CONTROLLERSĪnytime you use a panel that is over 5 watts rated output, we recommend using a solar charge controller.
Typically, when 24 volts or greater is needed, solar panels may be wired in series, or we can special order solar panels that are made to deliver more DC Volts such as 24V, 36V, 48V etc. Most solar chargers are designed for 12 VDC, but we do have limited availability on a 24-volt panel. Conditions such as an overcast sky, shadows, improper mounting angle, equatorial direction or short winter days will reduce the actual solar panel output to below the rated values. Using this example, you can see that it will take at least 100 watts of solar power to recharge a 100-amp hour battery in a few days.Īlso, keep in mind that it takes direct sunshine on the surface of the panel to produce the maximum-rated power of a solar panel.
BACKUP BUDDY CHARGER FULL
After a full week, the battery will be just about fully charged. Assume you take a discharged 100-amp hour battery and charge it with a 30-watt solar panel under ideal summertime light conditions. For example, some people are trying to recharge batteries for a trolling motor, boat, RV, house, electric scooter, backwoods cabin, etc., and they want it done in very short time, usually in just a few days. We’ll attempt to answer the questions asked most often so we can save you a phone call.īefore we get started, you should know that solar power is not the cure-all for replacing spent energy. Rain or shine we get a huge number of calls about solar power each day.
