The installation of photovoltaic panels on a roof varies according to the type of installation: partially integrated using rails fixed to the tiles or totally integrated with installation on waterproof elements under the roof covering. Here are 5 tutorials covering the different methods of installing Solar Panel Sydney.

Laying photovoltaic panels: the various configurations

Photovoltaic panels are mainly installed on roofs (30 to 35 degree inclination and south orientation are recommended) and their fastening systems differ and affect the ease of installation , the necessary accessories, the duration of the intervention , the degree of competence and the tools needed for installation. From laying the tracks over the roof to removing the shingles to installing a waterproofing system or protection under the roof, costs vary considerably. The installation of solar panels allows the production of electricity; their pose is related to different parameters. The choice of solar panels, according to defined criteria, requires a preliminary study and a precise definition of the needs of the system and the accommodation.

Skills:

To install solar panels, you need to be comfortable with working at height and on roofs and be competent in waterproofing to prevent water infiltration. You will need to ensure that the panels are well fixed which must withstand adverse weather conditions, by installing rails, hooks, brackets or battens. Also read the instructions, know how to read a connection diagram, work in safety (electrical intervention) install and connect an inverter, connect the electrical cables and fix them to the wall, know how to use a drill-driver and a circular saw are prerequisites Solar Panel Price in Australia. Depending on the solar panels and their fixing method, it may be necessary to install an under- solar Panel Price in Australia waterproofing membrane or a waterproofing system (by crimping in the first case and screwing in the second). Good physical fitness is also required to work on a roof and handle photovoltaic panels .

This tutorial allows you to have a broad view of the installation of photovoltaic panels. At the end of the guide you will find other tutorials made by individuals and in different configurations that allow you to have a more precise view of the installation.


1. Remove the tiles in the area intended for the solar panels


We distinguish two different cases. If your roof is covered with shingles or slate, you will need to partially remove it. You need to start by defining the precise area where you intend to install the solar panels. You must therefore remove the tiles on a surface slightly larger than that of the panels to be laid . Once this operation has been done, a hole appears in the roof: the photovoltaic panels will be housed there after careful preparation. Remove the tiles using protective gloves as the tiles are sharp and can injure your hands. Any intervention on the roof must be carried out with a fall arrest system (fall arrest net or harness with lanyard). If you remove the shingles near the ridge, be careful not to break the ridge tiles or half-tiles (do not walk near and lift the shingles gently).If your roof doesn't have planks, don't walk between the battens or on the under-tile waterproofing membrane , as you risk falling

.

2. Install the bottom and side flashings

The flashings are connecting plates between the roofing materials, in your case the tiles or slates, and the different elements that protrude from the roof, here the solar panels and their fixings. The flashings make it possible to create perfect waterproofing. There are flashings suitable for every model of tile, both in terms of shape and color. For slates, this is a slate-colored flashing or a zinc plate, old-fashioned. The installation of the flashings consists in the fixing with screws on the existing battens or on the added battens. The use of a screwdriver is necessary, as well as that of the tape measure to bring back the exact measurements. Hooks or brackets also attach with screws. If necessary, add a joist along the length of the panel and behind the first row of tiles, to gain height and give the flashings a better foundation Best solar pannel company in Australia. The flashings can also be made of plastic and delivered with the kit, or a lead ribbon that should be unrolled between the previously installed rafter and the first row of tiles. The lead tape (of variable width) is glued using silicone glue applied with an extrusion gun . The lead strip, deformed by hand, marries the shape of the tiles. The boards and battens are cut with a circular saw .


3. Lay the attic protection or a waterproofing system


Lying of the attic protection. During the construction of a roof covering, an under-tile protection must be installed. It is a plastic technical film that serves to create a barrier that is impermeable to water but not to air. When installing this attic protection, it is recommended to create an air gap between this protection and the insulating panels to avoid any risk of mold (the protection is generally placed and seamed on the joist in the traditional structure).
