The popularity of solar-powered Recreational Vehicles (RVs) has grown notably as travelers turn to more sustainable power sources. This shift aligns with environmental consciousness and provides the freedom desired while one explores the outdoors. Using solar panels for RV campers allows RV enthusiasts to utilize the sun as a clean and renewable energy source that can easily power their adventures without relying on traditional campsite stops.
As with any other technological adoption, transitioning to solar power comes with challenges. In this blog, we will talk about the 12 common solar panel installation mistakes RV owners make so you can avoid them, save your money and ensure hassle-free installation.
1. Choosing the Wrong Solar Panels
The most obvious mistake people often make is buying the wrong solar panels. This might lead to either not having enough energy or having too much energy, which can lead to a waste of energy and cost. You need to determine the size of the panel you need as per your RV’s electrical needs. Check the wattage of appliances and devices you are willing to use and determine average daily usage.
If your RV has a small number of appliances and devices, an RV solar panel of nearly 400 watts would be sufficient. But, if you use more powerful appliances such as heaters or air conditioners, you might need a larger solar panel.
2. Neglecting Battery Bank Sizing
A well-sized battery bank is essential to meet your energy needs, ensuring you have sufficient power to operate independently for at least 24 hours without recharging. Common mistakes RV owners make include underestimating energy consumption, often leading to insufficient power supply. Utilizing a shunt-based battery monitor, like the Victron 712, allows for accurate measurement of electricity usage, enabling the precise determination of the required battery size and the number of solar panels needed for the RV camper’s effective recharging.
3. Poor Placement of Solar Panels
Proper placement of solar panels is a must to use the panels in the most effective way possible. A common mistake is installing panels where they can fall into the shade, significantly reducing their efficiency. Optimal placement ensures panels receive direct sunlight, as even minor shading can decrease a panel’s output, affecting the energy production of attached panels.
4. Inadequate Charge Controller Selection
When installing solar energy setups in your RV, paying attention to charge controllers is important. The charge controllers oversee the flow of electricity from panels to the battery, protecting it from overcharging.
A common mistake is choosing a controller based on cost alone, leading to the selection of units without adequate heat dissipation capabilities. Controllers with large heat sinks are preferable because they manage excess energy efficiently without relying on fans, which can fail and cause overheating. Opting for a cheaper model might save money initially but can result in long-term reliability issues and potential system failures.
5. Ignoring Energy Consumption Monitoring
Ignoring the installation of monitoring tools is a common mistake people make. RV owners are left guessing about their energy usage without monitoring tools like shunt-based battery monitors, leading to inefficient solar setups. Energy monitoring devices provide crucial data, enabling precise adjustments to install solar energy systems for optimal performance.
6. Overlooking Proper Wiring and Connections
Overlooking proper wiring and connections in an RV solar panel system can lead to significant efficiency losses and potential risks. Common mistakes include using thin or indoor wires for outdoor applications, which can degrade quickly and compromise the system’s integrity. Proper wiring is important for the safety and effectiveness of the solar setup, preventing energy loss and ensuring longevity.
7. Using Inefficient Inverters
Inverters play an important role in RV solar systems by converting DC power from the panels into AC power for everyday use. A common mistake is selecting an inverter that is either too small or inefficient for the system’s needs, leading to power loss and potential system strain. Ensuring the inverter matches the system’s capacity and energy requirements is key to efficient power conversion.
8. Failing to Account for Weather Conditions
Solar planning must account for varying weather conditions, including cloudy days and extreme temperatures, which can significantly impact energy production. Failing to prepare for these conditions often results in insufficient power supply. Incorporating weather variability into the system design ensures consistent energy availability from RV solar panels, even during less-than-ideal weather conditions.
9. Neglecting Regular Maintenance
Regular maintenance is vital for maintaining the optimal performance of a solar system. Common oversights include neglecting panel cleaning, wiring checks, and component inspections, which can lead to decreased efficiency and potential system failures. Scheduled maintenance tasks ensure the system operates at peak efficiency.
10. Ignoring Local Regulations and Permits
Sticking to local regulations and obtaining necessary permits are important steps in solar panel installation. Ignoring these legal requirements can lead to penalties and the need to modify or dismantle non-compliant installations. Proper research and compliance with local codes safeguard against legal issues.
11. Underestimating the Total Cost
Underestimating the total cost of an RV solar system installation can lead to budget shortfalls and incomplete projects. Expenses extend beyond the initial hardware purchase to include installation, maintenance, and potential upgrades. Accurate budgeting and consideration of all related costs ensure a fully functional system without unexpected financial strain.
12. Ignoring the Importance of a Backup Power Source
The reliance on a sole power source is risky. Overlooking the inclusion of a generator or alternative power solution can leave RV owners vulnerable during prolonged poor weather or technical issues.
