I'm surprised you think of this as harassment, but I can understand why you wouldn't want your guests to be hassled. Is it actually that you just thought they were a bit peculiar, and had a laugh about them, and it's only when they started speaking to the people you lent your house to that it became a problem? Anyway, I echo what the others suggest. You don't say where your house is, but I imagine it's in the country. If you're only there rarely then you will be a source of fascination for your neighbours, and they will want to know about you. They will find excuses to do this. I think you will have to be used to being a bit like the penguin pool at the zoo, being a spectacle without wanting to be! Indeed it may be that you are considered a bit weird because every time one of your neighbours tries to be friendly/neighbourly/asks a question about access you scuttle upstairs and hide like a frightened rabbit! As others have said, you're the foreigners, so it behooves you to "fit in". You're only there 8 weeks of the year. People are asking you reasonable questions as your neighbours - they'll have difficulty catching you if you're there so rarely - and trying to help you, with the EDF info. Even if you don't like people, or French people, grit your teeth and be prepared to improve your French by speaking to these people and, if you can bear it, invite them for aperos.
