Solar Smoothing can help remove the barriers to solar for businesses...

  • With limited capital​ - who may have been prohibited from considering solar before, Solar Smoothing offers an alternative solution to reduce the initial outlay.​

  • Who are safety conscious - and don’t want to take on the increased risk of have a large smoothing battery on site, Solar Smoothing is a way to reduce this risk profile.​

  • After a simple solution - without the need for an onsite battery and associated costs and ongoing maintenance, Solar Smoothing offers a way to decrease the complexity of the installation.

  • Tenants with leasing or ownership constraints - if a tenant doesn’t think they’re going to be in the property for as long as useful life of the onsite smoothing battery, Solar Smoothing offers a way to improve the payback period.
