Are there any solar hot water rebates still available?
Unfortunately there are no longer any rebates available from either the Federal or Queensland State Governments for the installation of Solar Hot Water sytems. The only concession available now when installing Solar Hot water systems are the Renewable Energy Certificates (REC’s).
What is an REC?
Each solar hot water system receives a set amount of REC’s. You can sell them to electricity retailers who use them to comply with the Mandatory Renewable Energy Target. The number of REC’s you will receive depends on the system you purchase. More efficient systems normally attract a higher number of REC’s. Prices for REC’s vary daily but as an example if the Solar Hot Water system you purchase attracts 30 REC’s and the current price of each REC is $24.00 you will receive a $720.00 point of sale discount.
How Much Will I save on Electricity?
How much you save on electricity depends on the amount of hot water you use and how efficient your solar hot water system produces hot water. According to the Department of Environment and Water Resources, it is between $300-$700 each year that you save on electricity. This equates to a saving of $25-$58 per month.
Depending on where you live, your solar hot water system contributes most of your hot water needs for free. State governments have undertaken research to determine what percentage of hot water we can get for free from the sun – in Queensland that figure has been determined as 85% whereas NSW is determined to be between 65-80%. Just that in itself should be enough to seriously consider switching to energy effiicient, clean technology solar hot water.
How long does a solar hot water system last?
No one can give an exact estimate of how long a solar water heater lasts. Just the same as for any other technical appliance.
However, here is what the Evironmental Protection Agency says about solar water heater life spans:
” A solar hot water system normally lasts 15 to 20 years, which is double the life of an electric system. They are a well-proven product and have experienced substantial development over the past decade, with newer models expected to last even longer”
According to Sue Roaf, Author of ‘The Ecohouse 2 – A Design Guide’ (Arichitectural Press, 2003) writes:
” A good liquid solar collector should have a life expectancy of 20-30 years. Most of the collectors built since 1980 are manufactured with materials that should give a 30-50 year lifespan”
What follows is that the tank might need replacement before the collectors. As they are two separate pieces only connected by plumbing, it is quite simple to do that.
