Solar panels are not only environmentally friendly but also significantly reduce electricity bills. However, when the sun sets, your panels are not harnessing that great solar energy, and your energy usage is dependent on the grid. But evenings without solar don't have to be a drain on your wallet. Join us as we explore various energy efficiency practices to make the most of solar energy your panels generate during the day and money-saving tips to ease spending during the evening.
Efficient Lighting Solutions
Lighting accounts for a significant portion of a household's energy consumption. Consider switching to energy-efficient LED bulbs to minimize the electricity required after dark. They consume far less energy compared to incandescent or fluorescent bulbs and last longer. When you switch to energy-efficient lighting, you can light your home using the same amount of light for less money. Lighting accounts for around 15% of an average home's electricity use, and the average household saves about $225 in energy costs per year by using LED lighting.
Additionally, the use of motion-sensor lights and timers can be installed to ensure lights are only on when needed. By adopting energy-efficient lighting practices, you not only enhance your energy efficiency but also reduce your overall energy costs, making it a smart and cost-effective choice.
Smart Home Technology
Harness the power of smart home technology to optimize energy usage. Smart thermostats, like the Nest or Ecobee, allow you to schedule heating and cooling according to your preferences and daily routine, ensuring you're not wasting energy while you're asleep or away. Moreover, these devices can be controlled remotely through your smartphone, providing real-time adjustments for energy efficiency. ENERGY STAR smart thermostats are independently certified by EPA-recognized certification bodies, and they can result in significant cost savings. On average, savings are approximately 8% of heating and cooling bills or $50 per year.
Insulation and Weatherization
A well-insulated home plays a crucial role in retaining heat during the colder months and keeping cool air in during the summer. Proper insulation and sealing air leaks can significantly reduce the amount of energy required to maintain a comfortable indoor temperature, which is especially important after sunset. Consider upgrading insulation, weather-stripping doors and windows, and adding storm windows where applicable. Sealing air leaks and adding insulation can lead to up to a 10% reduction in your annual energy bills.
Cook Smart
Efficient cooking practices can substantially impact your energy usage after sunset. Instead of using the oven, consider using an air-fryer or a slow cooker, which are more energy-efficient for meal preparation. When using the stovetop, matching pot and pan sizes to the burner and keeping lids on can speed up cooking and reduce heat loss. By adopting these practices, you can save energy and money while enjoying delicious home-cooked meals.
Energy-Efficient Appliances
When it's time to upgrade or replace your household appliances, opt for Energy Star-rated products. These appliances are designed to consume less energy and water, resulting in lower utility bills. High efficiency washing machines, dishwashers, refrigerators, and HVAC systems are wise choices for reducing energy consumption and making the most of your solar power at night.
Insulate Pipes and Hot Water Heaters
Pipes carrying hot water throughout your home can lose heat, especially when they run through unheated spaces. Insulating your hot water pipes and the hot water heater itself can help retain heat and reduce the energy required to maintain hot water temperatures, particularly during the evening and night. This not only saves energy but also ensures that you have a consistent supply of hot water for your nightly needs.
Thermal Window Coverings
Window coverings can play a significant role in controlling the amount of heat transfer between the interior and exterior of your home. Curtains and blinds can be used strategically to block sunlight during the summer and retain heat during the winter. This can reduce the load on your heating and cooling systems, ultimately saving energy. During summer days, closing draperies on windows receiving direct sunlight can prevent heat gain, reducing cooling costs. In the winter, closing all draperies at night, as well as draperies that don't receive sunlight during the day, can reduce heat loss and improve thermal comfort.
Set Thermostat at Recommended Temperature
For optimal energy efficiency, it's recommended to set your thermostat to a temperature that balances comfort and energy savings. During the winter, lower the thermostat when you're not at home or when you're sleeping, and use sweaters and blankets for warmth. During the summer, raising the thermostat a few degrees and using fans to stay cool can lead to significant energy savings. ENERGY STAR-certified smart thermostats can save an average of 8% on heating and cooling bills annually.
Time-Of-Use Energy Plan: Getting the Most Out Of The Energy Your Panels Create
Many utility companies now offer time-of-use (TOU) energy plans, which provide different rates for electricity at different times of the day. By shifting energy-intensive activities to off-peak hours, homeowners can effectively reduce their energy costs. For example, running your dishwasher or doing laundry during the evening or night can lead to significant savings on your utility bills. Being mindful of the times you use high-energy appliances can further optimize your solar power utilization.
See the sample TOU plan below:
Time of Use Plan for Homeowners with Solar Panels
- Peak Hours (High Energy Costs):
Weekdays: 2:00 PM - 7:00 PM
Weekends: 12:00 PM - 6:00 PM
During peak hours, energy from the grid is the most expensive, so it's best to minimize your usage during this time.
- Off-Peak Hours (Low Energy Costs):
Weekdays: 7:00 PM - 7:00 AM
Weekends: 6:00 PM - 7:00 AM
During off-peak hours, energy from the grid is the cheapest. This is when you should focus on using appliances and performing energy-intensive tasks.
- Solar Generation Hours:
These hours are the times when your solar panels generate the most electricity. The exact hours will vary based on your location and the orientation of your panels. Typically, it's from 10:00 AM to 4:00 PM.
Optimizing Energy Usage:
To maximize energy generated by your solar panels and minimize grid usage, consider performing the following tasks during peak solar hours:
Laundry: Running your washing machine and dryer during peak solar hours can be an excellent choice. These appliances typically consume a significant amount of electricity, and using them when your panels are generating power will reduce your reliance on the grid.
Dishwasher: Similar to laundry, running the dishwasher during peak solar hours can help you maximize your solar energy utilization. Many dishwashers have delay start features that allow you to set them to begin their cycle at a specific time.
Charging Electric Vehicles (EVs): If you have an electric vehicle, try to schedule your charging sessions during the peak solar hours. Many EV chargers have scheduling options that allow you to control when your vehicle charges.
Cooking: Electric stoves, ovens, and countertop appliances like microwave ovens can consume a significant amount of electricity. Cooking meals during peak solar hours can reduce your dependence on grid power.
Pool Pump: If you have a pool, consider running the pool pump during peak solar hours. Pool pumps often run for several hours a day, and by aligning their operation with your solar panel generation, you can save on energy costs.
