What is the average payback period for a 7kW solar system?

On average, the payback period for a 7kW solar system is between 2.5 to 4 years.

The payback period for a good quality system depends on how much power you use in your home or business. These days, solar-feed tariffs are relatively low in almost every state, and the credits you can receive from your solar system will depend on your solar network.

Self-consumption is, therefore, the best way you can save on your system. The reasoning behind this is that the power your system produces is more worthy to you if you use it yourself than when you send it back to the power grid. In simple terms, every kWh you use is a kWh of electricity you do not need to buy from the grid. Therefore, you can save about 18¢-¢40 on your electricity bill, but this will depend on what your electricity retailer charges you and your location.

How much money can a 7kW solar PV system save me?

The amount of money you can save with a 7kW system depends on how much energy you can use when it is being generated. The more energy you consume, the more money you will save. Typically, you can save about 20 to 30 cents, depending on how much your power bill costs. So, for the power sent back to the grid, you can expect to earn between 5-12 cents per kWh, depending on your solar retailer.

Potentially, you can save between $400 to $700 per quarterly bill. With such savings, you will significantly reduce your monthly electricity bills.

7kW solar system with battery storage

Whether you want to install a new system or you would like to upgrade your existing one, installing battery storage has become much easier than before. For existing solar energy systems, AC coupling has made it extremely easy to hook battery storage systems to your property. The battery system connects directly to your home’s power supply.

For the 7kW solar system, you will need a battery with at least 19.6kWh in capacity. However, the price of batteries differs depending on their quality, brand, and provider. Before choosing a particular battery system, it is paramount to get several quotes from different providers. Once you know the average prices, you can select a system that meets your needs.
