Solar panel battery storage: Pros and Cons
Solar energy is a game-changer for many households. The ability to utilize this abundant and sustainable energy using solar technology helps many people to get rid of the burden of increasing energy costs. Storing solar produced energy grants more energy independence, but it may not be suitable for everyone. Solar storage adds more moving parts, cost and complexity, and homeowners must deal with their residential solar systems. If this turns you away, your standard grid system will reduce the involvement and use the utility grid as a battery backup. It would be best if you still dealt with suppliers and have less autonomy, but for many residents, net metering is a good choice.
Before we rule out backup battery storage systems, let’s take a look at the pros and cons and how to make an informed decision.
Pros and Cons
Pros to Battery Storage
- More incentives to recover system costs
- 24/7 available backup power, ready for the night and emergency needs, so that your home and electrical appliances run smoothly
- Energy is independent of changes in utility rates; i.e., there are no more bills.
- Can work with the grid system to improve efficiency and energy assurance
- Require low maintenance
- Helps to use more of the electricity that panels generate
- Could enable you to take advantage of cheap electricity rate
- Excellent customer service support, if there is any troubleshooting.
- Weather resistance and family friendliness can be anywhere safely be with children and animals.
- Customize system settings digitally and in real-time for maximum savings and personalization
- Reduce your carbon footprint and become a net-zero users
- Noiseless backup energy, unlike generators.
Increasing power outages and increasing rates have become the norm for many residents. Residential solar systems provide a level playing field, but increased storage completely tilts the balance to the side of energy users.
Cons to Battery Storage
- Higher upfront cost than other residential solar systems
- More complexity in estimates to get the backup load right for your needs
- More parts that require annual inspection and maintenance
- Currently pricey, so the payback time may be longer.
- Batteries need replacing during the lifetime of a solar PV system.
- If retro-fitted to the existing solar PV system, you may need a new inverter.
Is storage right for you?
Despite all the advantages, storage may not be suitable for everyone. If you have not experienced a large number of outages, there may be 1-2 short-term ones per year, or you want to pay attention to energy usage, then you may want to obtain a grid system and complete it. For those in both situations, the cost of purchasing a battery backup system may not be worth it.
However, if you are in the following situations, battery storage may be a worthwhile investment:
- Your area is prone to natural disasters
- You often lose power due to unreliable power grids
- You have critical/medical equipment or appliances that must stay working no matter what
- Your energy supplier’s electricity bills and rates are increasing
- You want to reduce seasonal and daily peak costs in your electricity bills
- Reduce your dependence on fossil fuels and further reduce your carbon footprint
Usually, a solar grid system is sufficient for homeowners, but the above scenario classifies energy users as people who need solar energy storage.
Can I do it later?
Investing in a battery backup is an investment that can help you get it faster. Yet another advantage of solar power technology is that you can add to it. If you already have a system or are considering adding one, you can add battery storage later. This can cause some complexity, but you can plan for it when you first install the system. With the sleek and compact design of batteries, most challenges are ineffective. Adding solar storage is getting easier.
