The energy produced using fossil fuels is the leading cause behind this rising global warming and climate change. So, if you want to set up a sustainable power setup for your home or business, solar PV installations combined with an energy storage solution are the best! The former utilizes the sun’s energy to produce electricity – reducing your carbon footprint. While the latter stores the produced energy for later use (during low sunlight hours).
Solar PVs combined with an energy storage system offer numerous other benefits. These vary from reduced dependence on fossil fuels and enhanced grid resilience to embracing a greener and more sustainable future. Want to know more about Solar PV and energy storage solutions? Let’s get into this.
Benefits of Combined Solar PV and Energy Storage Systems
There are multiple benefits of solar PV combined with an energy storage solution, such as:
1. Enhanced Energy Resilience and Reliability
If you have a combined solar PV and energy storage solution, you can enjoy energy resilience and have a reliable backup power source. This setup harnesses the power of the sun to produce energy and store it. So, you stay protected from the impact of electricity blackouts and other unforeseen events. Moreover, if you install this system in a commercial and industrial area, you can have all your equipment running, reducing downtime and revenue losses.
2. Demand Charge Management and Peak Load Shaving
Another benefit of this power setup is that it helps you in demand charge management and peak load shaving. Demand charges are fees imposed on consumers when they draw electricity from the grid during peak demand hours. These charges contribute significantly to your overall energy costs. An energy storage solution with solar PV lets you store excess electricity generated during low-demand periods.
So, you can use that stored electricity during peak hours, ultimately reducing the need to draw energy from the grid. This strategy aids you in getting rid of high demand charges in your electricity bill and optimizes the overall usage of solar power. You no longer have to rely on the grid during peak load hours and have all your appliances running smoothly!
3. Time-of-Use Optimization and Energy Cost Savings
The time of day impacts the electricity cost; you get charged more during peak or high-demand hours and less during low-demand hours. So, a combined solar PV and energy storage solution helps you with time-of-use optimization and energy cost savings.
For instance, New Jersey’s on-peak electricity usage is currently 9 am-9 pm Monday through Friday, while the off-peak usage is 9 pm-9 am every day of the week. In high-demand or on-peak hours, you should spend the stored solar energy instead of using grid electricity. Resultantly, you may lessen your dependency on the grid and cut your energy costs.
Design Considerations for Professional Applications
Now I’m going to discuss a few things that you must consider when selecting a solar PV and energy storage solution for your home:
1. System Sizing and Capacity Planning
You should first assess your energy needs and consumption patterns to determine the appropriate size and capacity of the system. Evaluate the available roof or ground space for solar panels and check if it’s suitable to accommodate your power solution. Moreover, you should also take into account your future energy requirements and potential expansions.
2. Integration Techniques and Configurations
Depending on the efficiency, cost, and available space, you should choose the most appropriate PV system technology (monocrystalline, polycrystalline, etc.). Carefully consider how energy storage technologies (such as lithium-ion and flow batteries) can be integrated into the solar PV system. Additionally, make sure that your renewable energy setup seamlessly complements your current electrical system and appliances.
3. Grid Connection and Interoperability
Lastly, you must consider grid connection and interoperability of solar PV and energy storage systems in your area. For this purpose, thoroughly understand and comply with the region’s specific safety standards and codes. This involves familiarizing yourself with local regulations, ensuring compliance with international standards such as IEC, verifying component certifications, etc. You also need to assess your system’s compatibility with the local grid infrastructure and conduct regular inspections.
Financial Analysis and ROI
Purchasing a solar PV and energy storage solution is an upfront investment, so you must have a detailed financial analysis. You should also learn about the time duration for return on investment and more.
1. Cost Considerations and Financing Options
The cost of installing solar PV and energy storage systems can vary depending on several factors, such as system size, location, component quality, and installation complexity. On average, the cost of a solar power system, ranging from six kilowatts to 12 kilowatts, can be around $5,400 to $18,000. However, these figures are subject to regional variations and can be influenced by market conditions. You can finance your off-grid journey through the following options:
- Leasing: Leasing options allow customers to rent solar PV systems and energy storage equipment for a fixed monthly fee. You can pay the amount in installments, eliminating the need for upfront costs.
- Power Purchase Agreements (PPAs): In a PPA, a third-party developer installs, operates, and maintains the solar PV system. The customer agrees to purchase the generated electricity at a predetermined rate, maybe lower than the utility grid’s price.
2. Evaluating Return on Investment
The return on investment duration for your solar power setup depends on many factors. These include system cost, electricity savings, maintenance costs, and system lifespan. However, the average ROI or payback period for your solar power setup can be around 14 years.
3. Government Incentives and Tax Benefits
To encourage the use of solar PV and energy storage systems, governments are providing a range of incentives and tax benefits. Some of these are:
- Federal Investment Tax Credit (ITC): The ITC allows homeowners and even businesses to claim a tax credit equal to a specific percentage of the total cost of their solar PV system. The cutoff for all the solar systems installed till 2022 was 26%. However, now (for installations from 2022 to 2032), the ITC has increased it to 30%.
- Net Energy Metering (NEM): Net metering allows solar PV system owners to receive credit for excess electricity they generate and then feed back into the grid. This credit can offset their future electricity bills, effectively reducing their overall energy costs.
Integration and Management Solutions
Here are the integration and energy management solutions that aid you in identifying and resolving any issue with your renewable energy setup.
- Monitoring and Control Systems: There are various monitoring and control systems that keep an eye on the performance of solar panels, inverters, and other components. They provide real-time data on energy production, efficiency, and system health.
- Demand Response Integration: It refers to the integration of tools with your power system that increase its flexibility and better align the renewable or solar energy supply with the electricity demand.
- Maintenance and Performance Monitoring: You can utilize advanced analytics and monitoring tools to identify any issues or performance deviations. So, you can schedule timely maintenance, troubleshoot problems, and maximize the overall system efficiency and longevity.
