Considerations for Isolated Photovoltaic Systems

There are many reasons to choose an insulated system to feed a house or a remote hut. Some people want to avoid the high cost of extending a service line, while others like the independence of home energy production, in addition to having a silent emission-free power source with 25 year warranty.

Isolated systems are very different than interconnected systems. Without CFE as a supplementary electricity source, the size of the photovoltaic system is critical. Isolated systems require the sacrifice of their owners, this means living within the energy budget of the original design, planning for future growth, and having a backup power source for high energy use times or low light output solar. All maintenance and maintenance equipment is also performed at the owner's place, and by the owner or installer, rather than by an electric company.

Should it be disconnected from the mains?

For most homes in the United States, power cuts are infrequent and brief, and an interconnected grid system is the most effective and economical option. The interconnected grid system serves essentially as a giant battery bank, accepting the production of excess photovoltaic energy during the day and providing electricity at night or during cloudy days. In areas of served networks where power outages are common or long, having backup power on the site can make sense. However, it is important to carefully consider the maintenance, cost and potential risks of a battery bank. Selecting just what loads are critical to maintain during power outages will keep the number of batteries needed and the price of batteries low. Isolated network design is most appropriate when there is no network access and is not typically considered for homes that are already connected to the network. Normally, remote properties can be energized by isolated grid systems that use photovoltaic energy at a cost less than the extension of the service line, making it the most economical option.
