Different Types of Domestic Solar Systems

157Views

Residential solar electrical power systems can be divided into three categories: grid-tied, grid-tied with battery backup, and off-grid. The degree to which these three major categories are interconnected with the grid, a typical electricity utility infrastructure, varies. Each type has advantages that influence how well-suited it is to your requirements.

Grid-Connected Home Solar Power Systems

An electricity company grid and the home are both connected directly via a grid-tied solar power system. Grid-tied systems enable households to draw electricity from the utility grid or their own electrical system. The transition between the grid and the domestic system is easy.

This kind of system’s main benefit is its capacity to balance system output and domestic power needs. Net metering is a method of selling excess energy back to the utility when a grid-tied system is generating more energy than the home is using. The house can use electricity from the utility grid if the system is not generating enough power.

Because they require fewer components, grid-tied systems are the most affordable kind of domestic solar electric system.

Grid-connected home solar power system including battery reserve

A grid-tied solar power system provides backup batteries to the system as well as being connected to the conventional utility power grid. The system can balance demand and production and provide protection from power interruptions with the installation of a battery backup.

Production from solar power systems is dependent on the amount of sunlight. When there is plenty of sunlight, production can outpace consumption. Batteries that store the electricity can be charged when production outpaces consumption. Batteries may make up the difference when the systems is generating less electricity than just the household is using.

The electric power grid is also linked to grid-tied systems. Because of this, the homeowners can use the grid during times of high demand and give power back to it during times of high output.

Grid interconnected solutions provide additional flexibility, but not without drawbacks. The effectiveness of the system is decreased as batteries are charged and discharged, and because these systems are more difficult to design and install, they are also more expensive.

Solar Power Systems Off Grid

A domestic off-grid system is totally cut off from the established electric power grid. Batteries are necessary to balance times of surplus demand and production when there is no power grid connection.An electric generator is typically added to the system to prevent power shortages when the solar system is underperforming and the batteries are running low.

Whenever there is an extended period of excess output or an unexpected demand, the generator is often used as a power source. You can also find out more about Residential Solar Power Systems online.

Other Systems

There are minute design differences within each sort of system that have an impact on effectiveness and ease. Review your needs with a solar installation specialist to decide which system is ideal for you. A qualified installer can help you through the complex options for certain systems that best meet your needs.
