Comparison of investment income:

After installing the iPandee MPPT controller solar mate APP on the phone, the owner can see the operation of the entire solar system directly on the phone;


There are two main reasons for customers to install the solar off-grid power generation system:

1. Because the local power supply is unstable, there is often a power outage, which is a headache for a hotel, and also brings a very bad experience to customers who come to the hotel for accommodation;

It directly causes a lot of economic losses to the hotel, so it must at least ensure the normal operation of the hotel's most basic equipment when the power is cut off;

2. The solar power generation system is used to provide electricity for the hotel's electrical equipment, reduce the hotel's electricity expense support, and provide revenue for the installation of customers. The total investment of this system is about 70000 yuan, and the average revenue is 70 yuan/day. The total investment can be recovered within three years.
