Many RVers rely on solar panels to power their motorhomes, providing a convenient and sustainable energy source. But what happens when your motorhome is in covered storage? Will your solar panels still generate enough power to keep your batteries topped up? The simple answer is: it depends. Let's explore the factors influencing solar panel performance in covered storage.
How Much Sunlight Do Solar Panels Need?
Solar panels require direct sunlight to generate electricity. The angle of the sun, cloud cover, and even the time of day significantly impact their output. While some light penetration may occur through certain types of coverings, it's unlikely to be sufficient for significant power generation. Think of it this way: if you can't comfortably read a book in the shade of your storage facility, your solar panels probably aren't producing much energy either.
What Types of Covered Storage Affect Solar Panel Performance?
The type of cover significantly impacts solar panel efficiency:
-
Open-sided sheds or carports: These structures offer partial shade, allowing some sunlight to reach the panels. While not ideal, you might still see some limited power generation, especially if the panels are positioned to catch the most direct sunlight available.
-
Completely enclosed storage units: These offer virtually no sunlight penetration, rendering your solar panels largely ineffective. You'll likely find that your batteries drain without sufficient external power input.
-
Storage with translucent roofing: Some storage facilities utilize translucent roofing materials that allow diffused light to pass through. While this offers more sunlight than completely enclosed structures, it won't provide the intense direct sunlight needed for optimal solar panel performance. The amount of power generated will be considerably reduced.
Can I Still Use My Solar Panels in Covered Storage?
The answer depends on your needs and the type of storage:
-
Minimal energy needs: If your only concern is maintaining a trickle charge to prevent deep discharge of your battery, you might get away with it in an open-sided shed. However, this is unlikely to keep up with the drain from things like clocks and alarm systems.
-
Significant energy needs: If you need to power appliances or maintain a comfortable temperature inside your RV while in storage, you definitely won't get enough power from solar panels in covered storage. In this scenario, you'll likely need to disconnect the panels or use an external power source.
How Can I Maintain My Motorhome's Batteries While in Covered Storage?
Several options exist for maintaining your batteries:
-
Disconnect the batteries: This is the simplest approach. Disconnecting the batteries prevents any drain, ensuring they remain fully charged until your next trip.
-
Use a battery maintainer: A battery maintainer, also known as a trickle charger, provides a small, consistent charge to prevent deep discharge.
-
Connect to shore power: If your storage facility offers electrical hookups, connecting to shore power is the most effective way to maintain your batteries.
What About Solar Panels Designed for Low-Light Conditions?
While some solar panels are marketed as being more efficient in low-light conditions, they won't work effectively in complete darkness or under heavy shading. They'll produce significantly less power than in direct sunlight.
