According to the manual: http://www.datamath.net/Manuals/TI-30SLR... the TI-30 SLR family has no batteries. It's powered solely by the solar panel.

If you put the calculator in a bright light does it turn on? If so, the panel might need to be replaced. Hopefully the old panel says what voltage it's rated for otherwise finding a replacement is going to be very difficult.

If it doesn't turn on, the panel may have simply detached itself from the circuit board. This would be properly repaired with a soldering iron but you might be able to get away with non-conductive tape.
