Has anyone found roof anchors that are designed to span the ridge cap on
existing composition shingle roofs? We have a number of different types of
anchors that we attach on the north side of the roof with screws into the
truss but that invariably leaves the issues that result from running a rope
Quick Release PV System
I just had a set of plans rejected by the City of Chula Vista, CA, because the
integrated Tile product that we use did not have a Quick Release System for
the array, so that the Fire Department could remove the array in the event of a
fire.
Has anyone ever heard of
It seems to me that allowing an expensive array to be quickly and easily
removed from a roof is a Very Bad Thing- I'd guess that the customer's
insurance company would have an issue with this too. Will they also
require that heat pumps have wheels and flexible pipes, so that they can
be moved
Hi Andrew,
Good topic! We typically use a ridge anchor like this:

On existing comp roofs one option is to gently peel the top shingle off and
then fasten the anchor down. After work is complete you can remove the
anchor (often times with

This might be what you're looking for since it's designed to be permanently

Wrenches,
While we're on the subject of CBI breakers does anyone know a sure
way to distinguish between the AC and DC versions? Depending on the
order we get our stock from both Outback (or Outback vendors) as well
as directly from Midnite. It's obvious with Midnite's 150 VDC MNEPV
Wrenches,
Below is an excerpt of an announcement about New Mexico's largest IOU
developing a utility-owned PV roofs program. They will contract the
installations but own the systems. The details aren't yet out; the
announcement is about an upcoming meeting to gather feedback.

Andrew,
This is my favorite:

It has a butyl strip under the steel strap which helps seal the nail
penetrations, and if you install it properly, all of the penetrations will
end up underneath the ridge shingles. When you're done, you can just leave
it for
SOLYNDRA --what type of glass is SOLYNDRA made of ? It is illegal to use

Wrenches i have a unique problem. I have a 2.5kw grid tied system
installed using a Xantrex GT inverter I also have the wired monitor that
uses the standard Cat5 cable. The problem is the Remote meter dumps its
data randomly sometimes once a month and sometimes it will go 3 months.

Hi Brian,
Now you're asking the right questions.
Perhaps someone from the building planning department in Irvine was layed
off and they got a job in Chula Vista.
There are a number of a$$-backward municipalities down that way. Dunno what
their real agenda is, but stuff like Provide UL
Power factor on DC? As far as I know, power factor / vars is an AC phenomena
where current and voltage are out of phase.

HI The power factor is set by the inverter. The modules are unity as there are
DC. but the inverter is very close to unity. The couple of times I tried to
measure power factor I got Unity. But I would think the load may affect the
inverter power factor.

Chula Vista has been difficult on a number of fronts for the past few years.
I'm not sure what is behind it. This is a reference from an old Los Angeles
Fire Department regulation. It was invented by a person at LA who still
thinks it's a good idea. I don't doubt that it could not be developed. My

What if every 4 rows or so, you left extra space to hack into the
