2. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   A PV solar-powered pump system has three main parts - one or more solar panels, a controller, and a pump.The solar panels make up most (up to 80%) of the system's cost. [citation needed] The size of the PV system is directly dependent on the size of the pump, the amount of water that is required, and the solar irradiance available.

3. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

4. Solar-assisted heat pump - Wikipedia

   en.wikipedia.org/wiki/Solar-assisted_heat_pump

   The operating conditions' optimization of this system is the main challenge, because there are two opposing trends of the performance of the two sub-systems: by way of example, decreasing the evaporation temperature of the working fluid increases the thermal efficiency of the solar panel but decreases the performance of the heat pump, and consequently the COP.

7. Solar-powered Stirling engine - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_Stirling_engine

   NASA patented a type of solar-powered Stirling engine on August 3, 1976. It used solar energy to pump water from a river, lake, or stream. [1] The purpose of this apparatus is to “provide a low-cost, low-technology pump having particular utility in irrigation systems employed in underdeveloped arid regions of the earth…[using] the basic principles of the Stirling heat engine“.
