Within molten salt applications, valves are mainly pneumatic operated globe-style or angle-style control valves with buttwelded end connections and extended bonnets.
These modules consist of multiple strings of solar cells, wired in series (positive to negative), and are mounted in an aluminum frame. Each solar cell is capable of producing 0.5 volts. A 36-cell module is rated to produce 18 volts. Larger modules will have 60 or 72 cells in a frame. The size or area of the cell determines the amount of amperage.

Solar cells are connected to the receiver of the produced current with the use of electrical contacts. Unless these contacts are made extremely thin, the cell won''t be able to harness any sunlight. Once these electrical contacts are placed on the cells'' exposed areas, thin strips of tin-coated copper are placed between cells.

Each solar cell is capable of producing 0.5 volts. A 36-cell module is rated to produce 18 volts. Larger modules will have 60 or 72 cells in a frame. The size or area of the cell determines the amount of amperage. The larger the cell, the higher the amperage. Figure 1. A 12 volt bilge pump works very well in a bucket wired to a solar module.
Solar modules, though similar in design (silicon crystalline-type) will vary by size and power produced. Readers are encouraged to refer to the Extension factsheet, “Demystifying the Solar Module” (AZ1701) for information about solar PV modules. Simple systems have fewer components, but are limited to providing energy when the sun is shining.
