Determining the required amount of kWh for your household depends heavily on your personal energy needs and goals. Whether you aim to save costs by taking advantage of varying daily prices or to become self-sufficient, selecting the right battery system is key.
Choosing for Cost Savings
For households looking to maximize the benefits of fluctuating daily prices, a 10 kWh home battery system is a wise choice. With lower costs per kWh, you can achieve a higher return on your energy investment. This system allows you to store energy when prices are low and use it when prices are higher, significantly saving on your energy bill.
Aiming for Self-sufficiency
If becoming self-sufficient is your main goal, then moving to a 5 kWh battery system is a significant step. With such a system, you can increase the efficiency of your energy usage from about 30% to 70%. This means you are less dependent on the energy grid and make more use of the energy you produce yourself, contributing to sustainability and energy independence.
What Fits Your Household?
It's important to note that the recommendations above are based on the average energy consumption of a household, which is around 3000 kWh per year. If your household consumes more energy, opting for a larger 10 kWh battery system is advisable. This ensures you have enough capacity to efficiently manage your energy needs and meet your goals for cost savings or self-sufficiency.
