Installing a solar system is often associated with the promise of reduced electricity bills. However, some homeowners find that their bills remain high even after going solar. Understanding why this happens is crucial in optimizing solar system performance and truly capitalizing on solar energy savings. Let’s explore the factors that might contribute to this and how to address them.
Assessing Solar System Performance
First and foremost, it’s essential to ensure that your solar system is functioning optimally. Regular solar system monitoring, maintenance and servicing are key to this. If your system isn’t performing as expected, it could be due to several reasons, such as dirty solar panels, inverter issues, or shading from new obstructions. Scheduling regular check-ups can help identify and rectify such issues.
Excess Solar Energy and Its Utilization
Many solar systems generate more energy than a household consumes during peak sunlight hours. This excess solar energy often goes back to the grid, and you might be credited for this via a solar feed-in tariff. However, if your tariff rate is low, you won’t see as significant a reduction in your bills. It’s worth reviewing your plan and considering if a different tariff arrangement might be more beneficial.
Understanding Time of Use Consumption
Time of use (TOU) rates mean that the cost of electricity varies throughout the day. Electricity is often most expensive during peak hours, which are typically in the evening when solar production is low. This can result in higher bills if you’re using a lot of power during these expensive times. Being mindful of when you use your electricity can help manage costs better.
Load Shifting and Battery Energy Storage
Load shifting involves using appliances during off-peak hours to take advantage of lower rates. Additionally, investing in battery storage allows you to store excess solar energy generated during the day to use during peak hours. This process, known as battery energy soaking, can significantly reduce your reliance on the grid and lower your bills.
The Role of Solar Tariffs
Solar tariffs play a crucial role in the economics of solar energy. These tariffs, set by your energy provider or government, determine how much you’re credited for the excess solar energy you feed back into the grid. A low tariff rate can mean that you’re not getting the full financial benefit of your solar system’s output.
Conclusion
High electricity bills despite having a solar system can be a frustrating experience. However, by closely monitoring solar system performance, understanding your energy usage patterns, and considering the addition of battery storage, you can maximize the benefits of your solar investment. Regular maintenance and being aware of the finer details like solar tariffs and TOU rates are key to ensuring your solar system is as beneficial as it should be in reducing your energy costs.
