Tesla Powerwall vs. Traditional Solar Panels: What You Need to Know

Posted by Colin Gload on Sep 30, 2019 11:39:58 AM

When it comes to solar energy, it’s not as simple as just choosing to make the switch. You’ll also have to understand the various types of equipment available. The transition may seem daunting at first, but with just a little bit of information, you can easily get an idea of what technology will best suit your needs.

Tesla Powerwall and Traditional Solar Panels

At Lumina Solar, we offer two main types of solar technology: solar-powered battery equipment, like the Tesla Powerwall, and the standard grid-connected panels that are commonly seen throughout Baltimore neighborhoods. 

In this post, we’ll fill you in on the key differences between the two types of gear that we offer to give you a better understanding of how it all works. 

Traditional Solar Panels 

When people first hear about solar energy, they often assume that moving forward with it means that they will be going “off the grid.” Although off-grid systems have many advantages, staying connected isn't necessarily a bad thing. You don’t have to go off the grid to make a difference. The more people use grid-connected solar energy, the less energy there will be derived from unethical sources flowing through the power lines. 

If you produce excess energy with traditional solar panels, it’s dispersed through the utility grid to other homes. When that happens, you’ll also receive a credit for it on your utility bill. While most of the time you’ll owe nothing to the utility company, there are likely to be some months where you slightly under produce. The credits that you accumulate during the months that you overproduce energy offset those costs and work to keep your utility bill free. 

Grid-tied solar panels take advantage of the pre-existing structures in place to store and move energy. If you have access to power lines and are looking to supply energy to a permanent structure, grid-connected panels are the right place to start and will supply you with a solid foundation for continuing your commitment to renewable energy by adding in devices like the Tesla Powerwall.

Tesla Powerwall 

The Tesla Powerwall is different from other solar technology in a few key ways. 

For starters, it’s meant to be used alongside other forms of solar technology, and not as a standalone system. And instead of supplying energy to the utility grid for storage, this unit operates by storing solar energy inside of a battery. For that reason, when there’s an outage in the utility grid, the Tesla Powerwall will step up to handle your electricity needs.

When installed as recommended, the Tesla Powerwall has the capacity to power an entire home for up to a week. 

It can be used in just about any circumstances that a generator would be used. However, it has advantages that makes it the clear winner over other types of backup power units. 

Most generators only have the potential to power a home for about a day or so before the propane tank needs to be changed out. The Tesla Powerwall lasts much longer while simultaneously utilizing green energy. 

The Tesla Powerwall can also be used to supplement the energy generated by your solar panels during “peak” times throughout the day. Many utility companies charge a variable rate which often means paying more for energy during high use hours. The time-based control technology featured in the Tesla Powerwall can sense these patterns, and in turn, disperse its stored energy to offset utility dependent energy usage during those times. 

With that information in mind, it’s clear to see how this unit can take your use of renewable energy to the next level.
