The solution was easy to install and minimises maintenance…
A roof-mounted PV array was chosen for the site, and for a number of reasons. Importantly, it would reduce the overall cost of the system, minimise risk of downtime and disruption (unexpected underground obstructions) and remove the need for ground reconstruction work, for example re-tarmacking. Longer term, it reduces the need for extra maintenance, and because a roof mounted system uses shorter cable runs this would also improve array efficiency.
Infinity installed a Solar Panel system using 320W poly-crystalline panels and a 50 kW inverter. The system will provide excellent savings on annual electricity costs, and a project payback period of only 8.5 years.
