interesting new "demo board" - 12V solar to 400V +

[Opcom]

I swear I am not plugging this product, but it is pretty interesting, making up to 430VDC off a low voltage solar panel.

Just thinking about 2 panels, 2 boards in series, and that it might actually run a classic '100W' tube transmitter and receiver. I guess this would work best in the bright sun of the sumertime. High and Low B+.

how long will the filaments run?

Roger, KB1CMR does this all the time :-)  He is completely off-grid (and has been for many years).  He uses a lot of solar, charging batteries and using an efficient inverter.  The receiver is solid state, and Roger turns the filaments way down when receiving.  He would be a good candidate for a class E rig

for a new photovoltaic panel configuration able to increase the panel energy
produced and to simplify the photovoltaic field design and implementation.

Maybe a boost inverter to increase DC voltages but not energy.

Who needs filaments when you have solar power
