Solar Panels: Solar panels are devices that convert sunlight into electricity. They are made up of photovoltaic (PV) cells that generate direct current (DC) when exposed to sunlight. The efficiency and power output of solar panels vary based on their size, material, and technology. For instance, monocrystalline panels typically offer higher efficiency compared to polycrystalline panels. According to the National Renewable Energy Laboratory (NREL), solar panel efficiency can range from 15% to 22% for common commercial models (NREL, 2021).
-
Charge Controller: A charge controller regulates the voltage and current coming from the solar panels to the batteries. It prevents overcharging by diverting excess energy or stopping the current flow when the battery reaches its maximum charge. This component is crucial for maintaining battery lifespan and performance. Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM) are two common types of charge controllers, each providing different levels of efficiency and complexity.
-
Battery Storage: Battery storage is where the electrical energy is held for later use. Common types of batteries used in solar applications include lead-acid, lithium-ion, and gel batteries. Each type has unique characteristics regarding cost, lifespan, energy density, and depth of discharge. For example, lithium-ion batteries have a higher energy density and longer lifespan compared to lead-acid batteries, making them a popular choice for solar setups.
-
Inverter (Optional): An inverter converts the DC electricity stored in batteries into alternating current (AC) electricity, which is used by most household appliances.
