When it comes to solar energy one of the greatest misconceptions is that by going solar you’ll never have to worry about losing power during an outage. In most cases, this isn’t true. Here’s why.
During a power outage, your solar panel system will automatically shut down. This is a safety precaution to protect utility repairmen as they work to restore power.
The good news is that there are ways around this. You could invest in a generator - either a small one to power just a couple major appliances or a hardwired large one meant to power your entire residence or office. Another option is to invest in a solar battery backup - specifically the Tesla Powerwall.
Why a Tesla Powerwall is Better
So, why would you invest in a Tesla Powerwall rather than a generator? Here are three good reasons:
- Solar battery backup compliments your commitment to going solar and generating your own electricity.
- The Tesla Powerwall can power your home for 7 days (or more!), but this also depends on a couple different factors: the site quality, how many panels are installed and how many batteries there are.
- There’s no manual effort on your part to keep your home up and running - it’s all automatic.
Now, let’s dig into each of these reasons.
1. Maintain Your Commitment to Going Solar
People choose to go solar for lots of reasons. They might be looking to lower their utility bills or they're passionate about helping the environment. Sometimes, it’s even just to “stick it to the man” and break away from the utility companies. And in many cases, it’s a little bit (or a lot) of a mix between the three.
Whichever reason has moved you to invest in solar energy, with a solar battery backup you can maintain that commitment. In the event of an outage, you’ll still be able to run your home or office on solar power for a week or more! Which brings us to our next point...
2. Seven Days Worth of Electricity
Even the most powerful generators on the market have limits. With a propane generator - the most environmentally-friendly of the bunch - that limit is the size of the propane tank and the number of them you have in reserve.
One tank of propane may be able to provide you with electricity for a day or more depending on how many appliances you have connected to it. However, if you’re hoping to keep your home running for a week or more, you’re going to need quite a few backup tanks at the ready.
With the Tesla Powerwall’s recommended installation (which is two batteries), your entire home or office will be powered for a week (or longer!). How? By using the solar energy that you’ve already generated and stored, which is prioritized over a tertiary power supply. And except for cases concerning the most extreme natural disasters, a week is plenty of time for the utility to have you back up and running again.
3. It’s All Automatic
Possibly one of the greatest benefits of the Tesla Powerwall is that the entire process is automatic. During a power outage, the grid automatically shuts down power to your home (and therefore cuts off your entire power supply - even your solar supply). When that happens, the Tesla Powerwall immediately kicks into gear so quickly that you may not even realize there’s an outage.
With other backup energy methods, there’s some level of manual work involved. For example, if you have a generator or a solar energy inverter, you’ll need to turn them both on and wait for them to kick in (just a minute or two) before your electricity comes back. If you’re using a generator, you’ve then got to keep the fuel tank full by refilling it or swapping it out. Every time you do this, you’re going to lose power during that process.
