Services & Energy management

Your solar investment, managed for the long term

A solar system is not a one-off purchase. It is a 25-year asset, and what you get out of it depends on how well it is run, monitored, and maintained.

Too many businesses treat installation as the finish line. In reality, it is the starting point. The value of your solar PV system compounds, or erodes, based on three levers: how it was financed, how intelligently it is operated day to day, and how well it is protected against faults and underperformance.

This is where Wewise's energy management and service offering comes in. We don't just build solar systems. We finance them without capital outlay, run them with real-time intelligence, and back them with maintenance and a performance guarantee for as long as you own the asset.

Financing that removes the upfront barrier

The biggest obstacle to solar adoption isn't conviction. It's capital. Solar as a Service, our in-house power purchase agreement (PPA), removes that barrier entirely.

We design, install, and maintain your solar system at no upfront cost. In return, you pay a fixed monthly fee and buy your electricity at a reduced rate for the duration of your agreement, typically 10 to 25 years.

For businesses exploring solar energy financing, the case is straightforward:

Zero upfront capital investment: we fully fund the installation
A fixed monthly fee, with no exposure to grid price volatility
Lower electricity costs from the day your system goes live
Price and supply stability secured for up to 25 years
Full turnkey delivery: planning, installation, administration, and maintenance, all handled by Wewise

Backed by DCC, a FTSE 100 company with £20bn revenue in 2024, Wewise brings the financial strength to make solar financing for businesses a genuine alternative to traditional lending. This means immediate cash benefits and none of the procurement complexity.

Intelligence that runs your system automatically

Once your system is live, the question becomes operational: is it producing, storing, and selling energy at the right moment? That's where our energy management system comes in.

Acting as the control layer behind your solar and storage assets, it continuously analyses your site's energy demand, solar output, battery state of charge, and live grid prices. It then determines the most cost-effective strategy at every moment, then executes it automatically.

The result is a system that optimises rather than simply runs

Maximised on-site solar use

Your own generation is prioritised first

Lower costs, automatically

Energy is stored when prices are low and deployed when tariffs peak

Reduced demand peaks

Smoother consumption limits network charges

Coordinated control

Solar, storage, and flexible assets work as one system, not in silos

Monitor performance. Prove impact.

Above this sits a real-time monitoring platform, giving you a clear view of generation, storage, and consumption performance, alongside auditable CO₂ and ESG reporting your sustainability team can use without extra workload.

Protection that safeguards your investment

A solar system performs only as well as it is maintained. Our operations and maintenance (O&M) service is built to protect that performance for the system's full lifetime.

This means rigorous, proactive care: routine panel cleaning, meter-based monitoring, and rapid fault detection, whether your installation is rooftop, canopy, or ground-mounted. We work exclusively with Tier 1, quality equipment, and every contract includes a dedicated Solar Manager and a service level agreement for its full duration.

A guarantee that turns projections into commitments

Confidence shouldn't rest on assumptions. That's why every Wewise system comes with a kWh generation guarantee.

Once validated, your system receives a guarantee certificate detailing its expected yield. We monitor performance throughout the guarantee term and coordinate maintenance automatically if output falls short, and you are compensated accordingly. For a solar PPA agreement, this guarantee is what makes the financial case rock-solid, not just plausible.

One partner, the full lifecycle

Financing, intelligent management, maintenance, and guaranteed performance aren't separate services. They are four dimensions of the same commitment: that your solar investment performs as designed, for as long as you need it to.
