SMART SOLAR SYSTEMS FOR HOMES AND BUSINESSES

Generating energy from solar is a good investment for many reasons.

It reduces your environmental footprint, saves you money and can increase your property value. A well designed solar power system on average has a payback in Sydney of 3 to 5 years. A quality solar power system will last decades, so getting a return of 20% on your initial investment is possible. This makes solar energy one of the best financial investment choices on the market. A typical solar system comprises two main parts, the panels, and the inverter. Solarpro typically installs top quality, high energy efficient panels like LG and SolarEdge. The panels you choose are usually combined with a SolarEdge optimised inverter to deliver award winning performance. While solar panels are important and very visible, the heart and brains of solar systems is the inverter. It converts the direct current the solar panels produce into a usable alternating current that the appliances in your home or business use. There are three different inverter technologies available, string, micro and optimised. We have provided more information on the significant differences between these three technologies further down the page.

Even a small shadow can be a big setback for the solar system output, if the wrong solar design is applied. Solarpro can solve such issues.

THE 'SMART' SOLAR SYSTEM

A smart solar power system has a centralised inverter controlling it. The inverter has a small computer in it that allows you to do all kinds of amazing things with the free energy you generate.

Optimisers are used to enable each panel to operate individually unlike a string system. Because panels sometimes face different directions and some get a little shade from surrounding vegetation, having each panel operate separately can improve solar power system output significantly.

Did you know with a string design, where let’s say 10 panels are all connected in a string, if even 1 panel is shaded all panels in that string will lose significant output. On the Northern side of Sydney, with our leafy outlooks, getting a roof that never has any shade, from antennas, gables, satellite dishes or trees is very difficult. That’s why string inverter solutions are often not suitable for a solar system that requires a high electricity output. In these instances, optimised technology is the right solution. Off the shelf, it will generate more power than other inverters purely due to the architecture of the system, which could be reason enough for installing the system. Or, you may be the type of person who wants to take full control of your home’s energy and integrate some energy control devices into your solar system. We have the technology to  give you these options.

THE ADVANTAGE OF DEVICE CONTROL INTEGRATION

Solarpro will design a smart solar power system that not only generates renewable energy, but also can create integration with other energy consuming devices in your home. 

Turning your house into a Smart Home. The inbuilt computer enables you to take control of your home’s energy down to each switched appliance. You can programme appliances like the air conditioner or a pool heat pump not to come on until there is enough excess solar energy being produced. You may like to have your underfloor heating or heated towel rails on a solar-powered timer so they are warm and ready when you want them.

Electric hot water tanks are popular in a smart energy solution, because we can direct the excess solar electricity directly into your tank. A very cost-effective way to power a solar hot water system. Solar-powered EV chargers can also be integrated into this solution to ensure you can use the sun’s energy to drive your EV, rather than the grid if you choose. The ultimate goal is to use as much as possible of your excess generated solar power, instead of selling it back to the retailer for a few cents, keep it in your property and offset your other electricity needs.  The result will be that you import as little as possible from the grid and stay “off the grid” longer than ever. Combine all this technology with a home solar battery and now the grid is only there to back you up. Your solar system is now the main supplier of the energy for your home. You will also be able to monitor how much energy your home uses or exports to the grid at a glance. Energy control in the palm of your hand.

TURN YOUR HOME INTO A SMART HOME

A correctly designed solar power system will generate excess energy, often between 11am and 3pm. Designed to automatically use the PV system’s excess power to increase solar energy usage, smart energy products help the homeowner achieve lower electricity bills, increased energy independence, and greater convenience. The smart energy suite combines solar power production, solar storage management, and home automation, all under the control of a single  inverter. These smart energy products feature wireless communication with the inverter and are ideally suited for a variety of home automation applications. The system lets you decide what is done with that energy from heating hot water to powering domestic appliances or a pool pump. This will lower your electricity bills and you can manage it all on the run from your phone or just set it and forget it.

FAQs

What is the difference between simple solar and smart solar?

Standard “Simple” Solar has been occurring in Australia from about 2007 in larger numbers, however it grew to bigger numbers from about 20010 to roughly 2019, and the cheap systems on offer still now are not that “smart”.

Now what exactly is simple solar you may ask?  It’s simply when an installer puts a solar system on your roof and you then try to use as much of the solar electricity as possible during the day.

While this type of renewable energy is able to create a saving for you and allow you to achieve a lower bill, it puts all responsibility to achieve the best o financial outcome into your daily behaviour.

The issue is that the electricity generation of a system in the morning hours is usually only 20, or 30% of what the system can generate in the middle of the day. So the generation is following a curve and peaks in the middle of the day, which means that your consumption, which isn’t always in the middle of the day, doesn’t necessarily match the generation of electricity from your solar system.

To understand the difference between this solar application and smart solar is very useful. This is because what smart solar is now doing is find other ways to utilize that solar energy peak which is generated from 11am to roughly 3pm in Sydney.

There is usually some overflow excess electricity when the system generation peaks and the way we can use smart solar is by sending that excess electricity, either into a hot water tank for generating hot water, or we can also use it in a storage device that then, later on, can give off heat in the later parts of the day to heat the home.

So smart solar is really utilizing the generation of solar electricity that is the excess capacity during peak production periods and it works to avoid sending it back into the grid for a low feed in tariff value, contrary to what “Simple Solar” does.

Of course, the one well known way to implement smart solar is simply to have a battery and then store your energy until it is needed, releasing it at any time, but some of the other options Solarpro has developed can undertake a similar outcome, for a lower outlay.  Call us, so we can develop a customised smart solar proposal for you.

What are the key advantages of smart solar systems?

The key advantage of a smart solar system is that it simply allows you to reduce your electricity bill further because instead of exporting the electricity at roughly six or seven cents per kWh in Sydney, , you are now able to keep  the electricity it in the house and utilize it, therefore creating a higher value.

For example, you would be able to use the excess renewable energy to divert it into a hot water tank, which would mean that you wouldn’t have to pay the grid electricity price per kWh to create the hot water. Therefore, overall, you would have a better financial result.

Can I have a 0 dollar electricity bill with a smart solar system?

A smart solar system, depending on how many components you have connected to the smart programming infrastructure will be able to get you closer to a $0 bill than just a standard solar system.

You will always have to pay for the electricity that you’re getting from the grid in the evening and at night, as well as for the energy retailer charge that is called the supply charge. The supply charge is the money one pays for the right to be connected to the grid and this charge, which in Sydney is around $100 for a three month period is supposed to go towards grid maintenance.

So in order to get a $0 bill, you would have to export enough solar at 6 to 10cents per kWh to offset all your night’s use as well as the supply charge, which is very rare.

On the other hand, if you have a smart solar system and you have for example a battery, this would mean not many kWh of electricity would come from the grid at night, as you would utilise your battery power 1st.

So the only cost you have to offset for your solar system is the supply charge of about $100  per quarter. This means that if you export a hundred dollars’ worth of electricity in the quarter via the feed in tariff,  you could actually have  close to a $0 bill. Therefore, with smart solar and home integrated solar, it is easier to get a $0 bill then with a standard simple solar.

What has changed regarding smart solar over the past few years?

We’ve now got other technologies that we put into the solar system, where we can divert that energy straight into something like a hot water tank, or a swimming pool heat pump, or a pool pump, or even an air conditioner. Gas is becoming a thing of the past. We’re now recommending people install an electric hot water tank, instead of a gas hot water system. We’re now heating swimming pools with electricity rather than gas, because we can now control the costs and the energy that goes into it by coupling these devices with PV solar.

The problem with gas is, we’re stuck with a company that’s going to dictate how much you’re paying for your energy. With the sun, that energy is yours. And once you put those solar panels on, it’s costing you nothing. So as time moves on, we’re now recommending to people to keep away from gas. We’re putting electric appliances in like electric hot water; we’re heating swimming pools with electric heat pumps. We’re now driving cars that use electricity. So, you want to be setting your home up correctly now, to have as little running costs as possible, so the future is Smart Solar.

What is a feed-in-tariff?

A Feed-in Tariff (FiT) is a payment made to a renewable energy source, such as wind or solar panels, for electricity fed into the supply grid. FiTs can be mandated by the government or voluntarily offered by an electricity retailer.

FITs’ primary objective is to motivate the use of renewable power. FiTs end up making the installation of renewable energy systems more reasonably priced for the system’s holder. They accomplish this by lowering repayment times through energy fee savings.   Using a FiT to stimulate demand, governments not only financially assist early adopters, but also start driving the industry to make new and efficient systems.

FITs also motivate energy consumers to use less energy. Some users directly benefit by being credited for electricity generated in excess of their own needs. Others become much more aware of their energy consumption as a result of installing their own electricity system, and this may lead to a change in behaviour to reduce their energy consumption. Individual users can save money on their electricity bills thanks to these two factors.

Following installation, the user can apply for a FiT with the relevant state authority and/or electricity distributor. They can enter into a contract to receive the FiT for the electricity they export to the grid if their system meets certain criteria. In Australia, the large percentage of contracts are for a set period of time, up to twenty years in some cases, and for either gross or nett metering. Contracts are only valid as long as the customer stays at the same address and uses the same electricity supplier.

How do I maximise my solar savings?

You can begin your new journey once your installation is complete and your metre has been reconfigured by your electricity supplier. It’s time to switch to clean energy in your daily life. If you follow certain guidelines, will be ensured that you get the most out of your solar investment.

You first need to understand that solar panels only generate electricity during the day; therefore, if you want to maximise your energy usage, you should try to use as much free electricity as possible while the sun is shining. While the amount of energy required varies from household to household, there are some simple ways to ensure you are getting the most out of your solar investment

Also, the number of appliances you can use during the day is defined by the type of solar system you have or the amount of power your household requires. However, as a general rule of thumb, using one appliance at a time can save you a significant amount of electricity. This can be intimidating for those who aren’t used to limiting their appliance usage. However, by following simple suggestions, the practise can be made extremely simple such as only turn on lights in the rooms you are using.

Secondly, in most cases, you will not need to climb on your roof on a routine basis to wash your solar panels. However, it is possible a good practice that you clean them every few years. The number of times they will need cleaning is determined by a variety of factors, including where you live. Dirt, mould, sea salt, and animal droppings all reduce the amount of sunlight that your solar panels can absorb. This can have some impact on the output as it can reduce your panel’s ability to absorb light.

Nevertheless, we are talking in the vicinity of 5 to 8% loss on some panels that have not been washed for some years, not 30 or 40%, so if you do not clean the panels and have a sufficiently large capacity system, you will generate s lot of savings.

Finally, monitoring your solar system and your home’s energy demand will assist you in keeping your solar experience as rewarding as possible. Apps that track your energy consumption can be linked to your solar inverter and panels, in case of SolarEdge and they can show your daily household electricity consumption and system generation.

Why is a solar site inspection important?

There are many different reasons that a solar and even battery related site inspection is important when proceeding with a system installation.

Firstly, by asking tough questions, you can look the company representative in the eyes and assess their competence. If they are unable to respond, make excuses why the can not come out, move on. Furthermore, by not wasting time on companies who can not be bothered to look at your roof and your particular circumstances you will kick out the cheap and nasty businesses who can’t afford to send somebody there and just want to fluke it, get someone to knock it on your roof, and leave.

A site inspection is a basic must have, as it allows the responsible solar company to identify any potential problems with your roof. For example, if your roof is more than ten years old, some deterioration might have occurred and in some cases these matters would need to be addresses before solar panels are installed on top of a potential issue.

Furthermore, with the identification of issues, high quality installers will also be able to identify where your roof has the most and least shading, giving you a brief overview of where your system would go, which direction it would face, and the size of it.

Finally, a proper site inspection will allow the installers to tell you where the different components, such as the inverter would be ideally located, and if your current switchboard is suitable or needs an upgrade.
