Are you planning to switch to clean energy for your home? Going solar is now easier and cheaper than ever before. If you have a small home or a low electricity bill, a 1kW setup can be a useful option. Understanding the 1kW solar panel price with subsidy helps you plan your budget. Government schemes can make rooftop solar more affordable for eligible households.
What Is a 1kW Solar Panel System?
A 1kW (1,000-watt) solar system is a compact renewable-energy setup that generates electricity from sunlight. It typically includes:
- Solar panels
- A grid-tied or hybrid inverter
- Mounting structures
- DC and AC cables
- Safety equipment, such as surge protection devices and earthing kits
The system can supply electricity to your home through the grid-connected setup or, where configured, store energy in batteries.
How Many Solar Panels Are Needed for 1kW?
The number of panels depends on the wattage of each panel. With panels rated around 400W–500W, a 1kW setup generally needs about two or three panels. For example, two 500W panels provide 1,000W of rated capacity. Modern Mono PERC and TOPCon panels can offer higher output in a relatively compact rooftop area.
