Solar Power Conditioning Unit
There are two types of Solar Power Conditioning Units
Off Grid Solar Power Conditioning Unit
A Off Grid system may provide energy to a single consumer, or to an isolated device like a lamp or a weather instrument. Large grid-connected PV systems can provide the energy needed by many customers.
Grid-tie Solar Power Conditioning Unit
Maximum power point tracking
Priority used in Solar Power Conditioning Units
When the solar power and mains power are available, battery will be charged by solar panel. If the battery voltage is too low, then it will also charge the battery through mains power.
When the mains power and solar power are available, the load will be powered by Solar power. If the load requirement is more than the available solar power then the battery will supply the additional load.
When solar power is not available, the grid power will charge the battery & supply the load like any conventional UPS
Photo Voltaic (PV) Modules
Mono crystalline Silicon
Amorphous (Thin-Film) Silicon
This type of solar cell uses layers of semiconductor that are only a few micrometers thick (about 1/100th the thickness of a human hair). While this lowers the material cost, it makes it less efficient than the other types of silicon. However, because it is so thin, this type of cell has the advantage that it can be placed on a wide variety of flexible materials in order to make things like solar shingles or roof tiles
The manufacturing process for amorphous silicon photovoltaic modules is a third-generation technology based upon a highly successful and field-proven large batch approach to amorphous silicon deposition.
Incidentally, the term thin-film is based on the method used to deposit the film, not from the thinness of the film. Thin-film cells are deposited in very thin, consecutive layers of atoms, molecules or ions. Thin-film cells are also usually amenable to large-area fabrication and are suitable for automated, continuous production, arraying and packaging. They can also be deposited on flexible substrates.
Batteries are the storage devises for power. The utility power is in AC form and batteries store it in DC form. The charger section of UPS facilitates this. There are generally three types of batteries, namely, Automotive, Tubular and SMF (Sealed Maintenance Free). Automotive batteries are used for vehicles where discharge is deep for a short duration. Tubular batteries are designed for deep discharge for long durations such as in the case of solar applications. Both Tubular and SMF are used for all industrial uses including UPS.
