Solar Panel Availability

Solar Blvd has 235W panels for $152.75 so I thought I'd check on 12V panels. They don't list any in the 140W range???

Sun Elect does have 145W 12V panels for $229.

Sun Elect also lists a 200W 12V panel for $192.00. WAIT read the actual specs - this and several other Somali panels are actually 30V panels with Isc to match. This is going to require a MPPT controller to get the 200W. Not sure what to think as this panel is neither a 12V or 24V panel.

All of this continues the trend of lower 24V panels which makes them increasingly more viable with MPPT vs 12V with PWM when in the 400W panel range.

    I noticed this a few months ago. Solar Blvd stopped carrying 12V bigger than 80W. They stopped carrying 12V DIY portable kits too. Could be temporary glitch due to China's slowdown this year. Could be global trend as well, 12V are less popular with homeowners and RV is a niche market.

    200W are all 24V, this is normal. +$1.50/W for 12V panels is also normal, they've always been more expensive per watt.
  • Get the higher voltage ones. Less amps and smaller wire size. Your solar controller will convert to 12v
  • Yes it does. It makes more sense to push a lot of volts rather than amps.
