DIY Portable Solar Power System: (A Complete Guide)

Building a portable solar power system for the first can be a bit confusing. In this post, I’ll guide you step by step on how to build a portable solar power system.

DIY Portable Solar Power System: Things You Need!

Here are some products you need for a portable solar power system.

1- Portable Solar Panels

First thing first, if you’re thinking about building a portable solar power system portable solar panels are the obvious component of the solar power system.

Portable solar panels are generally small in size versus rooftop solar panels so they are easy to carry on and easy to install as well.

These portable solar panels are made of solar cells which absorb the sunlight energy into them in the form of Direct Current (DC) which we convert later on into Alternating Current (AC) to charge applicants.

There are many types of solar qualities available in the market. What’s the difference between them? _ and which one is better? I have discussed this in detail in this article Click here

Just to give you a quick overview of the qualities of portable solar panels. There are two types of solar cells. Polycrystalline and Monocrystalline. The main difference between them is the efficiency rate (how much sunlight can be converted into electricity).

Monocrystalline solar panels are more efficient than polycrystalline solar panels. This means you can get more power output from monocrystalline solar panels than from polycrystalline of the same sizes.

Here’s a table of the same company’s solar panels of different types. (Newpowa) Polycrystalline & Monocrystalline.

Type Size Output Watt
Polycrystalline 58” x 26”160
Monocrystalline 57″ x 26”175

2- Charge Controller

Charge controller as it says in its name stables the voltage coming from solar panels according to battery voltage.

The power output from solar panels doesn’t come in a stable voltage, it varies depending upon the sunlight it’s getting. The variation of this voltage can be dangerous for charging batteries by using the direct current from solar panels to charge any electronics.

So at that time, the charge controller comes into place which controls the voltage output of solar panels in a very stable.

Some portable solar panels come with a built-in charge controller so you don’t need an additional one but if your solar panels don’t have a charge controller built-in so you’ll have to purchase one to run your electronics directly from the solar panels.

Just to give you an idea about charge controllers if you’re looking to shop for one, there are mainly two types of charge controllers available in the market right now. MPPT (Maximum power point tracking) PWM (Pulse width modulation)

MPPT vs PWM Charge Controller which one is best?

PWM charge controller is an older technology that is much less efficient than the MPPT. MPPT uses the latest technology and is about 30% more efficient than PWM. PWM also requires the same voltage of batteries and solar panels but MPPT doesn’t.

if you’re thinking about investing in a charge controller I would say go for MPPT which is a little bit more expensive than PWM it will be worth it in the long term.

3- Batteries or Portable Solar Generators

Batteries are simply storage tanks for power, they store the DC current from solar panels in them which we convert into AC with the help of an Invertor to charge laptops, phones, etc.

there are 3 types of batteries available in the market, here are the difference and which one you should go for.

Difference Between (Lead Acid, AGM & Lithium)

  • LEAD ACID – These batteries require maintenance and they vent corrosive hydrogen gas. these batteries are made of old technology and don’t do well now because there are more new technology batteries on the market. I don’t recommend them
  • AGM – Stands for Absorbant Glass Mat. These are the most commonly used batteries right now in the market and are 2nd best quality batteries. These batteries contain a glass separator that wicks the electrolyte solution between the battery plates
  • Lithium – These are the latest technology batteries available in the market right now which are lighter in weight and have a lower self-discharge rate.

Of these 3 types, I would recommend if you can afford, go for lithium batteries and if you’re on a tight budget then you can have AGM batteries.

Portable Solar Generators

Portable solar generators are like the latest form of batteries, they are the best replacement for standard batteries. portable solar generators contain (batteries, a charge controller, and an inverter) so you don’t need any extra electronics for the system

simply plug the portable solar panels with them through wires and the generator will store the energy in it, and then you can use the stored energy in AC output to run your applicants.

4- Inverter

the inverter is used to convert the DC current from the battery into AC current so you can run electronics. Because solar panels generate energy in DC and our electronics need AC current in order to work.

Normally batteries store power at 12V and e.g if you wanna run a coffee maker you’ll need about 110V power. So in this case the inverter will consume 110V power from the battery in order to run the coffee machine

Well there are 3 different types of inverters in the market right now (modified sine wave, pure sine wave, and square wave inverters)

in Short, Just go for the Pure sine wave inverters with chargers installed in them for your RV. other 2 are the oldest technologies and can make a damage

5- Wires

Wires are essential to building a portable solar power system, there are different wires or connectors which you’d need according to your need and the brand of panels, batteries, or portable solar generators.

here’s a list of some connectors which you’ll need

1- MC4 to Charge a Battery

How do portable solar systems work?

Portable solar panels produce (DC) from sunlight and then with the help of a charge controller we transfer the energy from panels into batteries then with the help of an investor we use that stored energy from batteries to run applicants

How do you make a portable solar system?

To make a portable solar system you need portable solar panels, charge controllers, inverters, batteries, or portable solar power generators. This combination is known as a portable solar power system or portable solar system

What do I need to set up a solar camping system?

1. solar panels, 2. charge controller, 3. batteries, 4. inverter
