St Francis Catholic College PV System

Scope of Works
To Design, Supply and Install a Grid Connected PV system at St Francis Catholic College Edmundson Park as part of the construction of the school new Technical and Applied Science Building.
The design of the system was to be for a 60kW system, with power generated via LG panels which were to be installed with an orientation to maximise the systems overall output.

Job Description
The system installed for the project comprised of 182 x LG 330w panels, 2 x SMA 25kW inverters which had an AC supply from our custom PV Distribution Board which incorporated the systems Grid Protection Relay.
To maximise the systems output the panel layout was dependant of the physical design and the layout of services on the new buildings rooftop.
The design of the panels was finalised with all 182 panels facing directly North with a tilt of 15 degrees, each row of panels was installed with the required clearance of the buildings skylights to eliminate any possible shading issues caused by the mounted panels on tilt.
The system once completed and fully functional was connected to the Grid with a import/export meter upgrade at the schools existing MSB.

Job Description

This project had quite a few very challenging aspects to it that grew as the project grew. The scope of the project expanded greatly throughout the course of the project and the ongoing design/approval process was one of the most challenging items we needed to resolve.

The final product is an amazing entry/atrium space for the 345 and 363 building entries for the general public. This is an amazing visual space that combines old with new to a 5-star premium level.

As with most jobs all the hard work, blood, sweat and tears are hidden behind a pretty façade. The work undertaken behind the façade to facilitate the finished services is second to none. We had a dedicated team who went above and beyond to provide the client with a fantastic product.

We were constantly designing, re-designing, adjusting our work practices and having to think outside the box and find creative solutions to provide the requested works to the design intent, construction constraints and program deadlines.

There really was no easy part of the project as undertaking major refurbishment works in a trading building puts a lot of constraints on the work process. We mitigated this as much as possible by putting a lot of time and effort into planning and sequencing the works to maximise our output with the least amount of disruption to the client and tenants.

When we came across an issue, we looked at it as many ways as we could and came up with the best solution for the problem. For instance, we made the decision to make all the feature wall and atrium ceiling feature lighting onsite as the approval/program timeline would not allow for the conventional supply and installation process. Having this flexibility is a real asset to our business and clients.

It was a long hard project but a very rewarding with scope additions and challenges that came with it. The Builder FDC was great to work with and their site team also went above and beyond what would normally be expected.

The final outcome is a credit to all who worked on it.

Kerfoot Head Office

Scope of Works:

The project involved the following works to be completed:

  • Preliminary design based around current electricity bills
  • Site inspection of the conditions onsite assisting in completing the design
  • Production of all documentation
  • Purchasing of all equipment and materials
  • Installation of all equipment and materials
  • Energisation, testing & commissioning of the system
  • Client hand over

Job Description:

Kerfoot Pty Ltd was engaged to design and install a suitable solar system to meet the client’s requirements. The system was designed around factors such as the following:

  • Entire site power usage
  • Site power usage during peak irradiance periods
  • Roof capacity
  • Future growth
  • Future battery system

With the above requirements taken into consideration, a 50kW system was designed to meet the needs of the client.
A 50.56kW PV solar system was designed for the site. This design met the entire site load requirements, taking into consideration for the future expansion of the system with a battery storage system to offset the site loads.
The roofing space was adequate to install the entire system, and the wall space provided by the client was sufficient to install the new Solar PV Distribution Board, and inverters.
No modifications were required to the site main switchboard, the only connections required were to the existing distribution board

Stephen Edwards Constructions Office

Scope of works:

To Design, Supply and Install a Solar PV system utilizing the maximum amount of available roof space. A complete mounting system and all associated cabling and electrical protection required so that the installation meets Clean Energy Council guidelines and Australian Standards.

Job Description:

The system is 44.8kW in size, it consists of 160 x 280w Talesun Poly-Crystalline panels. 66 of those panels are mounted on a tilt frame towards North to maximise the output of those panels. The remaining 94 panels are mounted on a flat mounting system sitting flush with the pitch of the roof. One 15kW SMA three phase inverter and one 25kW SMA three phase inverter were used to allow for system flexibility with string configuration. The client requested the premium monitoring option of the system which monitors all power usage aswell as how much the system is producing and offsetting the premises power usage.
Despite a few days being rained out the job was still completed within the expected finish time. The whole project was completed and signed off by Ausgrid defect free once again.

Clemenger

Scope of Works

  • Demolition and make good of existing services
  • New Panduit Communications System including Fibre and Structured cabling
  • New lighting and Cbus Control system
  • New Distribution Boards and Power Reticulation.

Job Description

In keeping with our wonderful relationship with FDC, Kerfoot Pty. Ltd. was engaged by FDC Fit out & Refurbishment, to complete the Make good and Fit out of Levels 2, 3 and 4 of the premises at Pier 8, Millers Point, Sydney for the new tenant, Clemenger Group.

The complexity of the fit out at this particular premises proved challenging. The main one being access. Not only was it a challenge to deliver materials to the Pier, but also the access while getting them to the floors and installation due to the nature of the floor design. The heritage aspect of the Building needed to be maintained while undertaking this Fit out.

The unique design of a Federation Style 3 Storey Shed Built in the 1820-1830 period, displayed technical and creative excellence at that time.

Since then, the Wharf has had a few mezzanine levels added, which added to the complexity of the installation.

Kerfoot was engaged to complete the installation of architectural lighting, installation of new distribution boards and a complete re configuration of the structured cabling system for the new tenant.

Our team of skilled tradesman and dedicated workers ensured that the project was delivered on time and with a high level of workmanship that our building trades have come to expect of us.
