Are the Solar Panels & Inverters used by patel Electrical tested to Australian quality standards?
Of Course! All inverters installed by Patel Electrical are on the Clean Energy Council’s list of compliant inverters and power conversion equipment (PCE) suitable for installation under the Renewable Energy Certificate Scheme.

All photovoltaic (PV) modules (solar panels) supplied and installed by Patel Electrical are rated Fire Safety Class C, and can be used in both building applications and ground mounted applications, these are on the Clean Energy Council database listing,

Are all Solar Panels the same?
No, not all solar panels are the same. There are cheap lower quality panels on the market. Patel Electrical use only “Tier 1” quality solar panels that meet Australian Standards for use in the design and installation of Solar PV systems.
What Tier -1 of solar panels?
The Tier 1 ranking scale is orchestrated by Bloomberg New Energy Finance Corporation and is used to rank solar panel manufacturers in terms of their bank-ability or financial stability.

One may quite rightly make an assumption that a Tier 1 ranking has more to do with financial stability rather than product quality. But analyst who ranked it believes that the module manufacturer also meets criteria including: Manufacturing scale, Service and support, Vertical Integration, Durability and quality, Technical performance, Experience.

Patel electrical always recommend that non-solar experts buy Tier 1 panels – as it is a simple way to filter out the junk panel being sold as Top Quality.

What does PV stand for?
PV stands for photovoltaic. This is the technology whereby solar cells are used to convert sunlight into electricity.
Are all Inverters the same?
No, not all inverters are the same. There is a significant quality difference between inverters currently available on the market. Patel Electrical use only quality inverters that have been tried, tested and proven to work at a high efficiency.

Patel Electrical only installs inverters from trusted companies who can offer meaningful warranties and after sales support. Our favourite and major installed inverter is Austrian made Fronius and then Sungrow in budget segment.

What is the function of an Inverter ?
An inverter converts the DC power from the Solar panel to AC power; this is the same type of power as your mains power. It also exports any excess power back into the electricity grid. An inverter’s quality is partly measured by how efficiently it converts the DC electricity to AC electricity.
What is a micro inverter system?
Micro inverter system features a ‘micro-inverter’ on each panel which convert all the DC (direct current) power directly into regular AC (alternating current) household electricity. This avoids losses from shaded strings and maximizes a system’s power generation. In circumstances where one solar panel may be shaded, the rest of the string can still operate at full capacity. So if one panel goes down, or is not performing well, the rest of your panels can still be working at an optimal output. This is because each solar panel works independently.
Can I add Battery on my solar system in future?
Yes, all major inverter brands have this capability it’s called Ac coupled battery system. Good example of this is Tesla, LG Chem.
Can I increase solar panel size in future?
It is completely depended on the roof size and inverter capacity. You can also go for additional panel/system based on roof size availability. For more free assessment and guidance Contact Us here.
What is the best orientation of my solar panels?
The placement of panels will vary for each customer; this is dependent on which way your roof is facing, and if there is any shading or any other obstructions on your roof. At Patel Electrical we have all in-house CEC Accredited Designer, Installer, who will let you know the best placement for your panels to give you the most financial return at your property.
Does shading affect the performance of the panels?
Yes, shading definitely affects the performance of your panels. Shade from trees, roof ventilators, or antennas changes the flow of electricity through the panel, thereby reducing the performance. To maximise their performance PV panels must be in full sun from at least 9am to 3pm and must be kept free from shade, dust, and other impurities.

In homes where there are shading issues or panels have to be installed in different directions or roof orientation, we suggest you explore the micro-inverter range. Ask us if they are suitable for your requirements.

Patel Electrical will always provide you with expert solar advice, as we are Approved Solar Retailer we must adhere to the code of conduct which stipulates we must assess whether a roof is suitable for mounting a PV array. Taking into consideration what roof space is available, orientation and tilt of the panels (this affects the daily performance of how much solar energy your system may generate) and any shading which will occur and how it will affect the system performance.

Should I get my Solar Power System Serviced?
Solar PV servicing is an easy, affordable and important way to ensure that your solar power system remains safe and effective. At Patel Electrical, we recommend having a service and maintenance done at 3 year interval. Our service technicians will perform a comprehensive System Health Check and conduct a detailed clean on your system. To find out more or to book a service, Click here.
What is the environmental impact of Patel Electrical solar panels? Should I get my Solar Power System Serviced?
In Australia each kWh of electricity generated from conventional sources creates approximately 1kg of CO2. A 6.6kw solar system will produce around 8500 kwh a year which will save around 8.5 tons of CO2 emissions per year. Over its lifetime 6.6kw system will have a net saving of around 212 tons of CO2. Yes, it’s not just an environment impact but a social impact we are creating. Its helping is to go green and grow green in future.
How many years’ warranty I get for solar panel and Inverter?
The entire panels we use comes with a 25 year performance warranty, a 12-15 year manufacturer’s warranty in premium panel brand, Ultra premium panel comes with 25 years manufacturer’s warranty.

How much time does it take for installation?
It may vary based on how long it takes to get solar Victoria approval but under normal circumstances, fastest timeframe is 1-2 weeks. Once all good to go, panel installation, depending on your size of your Solar PV System in most cases the installation will be completed in less than a day. For larger size systems or commercial installations, install time frame will be advised to you on the day of booking your installation date.
Why are there so much variance in the price of solar on the market?
The price variance often comes down to the quality of the products used in the installation. Cheaper products used can mean a cheaper system price and better-quality solar products will mean paying more for the system.

Prices can also be affected by the type of service a company can provide for you. Post installation service and support years down the track.

Even with same panel and inverter price is difference because of installation quality. Installation is more important part in solar rather than products. Patel Electrical proud on our quality installation.
