DMSOLAR DM 158w Monocrystalline Solar Panel (2 Pack)

We purchased a set of these for our 42 foot Catalina Mark II sailboat in June 2013 with a Morningstar 45 MPPT controller. Excellent setup and we sailed the boat to the Bahamas for the winter. Never had an issue and our three 8D batteries were always charged by noon each day. This was running all our electronics...two refrigerators...and LED lights at nights while at anchor and sailing for six months. Never an issue and great value for the price and much cheaper than competition. We purchased the MPPT controller, solar panels and connectors from Amazon and very please with the outcome.

perform as advertised, have bought 2 2packs for 4 separate installations. work great for camp trailer when coupled with a Morningstar controller.

We have had these panels for over 2.5 years and the performed well. We are using a Blue Sky MPPT controller.Recently we noted a drop in power and saw that there were problems with approx 10 cells on one of the panels. The other panel is perfect! We contacted Mr David Li and he responded immediately. The panels are guaranteed and he responded that he would replace them. We have to cover the shipping from New England to Calif. which we will do next Spring. (Health issues and now weather have prevented any work on the house). I recommend DM Solar as a viable and professional vendor of 12 volt solar systems at a fair cost.

These are great panels. I saw 150 watts out of just one of these and 305 watts out of two of them. I have been in the solar world for 4 years now and live off grid and these panels are for sure some of the best panels I have used. I love them and you will also

great panels for the price. i bought it for my first solar panel project. had to research other site to setup.used with:controller: AGPetk:  B008I0IZ7O Inverter:  B003R7EGO4 Fuse:  B008P7QJGE MC4:  B00A8TRKJW Battery:  B001VV0318 Fuse holder:  B000KIR8M0
