So, you’ve got panels on the roof, soaking up the sun. You’re likely seeing smaller electricity bills, and you’re doing your bit for the planet. But have you ever wondered if you’re really getting the most out of your system? Maybe you’ve seen the basic numbers on your inverter or a confusing graph from your energy provider and thought, “There has to be more to this.”
You’re not alone. Across the country, many who have embraced solar are asking the same questions. They’re sharing their frustrations and their wins, wondering why their mate down the road seems to be saving more or how to spot if something’s not quite right with their setup.
The essentials
When we talk about your solar setup, there are a few key bits and pieces working together. You’ve got your solar panels on the roof, then your inverter, and your electricity meter, which is now likely a smart one keeping track of how much power you’re using from the grid and how much you’re sending back.
When you start thinking about monitoring, there are a few numbers that solar owners often keep an eye on. There’s the energy generation, which is the amount of power your panels are actually making. Then, there’s energy consumption, which is how much electricity your household is using. A big one for savings is self-consumption, which is the amount of your own solar power you use directly. If you’re feeding extra power back to the grid, you’ll be interested in your feed-in tariff (FiT) and the payment you get for that. And lastly, there’s grid import, which is the electricity you still need to buy from your energy provider.
These are the key elements and numbers we’ll be referring to as we dig deeper into how we are really keeping tabs on their solar and making the most of it. You’ll find more detailed explanations of these elsewhere online, but this gives us the quick lay of the land.
When it comes to seeing what your solar’s up to, you’ve generally got a few options. Most solar systems come with some sort of inverter monitoring. This might be a little screen on the inverter, a website you can log into, or an app on your phone. These systems usually show you how much power you’re currently making and might give you some summaries for the day, month, or year.
Then, there are your smart meters and the energy provider’s online portal or app. These are getting more common across the country and can show you how much energy you’re pulling from the grid and how much you’re feeding back. This is the official data, but often it’s not in real-time and can be a bit clunky to navigate.
Finally, there’s a whole range of dedicated solar monitoring devices and apps from other companies. These often plug into your system or smart meter and promise more detailed, real-time information and fancier analytics.
The art of effective solar monitoring
· Establish a baseline: For the first weeks (or months) after getting solar, observe your generation and consumption without making changes. Note down typical daily and weekly generation figures in different weather conditions. This gives you a benchmark to compare against later. Tip: Factor in typical seasonal weather patterns in your region when establishing your baseline.
· Check your inverter regularly: Make it a habit to quickly check your inverter’s display or app for any error messages or significant drops in power generation, especially on sunny days. Be mindful of common error codes for your specific inverter model.
· Review your energy provider’s data: At least monthly, log into your energy provider’s portal to see your import and export figures. Compare these to your inverter’s generation data to understand your self-consumption rate. Pay close attention to how your FiT is applied and if it aligns with your expectations based on your state’s regulations.
· Set up alerts: Many inverter apps and dedicated monitoring systems allow you to set up alerts for things like low generation or high grid import. Use these features to catch potential issues early.
· Track your self consumption: Aim to maximise the amount of solar energy you use directly. Monitor your consumption patterns and try to shift energy-intensive tasks to coincide with peak solar production times. Consider using timers for appliances to automate this process based on typical sunny hours in your area.
· Investigate discrepancies: If you notice significant differences between your inverter’s generation data and your energy provider’s export data, or if your self-consumption seems unusually low, investigate further. This could indicate a system issue or a need to adjust your energy usage habits.
· Document your findings: Keep a simple log of your monthly generation, consumption, self-consumption, and any issues you’ve noticed. This historical data can be invaluable for identifying long-term trends or potential system degradation.
· Engage with the community: If you’re unsure about something you’re seeing in your monitoring data, don’t hesitate to ask for advice in online forums. Other solar owners have likely encountered similar situations.
· Consider a dedicated monitoring system: If you want more granular data and insights, explore third-party monitoring solutions that are popular and well-reviewed within the community.
· Don’t ignore warning signs: If your inverter is consistently showing errors or your generation is significantly lower than expected, contact your original installer or a qualified solar technician for a professional inspection.
