Are There Disadvantages of Using Solar Batteries on Long Island?

The two major disadvantages of solar batteries are high upfront costs and limited lifespan. However, these disadvantages are quickly overshadowed when you consider the benefits.

A backup battery can help you get the most from your solar panels on Long Island. Let’s consider potential downsides, as well as the long-term benefits, so you can make the right choice for your home.

The Cons of a Solar Battery Installation

• Upfront Cost: Battery energy storage systems are complex to design and manufacture. The upfront cost is a significant investment, often between $10,000 and $15,000 in New York.
• Limited Capacity: The average battery system, like a Tesla Powerwall or Generac PWRcell, won’t be able to run heavy-duty appliances for hours at a time. The upper limit is around two hours for a 3-ton central air conditioner.
• Space Requirements: Solar batteries need to be installed on a dedicated wall or floor space, often in a garage or basement, in compliance with strict fire codes.
• Degradation: Battery capacity fades, even with the most advanced battery energy storage systems. Most solar batteries will last between 10 and 15 years.

The Pros of a Solar Battery Installation

• Backup Power: Long Island’s grid is old and susceptible to failure during severe weather events like Nor’easters and hurricanes. A solar battery can provide essential power during a grid outage, even at night when your panels shut down.
• Solar Tax Credits: The New York State Solar Tax Credit can cover up to 25% of the total cost of your system, limited to $5,000. This credit can be applied to solar panels and battery equipment when you install both at the same time.
• PSEG Incentives: PSEG LI also provides incentives, like its Battery Rewards program. You can apply for a direct incentive of up to $250 per kWh of capacity. Depending on the specific program and structure, you could receive discounts on your utility bill for storing energy and allowing PSEG to draw from your battery during periods of peak demand.
• Peak Savings: PSEG’s Time-of-Use rates make electricity more expensive in the late afternoon and early evening. You can use energy from your battery at peak times to further reduce your bill compared to solar panels alone.
• Maximized Long-Term Savings: A solar battery backup system on Long Island can maximize your lifetime solar savings. With a combination of peak-rate offset and the versatility to use free electricity whenever you need it, you can reduce what you pay to the utility company.

Our Expert Thoughts: The value of a battery energy storage system is in its versatility. It doesn’t just help you save more money. It can also power your home in an emergency. It gives you more energy independence and works with your solar panels. If you have an electric vehicle, a solar battery is even more valuable. You could store solar in the day and use it to charge your car at night.
