Frequently asked questions

Sentinel™ is an intelligent energy management service that works alongside solar panels and battery systems. Think of it as a quiet guardian for your energy system. It continuously monitors system performance, identifies opportunities to improve efficiency and, in many cases, optimises how energy is stored and used. The aim is simple. To help reduce electricity costs and ensure the system performs as well as possible. Most importantly, Sentinel works quietly in the background so the benefits can be realised without needing to manage the complexity

Sentinel is designed for anyone with a solar and battery system who wants to get more value from it. This includes homes, businesses and schools. It is particularly suited to those who: Want to reduce electricity costs through smarter energy use Are interested in earning additional income from their battery Prefer their system to be monitored and managed professionally Do not want to deal with the complexity of energy optimisation themselves In simple terms, Sentinel is for systems that are not just generating energy, but are ready to be managed more intelligently.

Sentinel is available in three tiers, allowing systems of all sizes to benefit from different levels of optimisation. Sentinel Protect™ Provides professional monitoring and system oversight. It ensures the solar and battery system is performing correctly and alerts our team if something needs attention. Sentinel Flex™ In addition to monitoring, Flex allows the battery to participate in energy flexibility opportunities with the electricity grid, where suitable, helping unlock additional value from stored electricity. Sentinel Optimise™ This is the most advanced option. Sentinel actively manages the system to maximise financial benefit, intelligently deciding when to store energy, use it or export it. All tiers share the same goal. Helping the system work smarter so more value is gained from renewable energy.

Solar panels and batteries are excellent technologies, but they perform best when they are actively managed. Electricity prices change throughout the day. Grid trading opportunities appear and disappear. Energy usage patterns shift. Without optimisation, even a well installed system may not always operate in the most efficient way. Sentinel continuously looks for opportunities to improve how the system works so as much value as possible is captured.

Yes. Helping reduce electricity costs is one of its primary purposes. Sentinel helps ensure the system is operating intelligently. It can store energy when electricity is cheaper, use stored energy when grid prices are higher and ensure solar generation is used as effectively as possible. Over time this optimisation can significantly reduce electricity costs.

Not at all. Energy optimisation can be complex behind the scenes. That is precisely why Sentinel exists. The technology and monitoring are handled automatically and supported by experts. The system simply performs in the background without requiring manual input. Sentinel removes the complexity so the benefits can be realised without ongoing management.

Yes. A twelve month trial is available so the benefits can be experienced first hand. This allows system performance and optimisation to be seen in practice before subscribing.

Traditionally, solar installations have focused on generating electricity rather than actively managing it. Once installed, systems would typically run on default settings with limited ongoing optimisation. While this still provides savings, additional value is often left untapped. As energy markets have evolved, actively managing energy has become increasingly important. Sentinel represents this next step, turning a solar and battery system into an intelligently managed energy asset that continues to adapt and improve over time.

With Sentinel™ your first 12 months are free. At the end of your first 12 months, you can continue your subscription for either £19.99 per month or £199 per year. The price is the same irrespective of whether you choose Protect, Flex or Optimise.
