It is not possible to predict a number since the number of solar panels is determined by the electrical consumption of the property and not on the size of a house or business.
No. The system was sized to cover a certain percentage of your electricity consumption. If energy consumption increases, the savings will not be noticeable. In case this is your objective, we recommend talking to your EcoCentro Photovoltaic Advisor about your plans to achieve the correct dimensioning of your photovoltaic system.
An isolated or autonomous system (with batteries) can be dimensioned to cover a determined consumption of energy, it must be taken into account that the greater the electrical consumption, the greater the number of batteries.
In an interconnected system, the solar panels will inject energy into the entire electrical circuit where the meter is connected, this means that the energy generated by the panels is distributed in all the appliances connected to this circuit as well as the CFE electrical network and not only to air conditioning.
There is no minimum number of solar panels to install, however, in order to observe savings, the system must be adequately dimensioned. There are two types of interconnected photovoltaic systems; those that use a central inverter for energy conversion and distributed conversion systems (with micro inverters). The latter allow the installation of a single solar panel. On the other hand, central inverters have a lower starting voltage limit; 3 to 4 solar panels are generally necessary to cover this requirement (depending on the power of the solar panel).
A survey must be carried out where the true dimensions of the roof are recorded, as well as all the equipment that may represent an obstacle or cause some shading on the solar panels. With this information, the design of the system is carried out and the exact number of Solar Panels that fit in a roof is determined.
No, since the function of the inverter is to connect to the existing electrical network in the home. Likewise, the necessary electrical protections are installed to avoid any disturbance to the network and therefore to your electrical appliances.
