Solar is a good idea for gas- and diesel-powered ICE cars and bikes as well

| filed under: , , , , , , , , ,

Talking about solar, I installed solar panels onto my BMW sedan and motorcycle in order to just trickle charge and condition the batteries of vehicles I didn't use every day.

Pulsetech SP-2 SolarPulse 2WT Maintainer

I live in an apartment building and work from home so my 2001 BMW 530i and my 1995 BMW K1100LT sat in the sun a lot, allowing always on services to drain batteries when I just wasn't driving. So, while they lived in an outdoor parking lot and on the street, their batteries would be trickle-charged and conditioned. Topped-up!

It's a perfect hack, especially if your vehicle has a lot of ghost/parasite battery drain over time from just standby, always-on, services. I had the Pulsetech SP-2 SolarPulse 2WT Maintainer, but I guess I would recommend the SP-3 now, based on availability. 

I couldn't find the version that I used on my bike, the SP-2, but here's a link to the SP-3 SolarPulse 12V Battery Solar Charger Maintainer, 3W, on Amazon. Thanks to Khanh Nguyen of EUBMW for the beautiful installation, which I wanted to be perfect and permanently and durably connected to the battery.

And, yes, we drilled into the top case. It was installed, installed. 

Restores and maintains the normal loss of 12-volt lead-acid battery power on seldom used outdoor vehicles and equipmentHigher efficiency, higher quality crystalline silicone cells pack more power per square inchLonger life than standard amorphous "thin film" solar cellsSturdier smaller sized solar panel

  • Works on all 12-volt lead-acid batteries including VRLA, AGM gel and flooded cell
  • Crystalline silicon photo-voltaic cells maximize solar-toenergy conversion in smallest possible footprint
  • Restores and maintains normal loss of battery power on seldom-used vehicles and equipment stored outside
  • Patented Pulse Technology keeps battery plates clean of damaging sulfate deposits extending battery life up to 3 times
  • Maintains batteries indefinitely without danger of overcharging or overheating
