New features 2020 Series - Photovoltaic engineering
Electro Graphics releases the latest 2020 Series of electrical and photovoltaic design software. Here are the most important features and enhancements introduced about photovoltaic engineering in the software Solergo.

Personalized incentive related to energy
It is now possible to set incentives that can be applied separately on the energy produced, self-consumed and fed into the grid; they can be combined together.
Single plant layout
If the photovoltaic system is composed of several types of modules and / or more types of inverters, then split into several partial homogeneous generators, Solergo prepares a layout for each generator but now also allows the creation of a single system layout.
When the Single system layout mode is actived, Solergo creates an overall layout of the elements of all the generators designed in a single plan. The final result of the positioning of all the elements of the plant and their automatic connection is the development of the layout of the entire photovoltaic system. It is therefore possible to evaluate the project in its entirety, including the simulation of losses due to shadowing near the modules.
Flexibility in systems with optimizers
Selecting the components of a photovoltaic system it is possible to use power optimizers. Solergo allows to check different connection configurations to power optimizers:
- one photovoltaic module optimizer;
- one optimizer every two modules in series;
- one optimizer for every two modules in parallel (versions with double input for parallel connection of two modules).
The use of power optimizers allows the parallelization of strings formed by a non-homogeneous number of optimizers / modules. For this reason Solergo, in the presence of optimizers, highlights the different strings allowing flexibility in the composition of the connections of each inverter.
Under these conditions, it is also possible to vary the number of connected strings and the number of optimizers in series.
Sizing factors for each inverter
Some grid-connected inverters provide the minimum and maximum sizing factors within which they can be sized in the relevant technical information. It is not uncommon to find inverters that can be oversized at 150%, external value of the default range. The inverter technical data sheet now allows the introduction of these two factors used by Solergo in carrying out the appropriate electrical checks.
Extension and updating of the module and inverter databases
For all the types of devices that can be used in a photovoltaic system, new series have been integrated into the Solergo database.
Service load in plant where whole energy is sold
In photovoltaic plant where whole energy is sold (only one energy meter) now it is however possible to define the service loads (night lighting, alarm, cabin conditioning ...); they are installed specifically for plant services and participate in operating costs. The energy withdrawn from the grid for the service loads is reported in the economic analysis as annual costs. Self-consumed energy is not considered as savings due to self-consumption but helps to reduce grid energy withdrawn.
