System Capacity
Understanding how much power your solar system can generate
Learn about solar system components in simple terms with visual guides. Perfect for beginners who want to understand solar technology.
Understanding how much power your solar system can generate
System capacity refers to the maximum amount of electrical power your solar system can produce under ideal conditions. It's measured in kilowatts (kW) or kilowatt-hours (kWh).
Think of it like the engine size of a car. A larger engine can produce more power, just like a larger solar system can generate more electricity.
Pro Tip: Your system capacity should match your electricity consumption. Check your monthly electricity bill to determine your needs.
The higher the bar, the more power the system can generate
On-grid vs Off-grid solar systems
On-Grid: If you have reliable grid power and want to save money on electricity bills.
Off-Grid: If you're in a remote area without grid access or want complete energy independence.
Types and efficiency of solar panels
Solar panels are devices that convert sunlight into electricity. They're made up of many solar cells connected together.
Efficiency Explained: Efficiency tells you how much of the sunlight hitting the panel gets converted to electricity. Higher efficiency means more power from the same size panel.
Converting DC to AC power
An inverter is a crucial component that converts the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity that your home can use.
Solar panels produce DC power, but your home appliances use AC power. The inverter is like a translator that converts the language of electricity so your devices can understand it.
How solar panels are installed
Mounting structures securely attach solar panels to your roof or ground, ensuring they're positioned optimally to capture sunlight.
Important: Proper mounting ensures your panels can withstand wind, rain, and other weather conditions for 25+ years.
Energy storage solutions
Batteries store excess electricity generated by your solar panels for use when the sun isn't shining or during power outages.
Solar panels only produce electricity during daylight hours. Batteries allow you to store excess energy for use at night or during cloudy days.
Capacity Matters: Battery capacity is measured in kilowatt-hours (kWh). A 10kWh battery can power a typical home for 8-10 hours.
Single vs Three-phase power
Power phases refer to how electricity is distributed to your home. Most residential homes use single-phase power, while larger buildings use three-phase power.
Think of phases like lanes on a highway. Single-phase is like a one-lane road, while three-phase is like a three-lane highway that can carry more traffic (power).
How to Know Your Phase: Check your electricity meter or consult with your electrician. Most homes in India use single-phase power.
One power line
Standard homes
Three power lines
Large buildings
Now that you understand the components, it's time to create your custom solar kit!
