How To Create The Best Technical Specification Of Solar Street Lighting Systems;6 Tips

There are very many different types of standards that a product, service, designs, or material need to follow.  In the same case, there are a couple of ways manufacturers and consumers can communicate when describing a product, and the technical specification of solar street lighting is one of them.

A technical specification document lists several requirements that must be met for a product to be complete and function as required. This type of product description is a requirement in the assembly and use of a product that is being advertised. Often, a technical specification is used by a developer, customer,  or client for reference. It can also help you understand the configuration of the product, the hardware, and the software.

Technical specification of solar street lighting

Only the best technical specification of solar street lighting systems communicates to the consumer and makes them want to buy solar street light.  A solar street lighting system technical specification should include technical/physical details and then followed by the functional and performance specifications. As you create this document, it is essential also to indicate the purpose and capacities.

Here is how to create one:

Physical Details or Definition

For technical specifications, you need to describe what you see when the solar street light is completely assembled. You will need to mention the various components that are visible and the role they play in the system. You will have to visualize the design of the solar street light and how different elements are mounted. You may also include where the product will be used such as the suitable industry or area of application.

This is a general description of the street light, including how the various components are housed. These components should follow with a brief explanation of the functions they provide in the system.

At this point, you will have to describe how the street light is powered. This means you will have to describe the way electricity flows from the PV module until it reaches the luminaires. Most manufacturers prefer to use diagrams and visual aids.

Technical Details:

In this section, you will have to provide more information about the various components you mentioned in the physical details section.

  1. PV Module

Here, you will need to mention the type of PV module, the power output, the open-circuit voltage, its efficiency, number of cells, tilt angle (if required),  output peak watt capacity, coatings, and the standards the component needs to meet.

  1. Battery

Here you will need to mention the battery make and type, the capacity, charge current, the permitted rate of discharge, power supply specs, mounting position, back-up, housing specifications, and the standard requirements met by the component. You may also give a description of how protection is achieved. It may also be necessary to indicate the manufacture date.

  1. Light Source

In terms of the light source, you should mention the type of bulb used, the system wattage, the efficiency at system and bulb levels, bulb life, correlated color temperature (CCT), dimming capability, and other standards met by the product.  You may also include the luminaire housing, mounting height, and how protection is achieved.

  1. Electronics

This part of the document accommodates all electrical aspects of solar street lighting. There is a need to mention the electronic efficiency, the load current to be used  (DC or AC), the type of installation, the wiring required, the control mechanism or technology used, and other standards met by the various electronic product.

You may also give an account of equipment such as the Maximum Power Point Tracking (MPPT) battery controllers, circuit breakers, chargers and Inverters; information required may include the type, power supply specs,  frequency, output wave, cooling method, efficiency, protection, and operating conditions.

This section may also include a brief description of the earth protection with great detail of the components used and the conditions required.

  1. Mechanical components

Mechanical components may include and not limited to poles, cables, mounting and housing structures, fasteners, and accessories. The material used in the making of these components should be mentioned, and the corrosive resistance and the weatherproof nature should be indicated.

For the pole, you may provide details such as the type of material used, the height, coating, and its wind speed resistance. As for the cables, you should try and describe the material used, the type of insulation, and dimensions.

Functional And Performance Specifications:

The functional and performance specification deals with what the solar street lighting system does and what it can deliver. In functional specification specifies the functions that the solar street lighting system must perform, while the performance specifications specify the operational requirements or desired outcomes from the product.

Here you may include the environmental conditions that you must take into account for the design and operation of the product. These include conditions such as the ambient temperature, rainfall, relative humidity, seismic conditions, and climatic area classification. Do not forget to include the system’s duty cycles and protection.

The quality and warranty:

In this section, you will have to mention the quality standards that have been met or should be achieved by the component. Here, you are required to provide the quality control measures that you will use to ensure that the product is according to the client’s specifications. It is also essential to define the QA/QC, inspection, and testing activities.

The next thing that should follow is the warranty of the PV module, Battery, luminaire, Inverter, and any component that requires one.

International Codes and Standards:

In this part of the document, you will have to provide the full number of standards and codes used in the design of the product.

Packing And Storage

This marks the final process of the product development ready for storage or shipping. You will have to cover transport and storage specifications. Other information includes the protected against corrosion and the storage period. You may also include the requirements for the preservation of the product (equipment and materials)  for long term storage after delivery.

 Technical Specification Of Solar Street Lighting: Conclusion

It is expected of you to write the technical specification in the language of the target audience.  The technical specification of solar street lighting can be in table form or in detailed paragraphs.  Therefore, you will have to disassemble the solar street lighting systems into the various components and gather enough information on these products.
