Solar System Batteries
Solar system batteries are one of the most critical components for the continuous and efficient use of electricity generated in solar energy systems. While solar panels only produce energy during the day, batteries store this energy, ensuring its use at night or when the sun isn't shining. Energy storage capacity, cycle life, efficiency rating, and safety features play a decisive role in the overall performance of solar systems.
Solinved is a leading brand in solar battery technologies, boasting domestic production power, advanced engineering infrastructure, and long-lasting lithium battery solutions. In this article, we will examine in detail what solar batteries are, what their types are, what criteria determine their prices, and what solutions Solinved offers in this area.
What is a Solar System Battery?
A solar system battery is an energy storage unit that stores DC electrical energy generated from solar panels and returns it to the system when needed. This allows the solar system to provide uninterrupted power not only during the day but whenever needed.
Solar batteries:
Provide energy during power outages,
Continues system operation during low-sunlight hours,
Reduces grid dependency,
Reduces energy costs.
Solinved's superior lithium battery solutions are designed to offer the highest storage efficiency in solar systems.
Solar System Battery Types
Solar batteries are divided into several different categories based on their chemical structure and performance characteristics. Each battery model has different advantages, areas of use, and economics.
1. Lead-Acid Batteries
This is the classic battery type used for many years.
It is notable for its low cost, but its cycle life is limited. It requires regular maintenance.
Features:
Affordable initial cost
Heavy-duty construction
500–800 cycle life
Low resistance to deep discharge
Usage Area: Temporary energy needs or small systems.
2. Gel Batteries
An improved version of lead-acid batteries. The electrolyte is gel-form and leak-proof.
Features:
Maintenance-free
Longer lifespan than lead-acid batteries
Medium-level efficiency
Applications: Caravans, boats, small off-grid systems.
3. AGM (Absorbed Glass Mat) Batteries
The electrolyte is impregnated within glass fiber layers. More durable than lead-acid batteries.
Features:
Vibration resistant
Sealed design
Fast charging capability
Applications: Mobile and light off-grid applications.
4. Lithium (LiFePO₄) Batteries – Solinved's Recommended Technology
This is the most preferred battery type in modern solar systems.
It surpasses other battery types in both efficiency and durability.
Features:
Cycle life of approximately 6,000 cycles
High energy density
Low weight
Up to 95% efficiency
Maintenance-free
Stable operation over a wide temperature range
Solinved Lithium Batteries offer the highest performance in solar energy systems thanks to their advanced cell structure, safety circuits, and intelligent battery management system (BMS).
Things to Consider When Selecting a Solar Battery
Choosing the right battery for use in a solar system directly impacts the system's lifespan and efficiency. The following are key criteria in the selection process.
1. Capacity (Ah)
A capacity appropriate to daily energy consumption should be selected.
If the battery capacity is low, sufficient energy cannot be provided at night; if the capacity is too high, the system becomes unnecessarily expensive.
2. Voltage (12V / 24V / 48V)
48V is generally preferred in large-scale systems.
Solinved lithium batteries are compatible with different systems with their wide range of voltage options.
3. Cycle Life
Lithium batteries have a lifespan of 10–15 years, while conventional batteries can last half that long.
4. Depth of Discharge (DoD)
Deep-discharge-resistant batteries are more efficient.
Solinved lithium batteries operate safely up to 85–90% deep discharge.
5. BMS (Battery Management System)
A BMS is a mandatory component in professional solar systems.
Solinved's advanced BMS structure:
continuously monitors cell balance,
provides protection against overcurrent and temperature risks.
Factors Affecting Solar Battery Prices
Solar battery prices are not fixed. They vary depending on various factors such as brand, capacity, technology, and lifespan.
1. Technology Type
While lithium batteries have a high initial cost, their long lifespan and low losses make them more economical in total cost.
2. Capacity
As capacity increases, the price increases, but choosing the right capacity is crucial to meet energy storage needs.
3. Cycle Life
Longer-lasting batteries offer higher initial costs but are more economical to use.
4. Integration
Batteries that are fully compatible with inverters, solar drives, and chargers offer higher safety. Solinved battery solutions offer a price-performance balance thanks to their long life, high efficiency, and robust BMS infrastructure.
