Unlock the hidden value in your property

On-site solar generation provides an immediate and permanent reduction in a facility’s energy costs and CO2/GHG footprint while also delivering an attractive ROI and substantial tax benefits.

Why Solar? — Cap Rate Effect
Solar provides immediate and sustained energy cost savings, resulting in a permanent decrease in OpEx and a permanent increase in NOI. This translates into an increase in asset value for income properties on day one.

Why Solar? — CO2/GHG Reduction
Solar provides an immediate and sustained reduction in building CO2 and Greenhouse Gas emissions. Solar significantly outperforms green roofs in terms of energy savings and GHG reductions per square foot.

Why Solar? — Submetering Revenue
Unit submetering creates additional revenue streams from solar on residential and commercial income properties.
