Frequently asked questions

No. The RAPID ROLL’s modular, resilient electrical architecture optimises the performance of individual sections of our “solar mat” for the particular light conditions (due to slope and shading) which may happen to occur when deploying in different locations. For this reason, it’s not necessary to have solar engineers model the specific site and calculate particular solar field positions and configurations before deployment – the Rapid Roll will work anywhere and will make the most out of the set of conditions encountered.

Our objective is to demonstrate performance in -40C to +50C during 2017, although field testing to date (Sept 2016) has included a range of 0C to +38C. Components are typically rated for -40C to +80C operation. In terms of locations, the system can provide value in operations in remote places for most global locations/latitudes as far as the Arctic Circle. The flexible CIGS technology used in the RAPID ROLL is particularly good in low light and power production is possible from diffuse light or with low incident angle of sunlight in higher latitudes. The optimum performance typically occurs between the tropics and in some of these locations 365-day self-sufficient operation may be possible.

The RAPID ROLL solar field is waterproof, but should be deployed on a location which is well-drained or slightly sloping to avoid it becoming submersed. Incredibly with the CIGS technology used in RAPID ROLL, solar power production is often even possible in light rain!

The RAPID ROLL solar field should be fixed down by stakes, bolts or anchors when left unattended. We have tested this fixing method in wind speeds up to 80mph with no problems. If a very severe storm/hurricane is forecast, the RAPID ROLL solar field may be stowed away in advance of the storm to protect it – a key advantage compared with fixed panel systems.

Yes, critical components have been vibration/shock mounted to deal with these scenarios. For particularly severe shock applications (e.g. underslung heavy landing) an enhanced shock protection package is available.

Occasional foot traffic is not a problem, although the RAPID ROLL solar field should not be used as a walking surface. Vehicles should not be driven on the RAPID ROLL solar field as this may cause damage (although damage is unlikely if deployed on a solid surface such as concrete).

No, the RAPID ROLL contains no moving parts and so it’s extremely quiet during operation. In very warm conditions (30C+) you may hear a hum of the ventilation system. When utilising HyPER-FST hybrid functions, the generator auto-start may be supressed in order to continue silent operation if required.

In Europe IP67 IEC 60309 “commando” style 32A output sockets are provided. For North America NEMA “L” twist-lock 20A or 30A sockets are provided. Other custom socket options are available on request.

A single RAPID ROLL “T” system provides power equivalent to 4 UK households, or a 120-bed mobile clinic. It could also be used to power desalination equipment to produce 25,000 litres of water every day or to power a peacekeeping headquarters or small FOB.

Yes, 2 optional built-in USB ports are provided, although in reality this is underplaying the performance of the RAPID ROLL system which could provide up to 5,000 smartphone charges every day from just one system!
