Off grid solar power systems

For houses in remote locations where there are no power lines, solar power is a great solution. An off grid solar system provides you with energy throughout the whole day and the battery bank is there for the nighttime. 

What is an off grid solar power system

There are three main types of solar system: grid-tie, hybrid, off-grid. They differ in their connection to the commercial grid and the components. Grid-tie and hybrid systems are connected to power lines and you can either draw the electricity from the grid or sell your excess energy into it. Off grid solar panel system, as the name entails, doesn’t have a connection to the power grid whatsoever. Your house is powered solely by solar panels and a battery bank.

Mobile solar installations, such as RV and boat solar systems, also fall into off-grid solar power systems category. Vehicles and vessels sometimes already have their own house batteries. The energy needs of a boondocker or a sailor are relatively low and even one powerful panel can be enough for everything you’ve got. Keep in mind that warranties for PV modules generally apply only to residential systems.

Advantages:

  • Great solution for remote locations. A photovoltaic system is a good alternative to gas generators that are commonly used for remote houses, RVs and boats. Solar panels don’t need fuel, they don’t make any sound or smell. They work as long as there is daylight and last for over 25 years. 
  • Full energy autonomy. With an off grid solar system for a small home, you don’t depend on utilities and their policies. Since you aren’t connected to the grid, power outages aren’t a threat. Having an off-grid system proves to be especially advantageous in times of natural disasters when power lines are often down.

Disadvantages:

  • No net metering. Selling excess solar energy into the grid is the main way in which a solar system brings you money. Since there is no grid, it’s not an option and you can’t really do much with leftover kilowatt-hours. 
  • A battery bank is expensive. Off grid solar power systems for homes always require batteries since that is what keeps your house powered at night and on gloomy days. Lead-acid batteries are the cheapest option but they are fragile and inefficient.

An off grid solar system kit includes:

  • solar panels;
  • off-grid inverter;
  • charge controller;
  • batteries.

Off grid solar system wiring diagram

Here is a basic scheme of an off-grid system. Note that batteries use direct current that is coming from your panels. The inverter draws DC from the battery bank and converts it into alternating current that is suitable for house appliances. 

A charge controller is often overlooked but it’s important to add it for the safety of your batteries. It protects energy storage from high voltage for solar arrays and prevents overcharge and deep discharge. A controller is relatively inexpensive and it significantly prolongs the lifetime of your battery bank. 

Off grid solar system cost

Your expenses will primarily depend on the size of your installation, panels that you’ll choose and your battery bank. Chinese solar panels, such as PV modules from Jinko, JA, Trina Solar, are the cheapest. American-made panels are slightly more expensive but the quality is higher. The most advanced PV modules of the highest quality come from brands like LG, Sunpower, REC, Panasonic, but going for them will significantly increase your off grid solar power system’s cost.

Pay attention to controllers and batteries as well. PWM controllers are cheaper and simpler than MPPT regulators. MPPT controllers, on the other hand, are much more efficient and they fit all kinds of systems. When it comes to energy storage, lead-acid batteries are cheaper, but lithium-ion ones last longer, provide higher efficiency and allow for deeper discharge.

Frequently Asked Questions

How do I choose the right system size?
Your utility bills contain the energy consumption data for your home. All you need to do is divide the daily figure by the number of peak sun hours in your area. The result will be a gross estimate of a system size needed to offset 100% of your energy needs. Please refer to our article on sizing solar panel systems for more detailed instructions.
How do I know if a system is good for my house?
You can browse through our catalog and pick a system with desired power output and functionality. Our engineer with 20+ years of experience will adapt it based on the information you provide. He will take into account your location, roof pitch, house orientation and other factors. You don’t need to know a single thing about solar – we will support you at every stage.
Which system (grid-tie, off-grid or hybrid) will work for me the best?
It is impossible to give a good recommendation without knowing any details, but we can share the general principles. A grid-tie system is the standard choice: it is the most affordable and lets you take advantage of net metering. You need an off-grid system if the grid is unavailable or full independence is desired. A hybrid system is a mix of the two, performing equally well with and without a grid connection. You can find a more nuanced take on the difference among the three types in our article.
Does a solar system include all that is needed for installation?
Yes, our systems include absolutely all components. You won’t need to buy any extra parts to install it and start generating power.
Will you install the solar panel system for me?
Currently we do not provide installation services. You will need to contact an independent solar installer.
Do you offer a warranty for your solar panel systems?
All components of our systems come with a manufacturer’s warranty. We also stand behind the work of our engineers who configure the systems and guarantee full compatibility.
How can I get my system?
We work with the top freight carriers like XPO, FedEx, ODFL, R&L, etc. We also offer a free pickup option so that our clients could get the equipment cheaper and faster. Note that pickup is dependent on the availability of equipment in our fulfillment centers, and may not be feasible in your location.
Do deliveries of solar panel systems take longer?
We deliver our systems as fast as the rest of our equipment. Typically it takes 5 to 7 days.
Do you have all the displayed systems in stock?
Yes, we offer full transparency and update the availability of items in real time.
What is the benefit of buying a solar panel system compared to buying all the equipment element by element?
Our systems are configured by an engineer with more than 20 years of experience. We will adapt the kit to your conditions and ensure compatibility.
Does a solar panel system come with a plan or a manual?
The equipment manufacturers normally provide user manuals for their products. These can be accessed via our website or the official websites of the respective manufacturers. Aside from that, we do not provide any other materials, but we're ready to consult you along the way.
