Solar batteries
Solar batteries offer users efficiency and cost savings by allowing homeowners to store generated solar energy and use it when the sun is not shining. This maximizes the consumption of sustainable energy and reduces reliance on the electricity grid, leading to lower energy costs. Moreover, a solar battery helps avoid peak loads on the grid and contributes to a more stable energy supply. As a result, investing in a solar battery is not only financially advantageous but also a step toward energy independence and more sustainable energy management.
What are solar batteries?
Solar batteries store excess solar energy for later use. This makes them ideal for both off-grid and on-grid applications. With a solar battery, households can use energy when solar power is unavailable, providing greater independence from the electricity grid.
Solar battery brands
ESTG offers several brands of solar batteries in its range. These energy storage batteries can be broadly categorized into high-voltage and low-voltage batteries and are available in different power classes. The brands in our assortment include:
Benefits of batteries for solar panels
- Security during power outages: Always have access to power, even during outages.
- Efficient energy use: Store excess solar energy for use when solar panels produce less or no energy.
- Cost savings: Reduced dependence on the electricity grid lowers energy costs.
- Environmental friendliness: Efficient use of generated solar energy and less dependence on polluting energy sources.
- Energy independence: Reduces reliance on the public power grid.
- Reduced peak loads: Helps stabilize the electricity grid during peak hours.
Disadvantages of solar batteries
- Complexity: Requires a hybrid inverter or additional equipment.
- Higher initial costs: Purchasing a solar battery is expensive and does not immediately yield financial benefits.
- Space: A solar battery takes up more space and must be safely installed.
What battery capacity do I need?
The capacity of a battery is measured in kilowatt-hours (kWh). Modern battery systems are modular and scalable, allowing them to be easily adjusted to your needs. The right capacity depends on the daily electricity consumption of a household, which averages around 20 kWh per day, and the amount of electricity consumed during peak hours.
Is a solar battery worth the investment?
Although the initial costs are high, solar batteries offer significant benefits in terms of energy savings and independence. The cost of a solar battery varies widely depending on the capacity and brand. Typical prices range from around 700 euros to more than 10,000 euros for larger off-grid systems. The payback period is usually between 7 and 10 years.
