Single Line Diagram


Single-line diagram (SLD) is a simplified notation for representing a power system. It is a form of block diagram graphically depicting the paths for power flow between entities of the system. It is the first step in designing your solar project, allowing you to become thoroughly familiar with the electrical system layout and design in your facility.

We provides:





Cable sizing:

The proper sizing of an electrical cable is important to ensure that the cable can:

Current carrying capacity of the cable and its deration. Provide the load with a suitable voltage and avoid excessive voltage drops. Withstand the worst short circuit currents flowing through the cable.

Cable Schedule:

A cable schedule is a table of information about cable lengths for a particular installation. A building floor plan would often be associated with the cable schedule and the type of information shown could include:

  • Length
  • Type and size
  • Colour
  • Route
  • Conduit detail 

We provides the following details in cable layout:

  • Cable sizes
  • DC, AC, and cable route



An earthing system or grounding system is circuitry which connects parts of the electric circuit with the ground, thus creating an alternative path for the flow of fault/excessive currents safely into the ground in the presence of minimal resistance or impedance. The primary purpose of earthing is to reduce the risk of serious electric shock from current leaking intouninsulated metal parts of an appliance, power tool, or other electrical devices.

In earthing we will cover:

Earthing Calculations: Earthing Strip size and length calculation, Type of electrods

Earthing pit details: No. pf pits required, chamber details

Combiner/Junction Box


Combiner Boxes can be AC or DC or both depending on the project requirement.

DC Combiner Box:

DC combiner box is a device that combines the output of multiple strings of PV modules for connection to the inverter. 

AC Combiner Box:

AC combiner box is a device that combines the output of multiple Inverters and gives the single output. 

We design Combiner boxes which also provides protection and performance monitoring for photovoltaic systems.

Weather Monitoring & SCADA


A weather monitoring station is a facility, with instruments and equipment for measuring atmospheric conditions to provide information for climate. The measurements taken include temperature, irradiation, humidity, wind speed, wind direction, and precipitation amounts.


(Supervisory control and data acquisition) is a system operating with coded signals over communication channels so as to provide control of remote equipment. 

We provide the comprehensive communcation layout to insure the proper data acquisition.

Module Mounting Structure


Solar Mounting over RCC Slab

Solar Modules are mounted using table structure with foundation fixed with the existing slab. The structure will be fabricated to the required tilt arrangement and assembled in the site. Module Mounting structure are designed as such to withstand the self –weight of modules and wind pressure which act on the modules.

Following are required data to design the module mounting structure over roof slab

  1. Module specs which is required to get details like module dimensions, weight of modules etc.
  2. Basic details of site like location, building height, surrounding environment (i.e.)  wind obstruction are more or very open terrain this details are required to calculate the wind pressure on the module mounting structure.

Before loading the module mounting structure over the existing roof slab, we will ensure that the existing roof slab is capable of withstanding the additional loads. To ensure the stability of the existing slab following details are required.

  1. Thickness of roof slab.
  2. Whether the roof slab is designed by considering the factored loads.
  3. Details of water proofing provided on the roof slab.     

Solar Mounting over Roof Sheet:

Solar panels are mounted over the roof sheet by using the special types of clamps to hold the module with roof sheet. The following are types of roof clamps available.

  1.  Trapeze Bridge
  2. Protea Bracket
  3. Rib Bracket
  4. S-5-Q, S-5-Z
  5. CorruBracket 100T, CorruBracket.

The following roof profiles are most commonly used in construction of industrial sheds & for covering building roofs.

  1. Trapezoidal Roof Profile.
  2. Corrugated Roof Profile.
  3. Kalzip Roof Profile.

Roof sheet for solar mounting should be as such it should withstand the self-weight of solar panels and wind pressure on the roof sheet.

Following are required data to mount the solar modules over the roof sheet.

  1. Technical specification of roof sheet with the following details like material & sectional property, roof profile longitudinal, traverse flute arrangement, thickness of roof sheet, supporting span and loading details.
  2.  Basic details of site like location, building height, surrounding environment (i.e.)  wind obstruction are more or very open terrain this details are required to calculate the wind pressure on the roof sheet.
  3. Existing roof slope details (i.e.) mono slope roof, double side pitched and curvature roof.
  4. Module specs which is required to get details like module dimensions, weight of modules etc.

Foundation Drawing


MMS Foundation is designed as such to withstand the uplift caused by wind. In general, foundation of module mounting structure will be in form of square or circular pedestal with required mounting arrangement for structure (i.e.) Base plate with anchor bolt or any suitable mounting base.

In case of uplift is higher, the foundation casted with existing roof with special adhesive. So that to withstand the uplift.

Equipment’s Foundation:

The foundation fixing arrangement is required for the following equipment’s

  1. Inverter ,ACDB & DCPB
  2. Lightning Arrestor
  3. Weather Monitoring station.

Foundation will be design to withstand the weight of the equipment and equipment is mounted on foundation with suitable anchoring arrangement.

To design the foundation of equipment’s following details are required:

  1. Dimensional details of equipment is required so that suitable foundation base can be provided.
  2. Equipment mounting hole details.
  3. Weight of equipment.
