Sharing rooftop solar to apartments

The SolShare solution is simple and affordable, paving the way for millions of apartments to gain access to solar and achieving net zero. The SolShare is the world’s only hardware for connecting multiple apartments to a single rooftop solar system. This allows apartment residents across the world to enjoy the same benefits of rooftop solar that individual homes have for years: reduced electricity bills and lower carbon footprints.

The SolShare can be installed on any low to medium-rise apartment building, with major markets being Social Housing Providers, Property Developers, and Asset Owners & Managers.

The SolShare’s effectiveness can be verified and measured via the monitoring of solar distribution. This can be used to calculate each apartment’s energy savings, CO2 reductions, and money saved. Typically, apartment residents will save up to 40% on their energy bills and, depending on the size of the system, stop between 15-100 tonnes of CO2 from entering the atmosphere each year.

Allume Energy currently have systems that are supplying nearly 4GWh of electricity per year to over 1,250 apartments. These systems are stopping over 3,000 tonnes of CO2 from entering the atmosphere every year.

Launching the product in late 2020, Allume Energy are just the start of their journey. They have recently expanded to the UK and US, and have contracted sales that will treble installations: over 3,000 apartments being supplied with 13GWh of electricity and stopping 10,000 tonnes of CO2 from entering the atmosphere.

A typical SolShare system can cost £1,000 – £1,500 per apartment. That is for the entire system: panels; inverter; SolShare; labour etc.

Payback can be anywhere between 3-6 years depending on a few factors including system cost and the percentage of energy offset by the solar.

The system is built to last 20-25 years and therefore provides an ROI of 4-8 times the initial investment.
