1. What is off grid system? 离网系统介绍

An off-grid solar system is a solar panel system that generates electricity, stores that power in solar batteries, and runs independently from the power grid. These systems encourage off-the-grid living, a lifestyle centered around energy independence and self-sustainability.

Off-grid solar systems must be designed appropriately to generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in the depths of winter when there is generally much less sunlight.

The cost of an off-grid solar system has an even wider range because there are a variety of sizes, applications, and components that impact the price. The high cost of batteries and off-grid inverters means off-grid systems are much more expensive than on-grid systems, and so are usually only needed in more remote areas that are far from the electricity grid. However, battery costs are dropping, so there is a growing market for off-grid solar battery systems, even in cities and towns.

An alternative to off-grid solar systems is a hybrid system, which remains tied to the grid but includes a solar battery bank to store excess energy

2. Advantages of an off-grid solar system 离网系统优势

(1) Freedom from electrical bills. With an off-grid system, you will not receive an energy bill from your utility.

(2) Energy independence. You will produce 100% of the electricity you use.

Protection from power outages. Your off-grid system will work even if the power grid experiences an outage.

(3) Provides reliable electricity in remote or rural locations. The power grid does not connect to some remote or rural locations. An off-grid system provides electricity in these cases.
