A simple guide to build your own photovoltaic system and generate your own electricity.

Domestic solar energy installations are an increasingly popular alternative for home supply or for having an alternative in case the network fails.

Therefore, if you have done with all the necessary equipment but you have doubts about how to install them and start taking advantage of the sun’s energy, we will explain it step by step. In addition, this installation has come out for around 600 euros, so it will also help you find ideas to minimize the cost of your solar system.

 

Materials and tools

These are the materials you will need for installation:

  • Solar panels .
  • Charge controller.
  • Battery charger.
  • Mechanical handles.
  • Investor .
  • A plastic container
  • 2 AWG cable (6.5 mm).
  •  deep cycle battery of at least 12 volts.

Also, make sure you have all the necessary tools at hand. In this case you will have enough with a drill, a screwdriver, a wrench, electrical tape and a cable cutter.

Instructions.

If you already have everything ready, there is nothing left but to get down to work by following these steps:

1. The batteries, ready.

To start this project, a good step is to verify that the batteries are 100% charged and, if not, recharge them so that they are at full capacity when you want to put them into operation. While you wait for them to be fully loaded, you can start to place the solar panels and connect them so that they are also ready to work.

2. Place the batteries in the containers.

Once the batteries are fully charged, it is time to place them inside the containers. In this step, make sure that all the positives are on one side, and the negatives on the other. When you have finished, measure from terminal to terminal to be able to make the bridges.

3. Create the jumpers for the connection.

To connect the batteries in parallel you will have to make some bridges with the 6.5 mm cable. At this point it is important that you make sure that the bridges adapt to your system. Thus, if you want to use a larger inverter, you will have to take it into account in the wiring. In general, 6.5 mm cables can be used for about 100 amps. With this, if your solar inverter is 1,200 watts, you will need to use two cables per bridge.

Place the wiring and cut it to the size appropriate to the batteries. Then place the handles and connect them with the terminals of the equipment.

4. Prepare the battery cover.

Once the batteries are ready, pierce the lid of the container to be able to extract the cables that will connect to the charge controller and the solar inverter. If you prefer, you can enter the controller in the same box, although if you leave it outside you will find it easier to control it.

5. Connect the controller and inverter.

With the holes made, you will only have to connect these devices to the batteries. Before doing so, make sure that the controller is not yet connected to the panels and that the inverter is turned off.

6. Tests and final touches.

Activate the inverter and connect the solar controller to your panels. If everything is well connected, the installation should run smoothly.

With all this, your installation will be ready to start working and make yours a more sustainable home in which, in addition, you can scale the equipment to increase the capacity of your system and be increasingly independent of fossil energies.

This installation, whose original and detailed project you can consult in  Instructables , cost around 600 euros thanks to the reuse of materials (the container for the batteries, the charger and the charge controller), as well as to the purchase through the web and the choice of second-hand solar panels, which resulted in a significant cost reduction.
