Solar Panels – What You Need To Know
This guide provides valuable information If you’re preparing to get quotes for solar power, on the key components of a system installation the renewable resources.
Before we delve into the facts which are the best solar panels to choose and the amazing world of PV modules, It is important to make sure that we are talking about the right solar panels.It is also necessary to get any confusion and misconception out of the way. This website Ultimate Solar Energy is dedicated to solar PV also known as photovoltaic solar panels or “Solar Energy” modules some people call it solar panels Melbourne either of the one if correct.
Let’s talk about the solar power heating as There is another type of solar panel (as opposed to generating electricity) is used for heating up your water for daily life usage. You will wonder what these type of panels are called so one of them is termed as solar thermal collector and other is “solar hot water panel” and is a completely different beast.
These videos will help you understand both of them easily , I would recommend you to watch both of them rather than reading further where the difference has been explained very well.
If the conclusion after watching the video to you is that solar hot water is preferable to you, then it will be better if you switch to another website that is dedicated to solar water heating .
So now we have realized that we probably should jump in!
the most critical part of any solar power system are Solar panels and for Melbourne users they would want specific information regarding the pv in Melbourne. It is important to choose the best type and brand for your requirements is just as necessary to make sure they are installed by an authorized and trained competent accredited installer that covers the right angles and point to the optimal direction so you get the maximum possible power from it.
It is unfortunate that most of the sales people aren’t going to be a whole lot helpful when it comes to choosing the best solar system brand in Melbourne! Why? Because, most of them will use the sales strategy to insist that their solar panels are of the best quality and everyone else is selling crap modules which is most of the time just a strategy more than anything else despite my best efforts to persuade them otherwise
So what’s the truth As we all know they can’t all be right! How do we purchase choice that is best for your circumstances and make an honest solar panel comparison? We will come back to it.
Points To Consider when Choosing Solar Panels.
When you are looking to shop around to get the very best from your solar panel rebate, one point you need to consider is that you should set different installers apart by the brand and type of PV module they offer to you.
So what is your assessment which are the best solar panels for you? We have discussed some of the factors you should weigh up in making your choice:
When looking up how much solar systems cost, the first calculation you need to make is: How many watts you are getting of electricity per dollar of module, or alternatively, dollars per watt?
When we talk about some of the decent solar panels, not including other system components or installation, can range in different prices from around 67 c to $1.59 a watt; inclusive of General Sales Tax.
Like most things in life and as a general rule, you do tend to get what you pay for – so be cautious about choosing solar panels just considering it’s low price as low cost could translate to poor reliability and performance. Some suppliers are just more competitive and there are often bargains on quality products to be had, special deals.
Just make sure that you are comparing apples to apples in terms of service, warranty, product quality and more.
2. Solar Panel Efficiency
When we talk about efficiency, we refer to the ratio of the energy (as a percentage) in the sunlight that hits the panel cells to the electrical energy generated by the module.
For example, the solar panel efficiency would be 50% if the solar panel captured half the energy in the sunlight,
In real-world conditions, conventional panel efficiencies are somewhere in between 12% and 21%.
Well, the higher the efficiency, the more watts of electricity you will get per square meter of panel that makes high efficiency good?. So, the higher the efficiency – the smaller that solar panel becomes for the same electrical output and the less roof space required.
The only disadvantage of high efficiency solar panels is that they are a bit more costly in price.
You should look into higher efficiency modules as your best choice if roof space is at a premium, or you just want super-duper PV technology,. in other cases, as long as the panel efficiency is over 15% or more than that then don’t worry about it.
- PV Module Warranty and Quality
It is not easy to determine the quality of inverters, solar PV panels and installation service from a quote – and as mentioned, salespeople tend to not give you the right information all the time. The first thing I would do to rate a panel brand is to look at the reviews of solar panel that I have collected from Australian customers over the last few years; so you’ll get a good idea of how different modules perform in australian conditions. These reviews are only from locals who have had the panels installed for at least 12 months.
You can also take a look at solar panel comparison chart to view pricing and specifications of various popular brands and models side-by-side, or view our chart of solar panel brands I trust for a recommendation on the choice of modules available in Australia
The next thing to realise is warranty statements and conformance to quality standards give a pretty good indication of a solar panel’s quality.
Pay particular attention to the fine print concerning issues such as where you might have to send your modules if there is a problem, whether they are fully standards-compliant and approved for use in Australia, plus the experience of the company supplying you. Will they be around in 10 or 20 years if something goes wrong?
As an absolute minimum, insist on at least 10 year manufacturers warranty (also called product warranty) on the modules. Be aware that this is a different guarantee to the 25 or 30 year “performance guarantee” that every solar panel out there carries. Without getting into details, the performance guarantee as it is so easy to wriggle out of is almost worthless. The manufacturer’s guarantee is the one that you need to look at and it needs to be at least 10 years. This blog post covers solar panel warranties.
Finally, make sure the warranty isn’t tied to an expensive service contract every year or two. You don’t want to be compelled to shell out $500 a year for a bloke to hose down your panels just to keep your warranty! By the way, this sort of warranty stipulation is likely unenforceable under Australian consumer law!
Some people say that the German solar panels are the best and all Chinese solar panels are crap. Frankly I find that talk borderline racist. As far as quality is concerned some Chinese brands are just fine, great even you may have reasons for not buying Chinese products and I’m not going to get into a debate on it. However,. Some are crap, but if you think “Chinese” is synonymous with “low quality”, Then your iPad or your Macbook Pro are also made in china these days so what you thing about them? Yep, made in China…and they’re both pretty high-quality, sophisticated devices.
