    So how good is it? I’m pondering a 400W panel but I have 2 balconies, one for the morning sun, one from around 11h…

      These systems tend toward 800 watts for about $600. Pay off is generally 4-6 years. With solar panels lasting for 30+ yrs, you gain a degree of power independence and a rough income of $100-200/yr.

      1200w setups are legal in Utah, so you may be able to get one of their systems in the states. Ecoflow has one called the ecoflow stream..

      Since the limit is 1200w in utah, what some people are doing is deploying 1200w into the active circuit, with another 1200w going fully into a battery. Since only one 1200w system is in use at a time, this is apparently allowed under the law.

        In Germany you can get an 800W system, so two solar panels, a converter and cables for 250€. You usually need some sort of attachment as well, which is another 50€ or so. They are surprisingly cheap.

        I know Germany have relaxed their laws but I’m in France, guess I have to wait until the “revolution” comes here.
