Solar Inverter

A solar inverter is a part of the solar energy puzzle. Its purpose is to change the direct current (DC) electricity that is generated from a photovoltaic panel into an alternating current (AC) that can be used by in-home appliances and the community electricity grid. Because all photovoltaic panels produce electricity in DC, an inverter is required for all solar power systems to make the electricity usable.

The solar inverter is often one of the most expensive components in an alternative energy system. As a result, many people fall into the trap of underestimating their requirements for an inverter and purchase one that handles a smaller capacity than necessary in order to save money. In order to eliminate this mistake and reduce up-front investment, it is recommended that consumers install fewer solar panels at the outset and then add more lately.

There are many manufacturers that are competing in the solar inverter market. While there have been a lot of American-made inverters in the past, in recent years it has been discovered that they are not always operating at their advertised efficiency, resulting in several companies going out of business. This has opened the market up to several international companies, and many of the most recognized solar inverter brands are European.

One of the biggest issues of a solar power system is efficiency. The cost of building and installing a system is often expensive, and those who are willing to make the financial investment in solar energy want to be sure they receive value for their investment. Not only do the solar cells need to convert the sun’s energy to electricity efficiently, but the solar inverter has a responsibility in efficiency as well. Manufacturers of inverters are working to improve their products’ efficiency in order to make the products more marketable and attractive to those interested in solar power. Any possibility of saving more money in the use of a solar power system will increase the odds of people converting to solar power and easing the demands of fossil fuels and oils on which American society so heavily relies.

Grid-connected systems that feed into and from the grid are usually required to have anti-islanding protection built in. The anti-islanding ensures that if a fault occurs within the grid, the solar powered system will disconnect from it immediately to prevent feeding more electricity into an already hazardous situation. Reconnecting to the grid can sometimes be complicated, but in order to have a completely safe system, it is required to follow the anti-islanding regulations set forth by local power companies. The reconnection should happen automatically.

It is recommended, that, when consumers investigate the option of changing over to renewable energy, they consult a professional to assist them in selecting the optimal solution that will satisfy their requirements. There are many variables to take into account, including the size of the home, electricity consumption, possible future fluctuation in the energy use of the home, as well as the types and sizes of the photovoltaic cells and solar inverters necessary to keep the system running efficiently.
