Understanding Solar Charging
Solar charging time depends on panel wattage, battery capacity, sunlight hours, and charge controller efficiency. MPPT controllers are 20-25% more efficient than PWM controllers.
Peak sun hours vary by location and season. Summer months typically provide 5-7 hours, while winter may only offer 3-4 hours in northern latitudes.
