What is the main purpose of a solar inverter?
A solar inverter is responsible for converting the DC (direct current) electricity generated by solar panels into AC (alternating current) electricity, which can be used to power household appliances.
What type of solar panel is most commonly used in residential installations?
The most commonly used type of solar panel in residential installations is the monocrystalline panel, known for its high efficiency and long lifespan.
How does shading affect solar panel performance?
Shading on solar panels reduces their efficiency by blocking sunlight from reaching the cells, leading to a significant loss in energy production.
What is the primary advantage of a grid-tied solar system?
A grid-tied solar system allows excess energy generated by the solar panels to be sent back to the grid, which can help offset electricity costs through net metering.
What is the typical lifespan of a solar panel?
The typical lifespan of a solar panel is about 25 to 30 years, with most panels still operating at about 80% of their original efficiency after this period.
What is the function of a charge controller in a solar energy system?
A charge controller regulates the voltage and current coming from the solar panels to prevent overcharging the battery bank, ensuring optimal battery health and longevity.

How can solar panels be mounted on a roof?
Solar panels can be mounted on a roof using roof-mounted racks, which allow the panels to be securely attached and tilted to the optimal angle for sunlight exposure.
What is net metering in a solar power system?
Net metering allows solar system owners to receive credits for excess electricity that is sent back to the grid, which can offset electricity costs during periods of low solar generation.
What is the most efficient orientation for solar panels?
The most efficient orientation for solar panels in the Northern Hemisphere is south-facing, as this allows the panels to receive the maximum amount of sunlight throughout the day.
