California Contractors License #833782 C-7 C61/D31 C46
C46 - Solar Contractor A solar contractor installs, modifies, maintains, and repairs active solar energy systems. An active solar energy system consists of components which are thermally isolated from the living space for collection of solar energy and transfer of thermal energy to provide electricity and/or heating and cooling of air or water. Active solar energy systems include, but are not limited to, forced air systems, forced circulation water systems, thermosiphon systems, integral collector/storage systems, radiant systems, evaporative cooling systems with collectors, regenerative rockbed cooling systems, photovoltaic cells, and solar assisted absorption cooling systems.
D31 - Pole Installation and Maintenance A pole installation and maintenance contractor installs wood or precast poles to support the wiring or cable that is installed by others ...
C-7 - Low Voltage Systems Contractor A communication and low voltage contractor installs, services and maintains all types of communication and low voltage systems which are energy limited and do not exceed 91 volts. These systems include, but are not limited to telephone systems, sound systems, cable television systems, closed-circuit video systems, satellite dish antennas, instrumentation and temperature controls, and low voltage landscape lighting.
MARTIN HERZFELD is a qualified and authorized
renewable energy dealer, integrator, independent contractor and
consultant.
After the solar site shading and soil analysis, a ground-mounted
photovoltaic (PV) system may be planned, designed, implemented, and
supported. System integration along with contracted information
technology solutions for monitoring to assist or train with select
installations as an option - expert and industry leader, in business since 2001.
'Overall project manager focused to the project and will assure
successful implementation and overall project completion including the
necessary documentation. The ability for complete documentation,
tracking, financial status of projects. Presentations easy to track and
are in a concise and understandable format. Dedication and successful
completion of goals and objectives. Ability to understand new
technology and apply it from a business perspective. Capital budgeting
process and financial projections for projects. Excellent ability to
coach and teach technical matters. Customer oriented and developed
reputation with clients and vendors. Highly intelligent and able to
apply that gift to the production of creative innovated work.'
The ZI 0310101B was planned, designed, implemented and supported with the lowest ambient array temperature design with the higher V(oc) as the correct answer in 2003 for the demonstration system. Yet today, the lowest ambient temperature high V(oc) design remains the preferred methodology and the desired solution with traditional photovoltaic source string inverters - optimal performance methodology with degradation, the inverter efficiency curve, power loss, cost of conductors, temperature, ... as a factor. Not only the efficiency of the cell, but the efficiency of the system. Now, with the choice of both micro-inverters and macro-inverters, a small, medium or larger ground and pole mounted solar electric system would result in various solutions.
