A 300W solar panel can charge a 100ah battery in 4 to 5 hours. This is possible if the sky is clear and the sun is out. Cloudy skies, shading and rain will lead to slower battery charge times. Some lithium batteries claim to have an 85% DOD, while others are 90%. Which is it really? The depth discharge rate varies.
A 300 watt solar panel can charge a battery as shown in the wiring diagram. However, the passage does not provide details about the load side of the system or charging the battery from other sources like shore power or the alternator. For that information, please refer to our post on campervan wiring.
As long as your 300 watt solar panel and battery are matched, either 12V or 24V, you can use a PWM charge controller. An MPPT controller can provide more power, but the increase -17% to 20% – is not enough to justify the cost, at least for a small system. In many cases your solar system will not run at maximum voltage.
A 300 watt solar panel can produce approximately how much power depends on various factors such as time of year, weather, location, and the type of charge controller you install. Here’s an idea of what you might expect to get on an average day of 4 peak hours of sun with an MPPT controller.
