Can a 4KW Solar System be sold back to the grid?

Any excess solar energy generated by the 4kW system that is not used can be sold back to the grid. This means that homeowners can earn money for the extra electricity their solar system produces. With the current electricity costs, it is possible to achieve a 20% return on investment per year based on the panels’ cost.

Why should you install a 4KW Solar System?

By installing a 4kW solar system, you can significantly reduce your monthly electricity expenses and potentially eliminate them altogether. In addition to saving money on electricity bills, homeowners can also generate income through solar energy. Any excess solar energy generated by the 4kW system that is not used can be sold back to the grid.

How many kWh can a 4KW Solar System produce?

(Load Per Day) On average, a 4kW solar system can produce an estimated 20 kWh per day. This output is based on the condition that the panels receive at least 5 hours of direct sunlight. When calculated on a monthly basis, this amounts to approximately 600 kWh, and over the course of a year, the system can produce around 7,300 kWh.

Which batteries are best for a 4KW Solar System?

Due to its higher capacity and efficiency, lithium polymer batteries are highly recommended for a 4kW solar system. Opting for lithium polymer batteries allows homeowners to significantly reduce the number of batteries needed, cutting costs in the process.

How many batteries are needed for a 4KW solar panel system?

The number of batteries needed for a 4kW solar panel system depends on the battery type chosen – lead-acid or lithium polymer. Assuming the recommended lithium polymer batteries, a system with a 4kW capacity would require approximately 25 kWh worth of batteries.
