Solar Power for Growing Cannabis

Pairing the power of the sun with life-sustaining cannabis is an outright good idea, as indoor growing operations require vast amounts of electricity to keep things going. Not to mention – with the advent of the legalization of cannabis – there are parallel rising concerns regarding the capacity of our power resources.

Beyond the amazing possibilities of using solar power for growing cannabis, the truth about the full context of the relationship between solar power and cannabis growing on a large scale can be cumbersome. With that said, this article intends to show that solar can absolutely help a cannabis operation reduce its electric bills and maximize profits – and it’s really not as complicated as it seems to be.

As national cannabis legalization is in the making, growth operations could transition outdoors since plants must no longer be hidden from view. When cannabis crops move outside or into mixed-light facilities, less electricity is needed to create an indoor ecosystem. With that said, indoor grow operations are still widespread, and any form of energy assistance such as the kind generated by solar comes as a huge relief to growers and the planet alike.

Benefits of Solar Power for Growing  Cannabis

It’s no secret that cannabis is extremely power-hungry, and therefore, one’s electric bill is easily the most substantial cost. During the vegetative stage, plants require intense light, as much as 18 hours a day. Fans constantly turn to avoid anything getting too hot. Not to mention dehumidifiers, along with a host of other elements that run around the clock to create an ideal growing space.

Going off-grid, for instance, used to hold appeal for illegal growers insomuch as they are no longer getting caught by astronomical energy bills. But as legalization escalates and the intention and legality of off-grid growing changes, the demand for marijuana skyrockets.

All of this, on par with the cost of energy and immense strain on our grid system, means growing with solar power entails benefits that simply can’t be ignored, such as:

  • Significantly decreased energy bills.
  • Everlasting protection from rising electricity rates.
  • Significantly reduced risk lost crops.
  • Lower carbon footprint – which is great for the planet.

If a grower cannot find a cost-efficient way to create the resources that cannabis plants need indoors, an alternative, cheaper way to produce the power is the definitive answer to more cost-efficient indoor farming.

Using a solar energy system or kit is the best way to generate electricity at a cheaper price. While utility prices for power increase each year, buying a solar energy system or kit places the majority of costs up front and fixed.

Using a kit to reduce electricity charges leads to farmers maximizing their savings.

More Reason to Ditch Non Solar Powered Grows

Although recreational and medicinal marijuana legalization has yet to reach federal status in the US, growers still rank among the most prodigious users of electricity.

When addressing the electricity usage of indoor cannabis growing facilities, both legal and illicit, it’s clear to see why going solar is not only wise, but inevitable.

According to a study by the Lawrence Berkeley National Laboratory, indoor cannabis operations are responsible for approximately 1 percent of the United States’ total energy use. This was at a time before a single state had legalized cannabis for recreational purposes. And, at the time, fewer than 20 states had legalized medicinal marijuana.

Large-scale, industrial-style cannabis cultivation for legal markets has only just begun to appear, yet the fledgling industry was already on the ranks of the country’s highest energy hogs. By growing indoors – openly or in secret – cannabis was consuming enough energy to meet the power needs of 1.7 million American homes!

Not surprisingly, these energy-eating practices are expected to worsen as legalization spreads, unless we instill an alternative, all-natural means of power resource such as that provided by solar power. It is forecasted that the demand for electricity from legal cannabis is set to increase by162 percent up to 2022. In the shadow of this reality, we can only turn to the sun for solutions.

A Brief History and Current Stance on Solar Power in the Cannabis Industry

In case we haven’t realized by now, solar and cannabis are and should be well acquainted with one another. Even some of the earliest prohibited cannabis growers used solar panels to offset its electric load so the government wouldn’t be able to pinpoint high utility bills. But the scale of legal cannabis grows today is a much bigger energy concern than a few hidden plants.

With the vast majority of grows being indoor by nature (since the product is more easily controlled in this manne it’s safe to assume the market is shifting to outdoor and greenhouse ops. But does that mean that indoor grows will be eliminated? Not at all – and by no means!

Let’s say the industry shifts to 50% indoor, 50% outdoor/greenhouse. Even then, the indoor segment is still going to be a big problem for utilities. Even if it’s 25% indoor, it will still be a big issue, hence we need the power of the sun more than ever! What obstacles are needed to overcome in order for us to turn words into action?

Obstacles to Overcome for Solar Energy to Rule

When it comes to harnessing the amazing possibilities of using solar power for growing cannabis, there are certain elements to overcome. While solar is totally possible and used by many in the legal cannabis industry today, there are still some obstacles and risks involved. Firstly, solar financing is an issue – and it goes without saying that the latest pandemic is not helping with that.

Looking at early recreational states, what’s remarkable is the level of DIY those people applied. Regarding legality, for example, Oregon capped the amount of space that indoor commercial growers are permitted to use – only 10,000 sq. ft. While some grow operations use every inch for growing fine cannabis, Oregon’s size restrictions probably leave some extra room for a few solar panels.

Understanding particular requirements can help you narrow the focus to grow with the best solar potential, in general.Solar is often included in the larger energy efficiency discussion within the cannabis industry, something many people don’t like to discuss. It is estimated that even with significant efficiency rebate programs from utilities, only a maximum of 2% of growers uses efficient manufacturing products such LED lighting.

In the light of this, solar should be at the top of your must-have upgrades. With all this being said, we are of the contention that sustainability is required and growers need to be educated about energy efficiency and the limitless potential of solar power for cannabis operations. Similar education is necessary regarding urban planning considerations.

Urban Planning Considerations

As legalization becomes more dominant, states reconsider their regulations on growing cannabis, meaning growers can move outdoors and into more traditional farm settings. In other legal states such as Colorado, Massachusetts and Washington, however, growers are actually required to grow their plants indoors.

As a result, many growers in the Rocky Mountain State are moving to greenhouses, moreover allowing growers to take advantage of nature’s gift of direct sunlight, as well as gain total control over their growing environment.

  • Plant Factories & Indoor Urban Farms

As urban farming becomes a necessity in densely populated areas, indoor agriculture is expanding. In areas where the cost of transporting food outweighs the cost of local production, plant factories and indoor urban farms are undoubtedly gaining popularity.

  • Space Considerations

We’re going to have to take a lot of Earth’s habitat into space with us. In order to provide sustainable sources of food and oxygen for astronauts, researchers are working with NASA to create lunar greenhouses that could be deployed in flight or even on other planets! But the total control that indoor agriculture offers also creates problems for indoor growers.

Without access to direct sunlight, electricity quickly becomes an issue. In particular, for closed spaces, one needs to regulate the surrounding temperature as well as the amount of light the plants receive. According to statistics, around 70% of the operational cost of an indoor farm is created by the cost of electrical energy alone – as also attested to throughout this article on the amazing possibilities of using solar power for growing cannabis.

Right now, the human race able to produce around ten grams of crop per kilowatt-hour of electricity – according to the experts. In order to make indoor agriculture a more widespread reality, the cost of energy resources needs to be dramatically reduced, which can, in turn, be achieved by more efficiently recreating the resources the plants need – or by using more efficient systems to produce the power, such as solar power.

America’s First Gigantic Solar-Powered Cannabis Grow as Inspiration

Feeling overwhelmed by the near-constant flood of dismal climate news? Well, here’s a breath of fresh air. Along with solar panels and other savvy efficiency mechanisms like water recycling and LED lighting, the microgrid has already enabled companies to cut their emissions in half. This is certainly a promising example for an industry that has largely failed to change in the face of escalating climate-related disasters.

Whatever you do, don’t hold off on going solar, since the legalization of more states only means that emissions are guaranteed to climb. One 2018 paper shows that the industry's energy demands could jump by 162% by 2022. And as this happens, the feds – drug policy and environmental policy must be harmonized.

Until then, some of the nation’s hard-earned progress towards climate change solutions is on the chopping block as regulators continue to ignore the cannabis industry’s mushrooming carbon footprint. It’s time to go solar!

Tips for Buying Your Solar Setup

  1. Multiple quotes means more savings

As with any investment-type purchase, buying the right solar panel installation should entail proper research and consideration. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory recommended that consumers are wise in comparing many solar options to avoid paying high prices offered by some installers in the solar industry.

To find contractors that typically offer lower prices, we recommend that you use an installer sun-power-oriented company like any of the ones we recommend in this article. Please refer to the section below in the form of a helpful buyer’s guide.

  1. The biggest installers don’t always have the best prices

We encourage homeowners to consider all of their solar options, as bigger isn’t always better. As a matter of fact, a report by the U.S. government found that large installers generally cost over $2,000 to $5,000 more than with small solar companies. In this article, we help you out by comparing all the best offerings from various of the best solar installers to ensure you don’t spend more than you should.

  1. Comparing all your equipment options

National-scale installers not only charge higher prices, but they also tend to have fewer solar equipment options. By collecting a diverse array of solar bids, you can compare your costs and savings based on the different equipment packages available to you. When seeking out the best solar panels on the market, there are multiple variables to consider.

While certain panels will have higher efficiency than others, simply buying the most expensive solar equipment doesn’t necessarily equal greater savings. This article on the amazing possibilities of using solar power for growing cannabis intends to help you find your sweet spot by evaluating varying equipment and financing offers.
