Off grid Solar System
Off-grid solar implies utilizing the sun’s energy for all of your energy requirements and that the system is not fixed to the electrical grid. Installing a solar power system along with a form of energy storage, such as a solar battery, at the location of energy consumption is necessary to make this effective.
Setting in an off-grid solar system used to be an unorthodox idea because of how much space and money it needed. However, improvements in solar technology over the past ten years have reduced the cost and increased the efficiency of solar equipment, helping to mainstream them.
What is an off-grid solar system?
When someone hears the phrase “off-grid solar,” most of them immediately picture solar panels. However, in order to create a functional off-grid PV system, numerous other components must be installed.
In order to produce, store, and supply solar energy locally, an off-grid solar system must include all the essential components. Off-grid solar systems are also known as “standalone solar power systems” since they function independently from any external power source.
Off-grid solar systems, in contrast to other types of solar configurations, such as the more popular on-grid solar system, depend on batteries to supply power when the sun isn’t available.
However, compared to the solar panels they are connected with, batteries are far more expensive. Off-grid solar systems are substantially more expensive than on-grid solar systems due to the requirement for large amounts of battery storage.
What are the different applications of off-grid solar power?
Scalability and modularity, or the degree to which a system’s components may be disassembled and then reassembled for flexibility and variety of use, are two of solar energy’s main benefits.
It functions on all scales, from tiny equipment like solar phone chargers up to a grid that can operate an entire factory.
What equipment is required for an off-grid solar system?
- Solar panels
- Solar charge controller
- Solar inverter(s)
- Solar battery
- Mounting and racking system
- Wiring
- Junction boxes
How to estimate the size of solar system to use off-grid?
When establishing an off-grid solar system, determining the amount of the system you require is an early and extremely critical stage.
It will have an impact on the type of appliances you require, the amount of work required for installation, and most importantly the project’s overall cost. The size of a solar installation depends on how much power the system must generate.
There are two approaches to calculate the amount you require, and they are focused on:
- Your current usage
- Load evaluation
Solar setup size on current usage
To estimate your electricity usage in kilowatt-hours, you can conveniently refer to your monthly power bills. Then you could build an off-grid system of that size, however, you’d prefer to go a little greater (preferably, 10% more) to compensate for solar inefficiency.
Solar setup size on load evaluation
Determine your overall electricity requirements.
Start by making a list of all the equipment you intend to use, along with an estimate of how long each one will be in use. This enables you to figure out how much energy each item uses as well as how much energy you use overall per day. The size of your solar panel array and solar battery storage can be determined by calculating how many kWh you’ll use each day.
Determine the immediate load requirements.
You must also determine how many appliances you might use at once. This will assist you in determining the immediate wattage requirements that you must know in order to appropriately size the inverter (the inverter runs the AC loads).
Determine the amount of battery storage.
Determining how much energy storage you require is the next step. Do you want additional backup capacity or do you just want to cover consumption for one day?
In terms of solar battery backup, the usual guideline is that you should have enough capacity to cover at least 2-3 days’ worth of usage at the peak days of work of the year.
Develop a system based on the number you obtained from Steps 1-3.
Solar equipment manufacturers can easily create a comprehensive off-grid package for you if they know the sizes of these three important parts: the solar panels, inverter, and battery storage.
