We purchased a battery and solar system during the 2019 Toronto boat show in January. It completely changed our boating experience. Before installing 220W system we could only be on the water for 2 days before our batteries were too low to keep up with both fridges and other power needs. After assessing our needs and usage Patrick had recommended a system and we made the leap. We can now spend as long as we want at anchor and are not constrained by our lack of an onboard generator. This previous summer we spent 5 consecutive days anchored in one spot without starting an engine or generator. Our batteries were always in good health and there was no worry of fridges spoiling food or warm drinks! It has completely ridden the worries of batteries dropping too low and we will be installing solar from SunTech solar on the next boat when it is time to upgrade!
