At We Are Going Sustainable, we are always looking for the most effective and sustainable ways to make your home or business more sustainable. A frequently discussed topic in this context is the use of a home battery, especially in combination with solar panels. But is a home battery a good idea for you? Let's take a closer look at the pros and cons.
The Phaseout of the Saling Scheme.
Earn from returning power that you generate with solar panels generation is limited by the phasing out of the energy-saving scheme. However, the net-metering scheme for solar panels will remain in place for now, as the government's original plan to phase it out was rejected by the Senate. Phasing out the balancing scheme would mean that you would receive less compensation for the electricity you feed back into the electricity grid. Is it then a wise choice to store this power in a home battery?
Benefits of A Home Battery:
1. Using Self-Generated Energy Directly:
- With a home battery, you store the self-generated solar energy and can use it immediately when you need it, even at night or on cloudy days.
2. Reduced Dependence on the Electricity Grid:
- By using your own generated energy, you become less dependent on the power grid and fluctuations in energy prices.
3. Energy Bill Savings:
- Using stored energy can lead to significant savings on your energy bill, especially during peak hours with high rates.
4. Relief of The Electricity Grid:
- A home battery can unburden the electrical grid by reducing the amount of power you feed back. This is especially useful at times of high demand and load on the grid.
Disadvantages of A Home Battery:
1. High Initial Cost:
- Buying a home battery is a big investment. Prices vary, but on average it is between 4,000 and 5,000 euros for a battery with a capacity of 6 kWh.
2. Limited Storage Capacity:
- Home batteries have limited storage capacity, which means you can't store all the solar energy you produce for later use, especially in the winter months.
3. Environmental Impact of Production:
- The production of home batteries has an environmental impact, mainly because of the use of metals such as lithium, copper and nickel.
Economic Considerations:
Thijs ten Brinck, energy specialist and founder of WattisDuurzaam, emphasizes that a home battery is not necessarily sustainable because of the environmental impact of its production. However, he points out that you can also look at a home battery from an economic point of view. After all, you pay less energy tax because you don't have to buy as much energy from the grid.
Mariken Stolk of Milieu Centraal adds that the percentage of self-use solar power can already rise to 35 percent by simple actions, such as turning on the dishwasher or washing machine at sunny times.
Considerations for Your Decision:
- Energy consumption: How much energy do you consume and at what times of the day?
- Cost and Payback Period: What are the initial costs and how long will it take to recover them?
- Environmental Impact: Are you willing to accept the environmental impact of producing a home battery?
- Available Space: Do you have enough space to install a home battery?
Conclusion:
A home battery can be a smart investment for those striving to become more self-sufficient, save on their energy bills and reduce their carbon footprint. However, cost, storage capacity and environmental impact are important factors to consider.
It is advisable to seek advice from a professional and evaluate your specific situation before making a decision. This will help you determine if a home battery is a good choice for your home or business.
