In 1961, mathematician and meteorologist Edward Lorenz found that weather cannot
be predicted with zero uncertainty. This is why meteoroligists today rely on statistics and probability to perform forecasts.

Being dependent on weather, solar and wind energy production cannot be predicted but can be estimated using measurements of daily, monthly and yearly irradiation and wind speed in a certain location.
What can be noticed from statistical data is that when solar irradiation is low (for example because of bad weather), wind blows at higher speeds and when solar irradiation is high most likely there will be almost no wind.
The same pattern of data can be found with seasonal variation of irradiance and wind speed. In summer, usually, wind speeds are low and the sun shines brightest and longest while in winter the wind is strong when less sunlight is available.

This behavior can be used to reduce the variability of the energy produced by PV systems and wind power systems due to weather conditions.
An energy production system using both solar and wind power as energy sources is called hybrid power system.

A hybrid power system is made of the following components:

• PV modules
• One or more wind turbines
• Battery energy storage system
• Power electronics to convert and regulate the produced energy
• Engine generators can be used to reduce the size of other components (especially batteries).

This kind of power production systems are very complex and requires a good design to work and to be cost-effective.
In order to properly design a hybrid power system, it is necessary to have knowledge of several fields of engineering (electrical engineering, electronics, mechanics, civil engineering and control theory).
Our goal is to provide our customers, who want to install a hybrid power system, with high quality designs based on most recent technical standards and technologies.

Hybrid power systems are centralized power production systems feeding an isolated load (stand-alone power system) or connected to the national distribution grid (hybrid power plant).
If you have distributed energy resources (DER) and multiple loads connected to a local electrical grid then you have a microgrid.
