With the rising fear of how individuals and industries are going to fuel their future in the absence of finite fossil fuels, renewable sources of energy is the answer. Power companies are focusing on how to slowly and gradually convert to sustainable energy sources so that the world keeps running and propelling forward. One of these renewable sources of energy is Solar Power which has become so popular lately that its market has doubled in the past 3 years.
With the increasing usage of solar power, another renewable energy tool has also become popular: The Solar Battery. Solar batteries store energy by converting DC energy produced by Solar Panels into AC Power for later use. They are often installed with solar panels and serve as ‘Solar-plus storage’ for your office or home.
Understanding the Solar Energy System
Solar Energy System usually consists of Solar Panels, an inverter, a supportive gear to mount the Solar Panel to your roof and a monitoring system that helps you check the amount of power being produced.
Many small offices and houses use an electricity-grid which is typically attached to their Solar Energy System and is used to store excess energy. This Electricity-Grid is also known as a ‘Grid-tied’ and the excess energy stored in it can be drawn back when you need it.
When electricity is sent back to the grid, you can receive ‘credits’ on your utility bill. If in the future, your usage exceeds the electric power that you are producing, you can always utilize credits instead of paying more for your utility bill. This process is popularly known as Net Metering.
When choosing a battery, you should know what to look out for. A deep understanding of how solar batteries work is imperative in this regard and can help you make informed decisions.
How to evaluate a Solar Battery
- Depth of Discharge (DoD) of a battery is the power which has been utilized. If 100 percent of a battery is utilized, its life will be reduced. The higher your battery’s DoD, the more capacity you will be able to use. Luckily a number of manufacturers mention the maximum DoD required for optimal performance so you can check it before purchasing it.
- You should also check the Capacity and Power rating of your battery to ensure it gives can work for longer hours. Capacity is measured in kilowatt hours (kWh) and refers to the size of your battery whereas a Power rating is indicative of the amount of electricity your battery can deliver at a time and is measured in kilowatts (kW)
- Like all other batteries, Solar Battery’s capacity to hold power also degrades over time.
