If you just need the energy for the pool, a small setup without battery is all you need. Saves you half the price. Panels and inverters are around 900€ in Germany. Putting a battery on it makes another 1,200€ and it makes sense only, if you need power in the evening.
Don’t know if that helps you - here in Europe it doesn’t look better. In all countries you can choose between the crazy, the stupid and the as-always. I‘m afraid the politics machine transforms you in one of those or scares away the motivated.
