Is It Worth Getting a Tesla Powerwall? | Solar Panels, Battery Storage, Roofing, HVAC

Across the USA, since 2015, the number of US homes with installed solar panels increased by an average of 32% a year. Would you like to join the ranks of these homeowners who are benefitting from solar power with a battery backup?

Battery storage works well with both grid power and solar energy sources, helping you save on your electricity bill during the peak hours when electricity is most expensive. The only question is, “Which battery suits you best?”.

Keep reading to find out if the Tesla Powerwall is a good fit for your home.

What Is a Tesla Powerwall?

The Tesla Powerwall is a wall-mounted battery that stores electricity from the grid or solar panels for later use. It automatically detects power outages and can keep your lights on and your appliances running for hours without electricity.

When combined with solar panels, the Tesla Powerwall can keep your appliances running for days on end without using any electricity from the grid.

The Powerwall produces no noise or emissions and requires little upkeep.

How Much Does a Powerwall Cost?

All solar battery solutions are expensive, and you can expect to pay between $9,200 and $18,000 for a Tesla Powerwall, depending on the installation costs.

You can save by taking advantage of the federal solar tax credit when you buy solar batteries. This means you can deduct 30% of what you paid for your battery from your income tax in the same year.

Some states and utilities offer additional incentives when you install solar batteries. In California, you can save up to 90% on the cost of your Powerwall thanks to these incentives.

What Does the Tesla Powerwall Offer?

Some things to consider when you’re considering the best Powerwall battery for your home include energy capacity, power ratings, round-trip efficiency, and depth of discharge. The Tesla Powerwall won’t disappoint in any of these areas.

Energy Capacity

Tesla Powerwall capacity is 13.5 kWh, which is enough to output 3250 watts for four hours. The fewer watts you use from your Powerwall, the longer it will keep running.

Most appliances have a sticker attached to them that indicates the wattage they use, so you can easily manipulate your energy consumption.

Continuous Power Rating

Continuous power rating refers to how much electricity a battery can provide continuously while connected to a grid or solar system.

The Tesla Powerwall continuous power ratings vary from 5.8 kW for an on-grid installation with no sun to 9.6 kW for an off-grid installation with full sun.

You may need up to 14 solar panels to charge your Tesla Powerwall, depending on the solar hours available in your area.

Round Trip Efficiency and Depth of Discharge

Round trip efficiency refers to how efficiently a battery converts incoming energy into usable electricity.

The Powerwall has a 90% efficiency rating and a 100% depth of discharge. This means all the energy stored in the battery is available for use.
