Maximizing the Benefits of Solar Panels: Beyond Home Heating and Lighting
Photovoltaic (PV) systems have become increasingly popular among homeowners and businesses alike, not only for their environmental benefits but also for cost savings. While many are familiar with the basic functions of solar panels, such as heating water and regulating household temperature, there are additional ways to utilize the excess electricity generated by these systems. This article explores various applications of solar-generated electricity, providing insights into how you can maximize the benefits of your PV setup.
Understanding Grid Tied Systems and Excess Electricity
Unless your home is fully off-grid and equipped with a large battery backup system, the solar panels you install are typically connected to a grid-tied system. In this setup, all the power produced by your solar panels is directly fed into the local power company grid. The energy you generate is shared with the wider community, and if your system produces more electricity than you consume, the utility company may issue a credit.
This credit applies primarily to the electricity you consume after sundown. Once the solar panels stop generating electricity, any further usage comes from the utility grid. However, if you have a significant battery storage system, you can use the excess electricity to charge the battery during the day, which can then power your home at night. This method not only ensures a continuous flow of power but also helps you earn credits from the utility company.
Applications of Excess Electricity
When your solar panels produce more power than you consume, there are several ways to utilize this excess electricity:
Home Heating and Cooling Systems
Heating water and regulating the temperature of your home are two of the primary uses for excess solar-generated electricity. Using this energy can significantly reduce your utility bills and lower your carbon footprint. However, if you have a heat store tank, battery, or grid connection, you can store or harness this energy more effectively. Heat store tanks can be used to pre-heat hot water, making your overall heating system more efficient.
Electric Vehicle Charging
Electric vehicles (EVs) are becoming more mainstream, and the excess electricity from your solar panels can be used to charge them. Installing a two-way EV charger allows you to feed back into the grid when there is excess power. This dual functionality not only ensures that your EV is charged when you need it but also generates credits from the utility company. Additionally, if you have a fossil fuel car as a backup, the excess electricity can be used to charge both vehicles, reducing dependencies on grid power and lowering costs.
Business Applications
For businesses with solar panels, one smart solution is to install EV charging stations in the car park. This not only provides an advantage for employees but also positions your business as a green and forward-thinking entity. The excess electricity can be used to charge these vehicles, reducing operational costs and aligning with environmental goals.
Conclusion
The use of excess electricity from solar panels extends far beyond basic home heating and lighting. Whether you are a homeowner or a business owner, there are numerous innovative ways to leverage this energy. From heating and cooling systems to electric vehicle charging solutions, the possibilities are vast. By harnessing the full potential of your solar panels, you can achieve significant cost savings while contributing to a more sustainable future.
