What is A 5kW Solar System?

A 5kW solar system has a power output of 5 kilowatts and can generate an average of around 4000-4500 kilowatt-hours (kWh) of electricity per year. This system consists of several components, including the solar panels, which may vary in size. Typically, a 5kW solar PV system is made up of 12 solar panels. To convert the DC (direct current) electricity generated by the solar panels into AC (alternating current) electricity that can power your home appliances, a 5kW solar inverter is utilized. The inverter is an essential component that plays a crucial role in this conversion process.

In addition to the solar panels and inverter, a battery storage system can be added to the 5kW solar panels system. This allows for the capture and storage of any excess energy produced by the 5kW solar panels during the day. The stored energy can then be used at night or during a power outage, providing you with a reliable backup power source and maximizing the utilization of your solar energy.

The energy output of a 5kW system, once converted by the solar inverter, is roughly equivalent to the amount of energy consumed annually by a household of 4 to 5 people. This makes the 5kW solar system in UK an ideal fit for an average-sized home, catering to the energy needs of a typical family.

Is a 5kW Solar Panel System Right for You?

The answer is yes! If you live in a home with 4-5 people and your average annual consumption is around 4000 kilowatt-hours, a 5kW system is best suited for your household. You can verify your energy consumption by reviewing your energy bill annually. The average consumption of a UK household is approximately 3000 kilowatt-hours per year, indicating that a 5kW solar panel system is ideal for meeting your energy needs.

What Benefits can I Get by Installing 5kW solar system?

  • Payback period of approximately 5 years after installation
  • Nearly free electricity production for the next 20 years
  • Increased property value
  • Enhanced energy independence
  • Minimal maintenance expenses

How Many Solar Panels Are Required for a 5KW Solar Panel System?

The number of solar panels included in a 5kW system can vary based on the size of the panels you use. On average, a 5kW system uses about 12 solar panels, each with a capacity of 405 watts. However, if you opt for smaller panels, such as those with a 350-watt capacity, the total number of panels in your 5kW solar panels system would increase to approximately 14 or 15.

5kW Solar System with Battery Storage System

Adding a battery to your solar PV system is the best option for storing the extra energy produced by your 5kW solar panel system and using it at night. This addition not only reduces your reliance on the grid but also lowers your annual electricity bills. A 5kW solar system with battery in UK allows you to maximize the utilization of the electricity your system generates, preventing any wastage.

It’s important to note that during the 25-year lifespan of solar panels, you may need to purchase a minimum of two sets of solar batteries. However, this cost-effective solution still outweighs the expenses of relying solely on the grid.

How Much Does A 5kW Solar System Cost without Battery Storage System in UK?

Those who do not require backup power often opt for a 5kW solar system without batteries, as it is a more cost-effective choice. Choosing a 5kW solar system with a 5kW inverter, including installation charges, typically costs approximately £6,000 to £7,000 in the UK. However, the cost increases if you decide to add batteries as a backup option. The details regarding the cost of adding batteries are mentioned below.
