Solar Module Descriptions:

Solar Power Modules (known as Photovoltaics - PV) can generate electricity for your home or business, either as part of a stand-alone solar power system, or for buildings already connected to the local electricity network.

PV systems use the most abundant energy source on the planet, solar radiation, to generate electricity. They are silent, consume no fuel and generate no pollution. They also contribute to the reduction of greenhouse gas emissions; a 2kW PV system on a house will prevent the emission of about 40 tonnes of CO2 during its projected 30 year lifetime. Furthermore, the use of PV will reduce your electricity bills and exposure to fluctuating and steadily rising electricity prices.

By doing so, it ensures that the batteries receive the ideal amount of charge, maximizing their efficiency and prolonging their lifespan. Solar controllers are typically utilized in off-grid or hybrid solar systems. Conversely, the inverter converts the direct current (DC) electricity generated by the solar panels or stored in the batteries into alternating current (AC) electricity. AC electricity is the type commonly used in household appliances and the power grid. In grid-tied solar systems, inverters are essential as they enable the solar-generated electricity to be fed back into the electrical grid. This reduces or eliminates the need for conventional electricity from the utility company. Additionally, inverters ensure that the AC power is in sync with the grid's frequency and voltage requirements. To summarize, the solar controller regulates battery charging and controls the power flow from solar panels to batteries, while the inverter converts DC electricity into AC electricity for use in homes or exportation to the grid. Both components have critical roles in a solar power system, ensuring optimal performance, efficiency, and compatibility with the electrical grid or off-grid arrangements.
