Grid-connected systems allow you to keep your connection to the grid in order to purchase power at night (and when its cloudy). Your solar inverter will work in tandem with grid electricity to intelligently use all solar power before taking power from the grid. Grid-connected solar systems also allow you to sell electricity back to the grid. In general, it is not practical or economically viable to unplug off the grid entirely.
Off-grid systems are self-contained power sources that use solar and batteries to offer 24-hour electricity without the need for a grid connection. These are more frequent in new development projects in rural Australia, where homes might be quoted for more than $50,000 just to connect to the grid. In some cases, it may be more cost-effective and ecologically friendly to install a Solar and Battery stand-alone power system to support the new home. It will have a high initial cost (often at least $25,000), but power will be free for the rest of its life.
Hybrid solar systems are grid-connected installations that contain a solar battery to store and reuse solar energy when there is no solar electricity available (i.e., night-time). Solar batteries offer a fantastic backup power supply as well as the opportunity to make better use of your solar power, but at their current prices, they do not deliver a good return on investment. In fact, none of the 48 scenarios we recently modelled throughout every state in Australia had a payback duration of less than 8 years, and the majority had a payback period of more than 20 years. Given that the average lifespan of a modern battery is 10 years, it’s easy to see why less than one in ten houses is now installing a battery with solar.
How Does Solar Power Help You Save Money?
To determine whether it is a reasonable investment, you must first understand how having solar panels installed can cut your electricity expenditure.
1.Compensating for your energy use
The major method solar can help you reduce your energy costs is by lowering the amount of electricity you need to buy from your electricity vendor, which normally costs between 15 and 40 cents per kWh. A grid-connected solar system prioritizes solar energy while also supplying any leftover energy needs from the grid in a harmonious manner.
Depending on how much of their electricity is spent during daylight hours, a typical home can expect to offset 30 percent to 70 percent of their energy usage with solar panels. By using a battery storage system, this offset ratio can be increased to near 100 percent.
2. Feed-in tariff for surplus energy
Because the amount of energy generated by your solar panel system is determined by the sun rather than your energy usage, there will be periods when excess energy is generated and can be sold back to the grid at a rate known as a ‘feed in tariff.’ These feed-in tariffs differ depending on your state and whose electricity company you choose. Typically, feed-in tariffs range from 3 to 12 cents per kWh. The size of your solar system normally limits your ability to get a feed in tariff.
After solar is installed, you will notice a reduction in the amount of energy you purchase on your power bill, as well as an added line item for the Feed-in credit.
Some strategies for encouraging self-consumption
Increasing your solar energy self-consumption will lower your energy expenditures. Consider using a timer on popular household equipment to increase your return on investment.
How much money will I save on my energy bill?
To determine how much, you will save on your energy cost, you must first choose the appropriate system size for your needs. As previously explained, you save money by offsetting the quantity of electricity you buy (self-consumed energy) and selling electricity for a feed-in tariff. Understanding how much solar energy you will self-consume is vital in evaluating your savings because there are varying rates for purchasing and selling electricity.
Choosing high-quality solar equipment
You’re probably worried about how to choose solar panels for your home by this point. As with all purchases, there are high-quality products, low-cost products, and cheap and ugly ones that will cause more problems than they will solve. Solar is a long-term investment, and because it requires experienced electricians to repair and replace equipment, we recommend sticking with reputable brands. GoRun Solar guarantees to meet all of your solar needs and to provide high-quality labour.
A solar power system is made up of four major components:
· Panels for solar energy
· Solar inverters
· Mounting or racking
Solar panels are the first component.
Solar panels are little more than a group of 60 or more solar cells. Different cell kinds and cell configurations can be used in panels.
They are also available in two sizes: 60/66-cell “household size” and 72-cell “commercial size.” Despite their titles, either can be used on a residential roof.
Commercial-sized panels are larger and heavier than “residential-sized” panels. Their advantage is that they produce more watts, allowing you to get more electricity from fewer panels on the roof.
Their bulk and weight, on the other hand, make them more difficult to work with. This means that the installer will have to spend extra time ensuring that the installation is compliant. Our experienced and efficient installers will have this part done seamlessly.
The second component is a solar inverter.
The inverter is the second most important component of a solar power system installation. They are available in two major varieties:
A string inverter around the size of a suitcase
Microinverters, about the size of a standard book.
String inverters are mounted on a wall, and all solar panels are connected to them. Microinverters are installed on the back of or next to each solar panel.
There is also a third choice known as ‘power optimizers.’ These are a mash-up of the two. An optimizer system includes a string inverter mounted on the wall as well as optimizers on each panel.
Racking or mounting is the third component.
What is the connection between your solar panels and your roof? The racking.
At the end of the day, racking is nothing more than aluminum screwed together.
They allow for greater design freedom in the system and may corrode less over time.
The price difference between a budget end brand and a premium end brand is approximately $100 per kilowatt.
Consumption Monitor is the fourth component.
Consumption monitors are little gadgets that can be found in your switchboard. They cost roughly $500 and are used to determine how much electricity is arriving from or going to the grid.
To be precise, a solar system can be installed without a consumption monitor. However, we strongly advise you to install one. This is because the inverters, out of the box, will only tell you how much solar energy your system produces.
You will not know how much energy your home consumes, or when. Your monitoring app will become far more effective if you invest in a consumption monitor. It will reflect both consumption and production.
It is important to have a good installation expert to install your solar panels. A bad installer might take reputable brands and make a mess of the installation.
Such systems not only look awful, but they can also be unreliable, underperform, and be dangerous. Keep in mind that solar systems can have up to 600 volts flowing through them. The installation is crucial. GoRun Solar will supply you with dependable and well-trained expert installers to make the installation process simple and efficient.
The fundamentals of roof direction/angle for maximum solar energy output are:
Let’s get to the fundamentals as to in which direction should solar panels be installed? The sunrise is in the east while the sunset is in the west. So:
- East-facing panels will produce more energy in the morning.
- In the late afternoon, panels facing west will produce more.
- North-facing solar panels will provide the greatest energy overall, but less in the morning and late afternoon when compared to east and west-facing panels.
- East and west-facing panels will use roughly 15% less energy per year than north-facing panels.
However, a functioning household can self-consume more solar power with east and west-facing panels because they create more energy before and after school/work, expediting the payback of their system when compared to a north-facing one.
It used to be that if you couldn’t install panels on a north-facing roof, a solar power system wasn’t worth the investment.
With solar power system prices so low, you may obtain a great return on investment from east or west-facing panels, or a mixture of north, east, and west.
Angle of the Solar Panels
The optimal panel angle for maximizing energy production over the course of the year is determined by your location. Don’t be concerned if you can’t put your panels at the right angle. Unless your roof is flat, the best angle is whatever angle your roof was built at. If your roof is flat, you can still place the panels flat–but you’ll lose around 10% of your total yearly generation, and you’ll have to pay someone to clean them periodically (about 3-4 times a year), because rain needs to run off the panels and cleanse them at least 10 degrees tilt.
What number of solar panels should you purchase?
Because solar installation costs have dropped significantly while electricity costs have risen, the answer to this question has shifted in recent years.
Your only constraints are your budget, what your roof can adequately accommodate, and how much your local electrical network (DNSP – Distributed Network Service Provider) lets you install.
The bare minimum for most households is 6.6 kW of panels (about 18 total) with a 5kW inverter. Don’t stress, GoRun Solar will assist you with this process.
How to Calculate the Savings and Return on Investment of a Solar System?
The amount of money you will save by using solar power is determined by a few factors:
- The kW rating of your system size
- The output of your solar power system (which is fairly steady when annualized!)
- This is your ‘self-consumption ratio.’ This is the amount of solar electricity you utilize at home vs how much you export to the grid.
- Feed-in tariff of your choice. These differ from one vendor to the next and from one state to the next.
- Your use fee, this is the cost of grid electricity.
So, the primary method solar energy saves you money is by offsetting your grid electricity consumption.
Assume you pay 36 cents per kWh and your solar power system produces 1kWh to compensate. You’ve just conserved 36 cents.
But what if your system produces a kWh when your house doesn’t use it? It is fed into the grid, and your retailer compensates you with a feed-in tariff.
Here are some examples of payback calculations for a 6.6 kW installation. They’re from our solar calculator, and they’re based on typical prices and usage patterns:
- Sydney: three years
- Brisbane: three years and two months
- Canberra: Five years and three months
- Perth: Four years and five months in
- Melbourne with the VIC rebate: two years and six months
- Melbourne without the VIC rebate: three years and six months
- Adelaide: three years
- Darwin: six years and four months
- Hobart: Six years
