Assessing Your Power Needs: Essential Questions to Ask
Choosing between portable and fixed RV solar systems (or even a hybrid solution) requires some homework. Factors you’ll need to consider are current and future power requirements and, of course, budget. However, the first step is understanding how and where you camp. Which do you fall under?
While portable systems can’t usually match the performance of fixed solutions, they should meet the requirements of RVers who only need solar capabilities for a few days at a time.
Full-time road warriors.
Operators who regularly overnight in parking lots or rest areas often choose fixed solar solutions for security. Adventurous RVers who prefer remote locations may opt for portable systems if power requirements aren’t too extreme.
RVers who want all the conveniences of home will likely need to opt for a robust rooftop solar installation. These types of campers are not often able to meet power needs with even the best portable systems. However, these campers can benefit from a smaller rooftop system supplemented by a portable panel to boost charging power when required.
Also, consider the following questions to gain clarity on your energy requirements:
- How much electricity will you use? Determine the appliances, devices and amenities you intend to power in your van. Make a comprehensive list of all the electrical equipment you have onboard and their power usage to estimate your daily energy consumption and exactly how much power you’ll need from the solar panels.
- How long are your trips? Assess the duration of your vanlife adventures to understand how many days or weeks you need your solar setup to sustain your power needs off-grid.
- What is your preferred camping style? Consider your camping habits and locations. Are you more likely to park in shaded areas, where your solar panels may receive limited sunlight? Or do you prefer open spaces with ample sunlight exposure? Do you venture off the beaten path with other like-minded overland adventurers, or do you stick pretty much to established campgrounds?
- Do you know what is the best campervan solar panel? The array of available solar panels can be daunting, from traditional solar panels to foldable solar panels, portable panels, rigid solar panels, permanently mounted panels, monocrystalline solar panels to polycrystalline solar panels. Each has its benefits and costs associated with them. Rather than recommend monocrystalline solar panels, it is better to ask how many watts are needed, and how much roof space do you have. The best campervan solar panels are what works for your particular application and budget.
- Are you planning to expand your power system in the future? Anticipate how much power you will need in subsequent years. Forecasting your power requirements will help you assess the scalability of any solar network you choose.
Answering these questions, wil provide you with valuable insights into your power needs and help you make an informed decision when choosing a van solar kit.
