The sun’s light and warmth is a sustainable, plentiful and renewable power source that we’ve been making use of since the 7th century B.C. Maybe it will run out in about 5 billion years but who knows if we are going to exist on this planet then… Using solar to power your home is a great way to give back to the community, especially if you go with an off the grid system. This way you can send extra power your panels generate to the grid and get paid for it. There are multiple ways you can implement solar energy in your home. So, why should you go with an off-grid system?
Benefits of Off-Grid Solar Systems
Going off grid means you don’t have to experience all the cons of the grid – the main one being power outages. When you don’t depend on the grid for power you don’t have to worry about power outages. Why? Because powerful off the grid solar systems only rely on the sun and can’t just stop working for a while. That means you can rest assured your appliances will stay powered even when the sun is set.
While solar systems can seem like a hassle to go through when setting them up for off grid power systems its quite the contrary. With the proper set of tools, any homeowner can set up their own off grid solar system. Just take your time when doing so and you’ll soon reap the benefits of this efficient and independent solution. The price you pay upfront is higher than when you’re connected to the grid but it pays off in the long run.
The finite fossils flues that the grid relies on to provide power to your home are being depleted by the minute. This means that the cost to keep your home supplies with electricity from the grid is going to rise. This cannot happen with solar, especially if you choose to go with off the grid solar systems. No bills that will cost you more than last year’s and no dependability too. Plus, you’re using the power of the sun which is already there and it is cleaner than the one you get sent by your local utility company.
How Off Grid Solar System Works?
Just like a solar system connected to the grid an off grid solar system converts the UV rays to electricity with the help of photovoltaic cells placed in what we know as solar panels. The DC current is turned to AC with the help of an inverter and then sent to the battery. When the converted electricity needs to be used it is sent from the battery to the main electrical installation in your home through a charge controller. This controller is what regulates the voltage and keeps it at a safe level so that your appliances don’t get damaged.
What Size Off Grid Solar System Do I Need?
The size of an off grid solar system depends on the load that needs to convert and provide the household with. Consider every appliance and device that will make use of it. This will determine the number of panels you get as well as the battery, inverter, and charge regulator. Just read the power requirements of every appliance and device which is usually written on a sticker either under or on the back. The total number of devices that will be turned on at the same time will determine the peak load.
Batteries & Inverter
The peak load will also determine the battery capacity but when it comes to the voltage you’ll either go for 12 V or 24 V batteries. 12 V batteries are more common for households. An inverter will be needed to convert the DC current to AC which is what household items use. While there are three different types of inverters, it’s best you go with sine wave inverters as they are the best option for household use.
Like inverters, there are also different types of regulators and each one has three sets of terminals. Input from solar panels, output to load and output/ input to and from the battery. Alongside keeping the battery safe, a charge controller will also balance the load when there is sunlight. This prevents excess solar energy from getting stored in the battery when its full and keep the battery in reserve when the cells are not providing power.
The solar array is also a determining factor in the number of panels you’ll need to effectively power your household. The array is dependable on multiple factors such as their efficiency, the rotation and inclination of the panels, shading and dirt as well as your geographical location.
