Solar PV Installation

  • Scaffold

    In order for engineers to safely fit the panels on your roof we will need to erect a scaffold on the face of the building where the panels will be installed. The scaffold is erected to reach slightly over gutter level. This ensures the safety of those working on the roof with compliance to all relevant Health and Safety codes. Crawlers are used on the when the roof tiles are slippery or fragile.

    The scaffold will be erected by an accredited and CTS approved contractor, usually the day before installation and removed the day after. The full cost of the scaffold is included within the quote we provide.

    Installation of the Roof Anchors

    The installation engineer will check the measurements taken during the initial site survey, make any changes as required and identify the appropriate positions for the roof anchors. This process is key to ensure an even weight distribution across the roof area, secure the panels in extreme weather conditions and to optimise the panel positions with the roof area.

    One roof tile is removed to allow the anchor to be securely fitted directly to the rafter. The tile is then slid back into position to ensure the roof remains watertight. It is important that the correct type of anchor is used to prevent damage to the tiles and the integrity of the roof.

    Attaching the Frame

    Once all the roof anchors are fixed into place, the aluminium rails that make up the frame are then secured into place. Every rail is checked to make sure that it is straight and parallel with each other. This process will ensure that panels look even and level with the roof line, a small error on one side will magnify itself as more panels are added, so it is important to get this exactly right.

    Installing the PV Panels

    Once the rails are in place the frame is complete and the panels can be clamped to the frame. A minimum of four clamps per solar panels are fitted, though more can be fitted as the installation requires. The panels can be fitted in landscape or portrait format, though portrait is usually the most popular direction.

    Wiring the PanelsĀ 

    Each panel comes prewired from the manufacturer with specific, safe and watertight solar connections. The installer connects the panels in series and then extends the final two positive and negative connections to be connected into the DC Inverter.

  • Installation

    Installing the Inverter

    The solar inverter is best positioned as close to the panels as possible so it is usually installed within a loft space, though other dry and secure positions can be identified. The inverter converts the DC electricity provided by the panels into AC electricity which your house can use. Isolators are fitted to the incoming and outgoing feeds to enable safe maintenance of the unit.

  • Installation

    Connecting to the property electricity supply.

    The final aspect of the installation is to connect the AC feed from the inverter unit into the house electricity supply. This will enable the property to use Solar electricity during the day and sell any surplus back into the grid. The electrician will first install an OFGEM approved solar generation meter so you can take meter readings to claim the feed in tariff and then connect into the existing fuseboard.

  • Testing and Commissioning.

    The whole system is now fully tested and commissioned to MCS standards, with all the results submitted to the government body “Gemserve” so an MCS certificate can be issued to enable you to claim Feed In Tariffs. This process can only be undertaken by MCS approved companies like CTS Renewables, and is of vital importance for you to get a return on your investment.

    The whole installation will be provided by engineers trained and accredited to MCS and NICEIC installation standards.
