Individual solar cells are somewhat difficult to solder to. Self-adhesive metal stained-glass tape makes for the easiest soldering job--the tape holds itself in place while you solder. Use electronics solder that contains 2% silver. One side of the cell is (+), the other (-).
rain check (plural rain checks) (idiomatic) Any voucher or note from a merchant to a customer to provide an item the merchant has run out of at a later date for the item's current price, or (in a more literal sense) to provide a service at a later date.
Rainout Policy. If a regulation game (as defined by Major League Baseball) is not played and the game is rescheduled as a stand-alone game or as part of a split day/night doubleheader, your paid ticket serves as your rain check. Rain checks are valid for admission to the rescheduled game. Rain checks are eligible to be exchanged at the Citi Field Ticket Windows or by mailing tickets back to the Mets Ticket Office. Note that a regulation game has been played even if it is suspended after it becomes a regulation game.
