System losses [%] : The estimated system losses are all the losses in the system, which cause the power actually delivered to the electricity grid to be lower than the power produced by the PV modules. There are several causes for this loss, such as losses in cables, power inverters, dirt (sometimes snow) on the modules and so on. Over the years the modules also tend to lose a bit of their power, so the average yearly output over the lifetime of the system will be a few percent lower than the output in the first years. The default value is 14%, you can keep this value for a first estimation.If you have a good idea that your value will be different (maybe due to a really high-efficiency inverter) you may reduce this value a little. You can also increse it if you think that you have more losses like losses due to near shadings (buidings, tress,...).Mounting position : Select the way your solar panels are mounted. Slope [°] :This is the angle between horizontal and surface of the panel, o° is for horizontal, 90° is for vertical. Azimuth [°] :The azimuth, or orientation, is the angle of the PV modules relative to the direction due South. -90° is East, 0° is South and 90° is West.. Financial analysis : PV electricity price PV system cost (your currency) : Here you should input the total cost of installing the PV system, including PV system components (PV modules, mounting, inverters, cables etc.) and installation costs (planning, installation....). The choice of currency is up to you, the electricity price calculated by PVGIS will then be the price per kWh of electricity in the same currency you used. Interest [%/year] : This is the interest rate you pay on any loans needed to finance the PV system. This assumes a fixed interest rate on the loan which will be paid back in yearly installments for the lifetime of the system. Lifetime [years]* :This is the expected lifetime of the PV system in years. This is used to calculate the effective electricity cost for the system. If the PV system happens to last longer the electricity cost will be correspondingly lower Note that PVgis can include the terrain shadows and it offers 2 options :- Use the calculated horizon from PVGIS (you can even download the remote horizon data of the location. Nearest shadings due to buildings or trees is not included.- Upload horizon file, if yu have your own horizon dataset. RESULTS Then

Output Characteristics of PV Panel Output Considering Different

Power optimizers are electronic devices, which aim to draw the maximum energy possible from the PV modules within an array (i.e. they try to ensure that each module is working at its MPP at any time).There is usually one device per PV module, often directly mounted on the module rear side. As is well known, the current in a string of modules is limited by the current of the weakest module. Optimizers are DC-DC converters, which convert the (Vmpp, Impp) maximum operating point of the PV module into a (Vout, Iout) representing the input power, but with the constraint that the output currents are the same for all optimizers within a string. If we consider the I/V curve at the output of the optimizer, this condition is equivalent to extending the voltage range for which the device can provide the maximum power Pmpp of the considered device, so that one can find a common current for several optimizer power outputs. See the Optimizer's definition dialog, page "Output I/V behavior", for some examples. BenefitsRegarding power enhancement, the optimizers cannot create energy, of course. The benefit we can expect from Optimizers is the recovery of electrical mismatch losses. The mismatch may be of two different kinds: -Current differences: all modules of a real PV array cannot be rigorously identical. There may be differences expressed by a tolerance range, especially in current, within a given string. During the PVsyst simulation, the mismatch between modules is characterized by a constant derate factor. But this loss may significantly increase along the years, as the degradation of the modules is not homogeneous. Current differences may also be the result of uneven soiling of the modules. Another cause of mismatch may be due to different orientations of modules within a string. This situation is not allowed for PVsyst simulations presently. -Partial shadings of some sub-modules: when one or several cells are shaded, the whole sub-module becomes reverse-biased, the by-pass diode is activated above the current corresponding to the residual power of the diffuse part. This results in a quite different situation as the previous one: the true Pmpp maximum is decreased in voltage (voltage of each sub-module, plus the diode reverse voltage), but the current remains the same Impp. When you have one only string per MPPT input, the Vmpp of the string is reduced but the Impp current is identical for all modules, so that the SMP3 Pyranometer The SMP3 is a smart pyranometer with low maintenance and industry standard digital and analogue amplified outputs. Based on the proven CMP3 technology the SMP3 adds Modbus® interface, improved response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological stations easy. The SMP is protected against over voltage, reversed polarity and short circuiting. Because all SMP’s have identical sensitivity and connections exchanging instruments during recalibration is easy.SmartExplorer Windows™ for data logging, display of data and Modbus® address setting is provided as standard.SMP3 measures global solar radiation on a horizontal plane. When tilted with the same angle as a PV panel it measures the tilted global radiation, for PV module efficiency calculations.

Inverter reports total output, not jus PV output

The Lookout PID Auto Tune Example is designed to allow you to connect variables from your "real" process to various items in this example. This allows you to tune your feedback control loops online with this example.The example uses a software simulation of a system by default. This is so that when the example is opened, it demonstrates the PID control loop and autotuning functionality immediately, without any changes to connections. It turns out that this "simulated process" was mathematically defined in such a way that it just so happens the output stabilizes to 20 less than the setpoint. If you change the example to connect to a real system, or change the math in the "temperature_simulated" expression, then this will not be the case.The [PV] expression is a static symbolic link. This allows you to connect the PV (Process Variable) expression to any data member in any running process on any computer on your network. Since by default this example uses a software-simulated system for reasons explained above, this expression connects to "Temperature_simulated" by default.To change the connections within this process from the default, built-in simulation, simply follow the step-by-step procedures in the documentation included with the example. The procedure has you connect the PV expression to your process variable, and the POTVoltage expression to your output or manipulated variable. It also walks you through re-scaling of all the outputs, as the real-world values are likely engineering units and are probably not scaled from 0 to 100.As a final note, this auto-tuning procedure uses a Ziegler-Nichols procedure, which is an industry-standard procedure for tuning feedback control loops. Personally, I think it results in too much derivitive action (the "Rate" constant), which causes your manipulated variable to jitter when small amounts of system noise are present. So I usually reduce
