Steps to Designing an Off-Grid Solar Power System

Are you interested in designing an off-grid solar power system but don’t know where and how to start? We have got you covered. First, though, there are multiple guides and DIYs to build an off-grid solar power system. Not many guides will bring you clarity. Instead, they will give present ideas and general information related to the off-grid solar power system. Here’s where we come to your rescue. Our beginner-friendly guide will walk through the steps to consider before designing an off-grid solar system. Additionally, Enersion’s expertise in solar power goes beyond just the regular solar panels, with the development of its own solar solution that offers 4 times the energy and half the payback period as compared to the conventional solar power systems. Let’s first take you through the steps of designing an off grid solar power system before shedding some light on how you might find Enersion’s solution more attractive.

1. Overview of Power 

You cannot move forward without understanding how much power you need. If you are not familiar with the calculations, then many online solar load calculators will help you. It’s essential to calculate the power as everything will be powered by the system. Little calculations can take you a long way and make a huge difference. 

2. Number of Batteries 

Once you have known how much power you need, it’s time to settle on the batteries. 

The three most crucial questions to ask yourself before deciding the number of batteries. 

  • Do you require 1 or 2-day battery storage, or do you need enough batteries to store 3 to 4 days of power?
  • Do you intend to store the batteries in a warm location or the cold? 
  • On days when there is no sun, will you have another source like a generator for power? 

The storage of batteries is around 80 degrees Fahrenheit. Additionally, you will have to decide the voltage of the batteries. The larger the system, the more voltage it demands. It reduces the parallel strings and the amount of current it passes through the battery bank to the inverter. 

An off-grid calculator will assist you in determining what size of batteries you need.

3. Number of Solar Panels 

After getting a brief overview of the battery, our pro-technicians will aid in getting the installation of solar panels. It is essential to understand how many hours the sun will shine through on the panel. The sun is not as powerful in the morning as it is at noon. Therefore considering all the pointers and weather conditions, you need to calculate the sun hours. 

4. Solar Charge Controller 

Having a solar charge controller will prevent your batteries from overheating and damage. It is a solar-powered voltage and current regulator. It will adjust the current and voltage, thereby sending it to the batteries. 

It is imperative to know the size of the off-grid power system to choose the charge controller. Furthermore, the charge controller is divided into PWM, i.e., Pulse Width Modulation, and MPPT, i.e., Maximum Power Point Tracking. 

PWM will charge the batteries and slowly decrease the voltage once it’s fully charged. Thus, one can easily get the desired voltage by charging the batteries. 

MPPT is a technique to observe and navigate the energy moving from solar panels to batteries. It is efficient and a tad more expensive than PWM. 

Irrespective of the solar charger you select, getting a superior quality controller for battery charging is the best you could bet.

5. Inverter Selection 

For the solar power system, the inverter is the brain via its functions. It is an essential working component that converts solar panels’ direct current power to the current usable for businesses and homes.

Alongside, inverters track the highest voltage and identify the maximum power for the operation of the modules. 

Asking a technician will aid you in the right direction. The team will examine how much watts the inverter has the capacity of holding. Before settling for the inverter, find out the voltage bank you will be having. Either way, planning at the early stage with the guidance of experts will make a difference. 

Finding the right set of the team will set apart your process and make it hassle-free. The blog, as mentioned above, sums up the five steps of designing the off-grid solar power system. There are additional steps like: 

  • How will you mount the panels?
  • What will be the size of the wire?
  • What size breaker boxes do you need? 

At Enersion, we got you covered with more than what solar panels alone offer with our expertise and novel solutions. A fact about solar panels overlooked quite often is that they produce electricity with an efficiency of only 20%. Enersion’s novel technology offers solar energy with an efficiency of 90%, allowing you to get the maximum returns from your roof space. This is possible because conventional solar power systems waste the majority of the energy in the form of heat (as the panels heat up). In Enersion’s solution, the heat is collected, and using our novel technology, it is converted to useful cooling (air conditioning) for the house or heating during the winters. This results in the most economically attractive off-grid solar system. Are you planning to install an off-grid solar power system? Let’s talk, and we would be happy to guide you through.
