Since the groundbreaking discovery in 1954 by Bell Telephone scientists that silicon, an abundant element found in sand, could generate electricity when exposed to sunlight, solar technology has made remarkable strides. Today, more than 2 million homes in Ireland have embraced solar panel systems as a clean and cost-effective energy solution.
Solar panels have revolutionized our ability to tap into the virtually limitless power of the sun. The functionality of solar panel systems is straightforward:
1. Sunlight absorption: Solar cells within the panels absorb the sun's energy during daylight hours.
2. Energy conversion: Solar cells convert the absorbed sunlight into direct current (DC) energy.
3. Inverter conversion: The DC electricity is then sent through an inverter, transforming it into usable alternating current (AC) electricity, the same type that powers your home appliances.
4. Energy utilization: You can utilize the AC electricity generated by your solar panel system within your home, store it using a solar battery, or even feed it back into the grid.
In the following sections, we will briefly overview solar panel systems and the essential equipment required to harness solar power. Already well-versed in solar equipment functionality? Fantastic!

Solar panels are devices designed to capture sunlight and convert it into usable electricity. Typically composed of solar cells primarily made from silicon, solar panels also consist of wiring, a sturdy metal frame, and a protective glass cover. A standard solar panel measures around four feet in width and six feet in height.

Simplicity is the name of the game when it comes to solar panel systems. Solar panel installations are highly efficient and easy to maintain, with only four main components and no moving parts. Let's explore the essential components of a solar panel system:
1. Solar Photovoltaic Panels: These panels convert solar energy into electricity. Composed of silicon solar cells, they are enclosed in a glass sheet and held together by a sturdy metal frame. The cells capture sunlight and activate electrons, generating a flow of electrical current. The output from multiple cells is combined within the panel to generate electricity. Solar panels typically measure around 4 feet by 6 feet and weigh approximately 30 pounds. Recent advancements include "half-cut" solar panels, where cells are halved to increase efficiency.
2. Inverters: Inverters play a crucial role in converting the direct current (DC) electricity produced by solar panels into the alternating current (AC) electricity used to power household appliances. These devices ensure that the electricity the panels generates is compatible with your home's electrical system.
3. Racking and Mounting Systems: These systems provide the necessary support and securement for your solar panels. Racking systems are used to affix the panels to your roof while mounting systems are employed for ground-mounted installations. These components ensure the panels are properly positioned to receive optimal sunlight.
4. Performance Monitoring Systems: Performance monitoring systems are employed to track and monitor the output and health of your solar panels and inverters. These systems provide valuable information about the energy production of your solar panel system, allowing you to assess its efficiency and performance over time.
It's important to note that not all solar panels are created equal. When selecting solar panels for your home, consider product quality, durability, and long-term performance. Refer to the EnergySage Buyer's Guide for Solar for a comprehensive guide on evaluating solar panels.

Solar panels generate direct current (DC) electricity from the sun's energy. However, most homes and businesses use alternating current (AC) electricity. This is where inverters come into play. They convert the DC electricity produced by the panels into usable AC electricity. In Ireland, you have two main solar inverters to choose from: string (or centralized) inverters and microinverters, with an additional option of power optimizers.
String (or centralized) inverters: This type of inverter connects your entire array of solar panels to your electrical panel. It is a cost-effective and durable option that has been widely adopted. Multiple strings of panels can be connected to a single inverter. However, if one panel in a string is shaded or experiences reduced performance, it can impact the overall output of that string.
Microinverters: With microinverters, each solar panel is equipped with an individual inverter. This setup allows each panel to maximize its production potential. Microinverters are particularly useful if your panels are shaded at different times of the day or are installed facing various directions. While microinverters offer enhanced performance, they tend to be more expensive than string inverters.
Power optimizers: Power optimizers provide a hybrid solution that combines aspects of both microinverters and string inverters. These optimizers are installed at each panel, conditioning the DC electricity before it reaches a centralized inverter. Power optimizer systems perform well even when panels are shaded or installed facing different directions. They offer a middle-ground option in terms of cost, falling between string inverters and microinverters.
Racking and mounting systems are essential for securely installing solar panels on your roof or the ground. To achieve the best performance, solar panels should ideally face south and be installed at an angle between 30 and 45 degrees (adjusted based on your proximity to the equator). While panels facing east or west at a pitch angle of five degrees or more can still function well, they may produce slightly less electricity than in optimal conditions. Most residential solar systems use "lie-flat" roof-mounted setups where the panel pitch matches the roof's pitch. However, in some cases, racking systems can be employed to tilt or adjust panel angles for better sun exposure.
1. Fixed mounts: These mounts keep the panels stationary, providing a stable installation.
2. Tracking mounts: These mounts allow panels to follow the sun's movement throughout the day (single-axis) or during changing seasons (dual-axis). However, tracking mounts are typically suitable for ground-mounted solar systems.
Performance monitoring systems provide valuable insights into the operation of your solar panel system. By measuring and tracking electricity production hourly, you can accurately assess its performance and financial benefits. Most residential inverters come with production monitoring apps that allow you to monitor panel output. Some apps may also include consumption monitoring features at an additional cost, helping you track overall savings.
1. On-site monitoring: The monitoring device is physically located on your property and records electricity production data.
2. Remote monitoring: Your solar PV system transmits performance data to a monitoring service you can access online or mobile.
