The 140 Watt RV Solar Ecomony System is the perfect system for weekend warriors or vacationers with moderate 12 volt electrical demands. The 140 Watt Solar Economy System can produce 39 to 54 amp hours per day under clear sunny skies*. This system will give you electrical independence and is a great starting point for those new to RV solar electric systems. The 140 Economy System will charge Gel, AGM or lead acid batteries commonly used in today's RV's.

The 140 Watt Solar Economy System is expandable to 280 watts! If in the future you find that you'd like more solar power. It is possible to add another 140 watt module to the existing system.

The Blue Sky Energy Sun Charger SC30 solar charge controller is a flush mounted controller that we'll install in an interior wall somewhere in your RV. The black face plate blends in nicely with RV interiors. The easy to read digital display provides battery voltage, array current (amps) and total amps produced. TheSC30 has a battery equalization mode and the display can be completely turned off at night.

Tech Notes: The owner of this Class C motor home opted to go with the 140 watt economy system so that he didn't have to worry about his batteries when the RV was not being used. The SolarTech 140 was mounted to the roof with six of our exclusive Smart Feet solar panel mounts. The panel was wired to a Blue Sky Energy SC30 Sun Charger and then to his battery bank.
