Solar Panel Installation & ROI: The evolution of solar energy started during the year 1954. Daryl Chapin, Calvin Fuller, and Gerald Pearson began developing the Silicon Photovoltaic Cells. These cells were considered the first solar cell which can be used to convert solar energy into power on an everyday basis for all electrical requirements. As time passes, there are now several advancements in technology fields that have enabled us to acquire more solar energy than before. This energy can be used further for our homes and our commercial buildings in a more efficient and effective manner than earlier.

Cost of Solar Energy 

To make it very precise, the overall cost of a typical rooftop solar panel system for a building may range between $3,000 and $12,000. This price range depends on certain factors: your location where you live, the size of the system you want to install, discounts and incentives provided by the state governments.  STCs provided by the federal government to the customers are basically meant to offer a significant discount to the customers who want to purchase a system. If you wish to install a larger system, then the cost of the system will be higher but at the same time, the price per watt will be less. 

Factors Affecting the Cost of Solar Installation

There is no doubt that there are several factors that affect the cost of solar installation in different ways, especially if we talk about the initial cost of the system.  

• The Demand for Installations: Basically the average cost of installation fluctuates largely due to the supply and demand of the system in the solar market. It might be possible that some areas are not up to the mark or designed in such a way that the system can be installed easily. So in such cases, the cost will be eventually higher as the installers have to do a lot of effort to install your system properly. Then the other factor can be the time of the year as, during the beginning of autumn and spring season, the demand for the system is very less, so this will lead to a fall in the cost of the solar system.
• Quality of the Solar Panels: Customers often think that every single panel is of the same quality. But in reality, it’s not true at all, the composition of each panel may vary and work more efficiently than the other. So if get the previous point, now you may have understood that the materials used for manufacturing the panels can also affect the cost of the panels depending on their efficiency level. So it is always good to go for the quality and not for the cheaper solar panels as it may cost you a bit but will help you to save more and be in the long run. 
• Flat Roof: In order to get maximum output from your solar panels, the panels should be arranged in such a way towards the sunlight so that they can absorb more. If your roof is flat, then there is an option to add mounts or tilt to your roof as it will provide the correct direction for the panels. 
• Condition of the Roof: The condition of your roof is very important as if your roof is not fine enough to install panels then the installers will charge you some extra amount to work on it for installation. Generally, it happens with the old roof as they might become delicate with time and installers need to be careful while working on it. 

ROI and Savings

• Usually, solar energy systems come along with a warranty period of 10 to 15 years. This period is good enough for a system to pay for itself in a long run. Once the warranty period gets over, each kWh of the generated electricity will provide the full profit. 
• There is no doubt on the fact that solar systems are a bit expensive to install and can be considered a big investment in the long run. But in most cases, it can generate savings eventually later on. How much time it takes to provide the benefit of saving depends on certain factors like total electricity usage, size of the panels, quality of the solar panels and the weather conditions. 
• The return on investment largely depends on the feed-in tariff that you receive.  Feed-in tariffs are basically subsidies that you get for each kW of the excess electricity that you export to the energy grid. For your information, if you live in a rural area or you have a system installed before the year 2013 then also you are eligible enough to get the premium tariff benefits.

Best Solar Panel Installers In Perth WA: We all know very well why most of the people in Australia are heading towards getting solar panels installed in their homes. There are almost 8 hours of direct sunlight we get in Australia and this can be used efficiently to generate solar power so that we can save more on electricity bills. Installing a solar panel system has more advantages than we actually think of it. But before choosing the right solar panel system, you must research the best residential solar installers in Perth WA for your commercial or residential property. So here we are Future Solar WA to guide you with some important points about solar installation along with their price ranges and benefits. 

Is Solar Panel Installation in Perth a smart investment option for you?

In the past few years, it has been noted that many people have opted for solar panel installers as they are providing great benefits to the customers. To make it understand, below are some points which indicates why solar panel installers Here are some of the main reasons why choosing solar panel installers in Perth is a great saving option for you:

1) Lowest Solar System Cost:

If we talk about the system cost, you will be happy to know that Perth provides the cheapest solar panel installers in the whole world. Just for an example, a system of 6.6 kW in Perth costs you around $4500 which includes the suitable solar panel and inverter as well. Apart from this, you can also add on the best system along with the other accessories as per your requirements so as to get the best returns.

2) Low Payback Time:

Now, when it comes to the payback period, it is also very low in Perth so it will definitely be a good option for savings. To make it more clear, let’s take the example of the 6.6 kW system. So if you install a 6.6 kW system to meet your daily energy requirements and electricity tariffs in Perth, then your payback period will be around 5 years and this is an amazing investment option for you. For those people who are not familiar with the term ‘payback period’, it is basically a time period in which you receive the total cost of a fully implemented solar installer back. Always remember, the less will be the payback period, the more return on investment you get. 

3) Decent Feed-In-Tariff:

The decent feed-in tariffs offered by the government and the other companies have been the reason behind the lowest price of solar installers in Perth. Your solar installer system generates enough solar energy if it gets large roof space and more sunlight, then it will send a good amount of energy back to the grid. This will enable the customer to get more feed-in tariff in their electricity bills after they self consumed the power as per their requirements. 

How do we choose the best solar systems in Perth WA?

Basically, there are only two components in a Grid-connected System: solar panels and inverters.

Solar Panel- Solar panels are used to absorb the sunlight and generate electrical power.  

Inverter- Inverters help to convert sunlight into electrical energy which can be used to run household appliances.  You can also add a monitor which will help the system to maximize the output of the energy.  

To get the best solar system for your home, always focus on the quality, size of the system required according to your usage, and the price of the system that determines whether it is suitable according to your range. 

Few things to be kept in mind: 

• Always compare the solar panel efficiency among the preferred options while purchasing the solar system for your commercial or residential properties. Usually, the ideal efficiency of the solar system is 16-18%.
• Another point you should check while purchasing the right solar system for you is its manufacturing warranty period against the industry as it should be between 10-25 years if you really want better efficiency and ROI.
• Do check its durability while purchasing the right solar system panel for your house. The good durability will provide you with excellent system’s efficiency along with a greater return on investment in a low payback period.
• If you live in a snowy or in an area having more wind flow, it is always suggested by the installers to choose a system that grants the IEC 61215 standards. 
• Don’t chase only low price systems but always consider and compare the other factors as well like the system’s efficiency, reliability and warranty periods. 
• Before choosing the right system for your house, look out your roof space, sunlight duration and your energy usage. If you have a larger area of roof space and high energy requirements also, then it will be beneficial for you to add more and more panels. But, if you do not have high energy requirements, then you can go for the smaller solar system within your budget. 

So while concluding this, before choosing the best solar panel system, first you need to understand your energy requirement and then after that look out for the most economical option that comes along with good brand quality and efficiency for the best return on investments. Once you find the list of best solar companies in Perth, choose accordingly.

Characteristic Features of GoodWe Inverters

Now, let’s have a look at some of the silent features of the GoodWe inverters which makes them unique from others. 

• Wide Range of Hybrid Inverter Offerings: GoodWe inverters produces a large range of storage inverters which often includes the single-phase LV hybrid solutions (ES, EM), single-phase AC coupled retrofit solutions (SBP), single-phase HV hybrid solutions (EH) and three-phase HV hybrid solutions (ET). So basically, GoodWe is set to be the best option for you if you are thinking to install a hybrid inverter for your battery. 

• Multiple MPP Trackers: MPP Trackers stands for Maximum Power Point Trackers. It helps in discovering the actual possibilities of roof orientations that a string inverter can handle perfectly. If the panels are set up on different angles on the same MPPT, then the individual performance of each panel will be as same as that of the lower performing panel which will eventually affect the output. Also, The GoodWe inverters allow more MPPTs across various inverter sizes. Apart from this, GoodWe offers the only 3-MPPT single-phase inverter in the Australian market. This helps in eradicating the need of having a more expensive micro-inverter or power optimizer solution for the battery. 

• DC Oversizing: DC oversizing implies installing more solar panel capacity than your inverter’s total output potential. This may look like a wastage of power, but the oversizing by 33% can be the best option to ensure a cost-effective design. The GoodWe inverters have DC oversizing range between 33-100%. However, the clean energy councils also permit the same conditions. 

GoodWe inverters have the best advantage as they offer 98.6% efficiency and extended warranty periods up to 25 years which makes them one of the best solar inverter brands in Australia.

Important Things About Inverter Sizing: With the passing years, renewable sources of energy are getting popular due to their positive impact on the environment and people are switching to solar energy gradually. The best part is, now the government is providing certain incentives to the people who are purchasing solar power systems. And due to this people want to install bigger sizes of solar systems as they are getting support from the government. Previously, most people had a 3kw solar power system along with 12 panels. But now, the most common size of the solar power system has become 6.6kw and it is the most commonly used solar power system and is requested by the customer who wants to replace their old systems.

There are few considered reasons behind the increase in system size which also results in decreasing the manufacturing cost of solar systems.  This is also the main reason that made solar panels much more affordable for people than they were earlier. 

Since the cost of solar power systems are decreasing due to which people are switching or going for bigger size solar power systems as it has become more affordable now. The government has introduced rebates for STCs which means more panels resulting in more STCs for the customers. This will help in getting bigger discounts on the sale of solar systems. 

A 6.6kw system along with a battery is a great size system providing better value and output. A 6.6kw system means 6.6kw of solar panels that are installed on the rooftop along with a 5kw inverter. It is considered the most efficient and commonly used size of the solar panel system. 

The efficiency of the battery storage system matters the most as it converts the Direct current produced by the solar panels into an Alternating current that is used by the grid to provide power to your house. The question may arise in your mind that how does the size of an inverter affect the system’s efficiency. So, let’s discuss this issue briefly so that you can make the right decision regarding future solar installation. 

Inverter under-sizing

It has actually become a common and widely accepted practice in Australia and is sometimes referred to as the term “overclocking’.

There might be confusion regarding the combination of panels and the inverter that has been set. So, according to the Clean Energy Council guidelines and the network distributors that own the poles and lines, it is stated that the panel to inverter ratio should be completely legitimate. The rule is that you are allowed to get an inverter with 5kW capacity and add 6.6kW of solar panels as system size should be by 133%. 

Benefits of having a solar system of 6.6kW

The main reason behind the massive growth in demand for a 6.6kw solar power system size is that it provides you with the benefit of maximizing the STC and that too without upgrading your system inverter size. So eventually it helps the customer to save more if we look from the perspective for money value. It also lowers the purchasing cost of the solar power system as the 5kw inverter cost is less than the 6kw of inverters. There are a variety of ranges present in the market for 5kw single-phase inverters that pave the way for competition in the market for prices. Some of the renowned network distributors do not allow for more than 5kw inverter but they usually approve the panels oversized up to 133% of the total inverter’s capacity. So the equation will be: 5kw x 133% = 6.6kw. 

The solar system of 6.6kw will provide you with more efficient results. Nowadays it has become very ordinary in Australia to practice inverter under-sizing or solar panels over-sizing so as to get the best solar power system along with maximum output range. 

A solar inverter functions ideally along with its operating window that further includes the inverter’s specifications. As the power input coming from the solar panels fluctuates up and down, the inverter’s ability to convert it from DC electricity to AC electricity efficiently may differ. As far as the power input coming out from the solar panels falls within the range of the window, the inverter is often considered to be operating effectively. 

Sometimes your installer suggests you get an undersized inverter with your system. This is because they might have observed less sunlight is coming on your solar panels than it was expected. It may be due to a change in location & climate, the orientation of your panels, or any other factors. Therefore the best solution to this is to add more panels by installing them along with a small-sized inverter. This will lead to the better overall performance of the solar power system.  

Inverters are designed in such a way that they can handle lower power inputs than their defined capacity but there are limitations to this as well. If you think of installing an inverter that has a maximum capacity greater than the nominal capacity of the panel array, then it might be suitable for expanding your solar panel array but it is not usually recommended. This is because the overall energy coming from your solar system may be lower than from the system with the under-sized inverter. So, it is very important to ask your installer about how your system will perform if you add an oversized inverter to your system in future. Always check the balance between the systems configurations before making any decision.
