Hi, I have two solar panels rated at 315watts that I assumed when buying were 12v panels and have wired them in series for my 24v off-grid system. They have a VOC of 39v and VMP of 32.5. Other panels I''ve bought with similar ratings as 24v panels I''ve wired in parallel. Can someone tell me which is correct? Thanks.

What is solar Kilowatt Peak Power (kWp)? Kilowatt Peak Power (kWp) is a measurement most typically found when measuring solar power output. It is the metric used to display solar panel peak power. For example, a 1 kWp solar panel will produce up to 1 kW of electricity under Standard Test Conditions (STC).
The Maximum Power Current rating (Imp) on a solar panel indicates the amount of current produced by a solar panel when it''s operating at its maximum power output (Pmax) under ideal conditions. Solar panels are classified by their nominal voltages (e.g., 12 Volts or 24 Volts), but these voltages are only used as a reference for designing

They have a VOC of 39v and VMP of 32.5.
The higher a solar panel is rated, the greater the nominal power it will produce. A solar system rated at 4kWp will produce a 4kW (4000W) power output in ideal conditions. Theoretically, the solar panel output would be 4kWh of solar power after one hour. Because conditions vary constantly, it is rare for a solar system to deliver peak power output.
What are the pros if my solar input voltage is below the nominal voltage of of my inverter... can i damage my inverter if i am to add more panels to achieve nominal voltage and to achieve this nominal voltage i surpass the rated solar power .

The nominal power is the nameplate capacity of photovoltaic (PV) devices, such as solar cells, modules and systems, and is determined by measuring the electric current and voltage in a circuit, while varying the resistance under precisely defined conditions. The nominal power is important for designing an installation in order to correctly dimension its cabling and converters.
Nominal power (or peak power) is the nameplate capacity of photovoltaic (PV) devices, such as solar cells, modules and systems. It is determined by measuring the electric current and voltage in a circuit, while varying the resistance under precisely defined conditions.
There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc. All these parameters are crucial to know before purchasing or installation of solar panels.
Solar panels or photovoltaic (PV) modules have different specifications. There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc.
The power a module generates in real conditions can exceed the nominal power when the intensity of sunlight exceeds 1000 W/m2 (which corresponds roughly to midday in summer in, for example, Germany), or when sun irradiation close to 1000 W/m2 happens at lower temperatures.
Most solar cells available in the market offer an efficiency of 17-19% and the highest efficiency of a commercial solar panel is about 23%. The fill factor (FF) denotes the efficiency of a solar cell. It is denoted by the ratio of maximum power point (MPP) to the product of short circuit current (Isc) and open circuit voltage (Voc).
Nominal power is also called peak power because the test conditions at which it is determined are similar to the maximum irradiation from the sun. Thus this quantity approximates the theoretical maximum production of the panel on a clear sunny day with the panel oriented perpendicular to the sun.
