A Comprehensive Guide to Solar Energy Storage Solutions
With the increasing trend towards renewable energy resources, solar power generation has gained significant attention around the world. A major part of this development lies in the effective utilisation of energy storage systems. But with a myriad of solar power storage options available, how does one choose? This guide is designed to help. Let’s dive into the world of solar energy storage solutions!
☀️ Solar Power and Its Importance
For those unfamiliar with the concept, solar power refers to energy fetched from the Sun’s rays. This renewable and clean energy source reduces reliance on fossil fuels, thereby contributing to the reduction of greenhouse gas emissions. According to IRENA, solar energy usage could potentially prevent up to 6 billion tonnes of carbon emissions each year by 2050.
💬Salvatore Vinci from IRENA said that “The future energy system will be dominated by renewables”
🔋 Why Use Solar Energy Storage?
Solar energy isn’t available during the night or on cloudy days. Hence, solar energy storage systems are crucial for harnessing solar power outright. They store excess energy generated during the day for use when needed, ensuring a consistent energy supply and reducing dependency on the grid. The Clean Energy Council states that energy storage will be a major factor in global energy market trends in the near future.
⚙️ Types of Solar Energy Storage Solutions
Battery Storage
A popular option for solar energy storage is battery storage systems like Tesla Powerwall, Sungrow, and Stiebel Eltron. These systems involve storing energy in rechargeable batteries for later use. Crucially, these systems can provide backup power in case of power outages.
Thermal Storage
Thermal energy storage systems, like useful for storing heat or cold energy for later use. These systems store energy during off-peak times and release it during peak demand periods, reducing the cost of energy consumption.
🔍 Factors to Consider While Choosing Solar Energy Storage
- 🔹 Storage capacity: Reflects the total amount of electricity that a solar battery can store, measured in kilowatt-hours (kWh). Deciding on capacity depends on one’s energy needs.
- 🔹 Power rating: The amount of electricity a battery can deliver at one time, measured in kilowatts (kW). The Clean Energy Council suggests considering a battery’s capacity and power rating collectively.
- 🔹 Depth of Discharge (DoD): This refers to the percentage of the battery’s energy that has been discharged relative to the overall capacity. Some batteries have an optimal DoD where the battery should be discharged for maximum efficiency.
- 🔹 Lifespan: This is typically impacted by the number of cycles (charging and discharging) the battery completes. A product from a reputable manufacturer like Tesla or Sungrow will typically last longer.
