Municipal & Utility Applications: Landfills

Landfill Solar

The challenge of "Landfill" solar farms

Many local governments are looking for ways to turn dormant landfill sites back into productive land that benefits the taxpayer and the community at large. Similarly, many utilities and real-estate developers are looking for new and innovative ways to generate renewable energy as a way to lower costs or generate revenue. While solar farms appear to be the perfect solution, the current, accepted approaches and practices leave a lot to be desired ....


1.      Damage to the Cap:  With the traditional approach, significant excavation work is needed to dig the trenches needed to install traditional solar arrays. However, this invasive process and the heavy, earth-moving equipment it requires pose a real threat to the integrity of the landfill cap. Also, the intense weight of the system doesn't allow for the landfill contents to naturally settle over time.

2.      Site Preparation:   Significant site work is required prior to installation to adapt the surrounding terrain to the required grade needed to accommodate traditional solar arrays. Additional site work is often required AFTER installation to counter the invasive nature of the installation in an effort to return the site back to its "pre-installation" state.  This additional, often unanticipated work adds significant costs, disrupts the site's ecology, and causes cost overruns that exceed established budget constraints.

3.      Project Costs and Timelines:  The very nature of the current, accepted practices for assembly and installation of side-sloped solar requires a long, drawn-out, and costly process that can take many months to complete.

4.      Environmental Impact Not only does site preparation and traditional installation take considerable time and effort to complete, but it scars the local terrain, disrupts the local wildlife habitats, and requires considerable use of fossil fuels.

For these reasons, Anar Solar’s pateneded approach for landfills is the perfect solution.

Anar Solar for Landfills

Introducing the Anar Solar approach

Anar Solar’s patent-pending approach was specifically developed to address the inherent challenges associated with landfill installations. We do not use concrete or invasive fasteners that can threaten the integrity of the cap. Instead, our non-invasive, above-ground ballast system distributes the system weight evenly across the entire site area which allows for settling.  It can be configured for any existing elevation and contour variations, and side slope stability is maintained through the use of vertical “North-South” ballast positioning that adapts to the site’s existing contour.

Anar Solar - Ballast

Our ballasted platforms provide a foundation for each array that will not damage the landfill cap or disrupt landfill settlement, making it possible to install on any terrain with no impact to the cap or the site environment. Since the assembly and installation procedure requires no field trenching or site grading, no heavy machinery or equipment is needed, and any impact to the site and its ecosystems is minimized. Our design is simple and uncomplicated, user-friendly and noninvasive.

Residential Solar

Our patent-pending racking system can be fine-tuned to optimize the system’s power-generating capability. And, our simplified  assembly, and installation process reduces fossil-fuel use and the associated labor and maintenance costs, thus making Anar Solar’s approach the most efficient, economical, and eco-friendly landfill solution available on the market today.

More Information:

The Anar Solar patent-pending ballast system uses corrugated drainage pipes located above ground and interconnected using specially designed clamps. This approach allows the system to configure to existing elevation and contour variations mitigating site work and grading. The clamps encase the ballast tubes and provide support for the array. The racking system simply attaches to the clamps, and any existing racking system can be adapted by simply changing the brackets that mount to the clamp assembly. Minimal nuts or bolts are used, making installation and adjustments less labor-intensive and faster than other appraches currently available on the market.

Electrical wire management is incorporated inside the ballast tubes, which eliminate the need for field trenching for conduit runs. Junction tees are installed at designated intervals to accommodate combiner boxes. An end-cap with drainage ventilation is placed on both ends of each array, and an eco-friendly, impervious slurry material is pumped into the ballast tubes to weigh the system and encase the electrical conduit inside. The ballast distributes the weight-bearing load over the entire array location.

The ballast system is placed in a vertical “North-South” position to overcome the obstacle of side slope stability. The interconnected piping is extended past the array location, over the landfill peak, to further anchor the system. Differential settlement within the landfill is not a problem because the electrical lines are encased in the ballast tubing and will not be affected by ground conditions. This design offers the most secure structure without harming landfill settlement.

Our racking system is fully adjustable as well, and can be repositioned within a range of 18-28°. This allows the solar panels to adapt to settlement and capture sunlight with maximum efficiency.
