Research has shown that the carbon payback period for solar panels is on average 1-4 years.9 This means that over a solar panel’s lifetime – typically 30 years10 – it will generate zero-carbon and zero-pollution electricity for decades after any carbon emitted during its production has been paid back.
Photovoltaic grid-connected cabinet is a distribution equipment connecting photovoltaic power station and power grid, and is the total outgoing of photovoltaic power station in the photovoltaic power generation system, and its main role is to act as the dividing point between the photovoltaic power generation system and the power grid.
Fixed installation, large space, good heat dissipation. lt can be used in solar photovoltaic power generation systems, and can also be used to convert, distribute and control electrical energy between photovoltaic inverters and transformers or loads.
If the cable from inverter to switchboard is the long one If your solar inverter is mounted close to the panels, then the long cable run will be for AC.
An inverter can reduce the output from solar PV panels but it can't get more out of them than they are delivering should the home's backup circuits require more energy than is available (e.g. a cloud passes overhead and suddenly the available power drops below what the home is currently demanding). The phrase "grid goes down" means many things.
Australian Standard AS5033 says: It is recommended that under maximum load conditions, the voltage drop from the most remote PV module in the array to the input of the PCE should not exceed 3% of the Vmp voltage (at STC) for LV PV arrays. If the cable from inverter to switchboard is the long one
