Topoint 190W JTM190-72M Monocrystalline solar panel
The Topoint 190 Watt Monocrystalline solar panel is unique because it's size, perfect for RV's with 2 batteries. This much power is near the top of what is appropriate for 2 battery systems so you can expect to see a full charge early in the day when it's shining and a couple of days in the worst weather.
These 190 Watt panels are better than mail order panels because 150 Watt (low voltage/PWM) panels are about as big as you can ship, here you get 190 (high voltage/MPPT) watts from a single panel. When you want to go big, this is the way.
These panels REQUIRE the use of the proper MPPT charge controller.
Why is this panel so great?
- High voltage/MPPT style systems are superior to low voltage/PWM systems.
-The higher voltage of the panel reduces losses through the wire, allowing the use of longer wire.
-Industrial grade panels are better and less expensive than "low voltage" panels.
-190 watts is a great size, it's always better to get 1 bigger panel instead of 2 smaller ones.
-Because the panel cost is so much lower, we can get a much better (and more expensive) MPPT charge controller and end up with top notch system at a bargain price.
- UL, ETL, and TUV certified.

The Topoint panel is a great size for up to 300 square feet and can produce enough power for the essentials even in low light conditions. Expect 7-11 Amps on the best sunny days, down to maybe 1-5 amps in the worst Oregon winter.
What will this actually power? If the panel sees sun you can run lights, computers, phone, small fans or pumps, and maybe a little TV every day. The occasional tool, coffee pot or microwave if your batteries can push it. Very efficient refrigerators are possible but higher loads like air conditioning are not likely. In the winter clouds this will drop down to around 5 hours of L.E.D. lights/ computer/ phone per day .
If you need electricity, you need solar. This panel is perfect for backup emergency power and is small enough to store and move by hand. Generators are just expensive chunks of metal if fuel is not readily available but with solar you get reliable, easy, power, day after day, for years. With a kit from Lightharvest Solar you can't go wrong.
