Wrenches,
I'm looking for commercially produced PV solar powered light systems, the type
that would be used to illuminate a parking lot. I would appreciate any
recommendations or warnings.

Friends:
I am designing an installation on a roof built with engineered rafters.
These are wood I-beams with 2X4s (or smaller) on flat, dadoed to accept an
OSB flange in between. On top is sheeting and then sheet metal. I have
never attached to engineered rafters
I checked on DPW easy
We just did one, and I used some fairly
short Timberlok type lags (thinner and stronger) I wasn't super
excited about only having an inch of wood to grab, but the edge
wood is stronger and denser than regular 2x material it seemed.
I predrilled the holes, and

When you first posted I forwarded your request to our warehouse
manager, who's quite experienced. He didn't receive any of the
responses from other Wrenches, but sent this to me this morning:
Inspect it immediately for obvious signs of

For what it's worth, you may want to check with the rafter mfgr and/or Eng as
it is possible they will not allow holes being drilled into them and you could
open yourself up to liability issues.
I have a structural eng who is insisting I squeeze a construction adhesive

Hey folks,
I'm in the middle of re-commissioning properly(megger, curve tracer, etc.) a
45 kw system that I installed using BP SX170B panels in the Spring of 2006.
I have found 5 strings so far with 0 Voc, and 2 strings with a good Voc but
0 current when the inverter is operating. I have
And watch out for theft...I once had ordered -12- two-volt cells from by
battery dealer but only -11- were on the pallet. They were delivered to a
neighbor business who has a forklift and signs for me. No damage was noticed
but somewhere along the way a battery was removed(most likely to sell for

My last warranty contact was Tracy Cox at 301-698-4307, cox...@bp.com, but
I'm not sure how current that information is. I've had regular BP/Solarex
warranty problems over the years (since 1990 or so), and it's seemed like
they were generally slow to respond before they stepped up to the

Wrenches - I am working with Lee Bristol and Ray Walters on 20 off-grid PV
systems in Tanzania at various types of remote health care facilities.
There will be 3 system offerings: 2, 4, and 6 kW, all 230V, 50Hz. We are
currently considering the following issues and would appreciate input:

Thanks guys. Obviously not a simple thing in terms of BP making it right to
the satisfaction of all parties. Any substitute mod will require matching
properly to unalterable roof footprint, existing rail layout, and existing
inverters, requiring a new design, PE stamp, permitting, inspection, to
I guess I never followed up. The warranty claim process was a success; just had
to take lots of unnecessary pictures. BP paid out a check to replace all the
modules even though only half of them failed. Guess they have a crystal ball.
Warning: They will not reimburse for labor.
Contact Lini:
The array size and quantity of all the modules?. Thanks.
