A campervan is a great way to travel and explore the United Kingdom. It provides the freedom to go wherever you want and the comfort of having a home on wheels. However, powering all the electrical appliances in a campervan can be a challenge, especially if you want to stay off-grid for an extended period. Solar panels are an excellent solution to this problem, but what size solar panel is suitable for a campervan?
Before we answer that question, it is essential to understand how solar panels work. Solar panels convert sunlight into electricity through photovoltaic cells. The amount of electricity a solar panel can produce depends on several factors such as the size of the panel, the efficiency of the cells, the angle and direction of the panel, and the amount of sunlight available. In general, the larger the panel, the more electricity it can produce.
So, what size solar panel should you get for your campervan? The answer depends on several factors such as the size of your campervan, the amount of electricity you need, and your budget. However, as a general rule, you should aim for a solar panel that can produce enough electricity to power all your appliances and recharge your batteries.
To determine the size of the solar panel you need, you need to calculate your energy requirements. Start by making a list of all the electrical appliances you will be using in your campervan, such as lights, fridge, TV, laptop, phone, and other gadgets. Then, calculate the wattage of each appliance and the number of hours you will be using them. Add up the total wattage and multiply it by the number of hours to get the total energy consumption in watt-hours (Wh) per day.
For example, if you have a 50-watt fridge that runs for ten hours a day, it will consume 500 Wh per day. If you have a 20-watt light bulb that runs for five hours a day, it will consume 100 Wh per day. If you have a 30-watt laptop that runs for two hours a day, it will consume 60 Wh per day. Adding up all these energy requirements, you get a total of 660 Wh per day.
Once you have calculated your daily energy requirements, you need to choose a solar panel that can produce enough electricity to meet your needs. A typical 100-watt solar panel can produce around 500 Wh of electricity per day, depending on the amount of sunlight available. Therefore, a 150-watt solar panel should be sufficient to meet your daily energy requirements.
However, you should also factor in the battery capacity and the charging time. A typical campervan battery has a capacity of around 100 Ah (amp-hours). If you want to recharge your battery fully in one day, you need to choose a solar panel that can produce enough electricity to recharge your battery in six hours or less. Therefore, a 150-watt solar panel would take around six hours to recharge a 100 Ah battery if the sunlight is optimal.
In conclusion, choosing the right size solar panel for your campervan depends on your energy requirements, budget, and other factors such as battery capacity and charging time. As a general rule, a 150-watt solar panel should be sufficient to power all your appliances and recharge your batteries, but you should also consider other factors such as the efficiency of the cells, the angle and direction of the panel, and the amount of sunlight available. Installing solar panels on your campervan is a great way to stay off-grid and enjoy the freedom of the open road without worrying about power supply.
