Solar charging for electric vehicles


The challenge

The Partners wish to encourage and enable the use of electric vehicles across their estate to reduce carbon emissions and support those in social housing. They will do this by providing a large amount of charging points to their estates which ranges from leisure centres to residential homes with driveways.

They wish to do this in the most sustainable way possible by aiming for zero carbon. Currently they have roof mounted and canopy mounted solar PV arrays in place, and separate EV charging points. However, these are not yet coupled together into one system and therefore the ideal solution would take the form of PV systems coupled with battery storage, providing EV chargers which are controlled by a robust third-party payment system.

The Partners are looking for a provider of this type of combined solution.

The solutions we are seeking

The Partners are seeking a replicable and scalable solution to provide EV charging from renewable energy. Ideally, the solution could be applied to larger buildings such as leisure centres and to smaller buildings such as homes.

A solution applied to larger buildings such as a leisure centre may need to integrate with the Partner’s current infrastructure and demonstrate a flexibility to work with existing contractual relationships. The Partners are at various stages with their electric vehicle charging roll-out, so a modular solution would be ideal.

A domestic solution is envisioned as providing solar charging points in tenanted residential homes, enabling the owners to charge their vehicle in the safety of their home. The equipment would be loaned to the tenant’s property and the energy sold to the tenant via a smart charging mechanism.

Solutions will only be applied to off-street sites, as the current infrastructure is not capable of supporting on-street charging.

A solution that demonstrates management of power and not exporting of power would be preferable.

Selection criteria

Availability of technology, quick ROI.

Minimal space requirement, and demonstrated ability to work within existing infrastructure.

Cost needs to be competitive.

Demonstrate reduced grid draw and increased self-sufficiency.

The Partners would expect a healthy return within 3 years and look into the possibility of upselling other products to maximise the benefit.
