TMG’s solar power consulting team has designed MORE THAN FOUR THOUSAND
solar installations, with individual designs incorporating a few dozen modules
to hundreds of modules. Being in India, our rates can be up to 40% less
than what you are currently paying.
TMG has a large team dedicated to solar power system design and produces several
hundred designs a month. Almost all these designs are turned around overnight.
The team comprises managers, project leaders and drafters.
The project leaders and drafters work only on solar power system design projects full-time.
Our managers have each supervised thousands of designs during their
tenure at TMG.
Above: Solar Power Consulting Team Structure
TMG’s solar power consulting team is well-versed in the nuances of solar power system design,
The optimal roof faces for panel placement (depending
on the geographic location of the target site)
Norms for the spacing between arrays
Conventions for clearance between arrays and roof
Rules for combining array outputs before connecting
them to inverters
The particular characteristics and data of the leading
inverters and solar modules
The connection methods for combiner boxes, ac disconnects
and the utility meter
Consequently your technical personnel will not have to spend time training
us and can look forward to comprehensive designs from the inception of the
contractual arrangement with us.
Like any conscientious company practicing solar power system design, TMG constantly
tries to achieve a zero defect rate in its output. Over the course of more
than four thousand projects, we have evolved an effective quality assurance
system that has reduced defects to near-zero levels. The system comprises
the following methods:
The work of each drafter is checked 100% by his project
The same files are then checked 25% by the manager
who oversees the project leader
Project leaders and drafters are counseled with directions
to avoid any errors that were found
Executive management discusses quality improvement
for each project during its weekly review meeting
We schedule a weekly videoconference with you to
ask if there were any errors in our solar designs that we were not aware
TMG's Solar Power System Design Procedure
TMG’s solar power consulting team has over the long-term evolved an efficient
and streamlined procedure for developing designs.
Step One: Obtain Inputs
In this step, TMG requests the following from you:
A photograph or sketch of the target to roof (plan
view) with protuberances such as pipes and vents visible
The scale factor of the above image or dimension
Your preferred make and model number of solar modules
The power you expect the system to generate
Data on rafter width and spacing
Your preferred locations for electrical hardware
such as the sunrun meter, the load center and the inverters.

Step Two: Position Arrays
TMG's team positions the solar PV arrays using the following
Identify the optimal roof slopes (if rooftop installation)
and tilt angles for solar energy capture based on the geographic location
of your site
Define the size of each array based on standard industry
Locate the arrays on the target surfaces by avoiding
protuberances, following clearance guidelines and avoiding shadows from
Plot the positions of the attachment points and define
the mounts that have to be used based on the characteristics of the
roof or mounting surface.

Step Three: Design Electricals
TMG's solar power consulting team designs all interconnections and specifies electrical hardware
using the following methods:
Define stringing cables based on anticipated current
Interconnect arrays with the appropriate type of
cable and junction boxes
Define the electrical connections to the electrical
support components, including the inverter, solar power meter and disconnect

Step Four: Package the Design
TMG processes the design information thus created as follows:
We create a cover sheet using your template and layout
preferences. The cover sheet typically includes a satellite view of
the target site, a street map to the site, information on the power
generated by the solar installation as well as the model, make and quantity
of the proposed modules.
We create a layout sheet to scale showing the module
layout with attachment points
We create a single-line electrical diagram detailing
electrical connections and specifying associated switchgear
We save each of the above drawings in PDF format,
put them in the folder and create a zip file of the folder
We hope the above information has convinced you we are expert solar power system engineers.
That said, our expertise is available to you at unbelievably low rates.
