What Type of Solar System Do I Need for my Home?

Investing in solar energy for your home or business is a smart decision that can save you money while helping the environment. However, choosing the right type of solar system can be a bit overwhelming with various options available. In this blog, we will explain the key differences between three main types of solar systems: standard string systems, optimiser systems, and microinverter systems.

Standard String System

A standard string system is the most common and traditional type of solar installation. In this setup, solar panels are connected in series, forming a “string.” The electricity generated by these panels flows to a central inverter, which converts the direct current (DC) electricity into alternating current (AC) electricity for use in your home or business.

PROS:

**Simplicity:** This system has a straightforward design with fewer components, making it easier to install and maintain.

**Cost-Effective:** Generally, string systems are less expensive upfront compared to other types of solar systems.

**Reliable:** Proven technology with a long track record of performance.

CONS:

**Efficiency Limitations:**

The performance of the entire string is affected by the weakest panel. If one panel is shaded or not functioning optimally, it can reduce the efficiency of the whole system.

**Limited Monitoring:**

Typically offers less detailed monitoring capabilities compared to systems with optimisers or microinverters.

Optimiser System

An optimiser system improves upon the standard string system by adding power optimisers to each solar panel. These optimisers are small devices that adjust the output of each panel to maximise overall efficiency before sending the electricity to a central inverter.

PROS:

**Enhanced Performance:** Power optimisers help mitigate the impact of shading or obstructions by allowing each panel to operate at its maximum potential independently.

**Monitoring:** These systems often come with advanced monitoring capabilities, enabling you to track the performance of each panel individually.

**Better Efficiency:** Improved energy yield compared to standard string systems.

CONS:

**Higher Cost:** Adds some cost to the system compared to standard string systems.

**Complexity:** Slightly more complex installation and maintenance than standard string systems.

Microinverter System

A microinverter system takes individual panel optimisation a step further by attaching a small inverter to each solar panel. Instead of relying on a central inverter, each panel converts its DC electricity to AC electricity independently.

PROS:

**Maximum Efficiency:** Since each panel operates independently, issues with one panel do not affect the performance of others. This setup is particularly beneficial in installations where shading or varied panel orientations are concerned.

**Scalability:** Microinverter systems are highly scalable, making them ideal for small and large installations.

**Detailed Monitoring:** Offers panel-level monitoring for detailed performance tracking.

CONS:

**Cost:** Microinverters are typically a little more expensive than string inverters or optimisers.

**Increased Complexity:** More complex installation and maintenance due to the higher number of inverters.

Which System is Right for You?

The best solar system for you depends on several factors, including your budget, roof layout, shading, and performance expectations. Here’s a quick summary to help you decide:

**Standard String System:** Best for those seeking a cost-effective solution with a simple design and no shading issues.

**Optimiser System:** Ideal for installations where shading is a concern and panel-level monitoring and performance are important.

**Microinverter System:**

Perfect for complex roof layouts, significant shading, or those looking for the highest possible efficiency and flexibility.
