Elektrownie balkonowe 2000 W – duże zestawy do 2 000 Wp

“2000 watts” in a product title almost always refers to the panel output, i.e. four panels of around 450 to 500 Wp each. Even so, no more than 800 watts are fed in, because that limit applies to the inverter or the output to the home circuit. Some kits include a larger inverter that is throttled to 800 watts for operation as a plug-in solar device – check the datasheet to see whether and how this is set.

The advantage of large panel areas: you reach 800 watts earlier in the morning, hold it longer into the afternoon and get more yield on cloudy days. With an east-west split, production is spread more evenly across the day.

Four panels need space – around 7 to 8 square metres. That's rarely feasible on a typical balcony railing; gardens, flat roofs, garages or carports make more sense. Without a battery, self-consumption only rises to a limited extent, because more power is clipped or exported at midday. With a battery, surpluses can be shifted into the evening.

Registering in the Market Master Data Register is enough here too, provided panel output and feed-in output stay within the limits. For mounting frames on garages, on façades or in conservation areas, local building or design regulations may also apply. If in doubt, ask your local council before installing larger frames.

With 2,000 Wp kits, always work out the price per Wp and check which mounting hardware is included – especially with garden and flat-roof kits, the mounting frame accounts for a large part of the price. Also check which inverter is fitted and whether it's limited to 800 watts out of the box. Kits with batteries have their own comparison page, because price and benefit work out quite differently there.
