Since solar power remains dependent on the weather, with power production limited to when the sun shines, rooftop solar users still need electricity from Central Electric.
The graphs below show typical solar power production in various weather conditions throughout the day.
Solar users also usually need power from Central during peak times, as well. These include hot afternoons and cold winter mornings, when many people require electricity at the same time. The two orange vertical bars below show power use during those times of day.
Remember, you can examine your hourly energy use on our member portal. Focus on the energy used between the hours of 10 a.m. and 4 p.m. because those are the hours that the sun is directly over most installations. When the sun is on the horizon, electricity production is greatly diminished.
Look at months in different seasons, such as January, April, July and November, to see how your energy use changes throughout the year. For the most payback, build a system that covers your usage only during those time periods. Build a system that sells back as little electricity as possible as the additional cost of installing more panels than you need to power your home is offset by a lower rate.
