Energy independence - 3 ways to freedom

Energy independence - 3 ways to freedom – main image

Traveling is associated primarily with the feeling of freedom and independence. For many of us, the priority is the freedom to camp on our own terms, regardless of the infrastructure and restrictions related to access to media. An important aspect here is energy freedom, i.e. the ability to obtain the power needed from alternative energy sources. Today we will tell you what options we currently have and the benefits and disadvantages of individual solutions. Of course, we invite you to exchange experiences and discuss on our fanpage!

Energy from the sun

The most popular way of obtaining energy is solar panels. The vast majority of recreational vehicle owners place them on the roofs of their campers or trailers. However, there are also mobile panels, placed near our camp or attached with suction cups/other attachments, e.g. to the glass or bodywork. This type of solutions will work, for example, when we travel in a van/small car, which becomes a "camper" only for the duration of holiday trips.

Which solar panels should you choose for a camper?

A simple solar installation consists of photovoltaic panels with a specific power (usually the panel power is 100-170W, but with technological development, more and more efficient and smaller units appear), a controller and a battery. An important element of the entire installation that is underestimated by novices and bargain hunters is the controller. MPPT (Maximum Power Point Tracking) controllers, proven and recommended by experts and users, are now standard in sensibly built installations. They are slightly more expensive than the cheapest ones on the market, but in order to obtain the highest possible output power from a specific cell under changing operating conditions, the optimal load resistance must be constantly changed - and this is what the heart, i.e. the controller, has to take care of. Of course, you also need to choose the right battery. It will be best if the gel/AGM/LiFePO4 battery does not have a capacity greater than the cell current in amperes multiplied by 10. For example: a 130 W panel with a power of 7.2 A should support a battery with a capacity of approximately 70-80 Ah.

Advantages of solar panels:

+ Relatively inexpensive investment

+ A safe solution provided that devices are professionally selected and installed

+ High efficiency on sunny days

Disadvantages of solar panels:

- Dependence on exposure/sunshine/weather

- Reduced efficiency in cold seasons and in the shade (and on hot summer days we look for places that provide shade)

- The additional weight of the installation reduces the vehicle's load capacity

Power generator for a camper

Liquid fuel power generators (gasoline/diesel) are very popular, e.g. in the USA, where virtually every larger camper is equipped with this type of device. Of course, such solutions are not common in Europe, but several manufacturers have appeared on the market offering neat mobile solutions. The most famous, iconic model of a portable generator is, for example, Honda. Its latest model, the EU32i, is currently being introduced and will soon take the camper market by storm. We are writing about this model because its predecessor's compactness, reliability, power quality and low noise level for a generator have become an unrivaled model for the entire industry. An additional benefit is the use of inverter technology, i.e. variable operating characteristics, which significantly affects both the noise generated and the efficiency of the device. Of course, Honda is not the only manufacturer of compact units, and in terms of price it is certainly not a product for the masses. There are many price and design alternatives, but the principle of operation of a compact generator is in each case the same - from liquid fuel we gain a single-phase power source capable of charging our on-board battery or powering devices with a total power of up to approx. 3 kW.

Advantages of a generator for a camper:

+ Electricity production regardless of the weather and conditions

+ Efficiency and power quality allowing even powering demanding, sensitive electronics

+ Mobility and no need to perform dedicated installations

+ Possibility to power the camper/trailer as from a traditional 230V network, including stationary air conditioning

Disadvantages of a generator for a camper:

- Price

- The noise generated may be uncomfortable for users and neighbors

Fuel cell

The so-called "fuel cell" has been on the market for years and has a loyal group of fans who consider it the best energy generator for traveling. It produces environmentally friendly electricity based on a chemical reaction that charges the on-board battery. This silent process is completely automatic. The fuel needed for the reaction is methanol. The manufacturer of the solution, EFOY, offers systems of various sizes and for various applications. Recreational vehicles, however, remain the company's main area of focus. Once the system is installed, it is virtually maintenance-free. Methanol consumption (e.g. for the EFOY 80 BT model) is 0.9 l/kWh. Fuel is taken from cartridges with a capacity of 5 or 10 liters.

Advantages of fuel cells for a camper:

+ Offered with an EFOY LiFePO4 battery, but works with most batteries

+ Compact and light solution (weight less than 7 kg)

+ Silent operation

+ Possibility of connection to a photovoltaic system

+ Maintenance-free

Disadvantages of fuel cells for a camper:

- The need to purchase dedicated fuel cartridges in the manufacturer's partner network

- High price

- Balancing power with compact versions may be difficult in larger campers (power production may be too low)

These are just 3 basic ways to survive and achieve energy independence. We are very curious about your experiences and ideas for optimizing energy consumption and obtaining it while traveling!

Travel reports
FRANCE 2010
The trip to France was supposed to be a pilgrimage along the route of French sanctuaries and it was like that, although we could admire the beautiful landscapes of, among others, French Alps, wonderful atmosphere of small towns and great quality of French (even local) roads. Day 1 - departure around 5.00 from Kielce (Skoda Superb TDI 170KM + Adria 4252) with a 4-hour rest near Złotoryja. After eating a hearty lunch, we head to the German motorway to drive the boring road through our neighbors' country at the prescribed speed (unfortunately 80 km / h). The road takes us 2 days - the first night (1050 km each) in the pouring rain in the parking lot at the gas station near Willenberg - not only we stayed there for the night - next to a trailer from the Netherlands, Belgium, Germany, Poland etc. Here the installed battery came in handy in the trailer. Day 2 - further travel on the German motorway and entry to France - we decided not to take the highways, to see a little more than noise barriers ... Drive through several charming towns where time seems to have stopped (many old stone houses, tiny churches, intimate market squares) and accommodation near the town of Gy - a small town of Bucey-les-Gy , a market and a gas station by the road, and next to it, a beautifully fenced square with a table and benches, where you can eat (next to us, a camper from France is staying here). Distance traveled - about 650 km. Day 3 - After breakfast, we go to visit Cluny , where we saw the remains of the former Benedictine abbey and took a walk through the narrow streets of the city. The next point is Ars - the city of St. John Maria Vianeya - the patron saint of parish priests. We saw the Basilica, which houses the remains of the Saint and the house where he lived and worked. In the parking lot, rest and lunch - here we also met a coach from Silesia with pilgrims. From Ars through Grenoble we went camping in Corps (20 km from La Salette). We climbed up to 1600 meters above sea level, admiring the beauty of the French Alps - also from the campground. We add another 250 km to the odometer. Day 4 - After breakfast at a small family campsite, we drive 20km further and 2000m higher - to La Salette - a mountain village in the French Alps , near Grenoble , known mainly for the apparition of the Virgin Mary in 1846 . The Mother of God appeared only once on September 19, 1846 to two shepherds: 15-year-old Melania Calvat and 11-year-old Maksymin Giraud on a mountain overlooking La Salette in the High Alps in France. At the site of the apparition (approx. 1750 m above sea level) a spring gushed out. It flows uninterruptedly from the day of the apparition until today. After conducting research, which included, inter alia, when the children were interviewed and their accounts were verified as well as the events usually connected with the apparitions (e.g. extraordinary healings), after receiving the consent of the Pope , Bishop Philibert de Bruillard , bishop of the Diocese of Grenoble announced on September 19, 1851 that the Apparition of the Virgin Mary to two shepherds on September 19, 1846 , on one of the mountains belonging to the Alpine range, located in the parish of La Salette, in the deanery of Corps , it has all the features of truthfulness, and the faithful have reasonable grounds to consider them unquestionable and certain. After September 19, 1846 , Melania, and later Maximinus, assisted by his converted father, set up crosses to mark the site of the apparition. In the spring, pilgrims set up 14 traditional Stations of the Cross , marking the path that the Beautiful Lady followed after finishing her conversation with the children. This road, resembling the letter "S", exists to this day and is located near the source. It ends with a figure representing Mary rising to heaven, with her face facing Rome , to emphasize unity with the Church. Over the years, popes have granted further privileges, both to the devotion to Our Lady of La Salette and to the Sanctuary of La Salette. So much history ... The road to the Sanctuary is narrow and winding, but the views ... are breathtaking. We participate in the Holy Mass. in Polish, because in the parking lot there was the same bus that we met in Ars. We admire the beauty of this place from two hills. Something amazing. Interesting fact: there was a camper van in the parking lot and the passengers were eating breakfast, admiring the Alps - I envied them a bit, because the view of the setting and rising sun in this place must have been amazing (but next time I will come here with a trailer). We go to the camping for dinner. We spend the afternoon at the lake, 2km from and 1000m below the campsite. Hot water and a view of the lake and the Alps again. In the evening, dinner, settlement of the camping fee (2 nights / 42euro), preparation of the caravan and car for the next road. Day 5 - early morning departure by unpaid road (thanks to this we are going through the valley among the mountains) do Avignon - The Papal Palace used to be the seat of popes in the past (from the 14th to the 18th century). Built of white stone, the stronghold is the largest Gothic building in Europe. In the complex located on the Rocher des Doms there is the so-called Little Palace, once inhabited by cardinals. Other buildings include the 13th-century Romanesque cathedral with frescoes by Simone Martini, the Ramparts, and the 12th-century Pont St-Benézet bridge. The entire complex of significant historical value was inscribed on the UNESCO World Heritage List in 1995). From here, take the motorway to Lourdes . Here, near Lidl, we meet a Pole who shows us the way to the House of the Polish Catholic Mission, where we stay for 3 nights. Place for a trailer, car, electricity connection, use of toilet and showers - 15 euro / day. The route is 700 km (of which 400 km via the motorway - the cost of a section of 40 euros). Day 6 - night and time until lunch in the rain, so we spent it in the trailer. After lunch, depart for the Sanctuary of Lourdes . Prayer and stay in the Sanctuary, at the Grotto, where pilgrims can concentrate and unhurriedly participate in religious ceremonies, lots of sick people, in wheelchairs, also during the procession with lanterns, in which we participated in the pouring rain at 9 p.m. Day 7 - continued stay in Lourdes . Sanctuary, Grotto, souvenirs, taking water from the Miraculous Spring, shopping, refueling the car and resting before the onward journey. Day 8 - we head home via Rocamadour - a 7th century sanctuary, the oldest Marian pilgrimage site in France. Navigation takes us like a fast, though very narrow path through the forest and over the cliffs ... After about 25 kilometers, it turns out that we are driving along the slope of the mountain, from where on the other side, on the other slope of the mountain, as if stuck to the rocks, is Rocamadour. Amazing view. If we were going "normally" we would not even know that such a road exists. After the adventures of navigation, which led us, among others on a 2m wide bridge, we managed to go on a route towards Poland. In the evening we are looking for a place to stay ... Dinner in a beautiful, well-kept, but empty parking lot - we do not want to spend the night here. The observation deck on the route… We see Clermont-Ferrand . We're going until 10.30 pm… We finally managed to find a parking lot and, accompanied by a Polish truck, we went to sleep. Day 9 - onward journey towards the Franco-German border, on the way we leave the road to Paray le Monial - the place of apparitions of the Sacred Heart of Jesus St. Margaret Alacoque. (From the Paray-le-Monial monastery, the cult of the Sacred Heart has spread to the whole of France and the world. Every year the temple is visited by about 300,000 pilgrims from all over the world). Lunch in a well-known place, which is Bucey-les-Gy ... After 200 km, a symbolic border and we enter the monotonous German highway. Overnight in the parking lot. Day 10 - Germany and entry to Poland, here we are looking for a place for dinner, CB recommends a restaurant at the BP station behind the "rooster". We found the "rooster" and did eat a good dinner. Then just visiting the company selling trailers (I already want to buy a bigger one) - and here again the navigation leads us on the "fast" road through the fields, where there is no asphalt! From the company, we take a different route to the highway. Approx. 23.00 we are at home. Summary: - route: 5300km, - time: 10 days, - cost: PLN 950 / person: fuel, tolls, camping, health insurance, food, drinks. Conclusions: If France is the destination, it is worth sneaking through Germany on the motorway. On site, to see something, you have to leave the highway (very expensive in France). The free roads are of very good quality and there are no major problems with driving a trailer even to small towns. The problem is with parking lots - there are a lot of parking lots right next to the road (a bay), but apart from a garbage can, there is nothing there, one car with a trailer will fit. It is also worth not waiting with refueling until the reserve lights up. And not completely trust the navigation - it's better to have the current map and correct the indications.
