Tesla Powerwall Stacking Kits are becoming quite popular among those looking for a supplemental source of energy. Depending on your needs and goals, a Powerwall Stacking kit may be a wise investment for your home.
Tesla Powerwalls are large battery banks that store energy for use when the grid goes down. Each Powerwall can store 13.5kWh. Powerwalls can be used in single units or you can stack up to 10 Powerwalls together for form a 135kWh battery bank.
Tesla Powerwall is a viable supplement to conventional energy sources. Although the up-front cost may seem exorbitant, in the long run these batteries can save you more than they cost you. We’ll discuss the advantages and drawbacks of the Tesla Powerwall Stacking Kit.
Tesla Powerwall Is An Alternate Energy Source
Tesla Powerwall panels are large 13.5kW lithium-ion batteries that store energy either from the grid or from solar rays. These panels detect power outages and automatically begin powering the load that has been assigned to them.
Powerwalls may be assigned to power the whole house or just a portion of it.
Since each panel discharges only five kilowatts of power, you will need more than one panel to power even a portion of your house.
For this reason, Tesla has made their Powerwall panels stackable. This means that multiple panels can be placed together, either side by side or front to back.
If placed side by side, space must be left between them for electrical connections and sufficient air circulation to keep the panels cooled.
If stacked front to back, you can stack no more than three. However, you can incorporate three stacks of three panels each in your house, depending on your electrical configuration.
They are joined with special clips and attached to the wall.
Single Powerwall panels may be wall-mounted, but stacked panels are too heavy for that. They must have a solid support underneath them.
Powerwall units may be:
- Built into a wall
- Placed in a garage
- Placed outside
- Installed in a basement
Since there are no fumes or exhaust, they can be placed literally anywhere in the house. Just be sure that they are safe from areas that are prone to flood.
If placed outside, be careful to keep them free from leaves and debris. Powerwalls should not be placed in direct sunlight or continuously exposed to extreme temperatures.
Do I Need Tesla If I Have Solar?
Yes. While your solar panels produce energy, they do not store energy. Solar panels generate more energy than most households use in daylight hours.
So, all the unused energy is wasted when the sun goes down. Even if you sell it back to your energy company, you have to pay them to use your own solar-generated energy at night.
With Tesla Powerwall, all that excess energy gets stored for use at a later time.
If your house is solar powered completely, Powerwalls may be set to power the house at night or on cloudy days when the sun’s rays do not reach Earth in their full strength.
Powerwall is designed to work with your existing solar panels, or it can be integrated into a new solar panel installation.
The Reasons For Using Powerwall Are Compelling
Why should you consider installing Powerwall? A variety of reasons come to mind.
- Lowering energy costs
- Renewable energy source
- Alternate power source during blackouts
Any one of these reasons is viable enough to justify the investment in a Tesla Powerwall.
Reduce Energy Bills With Powerwall
Maybe you don’t want to go off-grid completely, but you would like to supplement your current electrical supply with something more cost-efficient.
Enter Tesla Powerwall. Powerwall can assist you in lowering your energy expenses by using stored energy during peak hours and high-cost seasons.
If you live in an area where temperatures are mild for much of the year, you could use Powerwall for all but the most extreme months when air conditioning or heating would be necessary.
This would help to lower your energy costs significantly.
Save The Environment With Powerwall
If you want to do your part in reducing carbon emissions, Powerwall is an excellent source of clean, renewable energy.
The more natural energy you use, the fewer fossil fuels must be burned to create energy. This will help to improve our environment and clean up the air we breathe.
The sun will continue to burn for at least the rest of our lifetime, so pairing solar energy with Powerwall storage capacity means you will always have all the clean energy you could ever need.
Fear Blackouts No More When You Have Powerwall
Blackouts are a given in many areas for several reasons. Some blackouts are intentional to reduce the load on the grid during times of high demand.
Other reasons for blackouts may include:
- Downed trees
- Blown transformers
- Damaged lines
None of these circumstances need to bother you when you have Powerwall.
If you live in an area prone to hurricanes or tornadoes, Powerwall can keep you powered during disasters.
Powerwall can even communicate with the National Weather Service to prepare for a predicted storm. In these times, Powerwall may increase its charging rate to be sure that it is fully charged before the storm arrives.
Why Use Powerwall Instead Of A Generator?
Many people in hurricane-prone areas keep generators as an alternate power source when the grid goes down.
Generators can run an entire household or power the most important elements just like Powerwall can and they cost much less. So why choose a Powerwall that costs thousands over a $400 generator?
Generators Are Finicky
Generators require almost constant tending. You must see that they have sufficient gas and oil in them to keep them running.
They are notoriously unreliable when it comes to getting them started. Let them sit for a few months, and they obstinately refuse to crank.
They produce lots of noise and harmful fumes. Generators cannot be used inside because of the carbon monoxide they put off through their exhaust.
Powerwall Is Self-Contained
By contrast, Tesla Powerwall:
- Make no noise
- Give off no fumes
- Need no ongoing maintenance
- Can be used inside
- Are fully reliable
This makes Tesla Powerwall a no-brainer for the homeowner who wants consistent performance from his back-up energy plan.
What is Tesla Powerwall’s Lifespan?
All rechargeable batteries lose their ability to hold a charge over time and Powerwall is no exception. However, they do retain their charging capacity longer than most.
Powerwall is guaranteed by Tesla to retain at least 70% of its charge capacity for ten years. That is when the warranty runs out, and after that, you’re on your own.
This applies only if you are using the battery every day. Tesla recommends that the battery should not be left unused for more than one month.
Can You Go Off-Grid With Powerwall?
It is possible, but obscenely expensive. One Powerwall fully charged will last about twelve hours, and that doesn’t include pulling any large appliances.
So, to power your entire home with solar and Powerwall would require so many panels, no one in the working middle class would be able to afford it.
As well, performance would be volatile at best because the charge your battery gets from your solar panels is affected by weather conditions which may remain unfavorable for days at a time.
Powerwall seems to work best as a supplement to your current energy source rather than acting as an alternate energy source. Maybe this will change in the near future as technology improves.
