  2. Solar-powered pump - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_pump

    A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

    BigBelly Solar also provides companion recycling units that allow cities, parks and universities to collect single-stream or separated recyclable materials in public spaces. The first machine was installed in Vail, Colorado, in 2004. [citation needed] The city of Spokane, Washington, installed 70 of the "smart" garbage bins in 2018. [1]

    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.

    Step 3: The 14-foot wheel powers the rake and conveyor belt, even if the vessel is moving upstream. If Mr. Trash wheel does not have enough power from the current, solar panels are used to pump water onto the wheel. [4] Step 4: Trash at the top of the conveyor belt falls into a dumpster on a floating barge, which is periodically emptied.

  6. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems . A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as ...

  7. Solar controller - Wikipedia

    en.wikipedia.org/wiki/Solar_controller

    The simplest solar controller circuit uses a comparator with two temperature inputs, one at the solar panel and one at the thermal store's heat exchanger, and an output to control the pump. Commercial controllers use a microprocessor usually with a LCD display and simple user interface with a few pushbuttons.

  8. Solar-powered waste compacting bin - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_waste...

    A solar-powered waste compactor is a smart device that reads a waste bin's fill-level in real-time and triggers an automatic compaction of the waste, effectively increasing the bin's capacity by up to 5-8 times. [1] [2] The compaction mechanism runs on a battery, which is charged by the solar panel. Fully charged, the battery reserve lasts for ...
