Solar hot water, heat from the sun is captured through collectors installed on the roof and transferred into the water flowing through them. The now hot water is then stored for use later.
Solar power converts the suns light into electricity. The amount of electricity that it can generate depends on the number of panels and size of the inverter. The excess energy can be sold back into the grid, and when the sun isn't shinning, it can be bought from the grid.
Solar Hot Water is usually the first step to reduce your energy needs. Once your energy has been reduced the next step is to install solar power. The less energy you need, the less energy you'll to generate from your solar power system, which means you can sell the excess to the grid.
A solar power system use the photovoltaic (PV) cells to produce electricity. When sunlight hits your solar panels, direct current (DC) electricity is produced. Using an inverter, the DC power is converted into 240V alternating current (AC). Once this process has occurred, your solar energy can be used in the home or fed into the grid.
The National Electricity Grid is a network of wires around around Australia to help generate electricity to homes and businesses. When you switch to solar power you are generating green renewable energy.
Solar power helps reduce your energy costs so that you can limit or don't have to purchase all electricity from the grid. The generated energy is also green and therefore reduces the harmful pollution caused by the burning of fossil fuels.
How much you will save depends on the size of the system, orientation and inclination of the modules and the feed-in tariff that is offered by the electricity supplier. You will need to contact us to get an estimate of the savings that you could receive from your solar system.
No, your system by itself will send the excess energy you are not using to the grid. However, there are a number of new solutions becoming available to allow you to store your solar energy to use later. You'll need to contact us to find out which solution would work best for your home and business.
Your system does not operate when direct sunlight doesn't hit the modules. This means that your system does not operate at night and therefore you will being using energy that is supplied from the grid. The performance of the system may be affected by the cloud, if there is not enough sunlight to generate electricity you will need to use energy from the grid.
Solahart systems are manufactured to the highest quality and therefore require minimal maintenance for years. It is recommended to has a service every 5 years and to get your solar panels cleaned often to ensure that your system is working at full potential.
Each payback period differs depending on your circumstances, this includes your feed in tariff, how much electricity you use and the size of your system. For information regarding your own payback period, please contact us.
Solahart offers a conditional 10 year warranty on 255W series panels and conditional 5 year warranty on Solahart inverters. For full warranty details refer to the Owners Guide and Installation Instructions.
Yes you can. The technology is not available currently to retrofit the storage system to existing inverters and as such it would require the replacement of your existing inverter as well as the addition of the Powerwall and the necessary components to accompany the Powerwall. You may also need an upgrade to the size of your existing array, as the solar power system needs to be able to produce enough energy so that you can both use the power during the day, and store the power for night time use. It’s definitely possible though, so if you want a quote,give us a call!!!
Unfortunately at the moment, if you are one of those lucky enough to be on the Solar Bonus Scheme and receiving 44c for your existing solar power system, installing any battery storage system will cause you to forfeit your generous feed in tariff and as such is not recommended at this stage.

What on earth does it do?
The Tempering Valve (TPV) is a safety device designed to control the delivery temperature to you taps. It does not change the temperature of the water in your storage tank. The TPV restricts the delivery temperature to around 40-55°C by blending cold water with the hot water to this safer temperature. Tempering valves blend hot and cold water to deliver mixed water at a constant temperature. They incorporate a temperature sensitive element which expands and contracts depending on the temperature of the water flowing across it. This action of the element in turn moves a piston which shuttles between the hot and cold ports. In doing so the valve maintains an essentially constant outlet temperature, and thus reduces the risk of scalding accidents.
A TPV is required by law; hence we include this installation whenever we complete a full installation of a new solar hot water system. Solar hot water systems can reach water temperatures of up to 99°C; therefore the need for a safety device is more vital when installing a solar hot water system. The tempering valve works mechanically.
The water is colder than my old hot water system, why?
Your old hot water system most likely did not have a tempering valve installed, therefore you may have been getting around 65-70°C water delivery to your taps. With a tempering valve installed the delivery temperature is now anywhere from 40-55°C.
Can the valve be made hotter?
If you feel that the water is too cold, the TPV may require adjustment. We have found that some TPV’s self adjust down over time and require resetting. If this is the case, please contact our office to arrange a service call to inspect the valve. But please keep in mind that the temperature is still limited to that range of approximately 40-55°C.
Heating water equates to around 25% of an average household energy bill. Not only do you save money on your power bill you are helping the environment from the harmful gas emissions that would have been used to heat your water.
Your savings will depend on your situation, this includes the orientation of your roof, the size of the system and how much hot water your household uses, to find out more about how much you can save please contact us.
The Streamline Split System solar water heaters allow you to enjoy the benefits of solar hot water, without the tank on the roof. These systems have low profile collectors on the roof, and the tank on the ground. You might also consider a Solahart Heat Pump which extracts heat from the air, without solar collectors at all.
An electric or gas heater is there for emergencies when there are the dark days, colder days or raining days. Selecting the right system for your family or business will ensure the minimal use of the booster.
Please be aware that this is only a general guide, your installation may be different.
There are 2 ways that you can use it.
The booster can be left on all the time. The thermostat in the Solahart will only use that power if required. The switch only allows the power to be made available to the thermostat operation.
Play the guessing game. You can stretch out you savings a little more by playing around with the switch, such as turning it off when you go away, or if you have evening showers you may shut it off at night to stop it boosting overnight to let the sun do its job the next morning. But this can leave you at risk of running out of hot water.
What does the light mean and when should it be on?
The light, if on, merely indicates that power is available which is particularly handy if you are on off-peak as these times vary. It does NOT mean that the solar is using that power. The thermostat in the unit will regulate if it actually uses any of that power.
Why do I need to use it more in winter?
During the winter period the water coming into the solar is a lot colder, the days are a lot shorter and people tend to have longer showers, therefore the sun may not keep up with your needs. This is the time of year you tend to use the booster a bit. Please keep in mind that it is still heating up from the sun, the booster just tops it up that bit extra that is required.
Why is the water colder the next morning, isn’t the tank insulated enough?
The Solahart tanks are insulated quite well, however overnight the hot layer and cold layer in your tank will begin to blend so if you use a lot of hot water in the evening and you do not have the booster on overnight you will notice a change in the temperature.
The light never comes on and I run out of hot water.
Check that the fuse has not been tripped and that the circuit breaker in the meter box is in the on position and that the booster switch is in the on position, if they are all fine then there may be a problem with your supply, please call your local energy supplier to check your meter.
I am on Off-Peak, how does this work.
Off peak power is a cheaper tariff rate that most electric hot water heaters are connected to. When off peak switches on varies quite a bit. Off Peak tariff 31 (Night Rate Super Economy) usually is on overnight weekdays and most of the weekend. Off Peak tariff 33 (Controlled Supply Economy) gives you the addition of a couple of hours extra around lunch time. The light on the booster will only go on when off peak is in effect.
