What are solar systems?

At first, this recent phenomenon of solar panels may confuse people. How does it work? Is it safe? It must be expensive! The advantages and disadvantages of solar panels? Best solar panel company? Solar panel systems are a modern way of supplying our homes with transformed energy from the sun which creates electricity to power our appliances. A step-by-step guide can be found below on how solar power systems work.

How Do Solar Power Systems work?

A four-step guide on how solar panels work:

Step 1 Solar panels react to light from the sun
Step 2 Inverters transform the power into electricity
Step 3 Electricity flows into a net meter
Step 4 Enjoy the energy!

Step 1, involves the sunlight connecting with the panels in order for the panels to then convert the sunlight into electricity. Solar panels contain photovoltaic cells (PV). PV cells take photons (light) and transfer that latent energy into voltage (electricity). PV cells start producing current electricity; they then need the inverter to convert the power generated into usable electricity.

Step 2, is when the inverters come into play. The inverter converts the usable electricity into alternating current, which can be used to power up our homes.

Step 3, alternating current electricity flows to your net meter which then measures the power that is needed and that which has been drawn from the grid. It also measures the excess power that your solar panels have collected from the sun and then sends it back to the grid.

Step 4, once the electricity runs through your net meter, it then adjusts to your home and powers all electrical applications from the television to the tumble dryer!

How Much Do Solar Power Systems Cost?

In recent years solar panel costs in Australia has fallen in price due to cheaper manufacturing costs and there being more competition in the market. Some 66% of homeowners said they paid less than $4000 for their solar power quote. Solar power quotes can range between $1500 and $8000 depending on the number of panels installed. Two solar panels, suitable for one adult household would have a solar panel quote between $1000 and $2000 and eight solar panels suitable for two adult household would cost between $3000 and $5000. As previously mentioned the comparison quotes depends on the size and quality of panels, different solar energy companies Australia will have different pricing.

What is a Solar Hot Water System?

The Australian government is trying to encourage its citizens to switch to solar hot water systems, as statistical figures reveal that heating water is the biggest single source of greenhouse gas emissions in Australian households with the exception of cars.

Solar hot water systems use solar collectors which take energy from the sun and heats the water in your home. The heated water is then stored in an insulated tank for whenever you need it. If the sun is not shining then the hot water system may need a boost. This boost will happen when the temperature of water in the tank drops below the thermostat setting. Once the preset temperature is reached, it will turn itself off automatically. If you need more control over the booster, then a manual booster can be installed which will allow you to adjust time settings to your needs. Solar hot water systems may need frost protection if you live in a colder area where there is the potential of you experiencing significant frost.

It is true that solar hot water systems will cost you more than your average hot water heating system. However, the cost will be paid back as it will save you more money in the long run. The two key advantages are the fact that you will ultimately spend less on heating and you will essentially be saving money, also, you will be helping the environment by reducing greenhouse gas emissions from your home.

How Many Solar Panel Systems Were Installed in 2017?

So, you’re probably thinking this all sounds good but are people actually looking into solar panel comparisons? Yes, they are! Australian households installed a record 3.5 million solar panels. This is doing wonders for the environment in Australia as they are reducing greenhouse gasses big time. In 2017 there was an increase by 41% across all states compared to 2016.

Things to Consider…

There are many things to consider before purchasing a solar hot water system. One key consideration is, do you have a sun capture location in which to put your solar panels? You must make sure you have enough space to position the solar panels, they do not always have to be on the roof. However, that is the best place for them as they are typically in direct sunlight with little potential for shadowing. It is also necessary to have space for a large, hot water cylinder. A dedicated cylinder will need to be installed or added to your existing cylinder with a solar heating coil. Finally, your current boiler must be compatible with solar water heating. You will find that most conventional boilers and cylinder systems are compatible with solar water heating. The only issue, solar water heating system are not compatible with combination (combi) boilers.

How to compare solar systems

There are four different forms of Solar Power Systems.

  • Grid Connect Solar
  • Stand-alone or off-grid Solar Systems
  • Hybrid Solar Systems
  • Portable Solar Systems

Grid Connect Solar

The most common type of solar system is the Grid Connect Solar. As previously mentioned, the energy converted from sunlight is used to power your appliances and excess energy is sent to the grid. Benefits of this system have already been discussed at the beginning of this article, however, there are some drawbacks to this system.

Solar tariffs can vary depending on the location of your home; it can change between different supplier you are with and which country you live in. Another drawback is that during a power-cut or a blackout, grid connect systems will not work due to safety reasons. The grid is then turned back on once the blackout is over. You can compare solar panel deals for Grid Connect Solar on our website.

Stand-Alone/Off-Grid Solar Systems

You might have already guessed but these systems stand-alone and are not connected to the grid. This type of system can usually be found in remote areas where access to a mains power supply is not available. A Stand-Alone system requires backup batteries to store power. This system can be cheaper than a Grid Connect System in remote areas. You can find solar panel price comparison on our website. You can find Stand-Alone solar energy advantages and disadvantages below.

An option for remote areas Most systems require the use of backup batteries that only last 3 years
Can be cheaper than Grid Connected Systems Batteries require large storing spaces such as sheds or spare rooms.
No need to purchase electricity from a retail supplier High maintenance
Stand-Alone systems can power single items only Expensive
More can go wrong due to more components
Requires expert design
Benefits Drawbacks

Hybrid Solar Systems

Hybrid Solar Systems are backed up by two renewable energy sources, usually wind and solar power. However, the Australian market describe the hybrid solar system as a solar powered system that is connected to the mains grid but also has a backup battery to store excess power. Hybrid solar panels comparisons can be found on our website. You can find hybrid solar panels advantages and disadvantages below.

Benefits Drawbacks
Electricity is still available during power cuts Expensive
Retailers will buy back your excess power High maintenance
Hybrid allows users to enjoy both aspects of the systems Complex
Requires expert/specialist design

Portable Solar Systems

Portable solar systems are usually used for powering appliances to do with farming, fishing and camping for example. This system is designed to be mobile and be taken on the road and wherever you need to be and require electrical power. The portable solar system allows energy to be provided in remote locations where access to electrical mains is unavailable. You can compare solar panel prices for portable solar systems on our website and the advantages and disadvantages of solar energy from portable solar systems below.

Benefits Drawbacks
Transportable Limited Range
Lightweight/Robust Not suited for houses
Designed for a specific purpose

The Grid Connect Solar is the most beneficial and reliable choice for most people. That being said it depends on the access you have to mains and what the purpose of the system is for. If you want it on the go and are constantly moving then the Portable Solar System could be a better option.
