Reduce your levelised cost of energy and make projects more attractive to investors and offtakers.
The Tiltsun robot lays a gap-free flat-mount field — with a crew of just 2–4 people.
Request a custom quoteA 5 MW solar park in Skiemonys, Lithuania, built with Tiltsun's proprietary ballasted flat-mount structure and robotic installation. It is the first park of its kind in the country and the proof point for everything on this page.
The park is a remote solar solution: residents and businesses across Lithuania can buy a share of its green energy output.
Designed for large-scale solar farms, the Flat System maximises space efficiency and cuts installation complexity. An automated robot assembles and interconnects panels with precision, speed and minimal labour. By forming a seamless flat surface without the gaps of tilted or rack-mounted systems, it slashes costs, saves land and delivers high accuracy and energy output at scale.
Panels are joined edge to edge, forming a contiguous surface without the row spacing of tilted systems. No shading rows means more than three times the number of modules can be mounted in the same area compared with conventional layouts — ideal for sites where land is the constraint.
Get a custom solutionFrom engineering to ongoing maintenance, Tiltsun covers the critical phases that ensure a successful and efficient solar project.
Layout of the solar farm, panel configuration, inverter placement and electrical systems. Technical drawings and specifications for civil, electrical and mechanical works, with component selection for proper grid integration.
Land-levelling machinery creates the flat surface for the mounting system. Our ballasted system needs no digging or drilling, so we can work on a variety of soil types with minimal ground disturbance.
The fastest and most efficient method for building large-scale, flat-oriented solar parks. Streamlined robotic deployment accelerates timelines and delivers substantial cost savings for investors and developers.
Automated cleaning robots remove dust and monitor for failed modules, reducing manual labour. The ballasted design allows easy demounting and minimal environmental impact at decommissioning.

Our robot automates the mounting of solar panels. It uses advanced sensors, precision arms and positioning systems to accurately place and secure panels in large-scale solar parks. It requires minimal human supervision — typically 2 to 4 people — making the process faster, safer and more efficient than traditional methods.
Only 2 to 4 operators, depending on the size of the park. One person monitors the robot while the others manage supplies such as panels, reducing labour costs and the need for large installation crews.
Yes. It is designed for large-scale projects with numerous safety features, including real-time monitoring and emergency stop functions, keeping both workers and equipment safe during installation.
On average up to 10 times faster than a traditional human team. Exact speed depends on site conditions and project complexity, but in most cases installation time is dramatically reduced.
The robot operates on flat surfaces using a ballasted system, eliminating ground drilling. The surface must be levelled prior to installation; the robot can work on slopes of up to 10 degrees.
By reducing the labour force and installation time, the robot significantly lowers project costs. Its precision also reduces costly errors such as misalignment or material damage.
Yes. It works with a wide range of module suppliers and is designed to handle the largest panels on the market.
Absolutely. It reduces the need for heavy machinery, lowers fuel consumption and minimises material waste, while fewer workers on site lower the footprint of the installation process.
We offer free consultations to assess feasibility. We evaluate the site layout, panel type and other factors to make sure our solution is the best fit for your project.
Panels are installed without gaps, so there is no need to avoid inter-row shading. This enables more than three times the number of panels in the same area compared with conventional systems.
