Based on this contextual analysis, five models of community solar that will work in the current context are showcased here. These models are: 

  • Repower Shoalhaven (also known as The Difference Incubator model) – This small-scale community solarfarm model uses a proprietary limited company Special Purpose Vehicle (SPV) legal structure to enable up to 50 community members to co-invest in a project. REPower Shoalhaven is a successful example of this model. 
  • ClearSky Solar Investments (CSSI) model - CSSI is effectively a peer-to-peer lending broker. An end user is identified who wants to benefit from solar power but, for whatever reason, does not want to make a capital purchase. ClearSky investors lend the money and have their capital repaid with interest via by selling the electricity generated by the system at an agreed price over an agreed term. At the end of the term the panels become the property of the end-user. 
  • Embark/Sydney Renewable Power Company (SRPC) model - Embark's mid-sized community solarfarm model uses an unlisted public company legal structure to enable medium-to-large numbers of community members to co-invest in a project. 
  • CORENA’s Donation Revolving Fund model – Donation-based models such as CORENA’s use voluntary contributions of any amount from citizens to provide a zero interest loan to install solar PV on and undertaken energy efficiency at a community organisation’s building. The loan repayments are used to fund even more community energy projects. 
  • Darebin Solar Savers (Moreland Energy Foundation Ltd) low-income rates model – this model supporting solar PV uptake in the residential sector, particularly households that cannot afford to put solar on their roof through upfront payments. It does this through utilisation of Council rates scheme to support financing and a community organisation providing trusted brokering. 







Solar Savers 


Allowing many people to participate in a community solar project. 

Develop community energy projects local people can benefit from. 

People without a suitable roof get the benefits of solar PV. 

Increase uptake of renewables, see benefits go to good organisations. 

Low income household access to solar PV.
