What Is An Off
In its most basic definition, an off-grid solar system is not connected to the grid. It is similar to a large battery bank attached to massive power generators. In other words, it is a system of distribution and transmission lines.
Fundamentally, the grid is critical to obtain a consistent power supply. As you might already know, solar energy is a periodic energy source that is at its peak on bright sunny days and is minimal on overcast days.
The grid-connected solar system eliminates the unpredictability of power production and provides users with a sleek user experience of consuming electricity.
Meanwhile, off-grid power solutions are unquestionably ideal to utilize in locations where grid connectivity is geographically impossible. The off-grid system is considered the ideal means of acquiring an energy source in high-altitude locations and areas located quite far from the grid.
Are Solar Panel Kits Suitable For Going Off
Solar panel kits are excellent for going off-grid because they are very portable and are designed with the elements in mind. Their aluminum frames make them incredibly lightweight, and the kits can come in handy when you arent near any other energy supply source. They can help charge and operate all the basics when youre on the road without compromising efficiency rates.

Make Sure Your Panel Location Has The Proper Angles
I have written a whole separate article on the proper angle to place your solar panels, and what happens when you dont put it in the right spot. But, suffice it to say, you lose a lot of the potential power you could be producing when your solar panels are not facing due south and when theyre not properly angled. Because many homes do not have a roof lines that face directly south, it can be expensive, difficult, or impossible to face your solar panels in the right direction when they are on the roof.
Basing Solar Setup Size On Usage
You can use this option if your aim is to maintain your current lifestyle as you switch from grid-tied to off-grid solar. To do this, you can simply refer to your monthly power bills to determine your electricity usage in kilowatt-hours.
You can then size an off-grid system of that size, although youd want to go a bit bigger say 10% more to allow for solar inefficiencies.

Solar Panel Array Sizing
Fortunately, the process for sizing your solar panel array is a lot simpler. Start with your daily kWh usage and divide by sun hours in your location.
Note: for these calculations, use the initial figure for daily kWh usage, not the number from the battery bank calculations. In our example, thats 20 kWh/day.
20 kWh/day ÷ 4 sun hours = 5 kW solar array
From there, we need to add a bit of overhead to account for inefficiencies and degradation rate of the panels.
The output of solar panels drops slightly each year, which is outlined by their performance warranty. If your solar panels performance warranty guarantees 80% performance after 25 years, then their degradation rate is calculated as 20%/25 years, or 0.8% production loss each year. By the end of its lifecycle, a 400W rated panel would only output 320 watts.
In addition, solar panels are tested in ideal conditions — a temperature controlled lab with nothing obstructing the panels. In the real world, solar panels often fall short of these lab-tested conditions, meaning they produce a bit less power than their wattage rating.
Because of these factors, we budget extra solar capacity so that we reach our target production figures after accounting for the inefficiencies of the system.
20% is a good amount of headroom to account for inefficiencies. Multiply your solar array size by 1.2 to account for this:
5 kW x 1.2 = 6 kW solar array

6.2 kW array: 20 Phono Solar 310W solar panels
How Long Does It Take A 100 Watt Solar Panel To Charge A 100 Amp Battery
A 100W-rated solar panel using an MPPT solar charge controller will take approximately 12.5 hours to fully recharge a 50% discharged 100Ah lead-acid deep-cycle battery. 200 watts of solar panels is recommended to recharge a 100Ah battery in one day if the battery is used for home energy storage.
If a 100-watt solar panel connects with an MPPT solar charger, it will take about 20 hours to fully recharge an 80% discharged 100Ah lithium iron phosphate battery. 250 watts of solar panels is recommended to fully recharge a 100Ah LiFePO4 battery in a day if this battery is to be used for home energy storage.

Let’s assume that we have 300 watts solar panels, and you are planning to provide power for your off-grid home. You do not have access to the grid and installing off-grid solar on your home is your best option for meeting your energy needs.
Lets assume that each panel gets around eight hours of sunlight per day. A 300-watt panel receives eight hours of sunlight per day that will produce almost 2.5 kilowatt-hours per day. If we multiply this by 365 days per year, we will get a solar output of around 900 kilowatt-hours annually. In short, each solar panel will provides 900 kilowatt-hours per year.
What Is An Off Grid Solar System And Who This Is For
Solar power systems are great alternatives to your typical electrical systems. Aside from obvious benefits like energy-efficiency, solar power systems are also cheaper and are friendlier to the environment.
There are three types of solar power systems: 1) on-grid, 2) off-grid, and 3) hybrid solar systems. This article will tackle and focus more on the second type, the off-grid solar power system.
As in their name, solar power systems like a home off grid solar system operate on solar power. They then convert that solar energy into electricity.
Also called stand-alone power systems, off-grid solar systems are basically not connected to any electrical power grid. Because of that, they are equipped with a high-capacity battery bank to store the electricity harvested by the solar panels.
Because of the battery storage, an off-grid solar system is perfect to use in long winters, during adverse weathers or emergencies. During these conditions, there is a high possibility that power outages will occur which can sometimes last from hours to days to weeks.
With an off-grid solar system, your home will not be affected since the system can provide electricity for you. Just make sure that your solar system is designed to have the capacity to meet the electricity needs of your home.
This type of solar system is also perfect to use in remote areas located far from the local electrical grid or in areas that are prone to power outages.

Off Grid Solar System Factors
First and foremost, calculate your load. Figure out the total load of your home. This will determine the power and quality of your off grid solar system. Next, youll want to consider the battery your system will need to store electricity.
There are different types of batteries, and it depends on the appliances youll be running and your power sources. However, these systems will use lead-acid batteries, and a larger system will require a more significant bank.
As part of your solar array, youll need to consider the solar panel. Make sure that youre getting sufficient solar energy, and thats determined by the number of hours the sun is shining on your solar panels.
There are different types of solar panels available, and the most popular is monocrystalline solar panels. These generate the most electricity, but they can be pricey. For smaller loads, amorphous solar panels are a great choice.
Determine Your Energy Needs
There are three key factors to consider when sizing an off-grid system:
- Peak power demand
- Daily kWh usage
- Nightly kWh usage
To start, make a list of each appliances wattage consumption. Then write down how many hours you plan to use each appliance on a daily basis. This information is necessary to move forward with the sizing process.
Important! 1,000 watts = 1 kilowatt. Be sure to convert watts to kilowatts before you make your kWh calculations, or your numbers will be off!

An off-grid solar system is not connected to the electricity grid and requires battery storage. Off-grid solar systems must be designed correctly in order to generate enough power throughout the year and have the necessary battery capacity to meet the installed locations electrical energy requirements or demand.
In Africa, we are very fortunate with abundant sunshine. A backup generator or alternative back up power source may be necessary to supplement your electrical demand and recharge the batteries during times when the batteries are inadequately charged due to very bad weather patches or other unforeseen circumstances. We recommend that the size of the backup power source should be adequate to supply energy to your house and charge your batteries at the same time.

Sometimes The Only Feasible Option
When youre seeking to power a building in a really remote location – say a hunting cabin out in the woods – theres a good chance theres no grid to connect to at all.
If you contact the utility for a connection, they will probably tell you that you are out of their coverage area. Alternatively, they could offer to lay the wire to connect you to the grid but only at an astronomical cost.
That means that youll have to produce your own power. You could use a backup generator, but fuel for it is expensive, while renewable energy like hydropower and wind arent available in most places. This leaves solar as the only practical option for off-grid power.
