What The Tesla Battery Could Mean For Growers

Tesla has announced the creation of a battery that can power a house, and it is going to revolutionise the way we grow weed.

Growing cannabis indoors can be an expensive endeavour, especially for the legal marijuana industry. When you start blaring out the light with multiple 1000 watt HPS lights, it is not unheard of an electricity bill to reach over €1000 a month!

Fortunately, advances in renewable power may hold the key to reducing this cost for commercial operations, and completely eliminate it for the hobbyist grower only cultivating a couple of plants. This advance comes from Tesla, the high end electric car company that have made it their long term goal to revolutionise the energy market – and they are making leaps and bounds at achieving it. The latest innovation is Powerwall - a battery for your house or business that is able to connect to solar panels, storing the energy so it is available when you need it.


This may not sound all that innovative - but it is. Until now, if you have solar panels or a wind turbine, the energy has to be used as it is generated, or it is lost. As a result, most people that have solar panels use a little of what is generated, with the rest being pumped into the national electricity grid. With this battery, you will be able to store up this energy and us it to power your house – including your grow lights.

The first generation of Tesla batteries are going to be able to store 10KWh, and will be stackable. The average household uses around 11-12KWh per day, and couple of medium powered lights (or even better, power conserving LEDs) aren’t going to add much onto this. This means that in theory, if you live somewhere with a lot of sun, you could power your entire house and grow from these batteries.

The advantages of this are many. Firstly, it is green renewable energy. Secondly, it all but eliminates expensive power bills. And last but not least, if you power your house and grow from the batteries, the energy companies can’t effectively monitor your use or potentially rat you out to the police.

The battery can also link up to mains electricity. So if you do not have solar panels, you can always charge it up from the mains. Whilst this isn’t going to save you energy or disguise usage, it will be a handy backup power source should you encounter a blackout.


Each battery is going to have a base cost of $3500 (roughly €3150), not including installation fees. Then there is the fact that installing solar panels is not cheap either. As such, it could take up to 10 years of reduced energy bills to breakeven on the initial cost. However, if you intend to stay in your house for the long-term future it could be a worthwhile investment.

Then there is the fact that 10KWh may not be very practical for the burgeoning and energy hungry marijuana industry. Yes the batteries can be stacked almost infinitely, but it may not be cost efficient to do so.

Fortunately, this ground breaking technology is unlikely to halt here. Just think about it, if you go back 30 years or so and computers were the size of a room. Now they can fit in our pocket. Now that this technology has been developed, it will definitely continue to advance. And when you consider that the minds at Tesla are some of the smartest on the globe, it probably won’t take them very long!
