- Inverter – a converter that converts the electricity (Direct Current) into Alternating Current (AC) to power the property.
- Battery – stores excess electricity for use when the solar panels are not generating sufficient electricity due to lack of sunlight.
- Charge controller – regulates voltage and current from solar panels to avoid battery overcharging.
- Cables – wiring that connects components.
- Mount – racks and hardware that secure solar panels in preferred position and angle.
- Electrical panel – a breaker box that distributes solar power throughout the property.
- Grid connector – to channel excess electricity to the national power grid or to draw electricity from it when solar energy is low.
Importance of regular maintenance for the longevity of solar panels
The longevity of solar panels does not solely mean the number of years the panels can last. It also means the duration that they can generate solar energy at the most efficient rate.
Regular cleaning is the most basic care owners can do to keep solar panels in good working condition. Additionally, periodic inspection helps to identify and address issues at the first instance. Repair solar panels, when necessary, to extend their lifespan.
Follow the recommended solar panel maintenance schedule by the manufacturer. Adhering to it can protect your warranty coverage. Besides avoiding potential disputes, a maintenance program safeguards your solar investment to generate sustainable energy production effectively.
