Last week I returned home from a short summer holiday which I spent in my Vanagon Camper (RV) in Łeba, a town on the Baltic Sea coast. As I own two solar panels (40 Wp each) and two gel batteries, I decided not to pay for the electrical connection and use my own power.

The prices for using the grid on the campsites in Poland are extreme. From your point of view probably it’s as cheap as everything here (10-15 PLN per day = $3-5 / day = 2.5-3.7€/day), but if you compare that price to the price of energy (0.5 PLN/kWh) it’s not worth it.

On the other hand, since I paid for the solar panels only about 900 PLN, this investment pays for itself after 60-90 days on the campsite, which is in my case equivalent to roughly 4-6 years of camping holidays. Of course that doesn’t take into account the batteries, charge controller and wiring that is not free either. (more…)
