As the market adjusts to solar panels and batteries becoming more commonplace, we’re all concerned with the cost, pricing, and return on investment. At West Coast Solar, we understand if a solar battery bank seems like a costly investment, but if you review your energy use you may be surprised at the savings you could find when you use a battery bank. In this post, we’ll be sharing how solar storage works and the estimated cost, depending on your area.

Understanding Solar Storage

The first place you’ll want to start before purchasing a solar battery for your energy storage is how much it’s going to cost. In general, you can think about the cost of a solar battery in two ways. The first is in gross cost. As of 2018, solar batteries can run anywhere from $5000-$10,000 gross cost per unit. Alternatively, you could consider the kilowatt per hour (kWh) cost, which can range between $375-$825 per hour.

Remember to consider how the batter will function and the type of battery. For example, a battery that’s intended to function off-grid to store energy will typically cost more than a battery built to function tied into the grid.

If you’re concerned with the pricing of solar batteries, take note of how solar panel pricing is steadily decreasing. As solar systems are becoming more common and technology advances, the market price will find a steady range. We expect solar batteries to do the same.

Check to see if the battery you plan on purchasing has a built-in inverter. An inverter helps manage the flow of energy to and from your battery. Inverters will raise the price of the battery, but it will also offer you an efficient management system for energy within your battery. The cost is worth it to most purchasing a solar battery for their home or business.

Would Installing A Solar Battery Be Worth It For You?

You want to look at the comparative cost between battery use and no battery use on your kilowatt per hour rate. If you pay the same kWh rate no matter the time of day, you may not necessarily need a battery. On the other hand, if your kWh rate does fluctuate throughout the day, a battery could store energy during low-rate times, and then give you energy during peak-rate times for the low-rate price. This instance would be a great reason for a battery addition to your home or business. Make sure and watch out for these other rate hikes:

  • Demand Charges: extra fees based on electricity use or time of use
  • Reduced/No Net Metering: if your electricity provider offers credit at “wholesale” for electricity, it may be advantageous to store the energy at your house instead of purchasing it from the grid at “retail.”

Prepare Your Solar System Now

If you already have a solar power system installed on your home or business, you want to make sure it’s ready to implement solar batteries. This means calling your solar technician from either your installation company or through your operations and maintenance services to ensure you can add a battery bank to your system.

Do You Need Solar Storage Financing?

Financing for a solar battery bank or other solar storage options is relatively the same as financing solar panels. You have three options: purchase outright, lease the battery, or acquire a loan for the battery. Depending on your financial situation, you will need to determine which purchase path is right for you.

Does The Solar Investment Tax Credit Cover Batteries?

If you install a solar system and it includes solar batteries, the tax credit does cover them. However, if you install batteries separate from your system install, you will need to find incentives or initiatives elsewhere.
