Solar off-grid power system
Solar cell module
Solar charge and discharge controller
Off-grid inverter
Generally, the system consists of a photovoltaic square array composed of solar cell modules. The photovoltaic square array converts solar energy into electric energy under the condition of illumination, and supplies power to the load through the solar charge-discharge controller, while charging the battery pack.In the absence of light, through the solar charge and discharge controller by the battery group to dc load power supply, at the same time the battery also directly to the independent inverter power supply, through the independent inverter invert into alternating current, to ac load power supply.
Compared with the common thermal power generation system, the advantages of solar photovoltaic power generation are mainly reflected in the following aspects:
1. No risk of exhaustion;
2. Safe and reliable, noise-free, pollution-free and clean (pollution-free);
3, not limited by the resource distribution region, can use the advantages of building roof;
4. No need to consume fuel and set up transmission lines to generate electricity locally;
5. High energy quality;
6. The construction cycle is short and the energy acquisition time

Solar on-grid system
Solar Panels convert the sunlight to direct current (DC) electricity.
Energy is delivered to your home such as lights and appliances.
The electricity flows through the meter Save more money with net metering
1. Save more money with net metering
Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries
2. Costs
Clearly, less equipment generally means lower installation and maintenance costs. This happens to be the case with most grid-tied systems. Since the power grid functions as a battery for your system, you not only don't have to pay for batteries, you do not have to pay for the maintenance that is involved with those batteries.
3. Reliability
Unlike off-grid systems which may run out of power, grid-tied solar systems are less likely to leave you in the dark at inopportune times. If the power generated from your solar panel system is less than optimal, extra energy will be pulled from the grid. The grid essentially acts as a backup for your system.
