Installation Basics: Solar panels are not supplied as standard with any mounting brackets or cables other than the industry standard connections for “national grid installations”. This is because even though solar panels are relatively simple to install, virtually every installation is a bespoke project with unique requirements. Most end user customers and installers prefer to source their own cables and brackets based on these specific requirements.
For connections to a battery, or battery-bank you will require “Twin Sheathed (Double Insulated) 2 Core Cable for the connections from your panel/s to the charge controller and then to the battery/ies. The cable must be rated to the required amperage for your installation and is available from any good local electrical/DIY retailer, or your installer.
Likewise, the means of securing your solar panel in position are as many and varied as the applications for which solar panels can be used. For boat, caravan, motor home user it can be as simple as using a professional strength adhesive such as Sikaflex (also available from any good Chandlery – but you will have to sell the solar panel with your boat etc. as it’s there to stay!). For walls, tiled roofs, sheds, poles etc you will need to buy/create different means of fixing.
Should you prefer for us to put together a basic “installation kit” that is based on the solar panel/s you order here, please provide the necessary information by Emailing us here with as much relevent information as possible including: Where you wish to mount the panel/s, distance to batteries, etc.
