PV Plant Repowering, the Utility 50-Year Systems Model

There are two basic types of solar PV plant repowering. The first is for existing or distressed plants. The second is for extending the life of new plants at the end of their initial design life, which is projected at about 20 to 25 years. So as we concentrate on new plant repowering, what is the difference?

‘Look, Ma, No Fuel!’ … Fire-free Cooking with Solar

The cooking supply chain is being disrupted. Bounty from the sky, delivered free to the roof, drives the new cooking economy, and not the laboriously drilled, mined, transported, stored, and distributed fuel from the ground, say, kerosene or natural gas, let alone charcoal, firewood or biomass of any kind.

Solar Power: More than half of utility-scale solar photovoltaic systems track the sun through the day

The electricity generated by a solar photovoltaic (PV) system depends on the orientation and tilt of the PV panels, and in some cases, its ability to track the sun throughout the day. Because photovoltaic panels operate more efficiently when oriented directly at the sun, some systems use solar-tracking technology to increase electricity generation by rotating the panels along one or two axes.
