SolShare™️ is the world’s only hardware for connecting a single, grid-tied solar PV system to multiple, separately metered units behind-the-meter. This innovative technology is being used across the UK to reduce the energy bills and increases SAP/EPC scores of flats.

As part of SolShare’s market entry into the UK, Allume conducted a thorough compliance and acceptance signoff process, which included meeting with all relevant governing and industry bodies.

If you require any further information or documentation on the below, please makes a request via

UKCA Certification

SolShare is fully compliant for installation across the UK and holds the UKCA mark. By holding the UKCA mark, SolShare adheres to all relevant electrical regulations and British Standards.

DNO and ENA Acceptance

All UK Distribution Network Operators (DNOs) and the Energy Networks Association (ENA) have reviewed and accepted SolShare for installation across all UK networks.

Note: As SolShare is not a power generating device (PV inverter) it cannot and does not need to be ‘type test’ certified. As such, SolShare is not required to be a type test certified product.

Ofgem acceptance for ECO4

SolShare underwent a rigorous review by Ofgem and is classified as an ‘innovation measure of substantial uplift’ for the ECO4 funding initiative. This classification ranks SolShare as a ‘technology that is a significant improvement on the closest alternative’.

This classification unlocks a 45% funding uplift on ECO4 projects.

SolShare was submitted to Ofgem by E.ON and can be found as ‘Innovation Measure Number 18’ in this document.

MCS acceptance for certification

The Microgeneration Certification Scheme (MCS) confirms that solar PV systems using SolShare can be installed according to relevant MCS standards. 

Each flat receives an individual MCS certificate based on its associated kWp following commissioning.

More information can be found in the Allume document ‘0799_Allume_SolShare_How-to-Apply-for-G99-and-MCS_UK’

Note: As the SolShare is not a power generating module (PV panel) the MCS have confirmed that it cannot and does not need to be MCS product certified.

SAP acceptance for assessments

SolShare is applicable for SAP 10.2 PV credits.

Under SAP 10.2 it falls under M1.2.a:

If the PV output goes to particular individual dwellings, the electricity generated is credited to the dwellings concerned. This applies to calculation of CO2 emissions, primary energy and fuel costs.

When a SolShare system is installed, the precise kWp associated to each flat is set during the commissioning process. The solar installer will use this value to apply for each flat’s individual MCS Certificate. This individual kWp value is used for the flat’s SAP assessment.

Assessment software companies like Elmhurst Energy have confirmed that SolShare should be included in SAP assessments under the ‘one dwelling’ option. Specifying the exact kWp associated to each flat for this.

SHDF Wave 1 & 2 applicable

SolShare has been included in numerous successful SHDF Wave 1 & 2 bids.

Even though SHDF Wave 1 & 2 are a fabric first approach, SolShare solar systems are able to be included in bids as long as it was part of the 50% contributed element of the bid. This has been confirmed following meetings with the SHDF team at BEIS. If you would like confirmation, please contact your Turner & Townsend SHDF representative.

10-year warranty

SolShare is supplied with a 10-year parts a labour warranty.

SolShare has live fault monitoring, so if there are any performance or technical issues, Allume Energy are immediately notified over-the-air and can arrange for a service call to assess and rectify the issue.

SolShare meets TrustMark Framework Operating Requirements V2.6 requirements, most notably Section 15: Product Suitability.

Installation Quality Assurance

To ensure the SolShare is installed safely and appropriately, only certified SolShare Installation Partners can purchase and install the SolShare. Certification is achieved by completing comprehensive training modules.

Certified installers are provided a unique code. A SolShare system commissioning process can only begin once the installer has entered their unique code into the commissioning app.

The SolShare commissioning process involves a rigorous, automated inspection procedure to ensure that the system is connected correctly before allowing for the system to be commissioned and become live.

Allume can provide a free assessment for your project that will demonstrate the SAP uplift that can be gained for each flat and indicative costs.
