It is needed to clean the pipe that is connected to the upstream pressure sensor.

We found that due to solar’s intermittency, supplying large fractions of electricity demand requires a fair degree of “overbuilding” (solar panel capacity well in excess of total electricity demand), as well as a fair amount of storage. For a single family home where power demand never exceeds 10 kilowatts (and most of the time is below 2 kilowatts), supplying 80% of annual electricity consumption requires at least 13.7 kilowatts of solar panels, and 40 kilowatt-hours of storage. And supplying even higher fractions of electricity demand — 90%, 95%, 99% — the infrastructure requirements gets even more burdensome. Going from 80 to 90% of electricity supplied requires nearly doubling solar panel capacity
Brașov (scor: 80,9), Sibiu (80,8) și Oradea (80,6) conduc topul orașelor cu cel mai ridicat grad de mulțumire al locuitorilor, cu scoruri de peste 80 din 100, potrivit datelor colectate de Storia
La polul opus, cele mai scăzute niveluri de satisfacție au fost înregistrate în Ploiești (63,6), Alexandria (65,1) și Tulcea (65,7). Bucureștiul se clasează abia pe locul 24, cu un scor de 71,8, în timp ce Cluj-Napoca ocupă locul 5, cu un scor de 78,7.
