    Solar Power Off The Grid: Not As Tricky As You Think

    Setting up solar power off the grid is a scary thought for many people. The first question is usually what happens when the sun does not shine?

    Let’s dive into the basics of solar power and get an understanding of how it works

    Firstly.What Does Off The Grid Mean?

    Going off-the-grid does not mean that you must abandon society, and cut yourself off from all services, all technology and all people. Far from it.

    There are many different forms of living off the grid. It may mean that you gradually start to supply your own sources of energy, water and septic systems so you are not reliant on public and government utilities to provide them.

    Some people may choose somewhere in between where they supplement the city systems with their own energy or water.

    Some may choose to supply their own power, but retain access to city water.

    Others choose to be off the grid completely. All options work- it just depends on your skill level and desire.

    Reasons People Choose To Use Solar Power Off The Grid

    Most people will cite one of these reasons for wanting to generate and use solar energy:

    Great backup/self-reliance

    In the event of a simple power outage, you will have your own system ready to switch on. Is it possible that one day the grid goes down for an hour? A day? A week? How long would you last without power?

    The satisfaction of knowing you’ve got it all sorted- should their be some sort of event that cuts of city power is incredibly intoxicating.

    Save electricity costs ​

    Some people wish to off-set their electricity bills and not rely solely on the grid. Others generate a surplus of energy and can sell their energy back to the grid.

    Environmentally-Friendly

    Some people wish to help the environment by using a renewable source of energy and help eliminate their carbon footprint.

    jerky, solar, generator

    Tech/engineering interest

    Others love the technology and figuring out amps, voltage and wattage and wiring it altogether. There is a lot to learn and it can become a super addictive hobby.

    What Exactly Are Solar Panels?

    Solar panels also called as PVs (Photovoltaics) are devices that are utilized to convert light energy into electricity. Since the sun is a massive source of light, solar panels collect the light energy and convert it into DC power.

    Then, a solar inverter is used to transform the DC power into AC power which powers home appliances.

    Solar panels are used in many applications such as water pumping systems, remote homes, telecommunications, cabins, traffic warning lights, and more.

    This one is light, its portable, its less than 150. It delivers 100W and you can take it camping, hiking or power small appliances at home to start getting used to generating your own energy.

    Systems To Ensure Solar Power Off The Grid

    Hybrid

    The hybrid solar system is a modernized system that combines both solar and battery storage. This means that it is able to generate power just like the common on-grid solar does but integrates the use of batteries as an energy storage to power devices for later use.

    It is a highly-useful backup resource to supply power during electricity shortage or blackout.

    Solar Power Off The Grid

    Off-grid systems generate their own power without relying on the municipal grid at all. Your system also needs to be able to generate and store power during the winter and across several rainy days or overcast days.

    There are many different ways to configure the system depending on your needs.

    How much energy does your household use per day now?

    If you are currently living with traditional grid power, it is likely you never think about how much energy a light bulb or your air conditioner uses.

    You likely never think about whether you should use the vacuum cleaner at the same time as the washing machine at the same time as your son is using the power tools and your daughter is in the shower.

    Once you switch to solar power off the grid, it is essential that you are aware of how much energy you are using at all times simultaneously and across a whole day. If you use too much energy at the one time, your inverter will shut down.

    In this video, Jaime estimates that when they were living on grid, they used 60kwh per day. Now they use 4-6Kwh, perhaps up to 10kwH day in the heat of summer with the air conditioner.

    Check it out- it has some useful insights:

    There will be a time of year when there is minimal sunlight so you must carefully plan what battery capacity is needed to meet your household’s requirements.

    It is important to monitor how much energy you are consuming during the day so you do not run out.

    Also be careful to not overload the system- even when the sun is shining.

    What Are The Components Of A Solar Power Off The Grid System?

    Solar (PV) Panels Solar cells convert sunlight to electricity through a photovoltaic effect, capturing sunlight’s photon, and absorbing the radiation to generate power and transmit them to the batteries.

    Battery Bank. The batteries will store the energy collected from the sun and will disperse energy when you need it including at night time and on cloudy days.

    Charge Controller This helps the batteries to produce the most efficient performance and that they are not overcharged.

    DC-AC Load Center This is a panel board with corresponding fuses, switches, and circuit breakers to ensure the appropriate voltage and current is maintained.

    DC-AC Inverter This converts DC into AC to power your household appliances.

    Backup Generator This is not essential but is a useful back-up if your battery banks run out of power.

    How Much Power Do You Need Per Day?

    First, you need to determine the appliances you are going to use and for what length of time, you will use them. Calculate the daily load you will be needing.

    To calculate accurately, you can do simple math by following the guidelines below:

    Identify the appliances you want to operate and list down the hours you will be likely to run them.

    They may be more than you think-TVs, computers, dishwashers, washing machines, hair straighteners, phone chargers, fridge, internet router, electric razros etc etc

    Your appliances should have the specs on the back. Look for it and see the power rating.

    Calculate the watt-hours by adding the power rating and the run time (number of hours). For example, you want to run a 12W fluorescent lamp for about 4 hours from your off-grid solar panel, the calculation is equal to:

    Power rating: 12W

    Run time: 4hrs

    Watt Hour = 48Whrs

    Repeat this process for all your appliances and sum them up together.

    Light = 12W x 4hrs = 48Whrs

    Total Watt Hours: 363Whrs

    A tool like the Kill a Watt electric monitor will also measure this and start to get you clued in to your energy usage and how you can save a ton of money off your electric bill.

    Even if you decide to not live off the grid, this tool will save you far more off your electric bill than the 18 this tool costs.

    Start your solar power off the grid journey by checking in with this meter and seeing if you can start to reduce your energy usage simply by being more aware. Just plug it in and you will quickly see where you are wasting a ton of energy (and cash!)

    Also work how much energy you will need at one time. This will determine which inverter you need.

    Do you need the washing machine, computers power tools, air conditioning all on at the same time or are you prepared to spread them out over the day?

    The inverter’s job is to convert DC power from batteries to AC power for the appliances. 1000W inverter means you can run 1000W at the same time.

    Eg if your fridge uses 80W/hour, coffee pot 800W/hour, LED bulbs 28W/hour, this is approx 900W. You know that you would not want to switch on your washing machine right then until you turned one of these off (or bought a higher capacity inverter).

    Renogy is a very good brand in this space. You can pick up the Renogy 1000W inverter ​for less than 200

    How Many Batteries Do You Need For Your Solar Power Off- The-Grid Life?

    Budget is a major factor in choosing battery requirements.

    Plus how much sunshine you get where you live.

    If you live in a place that has guaranteed sunshine for 4-9 hours per day most of the year, you can get away with less battery storage.

    However if you know that you cannot rely on the weather, you need to have enough battery storage for 3-4 days at least. Solar power will still be generated on cloudy days just not as much as sunny days.

    Typically, the bigger your solar system, the higher voltage battery banks you will need to keep. If you generate 1000W energy per day but your batteries are full at 500W, then you are just wasting the extra 500W as it has nowhere to go and get stored.

    It’s best to go to your local store to pick up batteries as they are expensive to ship and can be hazardous.

    It is best to use golf cart batteries rather than car batteries, as they last longer and are quicker to charge up.

    Also it is best not to let the batteries run to below 50% of their storage capacity as it lessens their lifespan.

    How Many Solar Panels Do You Need For Your Solar Power Off- The-Grid Life?

    You know from your homework earlier how many KwHours you need to run your household per day.

    Consider the location and the time of year when calculating the number. Observe how many hours the sun shines in your area throughout the day so that you will not have a power shortage especially in the winter.

    If you are looking to buy a reliable solar panel, then check out these products:

    Smaller and good starter model:

    Eco-Worthy 20W 12V Solar Panel Kit ​

    This item is affordable yet delivers high energy conversion at the lowest standby current.

    It’s a budget-friendly product that is suitable for hobbyists and students, allowing you to carry it for outdoor and camping activities.

    It can power up one or two of your gadgets at a time.

    It can withstand snow loads and high winds.

    If you want a solar panel to run your DC devices such as fan, LED light, and even a linear actuator for a chicken coop.

    Another one in our top picks is the Renogy 100W 12V Monocrystalline Solar Panel.

    Renogy are one of the best- you can call them and they can help you out with your requirements. This is more robust for a decent size household.

    This company has many products in the off grid living space. This is a popular product great for powering a home or even take it on a camping trip to power your site.

    Whether you want to charge your 12V battery or opt to wire up multiple panels in series for 24V/48V battery, the Renogy does its impressive work.

    It’s weather-resistant, compatible for both on-grid and off-grid inverters and is highly-efficient, providing an ideal output of 500W a day depending on the availability of sunlight.

    But What If The Sun Don’t Shine?

    A big factor of course is where you live and how many sun hours you get per day and across the seasons.

    If you have the 1000W inverter, this is 1kwH per day.

    If sun shines 4 hours a day, and you have 4 x 300W panels, then you will generate 1200W a day.

    If you live somewhere where you get 8-9 hrs a day, even better.

    If you live in Nevada you might only need one panel and be able to generate 300W x 9hrs=2700W

    Its always a good idea to have an extra panel or two to stock up for cloudy days or unexpected weather.

    Solar Power Off The Grid Safety

    Though many consider it boring to talk about safety, when dealing with electricity, it is vital to ensure your system is safe and fit for purpose.

    Unless you are an electrician or have skills in that area, be sure to fully understand what you are doing or have a solar company do most of the installation for you.

    If you choose to do it yourself, be sure to have a qualified electrician give it the final check over to make sure you, your family and any visitors, neighbors or passers by are safe.

    An electrician might be aware of things you had not thought of:

    What if your batteries get wet?

    What if there is a lightning storm?

    What if there is a sudden surge of electricity- will it damage all your appliances? will it cause a fire?

    What if there is a short circuit?

    Always take electricity seriously.

    Solar Power Off The Grid Summary

    Remember humans have lived without electricity for nearly their entire existence. It is a relatively recent phenomenon which we now take for granted. Most of us waste a lot of energy without realizing it.

    Using solar power can make you more appreciative of energy. First assess what you use currently. Then see if you can reduce this usage.

    Perhaps start small and power your hairdryer or the chicken coop and understand the basics.

    Later you can add solar panels, inverters and battery storage to your home. Even though there is an upfront investment, it will pay for itself over time.

    And if the technicalities are too much to get to grips with, you can have a professional company come out and do the install for you.

    Habitability and the Evolution of Life Under Our Magnetic Shield

    A Robust Proxy for Geomagnetic Reversal Rates in Deep Time

    Most people don’t know that Earth’s magnetic field has a weak spot the size of the continental United States hovering over South America and the southern Atlantic Ocean.

    We’re safe from any effects on the ground, but our satellites aren’t so lucky: When they zip through this magnetic anomaly, they are bombarded with radiation more intense than anywhere else in orbit. There is reason to believe that this dent in the magnetic field, called the South Atlantic Anomaly, is only getting bigger.

    This anomaly is far from the only unusual feature of Earth’s magnetic field.

    Hundreds of times in Earth’s history, our magnetic field has reversed, switching north and south in a planetary flip-flop. Earth’s magnetic North Pole keeps drifting too, stumbling around the Arctic in a chaotic dance. And scientists have detected pulses of Earth’s magnetic field—called geomagnetic jerks—that can undermine our navigation systems.

    Yet forecasting these changes remains a challenge. “Just like weather forecasts, you can’t predict the evolution of the core beyond a few decades,” said Julien Aubert, a researcher at the Paris Institute of Earth Physics.

    But scientists want to know how Earth’s magnetic field will change further into the future than that. Without a magnetic field, satellites could be lost, and tools that rely on careful magnetic models for navigation could go askew.

    The answers can’t come soon enough. The magnetic field protects Earth’s atmosphere from harmful radiation emitted from the Sun. Scientists are learning that the Sun is capable of emission events—solar flares—even more destructive than we ever thought possible, and understanding our magnetic field strength and variation is vital for knowing how at risk we could be from the next big solar storm.

    The Iron Heart

    The puppeteer that drives the magnetic field is Earth’s core, the superheated heart of our planet, which burns as hot as the surface of the Sun.

    In the core, molten metals are constantly in motion as hot buoyant plumes of lighter material rise outward. At the very center lies a small hardened inner core that has been growing as Earth cools.

    On an early spring day in 2016, teams of engineers in Japan watched as their prized satellite spun out of control.

    The teams behind Hitomi, a satellite launched just 5 weeks earlier, had hoped the spacecraft would observe black holes, Galaxy clusters, and other high-energy features. The satellite even had a prized X-ray calorimeter, a triumph of 3 decades of engineering.

    jerky, solar, generator

    But a cascade of events that began with encountering the South Atlantic Anomaly seemed to spell doom for Hitomi. Passing through the anomaly, the onboard system that controlled the satellite’s orientation glitched while it was pivoting to observe a new star cluster. The maneuver kicked off a series of software errors that left Hitomi spinning madly. Before long, the satellite broke into 11 pieces.

    “It’s a scientific tragedy,” Richard Mushotzky, an astronomer at the University of Maryland in College Park, told Nature at the time.

    Other spacecraft have fallen prey to the South Atlantic Anomaly. The magnetic field intensity at the altitude of many satellites is half as strong in the anomaly compared with elsewhere, and the weak field does not repel radiation as effectively. The inner Van Allen radiation belt, a doughnut-shaped disk of radiation around Earth that traps high-energy particles, hugs much closer to the surface at the anomaly because of the weakened field.

    Any satellite in near-Earth orbit—a common altitude for Earth observing satellites—must travel through the anomaly. The Hubble Space Telescope spends 15% of its life in the region—and routinely shuts down its light-sensitive cameras to avoid damage. Some instruments, like NASA’s Ionospheric Connection Explorer, power down electrical components of an ultraviolet photon detector every time they pass through. In the early days of the International Space Station, the anomaly would crash astronauts’ computers.

    But sometimes a satellite is just unlucky. Ashley Greeley, a postdoctoral scholar at NASA Goddard Space Flight Center, recalled a CubeSat that died shortly after launch. During start-up checks and the commissioning phase, “we think that an energetic particle hit it in the wrong place at the wrong time, and we never got data, unfortunately,” she said.

    A Growing Anomaly

    Researchers discovered the South Atlantic Anomaly in 1958 when satellites first began measuring radiation in space. Now the region shows up prominently in most models, said NASA’s Terence Sabaka. “Everybody is pretty much in agreement on its size, shape, and strength.” Although it’s still a matter of speculation, there is some evidence that the anomaly has been around since the very early 19th century and maybe even earlier.

    The real debate surrounds what the anomaly will do next.

    Although the dent is projected to grow in the next 5 years, it’s impossible to make predictions further into the future, said Kuang. Fluid movement in Earth’s core is so turbulent that a small perturbation to the system could lead to a cascade of outcomes that we can’t foresee. The further you go in time, the more runaway situations abound.

    Although the future is uncertain, studying the anomaly “provides a very good window for us to understand not only the core dynamics,” said Kuang, but also “the regional properties of this area.”

    Luckily, the anomaly can’t hurt life on the surface, said Kuang. “But if it continues to weaken over time, this may eventually impact us.” The hole in our field would expose us to high-energy particles that could surge power grids and eat away at protective gases in our atmosphere.

    Magnetic Shudders and a Wandering Pole

    Chengli Huang’s daughter would often hear a familiar story at bedtime.

    One day, four blind men decided to go to the zoo to visit an elephant. They’d never met one before, and they wanted to know what it looked like. The first man approached the elephant, felt its trunk, and declared it a “curved paddle.” The second touched its tail and concluded it was like a stick. The third man gingerly patted the body and pronounced that the animal looked like a wall, whereas the fourth felt its leg and said it was like a pillar.

    Separately, the four men understood only one part of the elephant. But together, they had a clearer picture of the elephant’s true nature.

    Scientists also call the jerks “V-shaped” events based on their appearance in plots of the field’s rate of change over time. The events usually last between 1 and 3 years, and the first documented case was recorded in 1902. Dozens of jerks have happened since.

    The last jerk was in 2016, when it jostled the field and dramatically shifted the North Pole drift. The event was rather inconvenient because scientists had just issued a 5- year model of Earth’s magnetic field called the World Magnetic Model (WMM). The WMM team had to update the model ahead of schedule to avoid unacceptable navigational errors.

    Although the origin of jerks is a subject of active research, a recent study in Nature Geoscience by Aubert and Chris Finlay at the Technical University of Denmark suggests that jerks may originate from the push and pull of forces in Earth’s interior (bit.ly/jerks-research). When a hot plume shoots up through the outer core, the delicate balance between planetary, rotational, and electromagnetic forces careens out of whack. The off-balance forces send a shudder along magnetic field lines in the form of waves.

    The next jerk may already be under way. A recent analysis by Huang and Duan predicted that the next event would occur in 2020 or 2021.

    If that’s the case, scientists may need to update magnetic maps on which industry and government activities rely. Companies drilling for oil and gas, for example, use fine-tuned magnetic models to dig boreholes. But not all jerks cause directional changes, so time will tell what the outcome will be.

    In one grim scenario, a catastrophically massive solar flare envelops Earth and knocks out the ozone layer, exposing us to damaging ultraviolet radiation known to cause cancer. In the 6–12 months it would take to rebuild our ozone layer, we’d live like “nocturnal animals,” Airapetian said.

    “You’d have to go underground and go out during the nighttime,” said Airapetian, a NASA scientist at the Goddard Space Flight Center. “That’s the Hollywood-type scenario.”

    jerky, solar, generator

    Tales of our field catastrophically failing are part of the lore of working on Earth’s magnetic field. People always want to know, “When is the really, really bad stuff happening?” said Aubert.

    Although the prevailing science suggests that these doomsday scenarios are possible, they are highly unlikely. Earth’s magnetic field is fickle, cratered, and ever changing, but scientists have no reason to believe that the field won’t protect us for decades—and most likely centuries—to come.

    Even one of the most dramatic of the scenarios, a magnetic reversal, is implausible in the foreseeable future. The last reversal occurred 780,000 years ago, and over the multibillion-year lifetime of the magnetic field, researchers guess that the poles have switched hundreds of times.
