Cleaning and maintaining RV solar panels
The solar panels are your sleek energy harvesters transforming sunlight into power for your RV. To keep them operating at peak efficiency, a bit of TLC is in order. Over time, dust, sand, and debris can impact the efficiency of your solar setup.
How do I clean my solar panels?
Choosing a Go Power Solar RV Kit helps to keep maintenance at a minimum. However, you can benefit from performance gains by regularly cleaning the solar panels. How often you will need to clean them depends on the circumstances. The reality is that wind will blow off loose particles and dust, so when driving, there is an inherent cleaning effect. The same applies to rain; it washes down the panels, rinsing away dirt that may have built up.
Step-by-step guide for cleaning your solar panels
1. Turning off the system is only required if you disconnect any of the wiring.
2. Clean the solar panels as needed on a bi-annual or monthly basis. Use water and a soft sponge or cloth. A mild, non-abrasive cleanser can be used for more stubborn residue. Rinse well.
3. You may have to clean the panels more frequently during drier months. A pressure washer is not recommended.
4. Use a soft brush to remove snow during the cold months to keep producing power.
5. Clean seasonal substances like pollen or leaves and other tree droppings that may get stuck on the panels.
6. Watch out for bird droppings and clean them off as soon as possible.
7. Check all wire connections to ensure all are still securely attached.
Do flexible panels require different care?
The surface of flexible panels is more delicate than that of rigid panels. It’s advisable to proceed without applying much force. The panels should be cleaned using soap and water, wiping carefully and without using abrasive materials. Do not use scouring pads or other materials that could scrape the surface. Rubbing alcohol can be used to remove tougher grease, sap, etc. Whenever in doubt, consult the manufacturer’s recommendations for cleaning and maintenance to comply with warranty provisions.
Solar panel maintenance – Tips for being proactive
Solar panel care extends beyond cleaning. The structural integrity of the installation and the electrical connections will need to be checked periodically. Are there any cracks, missing or broken hardware, or other potential problems?
- Check all roof penetrations and replace sealant as required
- Make sure mounting hardware is securely fastened to the vehicle and panels
- Watch for any connections that may have come loose due to vibrations
By implementing these cleaning and maintenance practices, you’ll ensure that your solar panels continue to harvest the sun’s energy efficiently, providing sustainable power for your RV adventures.
Battery maintenance – Peak performance and extended lifespan
Routine inspections also help with preserving the longevity of RV batteries. Keep an eye out for any indications of corrosion or leaks, and verify that the connections remain clean and securely tightened. Regular monitoring of your batteries’ charge level and voltage will help to detect any potential issues ahead of time.
Watch out for differences between battery types
Lead Acid batteries are likely the stock batteries your RV or trailer came with. Lead acid batteries are the most inexpensive batteries on the market today. They require a vented location, regular maintenance, and are one of the older battery technologies available.
AGM batteries are sealed, do not spill or vent gas, and require very little maintenance. AGM batteries also charge quickly and are more resistant to low temperatures. They are, however, sensitive to overcharging.
Lithium batteries require virtually no maintenance. Advanced Lithium batteries will come with an integrated battery management system. Even though the high performance and long lifecycle come with a higher price tag, many RVers are in love with this type of battery.
Comprehensive battery maintenance checklist
1. Regular Inspections: Conduct routine checks of your batteries to detect any signs of corrosion, leaks, or physical damage.
2. Terminal Maintenance: Ensure that the connections at the terminals are securely tightened. Use a solution of baking soda and water or a wire brush to clean any corrosion. Disconnect the cables, clean the terminals and cable ends, and then reconnect them.
3. Voltage Monitoring: Consistently monitor the voltage of your batteries with a multimeter. This practice helps in identifying potential issues with either the charging system or the batteries themselves. Periodically, perform a capacity test to ascertain the batteries' ability to hold a charge.
4. Charging Best Practices: Regularly charge your batteries, especially if the vehicle is not in use. Consider investing in a battery maintainer to sustain optimal charge levels during periods of storage.
5. Water Level Check (for Lead-Acid Batteries): If you use lead-acid batteries, routinely inspect water levels. Add distilled water as necessary.
6. Timely Replacement: Recognize that batteries have a finite lifespan. If you observe a significant decline in performance or if your batteries are aging, contemplate replacing them.
7. Professional Evaluation: If you are not sure about the condition of your batteries or if an issue persists, seek out a professional service technician for a comprehensive inspection.
Regular checks and consistent maintenance can dramatically extend battery life, in many cases, by 4-5 years. Solar power is a great way to frequently recharge your batteries and contribute to their health.
Inverter and charge controller maintenance
Charge Controllers manage the charging process of your van’s batteries. As an electronic device, they should only require minimal maintenance, often limited to accumulated dust or dirt. They generate heat during operation, so adequate air circulation is required.
Regularly check for software updates with bug fixes and improved functionality to keep your charge controller humming and your batteries safe.
Inverters transform DC from the batteries into AC power. Follow these recommendations for improved efficiency:
1. Check for loose connections, signs of overheating, or physical damage to the inverter.
2. Clean dust and debris to avoid blocked vents, as those cause overheating and reduce efficiency.
3. Make sure there are no obstructions to inverters with cooling fans. A well-ventilated inverter works better and lasts longer.
4. Regularly test the overload protection mechanisms of the inverter to ensure it shuts down safely. Check and test any alarm systems or warning indicators on the inverter for continued safe operation.
System health in extreme temperatures
In extremely hot weather, components can overheat, with a detrimental effect on performance. Ensure airflow around the solar panels and keep the batteries well ventilated and in the shade. It may be necessary to open access panels to keep the inverter cool.
For winterizing, proceed as follows:
- If you are removing the batteries for storage, then cover the solar panels with something opaque. Once in the dark, they are powered off and will wait patiently until they are uncovered in the spring after the batteries are re-installed.
- If you have lead, AGM, or heated Lithium batteries and are not removing them from the vehicle, then leave the solar system in place and simply ensure the panels are not covered in snow. If you have non-heated lithium batteries (and are in a place that drops below freezing for an extended period), fully charge and disconnect them. Preferably store them inside, away from extreme cold.
