How a PV Grid-Tied Inverter Affects the Cost of Solar Power Generation
A Solar PV system can be described as a collection of solar PV cells that are connected together. The basic function of the solar cells is to convert solar energy into DC current. Solar cells produce different output voltage depending upon the type and number of the solar cells present in the panel. The solar cells can be single side silicon semiconductor cells or multi-sided gallop process cells. A photovoltaic system can use a combination of both types of cells.
There are mainly three types of PV inverters available in the market - Stable inverters, Non-stability controlled or NCV inverters, and Grid tie inverters. All these are designed to meet the same criteria. They are designed to serve as an energy regulator, which regulates the amount of energy that flows into the electrical grid of a house or building. To serve as an energy regulator, they are fitted with a control device, which controls the generation of energy in sync with the electricity demand of the household. This ensures maximum power supply to the AC appliances at the end of the day.
If you install a Stable PV Plant then it will remain fixed for the entire time. It will automatically adjust itself based on the changes in the sun-signal. On the other hand, a Non-stability controlled or NCV inverter will change its mode when the load demand changes. In such a situation, the inverter will switch to the thermal mode, which will further consume less power. But if the load demand does not change, then the NCV inverter will automatically default to the thermal mode.
These two types of solar inverters work in a very simple manner. They directly connect the DC solar array to the battery bank. This is done so that the storage batteries can charge up and then store the power for use at night. The storage batteries can be DC or AC powered. The most important feature is that the inverters directly connect to the power source.
How this works: This particular inverter grid tie system requires direct connection between the PV solar array and the utility power source. There must be a direct connection between the battery bank and the utility power source. For this to happen, the power supplied to the inverter must be equal to the power supplied to the utility. This will ensure that the inverter maintains constant voltage all through the day. This will further ensure that it provides power at an optimum level.
A grid tie inverter is often used in conjunction with a utility-grade inverter. In this case, the two inverters are tied in series to a single utility. This is used to power the entire plant, ensuring that the inverter performs at its best throughout the day.
Grid-tie PV inverters are a growing trend throughout the PV industry. This is because the demand for solar electricity is increasing exponentially. This is also because it allows more than one PV system to be tied into the same utility, as all of the PV cells need to be in place and functioning properly in order to collect the power for the utility. With the increasing popularity of PV cells and their photovoltaic capabilities, this solution is becoming more popular with both commercial and residential customers.
The growing need for grid-tied PV cells means that the cost of having a solar power plant built is increasing. This is leading to a tremendous push towards making the plants more reliable. The grid-tie inverters take care of the reliability factor by tying the PV system together into one, reliable component. They help to make sure that the PV system performs as desired while keeping the cost of ownership down. This has allowed more customers to invest in solar power generation without worrying about the high costs associated with the PV systems on their own.
