Look for trends and patterns – are you producing less energy during certain times of the day or year? Are there any sudden drops in production that might indicate a problem?
Once you have a baseline, you can start identifying potential issues. Shading, as Sarah discovered, is a common culprit. But it could also be something as simple as dirty panels. Dust, pollen, and bird droppings can all reduce the amount of sunlight reaching your panels. Regular cleaning can make a significant difference. Also, consider the angle of your panels. While professional installers typically optimize the angle for your location, significant changes in seasons can impact the optimal angle, and adjustments may be necessary. This proactive approach ensures that your system continues to operate at its peak performance, translating to greater savings and a faster return on your investment. Don't be like Sarah, be proactive!
Decoding Net Metering Policies
Net metering policies are the backbone of on-grid solar systems, dictating how you get credit for the excess energy your panels send back to the grid. Understanding these policies is paramount to maximizing your savings. These policies vary significantly from state to state and even within different utility districts. Some offer full retail rate compensation for excess energy, while others offer a lower wholesale rate or credits that expire at the end of the billing cycle.
The fundamental concept of net metering is that your utility meter runs backward when your solar panels generate more electricity than your home consumes. This effectively allows you to "store" excess energy on the grid and draw it back when you need it, such as at night or on cloudy days. However, the value of that stored energy depends entirely on your local net metering policy. For example, if you receive full retail rate compensation, every kilowatt-hour (k Wh) you send back to the grid is credited at the same rate you pay for electricity. This is the most favorable scenario for solar homeowners.
However, some utilities offer a lower rate, often based on the wholesale price of electricity, which can significantly reduce your savings. It's crucial to understand the specific details of your utility's net metering policy. Research whether credits expire at the end of the month, year, or if they can roll over indefinitely. Also, inquire about any fees associated with net metering, such as interconnection fees or grid access charges. Armed with this knowledge, you can strategically manage your energy consumption and production to maximize your net metering benefits. This might involve shifting energy-intensive activities, like laundry or dishwashing, to times when your solar panels are producing the most energy, further reducing your reliance on grid electricity and maximizing your savings.
