Is a 4KW solar panel system a good choice?

A 4kW solar panel system is often the right choice for a three-bedroom household, but it depends on your present and future consumption, as well as the solar battery you choose. In this guide, we’ll explain what a 4kW solar panel system is, how much it costs, and how many devices it can power.

What is a 4KW Solar System?

The solar panels are at the core of a 4kW solar system, also known as photovoltaic (PV) panels. These panels are responsible for capturing sunlight and converting it into electricity. In a 4kW setup, multiple panels collectively produce 4,000 watts, or 4 kilowatts, of power under optimal conditions.

How many solar panels are in a 4KW system?

The number of solar panels in a 4kW system depends on the size of the panels themselves. If you have a 400W panel, it will produce 400 watt-hours in standard test conditions, which includes a cell temperature of 25°C and solar irradiance of 1,000W per m², and is how every company checks a solar panel’s capabilities.

Should you install a 4KW Solar System?

Installing a 4kW solar system can be beneficial as it helps to combat power outages and significantly reduce electricity costs. On average, a 4kW solar system can provide up to 3000 watts per day, sufficient to charge a 3-bhk home for 12 hours. These affordable solar power systems require a small rooftop area to accommodate.

How much does a 4KW Solar System cost?

A 4kW solar panel system costs around £9,500 to buy and install. If you want to include a battery in the installation, this will add around £2,000 to the price, for an overall cost of £11,500.

What is a 4KW solar inverter?

Inverters are one of the essential components of a solar system, and for a 4kW solar system, a 3kW inverter would be sufficient. An inverter is used to supply surge power and usual power. A surge or peak power is the maximum power an inverter can provide for a short time for appliances that need a higher start-up surge.
