be a priority ??
