Electricity & EDF & Solar panels rant

You can cath a sideway view of my beautiful bay window... but also the montain of electrical cables. Electricity is something that I have difficutly understanding and no wish to understand but I had to be able to understand a minimum to chat to the electrician. Should have paid attention to those lessons in physics at school....nevermind.
Anyways, so the place was more or less rewired wherever necessary and now it is up to standard. We went from a EDF TRI-phased to MONO-phased contract... that was a long and painful conversation with EDF and the electrician for me. Still not sure how it works but the upshot is that now you can use all the electrical point (washing machine + toaster+ kettle+ lights+ heating etc) without having the lot cutting off which can happen when you use TRI-phased system (not good for holiday rental accommodation). This also means that your Kw contract in Mono should be be less than in TRI. And therefore your contract should cost a bit less. However, EDF just annonced that they are gonna raise the cost of electricity by 20% over the next 3 years. Oh dear.... Maybe should have gone with solar panels... Solar panels would have been good but:
1. The cost is really high. I know it should be looked at as an investement but I did not have the budget to invest... 15000 to 20000 euros (minimum) would give you about 2.2 kw which would have been just enough to power a toaster and the hot water system. That is an expensive shower! So it was out of the question.
2. The use of the house is seasonal so what to do with the electricity not used. You can sell it back to EDF. I think they buy it at a preferential rate now but only for the next few years. Also I understnad that it is considered as a revenue and therefore taxed and VAT- ed. So a bit more paper work...
3. You can get some financial help and tax credit with solar pannel installation. But I am not a french resident so a bit pointless for me.
4. A lot of eco-friendly solution is cost on self- built basis. So it is fine if you are a builder yourself but when like me you have to pay for installation, it become costly....
5. You have to factor in the region you live in. Great for anyone living south of Aix en Provence but not sure about Burgundy where the summer is quite short....(but still very nice don't get me wrong, potential renters!)
6. It is ugly! What is the point of having charming reclaimed hand made local roof tiles if you are going to cover it with metres of dark metallic pannels. It is possible to stick them on the ground but you need the space, and built trenches for the cables etc....

In the end, I think solar energy is great but it has to fit your purpose. If you live all year round in a house where you collect rain water, self recycle, resuse, where you have a huge garden (to hide your panels somewhere), where you are happy with maximum 17 degre living temperature in winter, where you use low volatage bulbs (and become blind) and where the sun shines 300 days/365; and where you have 20.000 euros plus to invest: well, fine. But I am sorry but for our project it really did not make sense financially, pratically and esthetically....
