A guide to comparing solar systems before buying: making informed decisions
As solar energy continues to gain popularity, more homeowners, businesses, and individuals are considering the switch to renewable energy. However, choosing the right solar system can be a daunting task due to the variety of options available. This guide aims to provide practical guidance on how to compare solar systems effectively before making a purchase decision, empowering you with the knowledge needed to evaluate and select the right solar system for your specific needs and goals.
Understanding your energy needs
The first step in comparing solar systems is understanding your energy needs. Assessing your energy consumption patterns, electricity usage goals, and budget constraints will help determine the size and type of solar system that best fits your requirements. Analyze your electricity bills to understand your average monthly consumption and peak usage periods. Consider any future changes in energy use, such as plans to add electric vehicles or expand your home or business. This thorough assessment will give you a clear picture of your energy needs and help you select a system that can meet those demands efficiently.
Comparing system technologies
When comparing solar systems, it is essential to understand the different types of solar energy systems available. The three main types are string systems, microinverter systems, and DC optimised systems.
String systems are the most common type of solar energy system. They connect a series of solar panels to a single inverter, which converts the DC electricity generated by the panels into AC electricity for use in your home or business. While string systems are cost-effective and relatively simple to install, they can be less efficient, as the performance of the entire system can be compromised if one panel is underperforming.
Microinverter systems use individual inverters for each solar panel. This setup allows each panel to operate independently, optimising the system's overall performance, especially in shaded or partially shaded environments. Microinverter systems are generally more expensive than string systems but offer higher efficiency and greater flexibility in panel placement. However, they can also experience clipping during peak sunlight conditions, limiting the maximum output of each panel and potentially reducing overall energy production.
DC optimised systems combine the benefits of both string and microinverter systems. They use power optimisers connected to each panel, which maximise the energy output of each panel before sending the DC electricity to a central inverter. This configuration provides improved performance, visibility and safety. SolarEdge is a leader in DC optimised systems, offering advanced technology that ensures maximum energy production.

Storage and compatibility
In addition to these system types, consider battery storage options. Battery storage can significantly enhance the functionality and reliability of your solar system by storing excess energy generated during the day for use at night or during power outages. When comparing battery storage solutions, consider their features, benefits, and suitability for your specific needs. Look for batteries with adequate capacity, a long lifespan, and a strong warranty (at least ten years). Ensure that the inverter you choose is compatible with the battery to guarantee seamless integration and usability, or eliminate compatibility concerns with our end-to-end home solar solutions.
Additionally, consider whether a DC-coupled or AC-coupled battery is more suitable; DC-coupled batteries are generally more efficient as they reduce the number of energy conversions, leading to less energy loss and better overall system performance.

Installation experience and reputation
Choosing the right solar technology is only part of the equation; selecting the right installer is equally important. The experience, reputation, and credentials of solar system installers or contractors play a significant role in ensuring a quality installation. Research the experience and reputation of potential installers by reading customer reviews, checking certifications and licenses, and reviewing past project portfolios. Experienced installers are more likely to provide reliable service and optimal system performance. Click here to find a trusted SolarEdge installer in your area.
Monitoring and maintenance features
Monitoring and maintenance features are essential for ensuring the long-term reliability and performance of your solar system. Different solar system providers offer various monitoring and maintenance options, including real-time performance monitoring, remote troubleshooting capabilities, and service support options. For example, the mySolarEdge app allows users to monitor their solar system's performance in real-time, providing valuable insights into energy production and system health. Ensuring that you can monitor your investment's performance helps maintain optimal efficiency and quickly address any issues that arise.
