What is Solar Battery Storage

In 2024, Solar battery storage remains popular in Scotland with people who already own solar panels or those new in the market looking to get the most from their PV system.

Battery storage also known as solar energy storage, home battery storage or simply solar batteries, it refers to the technology used to store excess electricity generated by solar panels for later use.

As the user, you can either store electricity generated by your solar panels in your battery system for later use or sell the stored energy back to the grid, ideally at times where the payment is higher and your likelihood of needing to use to the excess energy is lower.

During the last solar boom around 20 years ago, the panels and equipment being installed were not very advanced and wasteful in various ways. Older panels were clunky and normally had half of the output than the panels available in 2024. There were certain tariffs back then that paid incredibly well, so most homeowners and even installers, didn’t spend enough time talking about ways to optimise performance other than the standard conversation relating to shade and hoping your roof orientates well to south. These days the tariffs are less competitive and to be honest, in terms of the rate paid when selling back to the grid you don’t get much at all! 

So the name of the game is system optimisation and making sure your PV system performs at its best with battery storage and a compatible inverter is the safe bet to see solid returns. The rate paid per unit when sold back to grid is still better than nothing, however, realistically the aim should be to generate, store and properly use any power so that your energy bills are reduced by at least 80-90%. 

In some cases, people can exceed this and then sell energy back to the grid, this is the ideal scenario. But for most homes in Scotland, especially those who work during the day and see a natural increase in electricity demands later in the day and the evening, battery storage is the way to go. Any energy your panels generate during the day is stored for use at night or another time. This results in zero waste and lower energy bills. On the same premise, if you are retired and live alone or with a partner, chances are your electricity usage will be carried out mostly during daylight that you can power from your solar panels throughout the day and you will have less need for battery storage.

How Does Battery Storage Work?

Solar battery storage systems work by capturing and storing excess electricity generated by solar panels during periods of sunlight for later use. Here’s a step by step overview of how these systems typically operate for use on homes and small business premises in Scotland:

  1. Solar Panels Generate Electricity: Solar panels, typically installed on the roof or in an open area with good sunlight exposure, absorb sunlight and convert it into electricity through the photovoltaic effect. This electricity is generated in the form of direct current (DC).

  2. Charge Controller: The electricity produced by the solar panels flows through a charge controller, which regulates the voltage and current to ensure that the batteries are charged safely and efficiently. The charge controller prevents overcharging or over discharging of the batteries.

  3. Battery Storage: Excess electricity generated by the solar panels that is not immediately consumed by the home or business is directed to a battery storage system. This stored electricity is stored in rechargeable batteries, typically lithium-ion or lead acid batteries, for later use.

  4. Inverter: When electricity is needed to power appliances, lights, or other devices in the home or business, the stored energy in the batteries is converted from DC to alternating current (AC) by an inverter. AC electricity is the standard form of electricity used in most buildings.

  5. Energy Management System: Many solar battery storage systems include an energy management system that monitors energy production and consumption in real-time. This system optimises the use of stored energy, ensuring that electricity is available when needed while maximising the use of solar generated power.

  6. Grid Connection (Optional): In some cases, solar battery storage systems may be connected to the grid. This allows excess electricity to be exported to the grid for credit or compensation and enables the system to draw electricity from the grid when solar production is low or during peak demand periods.

  7. Backup Power (Optional): Some solar battery storage systems are equipped with backup power capabilities. During grid outages or blackouts, the system can automatically switch to battery power, providing uninterrupted electricity to critical loads in the home or business.

Overall, solar battery storage systems provide a way to capture and store solar energy, enabling greater energy independence, increased self-consumption of solar power, and backup power capabilities.

Benefits Of Solar Battery Storage

Solar battery storage offers several benefits, including:

Solar battery storage has been proven to improve performance of existing solar panels by up to 70%.

By storing and using solar energy rather than purchasing electricity from the grid, homeowners can significantly reduce their electricity bills over time.

Battery storage provides a better and often quicker return on investment, as well as more longer term savings and returns.

Solar battery storage allows homeowners to store excess energy generated by their solar panels for later use, reducing reliance on the grid and providing greater energy independence.

Time Of Use Tariffs and Battery Storage Systems

Time-of-use (TOU) tariffs and battery storage systems complement each other well, offering several benefits:

Time of use tariffs charge different electricity rates based on the time of day, with higher rates during peak hours and lower rates during off-peak hours. Battery storage allows you to store electricity during off-peak times when rates are lower and use it during peak times when rates are higher, maximising cost savings.

Battery storage systems enable you to shift energy consumption away from peak hours, reducing your reliance on grid electricity during times of high demand. This helps alleviate stress on the grid and may even qualify you for incentives or rebates from utility companies.

Battery storage systems offer flexibility in managing energy usage, allowing you to optimise your electricity consumption based on TOU tariffs and other factors. With the ability to store and release energy as needed, you gain greater control over your energy usage and costs.

Overall, combining time-of-use tariffs with battery storage systems offers a comprehensive solution for managing electricity costs, reducing reliance on the grid, and promoting sustainability.
