The Purpose of Solar Power Systems and Why You Should Use One

Being aware of our environment and its decline isn’t enough to help save it from certain doom. Making use of what mother nature and the universe have given us can help make for a safer and healthier environment. One of the endless energy sources we have at our disposal is the ever-burning centre star of our solar system, the sun. As pulverising as it is to nearby objects, harnessing the power of the sun rather than relying on fossil fuels is one of the ways we can save our planet. This is especially true it comes to powering one’s household.

Solar power may not be as common nowadays, but it is a cleaner energy source than the grid. You can also make your appliances and devices run better because of it and you can sell some of it back to the grid if you harness more than you use. Any extra solar power you gather during the day can be sold to the grid for profit. Of course, none of this would be possible without setting up a solar power system first.

How to Set Up a Simple Solar Power System

Solar Components

When it comes to installing and building solar systems Bendigo residents have a couple of different parts they need to buy. The four major parts which you’ll find being used in solar systems Bendigo and Australia wide are solar panels, charge controller, inverter and battery pack. The other important yet not so widely known parts are fuses, breaker, meter, and MC4 connectors. Remember all of these components are essential, the latter four are just not as well-known.

Calculating

Before you buy any components or start the installation process you first need to calculate your home’s power needs. This isn’t that hard as you only need to write down the power requirements of each device. It can be tedious but it is nothing complicated. Once you have the total power consumption of all the devices add in the number of hours you use them on average in a day.

Once you do that, calculate the watt-hour of each device by multiplying the number of hours it runs for with its power rating which is stated in watts. Then sum the individual watt-hours of each device and you get the grand total of your household for a day. This is what the panels will need to supply.

Battery

Now let’s start with the battery. This component is needed for storing the power generated by the panels. When the sun sets, the panels have nothing to harness so storing the energy that they’ve collected throughout the day is crucial. You can go for either a lead-acid or lithium-ion battery, the choice depends on your budget. Batteries aren’t necessary for on-grid systems, but they’re an absolute must if you aren’t connected to the national grid and rely on harnessing all the power for your home yourself.

Inverter

A solar inverter is a device used to convert the DC power that comes from the panels into AC so that it can be used by your appliances. Once you select your inverter you’ll need to start doing actual physical work and that would be to install the solar panels.

Solar Panels

Once you have all of the above components ready to go, you need to start fixing the panels on the roof. Once you have the right solar panels, install them in a spot where there is preferably no shade at all or very little shade at best. Tilt the mounting stand so the panels face the sun. Then, wire the panels with the help of a junction box at the back of the panels. Depending on the type of panels you get, the process may vary. Regardless, you can ask the solar provider for instructions and guidance.

Connecting

When you’ve wired up the panels together it’s time you connect them to the battery. You can choose to connect the panels either in parallel or series. The former requires you to connect one panel’s negative terminal to another and so on. With the latter, you need to connect the panels by connecting one panel’s positive terminal with another one’s negative terminal and so on.

Setting Up Stands

Lastly, you’ll need to set the stands for the inverter and battery. You can either build them yourself or get solar components that come with stands. Either way, once you set them up you need to then wire the controller. Do this by wiring the first connection from the left with the controller and then the second connection from the right with the batteries and inverter. The last and final connection is connecting the controller directly to the DC load connection. Once you’re done with all the wiring, connect the panels with the charge controller using an MC4 connector and once connected the LED lights on the battery should light up.
