Avoiding Power Outages
Having an off-grid solar system is like having your particular power supply that never takes a break. It’s way better than relying on regular city power, which can easily get messed up by bad weather, heavy rainstorms, strong winds, and freezing rain.
Power outages are obstacles to productivity and create uncomfortable living conditions. While short interruptions can be a minor annoyance, prolonged outages lasting for days or weeks can significantly impact daily life. Without lighting and essential appliances, everyday tasks become inconvenient, and waiting for the power to return is frustrating.
By installing an off-grid solar system in your home, you achieve self-sufficiency in energy generation. The solar panels harness sunlight and store excess energy in batteries, providing a reliable power source unaffected by storms, rain, wind, cold snaps, or heat waves. The standalone nature of off-grid equipment means you only need to consider your power requirements, ensuring a continuous power supply without concerns of outages.
Reduced Electricity Cost
Even today, fossil fuels like petroleum, coal, natural gas, and oil are the primary energy sources. However, these resources are finite and are depleting at a high rate. With this depletion, the prices for these resources continue to rise, and as a result, electricity bills are increasing daily.
It is also one of the benefits of off-grid solar power systems. While there is a one-time investment that you have to make when purchasing off-grid solar panels with batteries, you can save a lot in the long term. As the off-grid solar system relies solely on the sun to produce energy for the household, you no longer have to worry about the monthly electricity charges. An off-grid solar system is the best way to reduce electricity consumption at home and in commercial places and store energy in the batteries.
Easy Installation
The equipment associated with off-grid solar systems is not dependent on the grid; the installation process is much more straightforward than having to rely on complex infrastructure to function.
For instance, the installation of grid-tied systems requires the services of professionals to connect them to the city’s electric grid.
On the other hand, installing an off-grid solar system requires a homeowner to know standard tools. The process is more straightforward, which could eliminate the need to hire a professional.
Also taken out of the equation is the costly trenching process to put the collected solar energy on the grid, which is necessary for grid-tied systems.
Keep The Environment Green & Clean
As with any renewable energy source, solar power is more green and clean for the environment than fossil fuel energy.
Using off-grid or on-grid solar systems will still be more environmentally friendly than fossil fuel power.
Renewable energy lets everyone generate electricity without burning fossil fuels, reducing the carbon footprint produced by power.
Going off the grid is beneficial to nature as it minimizes the harmful effects of electricity on the environment by not being dependent on burning fossil fuels that pollute the air.
What Is Off Grid Solar System
An off-grid solar system pulls energy from the sun and its rays through solar panels, which most often are mounted to the roof of a home, cabin or RV. The energy the panels collect is then routed to a battery that stores the energy until you need it, when an inverter converts it into electricity.
What to Consider When Buying the Best Off-grid Solar System
Solar panels may look the same or slightly different to inexperienced people, but they are not the same. They come in the following types:
Monocrystalline solar panels
These are the most popular solar panels. You will know them by their black color. In addition, they are more efficient than other solar panels, for instance, polycrystalline ones.
The solar cells are made from a single silicon crystal, hence the name “mono.”
Polycrystalline solar panels
You will be able to tell the polycrystalline off grid solars from the monocrystalline ones by their blue color. However, these solar panels are made from many crystals of silicon, hence the name polycrystalline.
While polycrystalline solar panels have a lower efficiency as compared to monocrystalline ones, they are cheaper. Besides, the difference is not that much. For instance, they have an efficiency rate of 17 to 19% while monocrystalline ones have 18 to 23.5%.
Amorphous Solar Panels
These are thin-film panels. Although they are large, like some monocrystalline solar panels, they perform very well in direct sunlight.
Your solar panels will give you DC power. However, your home appliances use AC power. Therefore, you will need this inverter to convert the DC power to AC power.
Of course, most of the off grid solar panel systems come with inverters and if they do not, you will need to buy one separately. On that note, there are different types of inverters.
Some are huge, some are string types and yet others are micro in size. However, if the solar system does not come with one, you can always check with the solar panel manufacturer about the best inverter to buy.
This is another very important component of the off grid power systems using solar energy.
If you live in a sunny area or you have a high capacity solar panel that harnesses a lot of energy, you need a solar charge controller. You need this gadget irrespective of your solar system size.
This device controls the amount of current and voltage that is going to your battery. In addition, when the battery is full, the charge controller will not allow more current to pass. However, as soon as the battery is dispensed a bit, the charger controller will know that and allow the solar to continue charging.
To tell you the truth, going completely off-grid with solar is not going to be cheap. Therefore, you may need more solar panels compared to a person who wants an on-grid solar system, depending on your energy requirements.
Since you will need more solar panels, you will need a higher budget. In addition, you will also need solar panels with higher output and this can cost more. If you add the other components such as inverters and batteries, you can see just how much the budget will hike.
Depending on the size of your home, you could need small or big solar panels. For instance, if you have decided to reduce your carbon emissions by living in a tiny home, even a 200-Watt or 300-Watt solar panel, one deep cycle battery and charger controller can be enough.
To come up with a proper budget, you need to find out how much power you will need. This includes determining how much power your appliances and lighting fixtures consume.
To give you a proper estimate, you can expect to spend at least $500 for a complete 200-Watt off grid solar system for your small home.
You could install your off-grid solar system on your own and save the installation costs. However, it is better to hire a technician to install it for you.
In addition, you might also need to buy extra hardware from the store. For example, if you want to install the solar system in the backyard, you might need a mounting rack.
If you are going to install the solar panel on the roof, you might need extra installation hardware. Of course, most suppliers add the installation hardware such as screws, lead wires and others. However, in some cases, you will find that the screws are of lower quality.
The initial cost of buying and installing complete off grid solar kits with batteries is costly. However, after that, you can have a free run (literally) until you need to replace the off grid batteries.
Tips For Success: Living With An Off-Grid Solar Setup
In most grid-tied homes, occupants fire up appliances whenever it’s convenient. Off-grid clients need to understand that this isn’t the case with an off-grid solar system unless they install a very robust one. Because off-grid living often requires shifting the way they consume power, it is essential to make sure your clients are well informed.
Understand Electricity Loads
When sizing an off-grid solar system for the proposal, installers typically have clients list their power loads. Keep in mind that some power loads, such as the heating system, are seasonal. Now is also an excellent time to examine energy efficiency. Does your client have any really inefficient appliances that consume more power than needed? Do they have any loads running that don’t benefit them, such as an empty supplemental refrigerator or freezer?
It is also helpful to understand instantaneous loads so the inverter is adequately sized. Spreading out loads is beneficial to avoid overloading the solar system. For example, if the homeowner runs the microwave, there might not be enough amperage from their off-grid solar system for the water pump, power tools, and dishwasher.
Determine The Necessary Voltage For The Off-Grid Solar System
When deciding between a 12- and 24-volt solar energy system, there are pros and cons to either. Regardless, it is crucial to match the voltage of the battery bank and the inverter. A 12-volt solar system is ideal for small projects like RVs and tiny cabins.
A 24-volt system is usually ideal and has some benefits for homes that use 1,000 to 5,000 watts daily. These systems are more economical due to lower wiring and charge controller costs. Typically, installers series connect the batteries in a 24-volt system, which has durability advantages. There is also less wire loss at a higher voltage.
Consider the Batteries for the Off-grid Solar System
Adequate solar battery storage is vital for comfortable off-grid living. Because solar energy is intermittent and not always available, batteries must provide power when the sun isn’t shining.
Keep in mind that the federal tax credit does apply to off-grid systems and includes the battery cost. Thus, a more expensive battery will have a larger tax credit.
Common off-grid solar battery types:
● Lithium solar batteries have the longest lifespan and often come with a 10-year manufacturer’s warranty. Solar customers also like this option because they are safe and require no maintenance.
● Lead-acid batteries have a shorter lifespan and require some maintenance. The upside is that they have a lower upfront cost and are easy to recycle.
● Sealed AGM batteries have a shorter lifespan than lithium batteries, but they don’t require regular maintenance like lead-acid batteries.
If solar permits are necessary for off-grid PV installations in your area, then it is crucial to contact the authority having jurisdiction (AHJ). The solar permitting process and requirements vary widely between towns, so it's critical to know the process in the given jurisdiction.
Some building departments have online platforms for solar permit applications, while others require paperwork. The permitting fees for solar systems also vary widely and are designed to fund the permitting and inspection process.
In some areas, merely listing the solar panels, inverter, racking system, charge controller, solar batteries, and project cost might be enough for the off-grid solar permitting application. In other towns, town officials may require solar installation line diagrams and equipment spec sheets.
Do You Need A Permit For Off-Grid Solar System?
The permitting requirements for off-grid solar vary widely. If your client lives in a rural area, there might not be any permitting requirements. This is good news because it saves installers time, money, and hassle.
If you are installing an off-grid solar system in a city, there will likely be permitting requirements. When in doubt, determine if the town or municipality requires solar permits for off-grid PV systems. If a building permit is needed, the city will likely require an inspection after installing the solar PV system to ensure that the system meets electrical and building codes.
Although most code requirements on electrical and building codes are standard, some details can vary depending on local requirements. Because off-grid solar power systems are not connected to the power grid, no utility interconnection permit is needed from the utility company. Also, the system doesn’t qualify for net metering because it isn’t connected to the utility grid.
