As the world moves towards cleaner, more sustainable forms of energy, solar PV systems have become increasingly popular. However, in order to connect to the grid, these systems must comply with certain regulations. Two of the most important regulations for solar PV installations are the G99 and G98 applications. In this blog post, we’ll take a closer look at what these applications are and why they matter.
What are G99 and G98 applications?
G99 and G98 are technical documents created by the UK’s electricity network operators (DNOs) to ensure that all new solar PV systems are safe and compliant when connected to the grid. These documents set out the requirements for connecting renewable energy systems to the grid, with G99 applying to systems larger than 16A per phase, and G98 applying to systems smaller than 16A per phase.
Why do G99 and G98 matter?
G99 and G98 are important because they ensure that solar PV systems are safe, reliable, and efficient when connected to the grid. By complying with these regulations, solar PV installers can ensure that their installations are safe for both the homeowner and the grid, and that they meet the necessary standards for energy efficiency.
What do G99 and G98 cover?
G99 and G98 cover a wide range of technical requirements for solar PV systems, including:
- Connection requirements: G99 and G98 set out the connection requirements for solar PV systems, including the type of connection and the size of the system.
- Protection requirements: G99 and G98 require solar PV systems to have appropriate protection mechanisms in place to ensure the safety of the grid and the homeowner.
- Metering requirements: G99 and G98 require solar PV systems to be fitted with appropriate meters to accurately measure the amount of energy generated and fed back into the grid.
- Testing requirements: G99 and G98 require solar PV systems to undergo a range of tests to ensure that they meet the necessary standards for safety and efficiency.
In summary, G99 and G98 are technical documents that set out the requirements for connecting solar PV systems to the grid in a safe and compliant manner. By complying with these regulations, solar PV installers can ensure that their installations are safe, reliable, and efficient, and that they meet the necessary standards for energy efficiency. So, if you’re planning to install a solar PV system, be sure to check whether you need to apply for G99 or G98 approval.
