SOLUTION EXAMPLES

HYBRID SYSTEM

  • If there is sufficient energy production from the sun, this energy is used directly to run the appliances in the house and also to recharge the battery
  • When the sun is not shining, the energy stored in the battery is combined with energy from the grid to run the house appliances
  • If the battery is discharged, the mains supply is used to fulfill the house needs
  • The system also allows full island operation – without grid power

SYSTEM WITH BACK-UP APPLIANCES 

In the event of a mains failure, the battery will power selected appliances such as the house lights, fridge or freezer. Other appliances will not be powered during a mains failure. The power supply time for these appliances depends on the capacity of the battery.

OFF-GRID SYSTEM

A functional and reliable power grid is not always available. This is even more dificult when there is no grid at all. The only solution to this situation is to install a functional and independent power supply system. In this case, a photovoltaic power system must be designed based on the combined consumption of all electrical appliances in the house.In our conditions (Czech Republic) it is advisable to supplement the island PV system with a supplementary source, e.g. a diesel generator. This source will ensure the supply of energy during periods of insufficient solar energy production.
