Is your yard ready for a renewable energy installation?

More industrial and commercial sites are installing solar panels, EV charging infrastructure, and battery storage than ever before

What frequently gets missed in the planning is whether the yard itself is structurally capable of supporting the installation and the ongoing operational demands that come with it. Getting the groundwork wrong does not just delay a renewable project. It can compromise the asset from day one.

Why yard infrastructure matters before a renewable install

The conversation around renewable energy installations tends to focus on the technology: the panels, the chargers, the storage units, the grid connection. The ground those assets sit on rarely gets the same attention, and that is where problems tend to start.

Battery storage containers are heavy static loads. Installation involves cranes and heavy plant that place significant temporary stress on yard surfaces. EV charger pedestals require trenching, drainage, and reinforced surfaces around them to prevent movement and cracking under vehicle load. Solar racking systems mounted at ground level or on hardstandings need a stable, level base that will not shift or settle over the asset’s operational lifetime, which is typically 25 years or more.

If the yard surface or sub-base is already compromised when these assets arrive, the problems compound quickly. A crane operating over a weakened sub-base risks surface failure. Battery containers installed on an inadequately specified slab will cause cracking and movement. And poor drainage around electrical infrastructure is not just a performance issue. It is a fire and safety risk.

What the yard needs to be able to do

Before any renewable installation begins, the yard infrastructure needs to reliably support four things.

First, installation loads. Crane movements during installation are often the heaviest loads a yard will ever be subjected to. Existing surfaces that are adequate for normal HGV traffic may not be adequate for a 50-tonne crane operating from a fixed position. A pre-installation survey should assess whether temporary reinforcement or permanent slab upgrades are needed before plant arrives on site.

Second, permanent static loads. Battery storage containers in particular impose significant point loads on the surfaces beneath them. These are not moving loads that distribute across the yard like vehicle traffic. They sit in one place indefinitely. The slab specification beneath a battery container is a structural decision, not a surfacing one, and it needs to be treated as such.

Third, maintenance access. Renewable installations require ongoing maintenance. That means vehicle access, including specialist service vehicles, to equipment that may be located away from existing hard-standing areas. Access routes to solar arrays, battery containers, and EV charging infrastructure need to be specified for the vehicles that will use them, not just for the vehicles that currently use the yard.

Fourth, drainage. Surface water management around electrical infrastructure is critical. Pooling water around EV charger bases, battery containers, or substation equipment accelerates corrosion, increases risk, and in worst cases creates a direct hazard. Drainage that was adequate before an installation may not be adequate after it, particularly if new hardstanding areas alter the existing water flow across the site.

The most common yard issues that delay or compromise renewable installations

Based on sites we have surveyed ahead of planned renewable installations, the issues that most frequently cause problems are failing sub-bases beneath existing hardstanding areas, inadequate drainage in the zones where new infrastructure will be located, concrete surfaces that are technically serviceable for current traffic but underspecified for the loads that come with installation plant, and a lack of ducting provision that means trenching has to cut through existing surfaces in ways that compromise their integrity.

None of these issues are difficult to resolve if they are identified before an installation is planned and costed. All of them become significantly more disruptive and expensive if they are discovered after a project has started or after a contractor has mobilised on site.

Future-proofing the yard even if you are not installing yet

Many of the businesses that will install renewable infrastructure in the next three to five years are not installing anything today. But if you are already planning maintenance works or surface upgrades on your yard, this is the right moment to future-proof the groundwork rather than do it twice.

That means specifying drainage that can accommodate future electrical infrastructure. It means installing ducting runs during concrete pours so that cable routes do not require future trenching through finished surfaces. It means designing slab thickness and reinforcement with future static loads in mind rather than only current traffic. None of this adds significant cost when it is designed into works that are already happening. It adds considerable cost when it has to be retrofitted later.

What PKB Civils does in this context

PKB Civils does not design or install renewable energy systems. We are a specialist concrete and civils contractor focused on external yards and hardstandings for commercial and industrial sites. What we do is make sure the ground is ready before the renewable installer arrives, and that it stays in the condition it needs to be in for the life of the asset.

That includes pre-installation condition surveys, slab upgrades and reinforcement works, drainage installation and remediation, and ducting integration during concrete pours. We work around your operational schedule and, where possible, phase works to keep the site running throughout.

If you are planning a renewable installation and have not yet had the yard assessed, or if you are planning maintenance works and want to build in future-readiness at the same time, a site survey is the right starting point.

When the yard is not the issue

Not every site needs significant groundwork ahead of a renewable install. Newer yards with well-specified concrete, functioning drainage, and adequate sub-bases may need little more than ducting integration and minor drainage adjustments. A survey will tell you clearly which category your site falls into, and whether any works are genuinely necessary or simply worth considering for long-term resilience.

FAQ's

Not always, but it depends on the condition of your existing surfaces and drainage. EV charger bases require stable, well-drained concrete around them to prevent movement and cracking. If your yard surface is already showing signs of deterioration or your drainage is poor, these issues should be addressed before installation rather than after. A pre-installation survey will give you a clear answer.

Battery storage containers impose significant point loads on the slab beneath them. The exact specification depends on the container size and weight, but as a starting point, slabs beneath battery containers typically need to be designed to a higher specification than standard yard hardstanding. This is a structural question that should be assessed by a civil engineer before any container is positioned.

Yes, and this is almost always the most cost-effective approach. Installing conduit and ducting runs during a concrete pour adds minimal cost compared to cutting through finished surfaces at a later stage. If you have yard works planned and are considering a renewable installation in the next few years, ducting integration during those works is worth discussing before the concrete goes in.

No. PKB Civils specialises in external concrete yards, hardstandings, and drainage for commercial and industrial sites. We prepare and future-proof the ground for renewable installations but do not design or install the renewable systems themselves. We can advise on what the yard needs to be ready and carry out any groundworks required.
