The Best Guide To Buying Solar Panels For Your Home

Categories: Review and Solar PV Panels.

Basic solar panel technology has grown in popularity. That's because buying solar panels makes it easy for you to make power during daylight. It's amazing that black cells in a flat glass fronted panel will generate electricity. 


Connecting affordable solar panels is so much easier, and quieter than using a generator. Albeit, the best solar panels only generate power during the day in sunlight.

 

But, once you try one of these solar devices, you might wonder why you hadn’t hopped on the green energy bandwagon buying solar panels sooner. The usual questions then become, "How many solar panels do I need?" and "How much do the best solar panels cost?".

If you have a battery that needs charging you can do it by setting up solar panels. In some cases you need some ancillary attachments like a charge controller, cables and of course, good daylight. That's pretty much all that you need. It’s like a magic electricity generator tray. These items are going to remove some cash funds from your money drawer. Great returns will come if you get the optimum system, but maybe not as good if the assumptions or details aren't quite right.


Of course, you may desire to ride this green wagon by investing in solar panels. But it's not something to do at any price. You might just want to help the environment. I hope the environment and saving money are some of the reasons why you’re reading this! It’s understandable that if you’re out to buy a solar installation; that you get information first. Well, you’re in luck! Here's three mini reviews of great solar panels definitely worthy of your consideration when buying solar panels. We have looked at what is out there and found three good choices. 


However, do more research! It is fine to look beyond these three products we have reviewed. This buying solar panel guide will run you through what kind of features the three solar panels brands have.

 

To save you time  the table below will take you directly to the reviews. Feel free to stop and click or read on.


Buying Solar Panels for Power Generation

Are you on the fence about why you even need a particular solar panel in your home PV system? If you're thinking about buying solar panels to install a PV system, allow me to shed some light on why these panels we have selected are handy. Simply put, these panels will let you save more money than some other alternatives.


Read through the reviews in turn. You may apply the information critically to what ever panel you are thinking about. You’ll want to get as much information as you can before you decide on a purchase option. If these short reviews are not enough, there are other articles on this website to assist you. There is a free checklist on this website to help you with what to look out for at the time of your solar installation.


It’s important that you choose buying solar panels with quality reputations. You want to make sure that your basic starting point delivers the goods. Some panels may claim to be able to give you years of free power, and no worries. They make great claims, but sometimes those claims are qualified with a list of warranty exceptions.


It’s wise to do some research on a product before you buy it. This is especially true with solar panels. Panels can range anywhere from $100’s to up to $1000’s and there is more to solar panels than price.

Choosing The Best When Buying Solar Panels

When choosing solar power panels, research as many panel manufacturers as you can. Speak with people who have already taken the leap and bought a solar system.


Here are some things that you’ll want to look for when purchasing a solar panel. It is general information.


Cell Style of the solar panel

Which of Monocrystalline, Polycrystalline, multicrystalline, or Amorphous Thin-Film Solar Panel do you select? These types of panel structure are explained in other articles we have developed.

Array Size

Most installers quotes will come with the standard number of kW size unit. The size will be optimised for whatever they sell to most customers. They will tell you that you need the standard household system. This is their optimum average size system so they suggest it will meet your requirements. It may actually be the right size, but then again, it may be simply what they have on offer.


You want to find an installer that will show you why a smaller or larger system won't work as well. Ask about their assumptions and use numbers and facts for choosing the panels you buy. It is possible the size of array proposed is the right one; trust but verify.

The Balance of System For Best Solar Panels?

What is the 'balance of system' (BOS)?

It includes all the components of a PV system beyond the solar panels. That means it includes the wiring cables and connectors, disconnect switches and fuses, the solar panel mounting system, the inverters that come with or without maximum power point tracker, the charge controller, and the rechargeable battery bank, sensors and monitoring software.

Inverter

Inverter pricing has been reducing and their features expanding exponentially. The inverter power size needs to be matched to the panels’ output.


Racking and Roof Features

Installers might not have a variety of options available. You should choose panel racking that will last a long time and won’t compromise the roof. Racking lets the installer adjust the positional setting of panels as they fit them to the roof. Ideally, you’ll want racking that can be set up and installed quickly. You want the whole system to stay fixed for beyond the life of the panels' warranty.


Also, ensure installers use a roof tool enabling them to raise or lower the panels without damage. The panels look better when completely parallel to the ridgeline.


Wiring

Install all electrical wiring and connections using a licensed electrician. They can supply a quote to do the supply and install of their wiring. You will get the electrical connections working diagrams with your solar system. They will make your electrician's job much easier.

​What Solar Power System Backup Do You Need?

Do you need to think about backup?


Like all natural power systems, the output will depend on the weather.


What if there are a series of ‘no sun’ days?


If you are linked to the grid then you are tied to the grid for back up. So, no problems.


What are your options when the grid goes down? If the grid goes down you have no power.


The panels aren’t permitted to supply solar power to the house if your panels are tied to the grid. When it blacks out your solar panels are locked out. Fortunately for most people that is infrequent.


You are going to want to decide what is more important to you.


Do you want the ability to use power 24/7 even during main power outage?


You can do that with or without being tethered to utility, or an extension cord plugged into a generator. You want to be able to work without having to stop when the grid does.


After buying solar panels, you might have to buy a rack for a battery storage bank.


Batteries & Charge Controller 

This expense depends upon the nature of the solar system.


Vanadium Redox Flow and Lithium batteries prices have been falling year on year. Their technology improves yearly. 


For locations with irregular power a battery storage system may be a worthwhile investment. It will be prudent to do a cost analysis for the battery purchase separately.
