I bought two small solar panels about 15 years ago for use in a preparedness bug out bag when I lived in the city..they are small …never used… paid 100 dollars each…. OUCH…
they're both 12v and 10 watts each…
I just found them today stored in a warehouse since the mid 2000’s … work good…
since I have a 24V system I would like series them , and hook up to the the main battery bank to simply add to the overall power it receives..
can I simply straight wire them to the main pos / neg bussbars… ( but before the shunt ) ) and let them add their power to the main bank..
I actually feel sorry for them...neglected in total darkness for many years.. an sad fate for a solar panel…
I have no other need for them… that I can think of…
im sure there will be snickers at their size , but at 20 watts x .65- .70% production year round = 14 Wh x 5 +/- sun hours a day x 30 days a month X 12 months = approx 24kwh extra power stored energy per year…That would run the lights /cell phones in the RV a very long time..
what say you.? ...how would anyone of you put them to use…?
