Find out everything you want to know about solar-plus-storage systems, from general terms, maintenance, and costs.
What is a solar-plus-storage system?
A solar-plus-storage system combines solar panels with energy storage, typically in the form of batteries. This setup allows you to generate electricity from sunlight and store excess energy for later use. It enhances the efficiency and reliability of solar power, providing a consistent energy supply even when the sun isn't shining.
How does a solar-plus-storage system work?
Solar panels convert sunlight into electricity, which is either used immediately by your home or stored in solar batteries for future use. The system's inverter converts the DC electricity generated by the panels into AC electricity, which is compatible with household appliances. The storage component ensures that you have access to power during cloudy days or at night and can also provide backup power during grid outages.
What are the benefits of a solar-plus-storage system?
- Energy Independence: Reduce reliance on the grid and protect against rising energy costs.
- Backup Power: Maintain electricity during power outages, ensuring critical appliances stay operational.
- Maximized Energy Usage: Store excess solar energy for use when production is low or demand is high.
- Environmental Impact: Decrease your carbon footprint by using more renewable energy.
- Financial Incentives: Benefit from tax credits, rebates, and potential savings on energy bills.

Are solar-plus-storage systems cost-effective?
While the initial investment for a solar energy system for your home can be significant, the long-term savings on energy bills and potential financial incentives can make it cost-effective. Additionally, the decreasing costs of solar panels and batteries are making these systems more affordable. In fact, the price of lithium batteries has decreased 97 percent over the past three decades. It's important to consider your specific energy needs and usage patterns to determine the potential return on investment.
How long do solar batteries last?
Battery lifespan depends on the type, usage, and maintenance. Most lithium-ion batteries, which are commonly used in solar-plus-storage systems, have a lifespan of 10-15 years. Proper maintenance and usage can help extend the life of your batteries. Make sure to always check a battery manufacturer’s warranty, as this will give you a good indication of the battery’s likely lifespan.
Can I add storage to my existing solar panel system?
Yes, many existing solar panel systems can be upgraded with battery storage. It's advisable to consult with a professional to assess compatibility and ensure a seamless integration with your current setup. Contact a lithium battery expert at RELiON for questions about your specific system.
How much storage capacity do I need?
Storage capacity needs vary based on your energy consumption patterns, the size of your solar panel system, and your goals (e.g., backup power versus complete energy independence). An energy audit can help determine the appropriate capacity to meet your needs. Use this free calculator to help you establish how much energy storage you will need.
Do solar-plus-storage systems require maintenance?
Solar-plus-storage systems generally require minimal, if any, maintenance. Regular inspections, keeping panels clean, and ensuring that the batteries are operating efficiently are typically all that’s needed. It is important to note that while lithium batteries are maintenance free, lead-acid batteries often require watering and checking on the valves. Whichever system you have or select, it is advisable to follow the manufacturer’s guidelines.

Are there incentives available for installing a solar-plus-storage system?
Yes, various financial incentives are available, including federal tax credits, state rebates, and utility-based programs. One example is the Federal Investment Tax Credit (ITC) for solar and energy storage systems. These incentives can significantly reduce the initial cost of installation. Check with local authorities and energy providers to explore available options.
How do I get started with a solar-plus-storage system?
Begin by evaluating your energy needs and goals. Research reputable solar-plus-storage providers, manufacturers and installers, if needed. Financing options, such as loans or leases, can also help make the investment more manageable. Get in touch with a RELiON solar-plus-storage expert today to move forward with your system.
