FAQs 6

Should I install an inverter on my solar panel array?

Installing an inverter whose maximum capacity is greater than the nominal capacity of your solar panel array may be an option if you’re looking to expand your solar panel array at some point in the future, but it is not generally recommended.

How does a solar inverter affect efficiency?

The efficiency of the inverter drives the efficiency of a solar panel system. Inverters change the Direct Current (DC) from solar panels into Alternating Current (AC), which is what we use in our homes and businesses. This article talks about how to pick the right size solar inverter.

How do I choose a solar inverter size?

To calculate the ideal inverter size for your solar PV system, you should consider the total wattage of your solar panels and the specific conditions of your installation site. The general rule is to ensure the inverter’s maximum capacity closely matches or slightly exceeds the solar panel array’s peak power output.

Should a solar inverter be oversized?

However, slight over-sizing of the solar panels compared to the inverter capacity (up to 133% under certain guidelines) can sometimes yield better overall efficiency due to the variable nature of solar irradiation throughout the day. The ratio for inverter sizing often depends on specific system requirements and local regulations.

Can a solar array put out more power than an inverter?

According to the Clean Energy Council, you can have a solar array that can put out up to 30% more power than the inverter is rated for and remain within safe guidelines.

What are the disadvantages of a solar inverter?

4. Efficiency Gains and Losses Oversizing the solar panel array relative to the inverter’s capacity (up to 133% is common) can increase energy production during periods of low solar irradiance but may cause clipping at peak production times.
