Not exact matches

Generating electricity from solar - thermal energy, however, usually requires a large - scale system, with an array of mirrors that reflect and concentrate sunlight onto tanks or pipes filled with water or other liquids.

The low end of this temperature range can be supported by existing molten nitrate salt power tower systems while the high end temperatures will require advanced molten - salt or particle - based concentrating solar thermal (CST) systems currently under development.

Accurate long - term scientific predictions require conserved quantities: in solar system dynamics this conserved quantity is dynamical energy; in Hansen's climate - change theory it is thermal energy.

All but 18 states have some utility - scale solar PV capacity, but only three states (California, Arizona, and Nevada) have utility - scale solar thermal resources, as these systems often require large, contiguous tracts of land in arid environments.

But capital costs are the real show - stoppers: for photovoltaics, at $ 3 / peak watt current prices (solar thermal systems are roughly the same), even in an ideal location, 2000 TWh / yr requires about 1 TW peak capacity, or $ 3 trillion capital investment.

Having built a greenhouse housing two aquaponic systems, Dependent on thermal mass to warm them through the nights When temps dipped into single digits, Realizing some supplemental heat was required to sustain them, I built a solar water heater to collect warmth from the sun.

The supply is unreliable, although more consistent than wind generation which is notoriously unreliable and thermal, nuclear, or hydro power (if available) is required to carry sufficient reserve in the grid system to compensate for any changes in solar plant output due to any changes in sunlight during the day.

Solar thermal systems seem to require a bit more attention — its not they they are high maintenance, but there are a few things you need to check once in a while.
