Battery capacity required by the system is 45.6Ah × 5 = 228Ah. The minimal battery capacity for a safe operation is 228Ah/0.8=285Ah. Sizing of a PV system can be carried out using a worksheet in which the PV system design rules are summarized.
Batteries are a major component in the stand-alone PV systems. The batteries provide load operation at night or in combination with the PV modules during periods of limited sunlight. For a safe operation of the PV system one has to anticipate periods with cloudy weather and plan a reserve energy capacity stored in the batteries.
The number of modules in series is determined by dividing the nominal PV system voltage with the nominal module voltage (in the specification sheet under configuration). The total number of modules is the product of the number of modules required in parallel and the number required in series.
All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery.
The nominal voltage of the PV system is 12V and the nominal module voltage is 12V. The number of modules in series is 12V/12V = 1 module. The total number of modules in the array is 5 × 1 = 5 modules. 6. Determine battery size for recommended reserve time Batteries are a major component in the stand-alone PV systems.
