There are many reasons to use solar panels to power your home or business. Solar equipment prices have plummeted in the last decade. Solar power is a wise investment that can save you thousands.
Sunflower Energy Now can offers 3 types of solar power system, including on grid system, off grid system or hybrid system with all necessary spare parts ( solar panels, solar recharge controllers, inverters, batteries etc).

Here we mainly talk about grid tied systems. Our solar systems generate electricity to power your office, farm, restaurant, supermarket or hotel. If more power is needed, such as during the night, electricity is drawn from the utility grid. When your solar panel system produces more energy than is being consumed, the excess is fed to the utility grid and your business is credited with net metering.
On grid solar power system, a system that is connected to the public grid and, therefore, uses electricity from both the solar panel system and the public grid. Because of this, a grid-tied solar system doesn't have to meet all of the electricity demands of the home.
If needed, the home can draw energy from the grid at times (such as on cloudy days or at night) when solar panels are not producing at full efficiency. Likewise, if more energy than is needed is generated by the panels of one home, that excess energy will be fed into the grid for use elsewhere.
From this drawing, you can obviously find how this system works:
1. The sun shines on the solar panels generating DC electricity.
2. The DC electricity is fed into a solar inverter that converts it to AC electricity.
3. The AC electricity is used to power appliances in your home.
4. Excess electricity is fed back into the public grid.
And you can clearly see two meters are necessary for this grid tied system. Net metering is a billing process that credits the owners of grid-tied systems when they produce more energy than the home needs. Because grid-tied homes are usually net-metered, the power meter tracks this exchange between your solar system and the grid.
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.
Moreover, 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.
Compared to other types of solar power system, on grid system is the most cost efficient solution if you have public grid but want to save more electricity costs in daily life.
