Sigma 1: Open ground solar PV panel mounting system designed to mount single (portrait) or double (landscape) rows of solar PV panels using a single row of steel posts.
The Open Ground solar panel mounting system gracefully combines structural stability and strength with a low profile, attractive finish; a feature that makes the open ground mount systems a popular choice for both landowners and planners. With the open ground system, the solar panels are the main visible element of the finished installation, the metal support structure largely disappears into the background.
Subject to the local conditions on-site the supporting steel posts can be pile driven directly into the soil without using concrete, minimising both installation times and the environmental impact of the installation.

Open Ground: System Design
Open Ground mounting system design in itself is reasonably straightforward but planning permission is required for any ground mounted system over 9m sq (approx 5 large 60 cell panels). The need to obtain planning permission could introduce other design considerations to account for any effects that the PV installation may have on local people, animals, plants, the landscape or cultural heritage.
Other system design considerations include spacing between rows of panels to avoid self shading, cable lengths and sizing to minimise voltage drop, location and housing of inverter equipment. Individual PV arrays should be 12m long or less to allow for thermal expansion.
Individual installation drawings and static loadings are provided with each order. Our in-house design team is also available to provide additional system design or planning support as needed.
Installations start with steel posts, designed to be driven directly into the soil (although footplates and other bespoke components can also be designed and supplied to suit the mounting area). The steel posts support chevrons and cross rails that in turn support the solar panel mounting rails.
Driving the steel posts will require pile driving equipment and groundworks will be required to bury power cables and conduit. We have installation engineers available to provide project management and on-site installation services as needed.
Components & Specifications
Due to the build to order nature of these systems the installation drawings and components are individually prepared to suit the characteristics of each installation site. A complete bill of materials and quotation offer can therefore take up to a week to prepare.
For indicitive pricing and any other pre-sales enquiries please contact us to discuss
Some components are manufacturered to order based on the size of the solar panels used and the panel layout. Components for each order are designed, tested, manufactured, packaged together into kits and delivered to site anywhere in the UK (including delivered to us for storage and later collection if prefered) within 3-6 weeks.
Open Ground: Guarantee
The OpenGround: solar panel mounting system is provided with a 10 year manufacturers guarantee.
