Why solar matters for business today
The race to decarbonise is a present-day business imperative and no longer a future ambition. Across the UK and Europe, commercial energy costs have surged by over 50% in recent years, and at the same time, governments continue to tighten carbon reduction targets. Investors are demanding strong sustainability credentials as energy choices are scrutinised as closely as financial performance.
This challenging landscape coincides with remarkable growth in renewable alternatives. According to IEA, between 2018 and 2023, global solar capacity tripled, and from 2024 to 2030, it is expected to drive 80% of global renewable capacity growth, mainly fuelled by large-scale plants and expanding rooftop systems for commercial and industrial users.
Solar technologies deliver a quantifiable approach to help simultaneously manage energy and sustainability targets. Continuing declines in capital expenditure and improvements in system output make solar energy for business a smart financial strategy. It cuts business electricity bills, boosts energy independence and reinforces sustainability credentials in a fast-moving market.
Recognising that different sectors have different needs, solar is no longer a one-size-fits-all solution. Whether you're operating a logistics site, a retail chain or an industrial facility, there are options to suit your energy profile and footprint. Large-scale farms, rooftop PV, car park canopies, hybrid storage — the right solution is out there.
Equans brings long-standing technical expertise across all these applications. With over a decade of experience delivering commercial solar and storage, we support clients from planning to operation, combining global expertise with local project execution. The result is resilient, integrated energy infrastructure built for long-term value.
Rooftop PV: transforming overhead space into long-term value
Rooftop photovoltaic (PV) systems offer a strategic way for businesses to produce renewable electricity directly at the point of use. Installed on commercial, industrial or public-sector buildings, these solar energy systems make use of otherwise idle surfaces. For many organisations, this is the most practical first step in deploying solar for business.
Rooftop solar installations are used to power logistics hubs, retail outlets, public buildings and factories across Europe. Panel capacity can range from under 100 kWp for smaller facilities to several MWp for larger industrial sites. These systems deliver a reliable local energy source that reduces exposure to electricity price volatility while improving site sustainability.
The benefits are measurable. A rooftop system removes the need to acquire new land and makes use of existing infrastructure. Large surfaces, like warehouses or supermarkets, typically support high-yield arrays with fast payback periods. On-site solar panel installation also aligns with urban planning rules and minimises visual disruption. In many regions, net metering or feed-in tariff mechanisms enable users to gain credits for surplus generation, thereby further reducing business electricity bills.
Installation is relatively quick: design, procurement and construction often take 4–6 weeks, with minimal operational disruption. Over the system’s 25–30 year lifespan, maintenance costs are low and predictable. Depending on local conditions, rooftop PV may cut up to 100 tonnes of CO₂ emissions annually per MW installed.
For businesses seeking an efficient, low-impact entry into the commercial solar market, rooftop PV is a proven model. Equans supports solar roll-out and optimisation in the context of their energy, industrial and digital transitions, enabling decarbonisation without compromising land use strategy.
Solar car park canopies: turn every parking space into a solar asset
Car parks often sit unused for most of the day — wide, open spaces that serve a single function. With tailored solar canopy structures, these open spaces can convert sunlight into electricity while still allowing normal access below. Solar car park canopies involve installing solar systems that deliver two clear benefits: renewable energy production and weather protection for parked vehicles.
This type of solar installation is suited to commercial and retail centres, corporate sites, transport hubs like airports and stations, and public car parks managed by local authorities. They offer a visible sign of commitment to low-carbon strategies while improving the everyday experience for staff, visitors and customers.
For businesses, solar car park canopies monetise unused outdoor space on land that has already been stripped of much of its biological value. When designed and installed to meet green building standards such as BREEAM or HQE, business solar supports wider corporate responsibility goals.
A typical example of how solar technologies serve practical business goals, is a shopping centre installing solar car canopies to power its site while offering covered parking — aligning environmental goals with user comfort. The visible infrastructure reinforces the site’s sustainability credentials with customers and investors alike and also creates a future-ready platform for EV charging, without requiring major site changes.
Equans led a turnkey EPC project for Neoen, transforming an existing car park into a solar car park with 61 arrays, generating enough energy to power 8,800 households, delivering operational excellence from concept through to integration. These scalable, customisable structures turn underused parking areas into productive assets.
Floating PV: efficient solar where land is limited
Floating PV systems offer a practical option for sites with limited land but access to water. These systems consist of solar panels mounted on floating platforms placed on basins, reservoirs or artificial lakes. Like land-based PV arrays, they capture solar energy and convert it into electricity, using water surfaces as structural support.
This solar energy technology is particularly suited to industrial sites with cooling ponds or storage reservoirs, utilities operating hydroelectric facilities, and municipalities with treatment plants or disused water assets. It also supports businesses that face surface constraints or wish to keep operational land available for expansion.
Aside from preserving space, floating commercial solar installations improve energy yield. The water’s natural cooling effect lowers panel temperature, which increases efficiency. At the same time, these systems reduce water evaporation, a key concern in warmer climates. For organisations seeking visible climate action, this solution sends a clear signal. It also supports broader ESG goals by lowering the site’s carbon footprint and contributing to energy stability.
For example, a manufacturing site could deploy floating solar on a treatment reservoir to supply its operations with low-carbon power. This approach reduces algae growth by limiting sunlight penetration, decreases water evaporation by up to 70%, and benefits from the cooling effect of the water surface, which can improve panel efficiency by 5–10%. It also avoids additional civil works or land modification, making it ideal for constrained or regulated sites.
Equans has already delivered end-to-end expertise in engineering, civil works and renewable energy through Belgium’s largest floating solar farm. Built on a former sand quarry, it supplies low-carbon energy to a nearby sustainable industrial site — supporting decarbonisation without taking up valuable land.
Agri-PV: Cultivating energy and agricultural performance
Agri-PV (Agricultural Photovoltaics) brings together two priorities on the same land: food and energy. It’s a solution designed for businesses that operate in rural areas or rely on agricultural production. Solar panels are installed at a height or angle that allows crops to thrive underneath, balancing light exposure and shelter while generating clean electricity.
This setup is ideal for agricultural cooperatives, agribusinesses and farmers looking to reduce their exposure to unpredictable energy pricing. Instead of competing with crops for space, Agri-PV maximises land productivity. The panels contribute to lower business electricity bills while giving crops partial shade, which can be valuable in regions exposed to high temperatures or hail.
But the benefits go beyond energy. Many Agri-PV systems contribute to EU and national targets for renewable energy development and sustainable agriculture. Some farmers also resell surplus electricity into the grid, generating additional revenue. Others use the solar output directly on-site for cold storage, irrigation systems or machinery.
Example: A vineyard owner integrates Agri-PV across rows of grapevines using elevated, semi-transparent solar panels. These bifacial modules are mounted on tracking structures that adjust tilt angles to optimise sunlight capture while allowing sufficient light diffusion to the crops below. Simultaneously, the PV array mitigates heat stress and hail damage, stabilising microclimate conditions and potentially improving grape quality and yield.
Equans has designed and installed Agri-PV systems that integrate seamlessly with working farmland. On the Gooiker family’s site in Zulte, we erected 3,700 m² of elevated solar panels across their agricultural land with an annual production of 43 GWh. It’s a forward-looking investment for agricultural stakeholders aiming to modernise their operations with solar for business.
Retrofit PV: turning underused assets into productive solar installations
Retrofitting solar technologies onto existing or degraded assets offers companies and public authorities a practical path towards decarbonisation without compromising valuable surface area. These systems use land or infrastructure that is no longer serving a core operational purpose — such as closed landfills, vacant plots or deteriorating rooftops — and turn them into active, low-carbon energy sources.
For organisations planning renovations or modernisation works, solar installations often fit seamlessly into the project. Instead of dealing with land purchases or extended permit application timelines, investment shifts toward boosting energy performance within current assets. Business solar becomes a valuable part of broader ESG commitments, especially for property developers and industrial site owners looking to meet evolving regulatory standards and sustainability goals.
Retrofitted systems also offer value beyond carbon impact. They lower long-term energy costs, raise property value through improved EPC ratings, and position buildings or public assets for better climate resilience. Because of their flexible design and modular construction, they can be adapted to a wide variety of surfaces, from uneven terrain to degraded concrete.
Local governments have also adopted this approach to bring idle sites back into productive use. For example, a town might repurpose a disused military base by installing ground-mounted PV systems across the cleared terrain. The site’s flat topography and existing grid connections minimise civil works and reduce project lead times. The contractor designs and deploys a utility-scale solar installation, integrating inverters, cabling and monitoring systems to optimise yield. The energy produced is injected into the local grid or allocated to public facilities under a PPA.
Battery storage: supporting solar uptime
Battery storage systems play a central role in solar technologies for businesses. They store excess electricity generated during the day and release it when needed, especially during peak usage hours or when solar production dips. This stabilises energy use and supports uninterrupted operations.
For industrial clients with irregular loads, battery storage improves planning and cost control. It cuts electricity bills by limiting reliance on unpredictable grid tariffs, especially during peak hours. When combined with commercial solar, it makes on-site energy supply more stable and supports your shift toward low-carbon operations.
Many businesses use storage for peak shaving and backup power. These applications are increasingly valuable across sectors such as manufacturing, logistics and public services.
Smart energy management: using data to improve solar value
Solar installations deliver immediate benefits, but their full potential emerges when they operate as part of a connected energy system. For commercial and industrial environments, real-time coordination is key. That’s where Energy Management Systems (EMS) and Supervisory Control and Data Acquisition (SCADA) platforms come in.
These systems gather data across production, storage and consumption points—tracking variables like solar output, building load, battery charge levels and grid import/export. With a unified interface, facility managers can monitor site behaviour minute by minute. This allows for automated load shifting, dynamic peak shaving and demand-response participation. It also improves operational continuity during energy events or supply fluctuations.
Equans deploys scalable EMS solutions that adapt to diverse sectors and site types. These platforms connect solar technologies with broader systems, including HVAC, industrial equipment, lighting and EV charging infrastructure. Algorithms optimise self-consumption by forecasting loads and tracking with solar production curves.
Through analytics and custom dashboards, businesses gain control and consistency. They reduce their carbon footprint, maintain performance during market uncertainty, and support strategic energy reporting. EMS and SCADA make commercial solar installations smarter, more robust, and integrated into long-term infrastructure planning.
Solar for business: part of a bigger system
Solar for business works best when it’s not on its own. With battery storage and smart energy tools, the system stores power when it’s cheaper, using it during peak demand, and keeping operations balanced.
Battery storage smooths out the gaps, and businesses stay on top of usage across every location without having to second-guess peaks, dips or waste.
At Equans, we build each solution around real operational needs. With profound technical expertise in B2B projects, we turn solar into a tool that supports your site, your teams and your energy goals.
