| 摘要 |
The invention relates to a photovoltaic device (PVE) which comprises a plurality of voltage-generating photovoltaic modules, said photovoltaic modules being interconnected in parallel and/or in series to generate a DC voltage (Udc*) which exceeds the voltage resistance of the photovoltaic modules and is suitable for transmitting a high voltage DC, a module field (MF+, MF-) being provided for every pole of the DC voltage (Udc*), said module field comprising a plurality (K) of photovoltaic modules which are preferably arranged in blocks and in basic structures (BS) in a potential-symmetrical fashion to a central busbar (S+, S-), and the respective module field (MF+, MF-) being encircled by a continuous ring busbar (SR) which is applied to the ground potential (EP). Preferably, every module field (MF+, MF-) is insulated from the ground potential (EP) especially insulated from the ground potential (EP) by an insulation film (IF) laid under the respective module field (MF+, MF-). |
