Our goal is to provide our customers with the best equipment, the best installation and the best long term value available on the market today, and we want to do it safely
California—Perfect for Solar Electricity- or at least it was
In order for Solar To be Cost Effective you need: Lots of Sunshine High Electricity Rates Net Metering Interconnection Laws Solar Rights for Consumers (California Civil Code 714) Full Access to the roof for Solar Panels to avoid
shade, vents, chimneys, skylights and upper roof structure shading

The 3’ Rule makes Roof Space much more expensive Solar Installers currently have to deal with Trees, Chimneys, Vents Roof Space is already valuable—Fire Boundaries exacerbate the
issue Sunpower and Sanyo are the highest output but most expensive
panels This will shift almost all solar over to the highest cost panels and
will limit or eliminate most of the polycrystalline panels installed in the US
This will increase the overall cost per watt by at least $2.00 as we shift to smaller systems with the same overhead, and fixed costs
Bad news, we will virtually guarantee that Monocrystalline prices will rise
Firefighters Deserve a Safe Environment
Heritage Solar, Inc. All Rights Reserved
Firefighter Roof Safety is Important Firefighters Should Have 50% of the roof for Egress and Venting without
triggering a Fire Authority Review Emergency Egress—Suitable pathways for Access and Egress Smoke Ventilation
Suitable location for Standard 4’x 4’ hole Suitable location based on wind direction Suitable location based on Roofing Material—Most of Orange County is Concrete Tile
Most Training videos and actual fire videos indicate that firefighters go up the middle of the roof, remove the tile, use 5 cuts to remove surface plywood, and then use a tool to break through the ceiling drywall.
After venting is accomplished, firefighters egress down the middle of the roof to the ladder, avoiding unprotected edges of the roof.
Our Employees Deserve a Safe Environment Too

The 3’ Rule Shifts Risk
Heritage Solar, Inc. All Rights Reserved
The 3’ Rule at the peak shifts Low Risk Low Probability from Firefighters to High Risk High Probability for Solar Installers
Solar Installers have a much Higher Probability that we will be on the roof. There is a very low probability that a Fire Fighter will be on the roof and need the 3’ easement all
the way around the solar array Solar Installers have a much Higher Fatality Rate Solar Installers are on the Edge of the Roof for Extended periods
The 3’ boundary at the ridge forces most solar arrays to the very bottom edge To install the bottom stanchions, rails and panels:
• Hook up to a rope• Carefully walk to the very bottom
edge carrying tools and hardware• Sit down on bottom edge of roof• Remove Concrete tile in a downward
direction• With a brush, remove debris• Drill a pilot hole
• Apply adhesive to hardware• Lag bolt hardware to rafters• Drill hole in concrete tile• Replace concrete tile and install final
hardware• Repeat multiple times to get all of the
stanchions in.• Install Rails and Grounds• Install Solar Panels

In Summary, Since 1982 or so, there have been 7 reported fire incidents in the United States involving solar either directly or indirectly
The End of Cheap Oil
Hubbert’s Peak calculations predict worldwide oil production will start to go down—2005
Globalization has increased the number of available consumers by 3 billion
China and India are expanding rapidly and their demand for oil is tremendous

Increasing Electric Grid Loads Cars will become electric or hybrid
electric Plug in Cars will significantly increase the
load on an already strained electric grid Electric prices in California will skyrocket Electric Rationing may occur In order to maintain lifestyle, individuals
will buy solar for their homes

How Can California Improve No Fire Review or boundaries if Solar is
<40% of Entire Roof No Ridge Boundary if roof is 4:12 or less 1 Foot Ridge Boundary if roof is >4:12
for Firefigher ladders with hooks No Egress Boundaries if Solar <40% of
Entire Roof (1) 3’ Boundary if Solar is >40% of Entire
Roof

Conclusion
The Cal Solar Fire Guidelines (3’ rule) are a colossal unwitting error in judgment that will cost the United States, and California in particular, Billions of Dollars in money that could be saved by consumers and reinvested in the economy without (arguably) improving Firefighter Safety.
The Guidelines will have a devastating affect on the Solar Sector and will cause a dramatic reduction in Potential Jobs in the Solar Business.
The Original Solar Representatives who commented on the Guidelines in the first 6 months of meetings were unqualified for the task, did not genuinely represent the needs of the Solar Industry and suffered from a lack of imagination and vision. They did not understand the ramifications of the 3’ rule or that it would be enforced rigidly
The Guidelines neglected to balance installer safety, consumer cost savings, and the greater good to the community, the environment and the economy
The Guidelines neglected to balance personal freedom of individuals to install solar on their homes
