Transform your car park into a power plant without losing a single parking space!

Solar carports

RenEnergy’s solar carports provide clean, cost-effective energy for your business by transforming your existing real estate, car park or even your multi-story carpark that are otherwise underutilised and most often without losing a single parking space!

We design, supply and install each custom-made solution to maximise available space and energy yield, engineered from the ground up. We’ve refined innovative designs to offer cost-efficient, competitively priced solutions. Apart from the technical design of the solution, we design practical ergonomic solutions that take factors such as driver visibility, vehicle door opening and traffic management plans into account.

Our commercial solar carports comprise a bespoke structure with high-spec solar panels that are energy dense and provide good yield. The compact design and innovative ground fixings allow a quick and efficient build, with minimal disruption to your site. As well as improving your onsite parking, our solar carports also provide an impressive display of your commitment to sustainability. 

The structures can accommodate energy storage, allowing you to use your solar energy beyond daylight hours, and electric vehicle (EV) charging points to meet increasing EV charging demand.

All RenEnergy solar carports can be equipped with a range of technologies, either during installation or retrofitted:

Intelligent energy management to power your business while saving on energy bills

Energy Storage / Battery Energy Storage Systems (BESS)

Solar energy works best when it’s intelligently stored and strategically deployed. Without energy storage, excess solar must be used in real time or exported to the grid. But with storage in place, surplus energy is saved for later, enabling your business to use more of what it generates, reduce reliance on fossil fuels and secure a more consistent, predictable energy supply.

Shift + Save: Energy storage as a financial strategy

Our Shift + Save energy arbitrage solution uses smart controls to store energy when it's cheap and dispatch it when it's expensive - turning your solar and storage into a financial asset. Whether your system is new or already in place, Shift + Save unlocks greater ROI by aligning your energy use with tariff windows. The result? Strategic savings, faster payback and greater resilience. Flexible battery storage solutions that store surplus renewable energy and provide peak‑shaving and resilience.

Intelligent storage solutions that store surplus energy, reduce peak demand, and improve resilience.

Typical applications include

  • Shift + Save energy arbitrage – charge from solar or low-cost grid supply, discharge during peak tariff periods

  • Onsite electric vehicle (EV) charging – power electric vehicle chargers for staff and visitors using your own solar and storage

  • Peak shaving – limit your draw during maximum demand periods

  • Excess solar harvesting – capture and store surplus generation, especially in summer months

  • Increased self-reliance – reduce exposure to grid instability and rising costs

  • Diesel reduction or replacement – substitute expensive generator usage with clean stored energy

  • Internal demand capacity increase – power expansion without new grid connection upgrades

If your business is already using solar – or thinking about it – you could be leaving significant value on the table. Our team will help you model the savings, define the business case, and deploy the right energy storage and charging solution to support your energy and sustainability goals.

The RenEnergy approach

  • Scalable lithium-ion battery systems

  • Intelligent energy management software for optimised dispatch

  • Seamless integration with solar PV, EV charging, and grid supply

  • Designed for safety, redundancy, and future expansion

Benefits for the public sector

  • Reduced peak demand charges

  • Improved energy security and continuous power for critical services

  • Optimised use of on‑site renewable generation

  • Foundation for future smart energy strategies

  • Maximise return on renewable energy investments

Our EV charging solutions enable public sector organisations to accelerate fleet electrification, encourage the uptake of sustainable transport, and meet decarbonisation targets with confidence. Scalable by design, the infrastructure can grow in line with future transport demand, while public-facing chargers offer opportunities to generate revenue and enhance community access to low-carbon mobility.

Consultancy

RenEnergy provides focused consultancy for renewable energy generation, energy storage and electric vehicle infrastructure tailored to public sector organisations. Our advice is grounded in delivery, not theory. By using our own planners, surveyors, engineers and project managers, we bring first-hand knowledge of designing and delivering complex energy projects within public sector environments, governance structures and budget constraints.

This integrated, in-house approach allows us to remain flexible in our recommendations, develop bespoke technical solutions to address site-specific and operational challenges, and offer cost-effective consultancy that delivers genuine value. Our focus is always on identifying the right technology mix to support your organisation’s priorities, whether that’s meeting net zero commitments, ESG objectives, energy security requirements or improving resilience against volatile energy costs.

We work in partnership with you to fully understand your strategic drivers and policy context, taking the time to translate complex technical and commercial information into clear, accessible insights. This ensures informed, evidence-based decision making at every stage. From early strategy development and portfolio reviews across multiple sites. Through to technical feasibility, business case development and grid engagement and onto detailed design, planning and approvals. RenEnergy provides end-to-end support to de-risk investment and enable successful delivery of future-ready public sector energy infrastructure.

Public sector Asset Management + performance assurance

Asset Management

RenEnergy’s Asset Management services are designed to protect public sector investment and ensure renewable energy assets deliver reliable, long-term value. Through proactive monitoring, planned maintenance and performance optimisation, we help maximise efficiency, minimise downtime and maintain consistent energy generation. This supports your budget certainty, operational resilience and decarbonisation goals.

RenEnergy take a performance-led approach to maintaining the benefits of your energy solution over its full lifecycle. Using continuous remote monitoring our teams identify and resolve issues early, reducing the risk of disruption to critical public services. Tailored operations and maintenance plans ensure each system is maintained in line with its technical requirements, while remaining cost-effective and compliant with public sector expectations.

Although solar and renewable energy systems are inherently low maintenance, regular servicing and technical cleaning are essential to sustain output and asset longevity. Environmental factors such as dust, pollution and debris can significantly reduce performance if left unmanaged. Our structured maintenance programmes ensure systems continue to operate efficiently year after year, delivering dependable returns and long-term peace of mind.

RenEnergy’s services include:

  • Planned annual servicing to prevent faults and reduce unplanned outages

  • 24/7 remote monitoring by an in-house team to safeguard performance

  • Data-led optimisation to identify improvements and corrective actions

  • Responsive technical support to resolve issues quickly and minimise disruption

  • Quarterly and annual performance reporting with clear insights for stakeholders

  • Feed-in Tariff (FiT) verification, where applicable, to protect income accuracy

  • Professional panel cleaning to maintain optimal generation

  • Maintenance and repairs delivered promptly to restore system performance

Together, these services ensure public sector energy assets remain efficient, resilient and aligned with long-term sustainability and value-for-money objectives.
