    WE’RE USING THIS SOLAR PANEL ON OUR 7 TON TRUCK FOR UTILITY POWER , BATTERY CHARGING, LIGHTING AND EVEN A COFFEE MAKER.

    THANK YOU.

  2. Mike Jensen Verified Buyer –

    put on my cargo trailer conversion. never need to charge battery or use generator!

  3. Thomas Innis Verified Buyer –

    Cannot mount to flat surface as-is. Control module protrudes beyond frame so you have to build or buy additional brackets to be able to mount this.

    April 11th 2025 – I have updated my review to 3 stars as the panel does work. I would like it to see it come with some minimal bracketry but…
    The panel does seem to be working but required careful drilling of the frame to be mountable.

  4. Wopsy Verified Buyer –

    I have not plugged in my electric charger since I installed this solar charger on my golf cart. This unit has no trouble keeping up.

  5. Dale P. Verified Buyer –

    The Suner Power SP-20W-M PRO solar battery charger with MPPT charge controller is a great little 20W (20V, 1A) charger that works as specified. In bright sun it delivered a little over 1A when connected to my Prius AGM auxiliary battery. We don’t drive much, so I plan to use this charger to top off the battery every month. When I disconnected the charger from my car battery, I could see that the open circuit voltage was about 21v as specified for a second until the unit shut down. I don’t have the test equipment to test the MPPT function. The controller can be set for use with standard 12V batteries, 12V AGM or12V lithium-ion batteries. This includes lifepo4 batteries, but all lithium batteries must have a built-in battery management system). The charge controller has LED indicators for reverse connection and State of Charge, The unit came with nice long leads and two options for connecting to a battery. The 4 page User Manual was complete, although some of the wording was “broken” English and required a little interpretation on my part. It includes a basic testing procedure for those who might not know how to do it. I’ve only run this for a couple hours so I can’t comment on reliability. The manual states the unit comes with an “extended 12 months warranty”. Support is by email and they claim 12 hour response.

  7. Timothy Verified Buyer –

    This solar charger works great to keep the battery on the boat chargeds up when not in use. I really like that it shows you how much charge the battery has.

  8. Ralph Mason Clark Verified Buyer –

    Works well charging a 12 volt battery. No issues and since October the 12V battery has always worked when needed.
