This will vary depending on which part of Australia you live in, your current hot water system and hot water consumption, the model of Solahart you install, the orientation and inclination of the system's collectors and of course your fuel tariff. Maximum financial savings off your hot water bill are achievable when replacing an electric water heater on continuous tariff.
Water heating accounts for around 25% of the average household’s energy usage. Getting your hot water free from the sun not only saves energy, it also saves the greenhouse gas emissions that would have been produced in the generation of that energy. By replacing an electric storage water heater with a Solahart you can reduce greenhouse gas emissions by up to 3 and 3.4 tonnes a year*, the equivalent of taking a small car off the road. In fact solar water heaters are so good for the environment that STC's (formerly Renewable Energy Certificates) and some government incentives exist to make it easier to get into solar hot water.
Each STC represents the equivalent of one megawatt hour of electricity generation from an accredited renewable energy source. For solar water heaters each STC represents the displacement by solar energy of one megawatt hour of electricity generation from a non-renewable energy source.
The installation of a solar or heat pump water heater in your property may be eligible for the creation of STC's. The financial benefit from assigning your right to create STC's for your solar or heat pump water heater installation can be used to reduce the purchase price of your new Solahart.
The number of STC's which may be created varies with the model of solar or heat pump water heater and the region in which the unit is installed. The value of an STC is not fixed and varies from ‘time to time’.
Some states still offer rebates but with differing eligibility requirements. To find out if you are eligible, please contact us.
Financial payback will vary depending on your circumstances, but with the available incentives plus the ongoing energy savings you can begin to recoup your additional investment straight away when you remain connected to the same fuel tariff. After you recover your initial investment, the savings are yours to spend on yourself and your family, year after year.
Providing the system is in stock, we are generally able to perform the changeover within a few days. If your current hot water system breaks down, to take away the inconvenience of cold showers, Solahart can have you back in hot water within 24 hours, in most instances, with a temporary system, while you wait for your installation. Once the actual installation is started, it is usually completed in one day.
A solar hot water system uses the visible and infrared radiation from the sun to directly heat water. A solar power system uses the visible radiation from the sun and converts it into electricity for use in the home or to be fed into the electricity grid.
Solar water heating is normally the first step. Getting your hot water free from the sun will dramatically reduce your energy needs. Once you have reduced your energy usage, the next step is to install solar power. The less energy you need, the less power you will need to produce from your solar modules.
Solar power systems use photovoltaic (PV) cells to produce electricity. When sunlight hits a solar power system, direct current (DC) electricity is produced. This is converted into 240V alternative current (AC) using an inverter. This electricity can be used immediately within the home or fed into the National Electricity Grid (grid).
The National Electricity Grid is the network of wires that delivers electricity from generators to homes and businesses around Australia. When you install a solar power system you become a generator of clean renewable energy.
An inverter is an electronic device that converts the DC power generated by the modules into AC power at the correct voltage for supply to the grid. It also provides equipment protection and safety features.
Electricity generated by a solar power system is used to offset or replace the power that would normally be purchased from your electricity supplier - thereby reducing your power bills and saving money. This solar generated energy also avoids the harmful pollution caused by generating electricity from the burning of fossil fuels.
The savings on offer are very attractive and will go on for years. The amount you save will depend on your household's current electricity usage, the size of the solar system being installed, orientation and inclination of the modules and the feed-in-tariff offered by your electricity supplier. Your local Solahart consultant will assess these factors and give you an estimate of your savings.
Yes, because the inverter will only produce power when it is connected to the grid supply.
A grid connected solar power system does not store energy. When you generate more power than you need, you supply the extra power into the grid. At times when you need more energy than you are producing, you draw the extra you need from the grid.
Our smallest system requires a roof area of around 11 square metres. This will generate around 30% of the average family's energy needs each year. The more powerful the system, the more solar modules and roof space are needed.
Solar power systems work best on an unshaded north-facing roof. It is also possible to install a solar power system on an east or west facing roof, however this will reduce the performance of the system.
This depends on your roof space and the size of your inverter. If you have sufficient roof space and additional capacity in the inverter you could increase the size of your system. If room permits you could add a second system to your roof.
Solar power systems only produce power when they are exposed to sunlight, they do not produce electricity at night. At night you will not generate electricity from your solar modules - you will use electricity from the electricity grid. The performance of the solar system is affected by cloud. When there is not enough light to produce electricity, you will use electricity from the grid, as you do now.
In the event of a black out, your solar power system will stop producing electricity. This safety measure is mandatory and has been put in place to protect anyone working on the blacked-out grid system. As soon as the grid is back online, your solar system will restart automatically.
STCs are the government's commitment to renewable energy. STC's are created when you install and commission qualifying solar hot water, solar/wind power systems or residential solar power systems. Each STC represents 1 MWh (Megawatt hour) of energy produced. The number of STCs you are eligible for varies depending on the size of the system you install and your location.
STC's have a market value (which may vary over time) and are tradeable; they can be sold, or used to get a discount or cash. Solahart offers and upfront discount on the price of a solar power system in return for the STCs.
The number of STCs created for a system will depend on the amount of renewable energy the system generates. In areas with higher solar radiation there is greater opportunity to generate electrical power and so the number of STCs is greater.
The electricity providers may offer feed-in tariffs for the electricity your solar power system generates and feeds back into the grid.
A feed-in tariff is the rate paid by the electrical utility for each kilowatt-hour of electricity your solar power system feeds into the grid.
The feed-in tariff schemes are set by the state governments and vary between the states (either Gross or Net). A Gross feed-in tariff pays for all of the electricity generated by the solar power system. The owner then buys back the electricity that is needed. A Net feed-in tariff pays the owner only for surplus electricity produced by the solar power system.
Payback periods may vary depending on the applicable feed-in tariff, householder electricity usage profile, size and cost of the PV system installed. Your Solahart dealer will be able to provide an estimate of payback period for your system.
Solahart modules are manufactured to high quality standards and will require minimal maintenance for many years, other than keeping the surface of the modules clean.
Solar modules are one of the most reliable energy conversion systems.
