How much does a solar panel inverter cost?

Quick Takeaways: Solar panel inverter costs can range from £500 to £2,500. String inverters are cheaper than microinverters, but the latter offers more advantages and a longer lifespan. Other factors that can impact the solar panel inverter cost include your system size, inverter efficiency, and whether it’s grid-tied or off-grid.

What is a solar inverter?

An inverter is a vital piece of equipment in a solar panel system and without it, your home would essentially be unable to generate usable power from its solar panels. In this post, we delve into solar inverter costs, the different types of inverters, and their pros and cons. What Are Electrical Inverters?

How much does a microinverter cost?

Microinverters can cost from £20 to £100 a unit. It can cost around £2,500 for the average solar panel system comprising 14 panels, including installation costs like wiring. You’ll face greater upfront costs when creating a system that uses microinverters, and the bill can be quite high if you’re planning on a large installation.

How much does a string inverter cost?

A string inverter can cost around £500 to £1,500 for an average home. They’re a low-cost option compared to other types of inverters. However, a string inverter usually has a lifespan of around ten years, meaning you’ll need to replace it at least once since solar panels can last for 25 years or more.

Which solar inverter is best?

String inverters are the most common in solar energy systems as they are the most cost effective and, while they aren’t as efficient as some other kinds of inverter, they are very reliable, can handle 5 – 10 panels at once and are cheaper to replace.

How much does an SMA inverter cost?

The potential cost of an SMA inverter will ultimately depend on the most suitable model for your solar PV system with more powerful models having higher price tags. They're all still relatively budget-friendly compared to other models, with potential prices ranging from £560 to £2,000+. Get Free Solar Panel Quotes: Get quotes and compare prices.
