Will My Motorhome's Solar Panels Work in Covered Storage?
The short answer is: no, your motorhome's solar panels will not work effectively, if at all, in covered storage. Solar panels require direct sunlight to generate electricity. Any significant obstruction, like a roof or even dense shade from trees, will drastically reduce or completely eliminate their power output.
Let's delve into the specifics and address some common questions surrounding this topic.
How Much Sunlight Do Solar Panels Need?
Solar panels are designed to capture the sun's energy. The more direct sunlight they receive, the more electricity they produce. Even diffused sunlight from a cloudy day will generate some power, but significantly less than on a bright, sunny day. In covered storage, the lack of direct sunlight renders the panels essentially useless for charging your motorhome's battery.
What Happens if My Motorhome is Partially Covered?
Even partial shading can significantly impact your solar panel's performance. Solar panels are often wired in series or parallel. If even one cell in a panel is shaded, it can impact the entire panel's output, leading to a phenomenon known as "hotspotting," which can damage the panel over time. While some minimal power might still be generated, it won't be nearly enough to effectively charge your batteries.
Can I Use Solar Panels in a Garage?
No. Garages, like covered storage, lack the necessary direct sunlight for efficient solar panel operation. The amount of light that penetrates a typical garage is far too little to make a worthwhile difference in charging.
What are My Options for Keeping My Motorhome Battery Charged in Storage?
If your motorhome is in covered storage for an extended period, you'll need alternative methods to maintain battery charge. Here are a few options:
- Battery Tender/Maintainer: These devices connect to your batteries and provide a trickle charge, preventing them from completely discharging. This is a reliable solution for short-term storage.
- Periodically Running the Engine: If your storage location allows it, starting the engine for a short time every few weeks can charge the batteries. Ensure your exhaust is properly ventilated.
- Solar Panel on a Stand: If you can place a portable solar panel in a location that receives ample sunlight outside of the storage facility, this could be a viable solution.
- Shore Power Hookup: Some storage facilities offer shore power hookups (access to an electrical outlet). If available, this is typically the most efficient way to keep your batteries charged.
How Can I Prevent Battery Damage While My Motorhome is in Storage?
Prolonged battery discharge can damage your motorhome's batteries. To prevent this:
- Disconnect the Battery: Completely disconnecting the battery is the most reliable way to prevent discharge. However, remember that this will also disable your alarm and any other systems that rely on the battery.
- Regular Battery Checks: If possible, check the battery voltage periodically using a multimeter to ensure it doesn't fall below a critical level.
In conclusion, relying on solar panels for charging your motorhome batteries while in covered storage is impractical. Consider alternative charging methods to maintain your batteries and prevent damage. Choosing the right solution will depend on the length of your storage time and the amenities available at your storage location.
