A solar inverter is a crucial component in a solar energy system. It performs the essential function of converting the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity. This conversion is important because most home appliances and the electric grid operate on AC electricity, not DC.

Here’s a breakdown of its key functions:

1. DC to AC Conversion: Solar panels produce electricity in DC, but homes and businesses use AC power. The solar inverter changes the DC power from the panels into usable AC power.
2. Maximizing Energy Production: Many solar inverters are equipped with Maximum Power Point Tracking (MPPT) technology. This ensures that the solar panels operate at their most efficient point under various conditions, like changing sunlight and temperature, maximizing the energy production.
3. Grid Interaction: For systems connected to the electrical grid (grid-tied systems), the inverter can synchronize the AC power it produces with the grid’s power. This includes matching the voltage, frequency, and phase of the grid electricity.
4. Monitoring and Management: Modern solar inverters also provide monitoring features, allowing homeowners and businesses to track the performance of their solar panels, including energy production and system health.
5. Safety and Compliance: Inverters ensure that the solar system complies with safety standards. For example, they can automatically shut down the solar system in case of a power outage (a feature known as anti-islanding) for the safety of utility workers who might be repairing the grid.

There are various types of solar inverters, including string inverters, microinverters, and power optimizers, each with its own specific advantages and applications depending on the solar energy system’s size and requirements.

In your home, the solar inverter is typically installed in a loft or garage space. The direct current (DC) cables, emanating from your solar panels, lead into a specialized DC isolator switch. This is a crucial step in the setup, as it ensures safety and effective power management. The cables are then connected to the inverter. It’s important that the inverter is appropriately matched to your solar panel array’s size, measured in kilowatts peak (KWp). This ensures optimal efficiency and compatibility with the specific solar modules installed on your roof.

The inverter’s placement is also key. It needs to be situated in a spot that is not obstructed, allowing for unimpeded airflow around it. This is important for maintaining its operational integrity and cooling efficiency. Additionally, the inverter should be mounted on a fire-retardant board. This board must be securely attached to stable structural elements of the building, like roof members or the gable end, to ensure safety and stability.

From the inverter, an alternating current (AC) cable is routed downwards to another isolation switch, this time for AC. This setup includes a solar generation meter, which monitors and records the electricity produced by the solar panels. The AC cable is then connected to a 16-amp mini circuit breaker within the property’s consumer unit. This breaker is a crucial component that protects your electrical system from overloads or short circuits.

Once this entire system is connected to the national grid, your solar installation is ready to start generating electricity. At this point, you’ll begin producing your own electrical power, contributing to your home’s energy needs and potentially reducing your reliance on external power sources.

The process of installing solar panels in a domestic setting is generally efficient and minimally disruptive, often completed within a single day. The preparation for the installation typically begins a few days earlier, with the setup of scaffolding to ensure safe access to the roof. On the day of installation, a specialized team arrives to meticulously mount the solar panels onto the roof. They use precision and care to ensure the panels are correctly aligned and securely attached. Following this, the team installs an inverter, an essential component that converts the solar energy into usable electricity for the home. The final stage of the installation involves careful internal wiring, connecting the solar panel system to the home’s electrical network. This process is done with attention to safety and efficiency, ensuring a smooth integration of the solar energy system into the home’s existing electrical infrastructure.

When installing solar photovoltaic (PV) panels, we adopt rigorous measures to ensure their secure attachment to the building’s structure. This is achieved using a robust and reliable roof hook and rail system, which anchors the panels firmly to the building. To further enhance stability and reduce the risk of wind damage, we always mount our panels at a minimum distance of 30 centimeters from the roof’s edge. This strategic positioning is crucial in mitigating the effects of excessive wind loading on the panels. Our commitment to safety and durability was exemplified during the hurricane-force winds experienced in February 2014. Throughout this extreme weather event, not a single solar panel installed by Teevo Energy was dislodged or blown off from any roof, underscoring the effectiveness of our installation approach and the resilience of our mounting system.
