Local Sustainability

REhnu’s solar farms consume no water and cause minimal land disturbance.

Small ground footprint

Our solar farms will have a light footprint on the land. There is no requirement for grading or blading prior to installation. Most of the sunlight reaches the ground when the sun is high, when the shadowed area is only a third of the land area. Generator units can be installed on sloping or hilly as well as flat land, but especially sensitive habitats, such as riparian areas, will be avoided.

The installation sequence involves first building access roads covering only 10% of the land. The pedestal foundations for the generator units are set off to the side of the roads, and use no concrete and a minimal amount of steel. Power from the generators will run primarily in trenches below the roads.


To wash dust off the dish reflectors, we plan to collect and store rainwater by facing the dishes upward during downpours. Eight inches of rain annually yields 125 gallons of water per dish. From experience washing trough thermal concentrators, this is enough for a year of washing. No other water is consumed by the trackers. The cells are cooled in a sealed system by recirculated antifreeze coolant.
