Here's the format that i think would work best, just make it one line and have the following:
Stv, DATA; Stc, DATA; Stt, DATA; Sbv, DATA; Sbc, DATA; Sbt, DATA; S1v, DATA; S1c, DATA; S1t, DATA; S2v, DATA; S2c, DATA; S2t, DATA; S3v, DATA; S3c, DATA; S3t, DATA; S4v, DATA; S4c, DATA; S4t, DATA; Bt, DATA; Bv, DATA; Bc, DATA;
All data in numbers with decimals
Stv = Solar Panel Top voltage
Stc = Solar Panel Top current
Stt = Solar Panel Top temperature
Sbv = Solar Panel Bottom voltage
Sbc = Solar Panel Bottom current
Sbt = Solar Panel Bottom temperature
S1v = Solar Panel 1 voltage
S1c = Solar Panel 1 current
S1t = Solar Panel 1 temperature
S2v = Solar Panel 2 voltage
S2c = Solar Panel 2 current
S2t = Solar Panel 2 temperature
S3v = Solar Panel 3 voltage
S3c = Solar Panel 3 current
S3t = Solar Panel 3 temperature
S4v = Solar Panel 4 voltage
S4c = Solar Panel 4 current
S4t = Solar Panel 4 temperature
Bt = Battery temperature
Bv = Battery voltage
Bc = Battery current
