A solar inverter is a piece 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
parts in an alternative energy system. Because of this, many people
fall into the trap of underestimating the structure's needs for a solar
inverter and purchase one that handles a smaller capacity than necessary
in order to save money. One of the recommendations to avoid making this
mistake and keep the up-front costs of a solar energy system down is
to initially purchase fewer solar cells and add more later rather than
skimping on the inverter.
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's been discovered that they're
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 to get their money's worth. 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 the fossil fuels and oils on which American
society so heavily relies.
Solar inverters that
are tied to the community's electricity grid help regulate the currents
between the building the solar energy system is powering and the power
lines of the grid. Grid-tie 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.
One who is considering designing and installing a solar
energy system for his or her home should hire a professional to assist
in making sure the system is built properly. There are many variables
to take into account, including the size of the home, the electricity
use of the home, 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 smoothly.
