GAS VS ELECTRIC HOT WATER

Did you know that an Electric hot water system can make up 30% of your power bill? Few people do, Never the less it is true that the simple luxury of hot water can cost you big, even if it is on the off-peak tariff.

Gas hot water is not much better to be honest, the cost of your hot water won’t be added on your power bill, instead you will be getting a gas bill! And unless you have main gas running to your property you will have to remain on alert ready for when the gas bottle runs out mid shower on a cold winter morning where all of a sudden you find yourself dashing outside in a towel to switch the bottles over (I know this from experience living in my old house).

So solar hot water is the best then?

Not exactly- while solar hot water will indeed save you money on your power bill it is not really the best way to utilise your roof space. Unfortunately, a dedicated solar hot water system can be very costly and will only heat your hot water.

The majority of people choose to have an electric hot water system and a standard solar solar system on their roof that powers their entire home so they can track their usage and also have their bills combined into one -what we like to do is remove the off-peak meters and install a timer in your switchboard that will turn your solar on during the day. This essentially turns your hot water into “Solar Hot Water” with a few added benefits:

• Excess power not being used by your hot water can be utilised elsewhere in your home or even sent back to the grid for a credit on your power bill!
  
• During a cloudy day or periods of poor weather, your hot water will still heat during the day using power from the grid.
  
• Fewer things to go wrong: If you happen to have both solar and solar hot water these are 2 completely separate systems that will each carry their own warranties to worry about.

These timers are a super simple way to ensure that you are utilising your solar in the best possible way. It is literally “Set and Forget” once installed you will have the peace of mind knowing that your hot water is not costing you a cent!

Here at Yuma Energy, we make it no secret that we love our Sungrow Inverters and the reason why is because they are great quality and value for your money, Also rated by electrical engineers for their great performance.

As a company, we have literally installed 1000’s of Sungrow inverters ranging from 5kw’s to 15kw’s for residential customers across QLD and NSW, of those installs the failure rates have been so low it seems impossible, here is a very short list of our Sungrow Failures:

2 x Failures due to Lightning Strikes
1 x DOA (Dead on Arrival)

Unfortunately, there is not much we can do about old Mother Nature and when she decides to strike with around 1 BILLION Volts there is not much that will stand up to that sort of abuse…..

With the 5kw Sungrow (SG5K-D) that was dead on arrival, we will admit there is nothing much more embarrassing than having to say to a customer that their brand new inverter does not work…

Especially after we talk the Sungrow’s up so much! The good news was that because the Sungrow’s are so popular and easy to source we had a replacement delivered to our installers the same afternoon and still managed to get their system up and running before the sun went down.

With the dead inverter, we just took it away from the site and handled the warranty claim ourselves so the customer did not have to.

This brings us to our next point… The Sungrow warranty process was AMAZING, we gave them a quick call and after a brief explanation they arranged a replacement for us and that was the end of it.

To make sure our opinion was actually valid our lead installer (and my business partner) James put the question out to the Solar Professionals group on Facebook to find out what the industry really thinks…

As you can see the post was a hit amongst the solar community with over 214 Comments from seasoned industry pro’s… and here are some of what they said: (Dont worry for full disclosure I will post the whole thread down the bottom so that you may review the entire post)
Note: For privacy reasons, we have had to mark out Surnames and display pictures.

Lets start out with comment number one (Which is actually a +1 for the Fronius inverter)

As you can see Kris is clearly a fan of the Fronius, but all of the points he made still make it a hard justification as to the additional cost of installing a Fronius over a Sungrow, so let’s break his points down a little:
1. Reputation – Of course Fronius does have a large reputation for quality so this point is fair.

2. Generous Ratings for different stringing configurations – This has little to no benefit for 90% of our customers as most installs are fairly straight forward… Yes there is some added flexibility for design with the Fronius but this only benefits a small number of customers.

3. Built-in DC Isolator – As an installer, this is great as it makes our job easier… but there is absolutely 0 benefit of this for our customers. (E.g lets make our customers pay extra to make my job easier)

4. Plugs on the bottom of the inverter – This is a subjective argument, while yes I agree the Fronius inverters do look nice and tidy, I also believe that a Sungrow install done by a Professional Installer can look fantastic too (They look even better if you think about the cost savings while looking at it)

The Fronius supporters comment’s pretty much followed the same tune throughout the thread but what was amazing was the overwhelming support for the humble Sungrow Inverters…

The list could go on but you get the point.

Here at Yuma Energy we always ask our customers “Why are you thinking of getting solar” and the answer is always the same… “To save money”

And if our customer’s main goal is to save money we can not honestly justify the additional expense of the so-called “Premium Inverters”

So you have just had your new solar system installed, what happens now?

The Run Through:Firstly you want to make sure that you have had a detailed run through with your installer to make sure you understand the basic operation of the system and how to tell if there is a fault that needs investigating. If your installer did not go through this or you have more questions make sure you contact your Solar Consultant. You will also want to make sure that all of the appropriate product manuals have been left with you.

If your system was installed by us you can find all product warranty and user manuals here.

The Meter Change:

Before you can start enjoying the benefits of your new Solar system your current electricity meter may require replacing (In QLD + NSW there is no cost to the customer for this change). If you already had a solar system installed prior to this new install your meter should all ready be updated and good to go, likewise if you already have a digital smart meter installed your electricity will just sync to the meter to start reading solar production.

If your meter does require replacing your solar installers will leave the inverter(s) off to ensure that there are no discrepancies in your electricity bill.

Once the installers leave the site your Solar company will work in the background contacting your electricity supplier and the network operator (Energex for SE QLD) to arrange the replacement of your meter to a new digital smart meter. This process should all happen seamlessly without the need for you to contact anyone yourself, it is, however, a good idea to follow up with your electricity retailer if you have not heard anything within 10 days.

It can take around 2 – 3 weeks for your electricity retailer to replace your meter and they should contact you with a date and time for the install. On the day your new meter is installed the metering provider will require access to your switchboard and will have to keep the power switched off for approximately 1 – 2 hours.

Once the new meter is on you can go out to your inverter and switch it on. If you are unsure on how to turn your inverter on please contact your salesman to arrange a detailed run through.

Congratulations, you can now enjoy your solar power and the savings it provides! For some detailed tips and tricks on how to increase your solar savings more check out our other blog posts.

Getting solar installed is an achievement, and you should be proud to say your house is a solar-powered home, and while your system will save you money without you needing to do anything, there are certainly lots of ways to “Supercharge” the savings your solar panels provide.

Monitoring

The first suggestion I would make to anyone who really wants to make the most of their rooftop solar is monitoring, monitoring your solar usage and consumption is a fantastic way to get a clear picture of where you are doing well in regards to energy usage and where you could do better. The simplest form of monitoring would have to be reading the inbuilt screen on your inverter or using the WIFI app that comes free with many inverters. Reading from the screen or using the built-in apps are ok methods of monitoring however it can make it difficult to get a clear picture of your energy production.

If you had a solar system installed by us you would have likely been told about the monitoring solution we like to offer called “Solar Analytics” this is an awesome tool that allows users to get live data from their house that will tell them exactly where, when and how your power is being generated and used. This information is extremely valuable when it comes to making the most of your solar because you are able to clearly see exactly when power is being generated and when it is being used. Solar Analytics also gives portal access to ourselves so we can keep a watchful eye over your system and make sure that everything is operating as intended.

The Basics:

Because the solar feed-in tariff is no longer 45c per KW solar owners need to switch the way they utilise their solar power. The most productive way to use your solar with today’s feed-in tariff is to use as much electricity as possible while it is being produced, for example, put the washing on a timer to wash/dry while you are work. See below for a list of other saving techniques:

• Install a timer on your hot water system to operate between 8am and 4pm
• Heat / Cool your home in the afternoon
• Change old halogen globes to energy-efficient L.E.D’s
• Set the timer on your pool pump to operate between 8am and 4pm
• Use energy-efficient appliances
• Stagger consumption (Don’t turn all appliances on at once)

Note: If it generates heat it usually uses a lot of power!

Electricity retailers

You most likely shopped around for the best solar installer to suit your needs (if you chose us we are very grateful), just like shopping around for solar installers you should definitely shop around for different energy retailers, we find a lot of our customers are with the same electricity provider they have been with for years and often do not realise that they have been sneakily putting up the prices of electricity without the customer realising.

There is no reward for loyalty when it comes to energy retailers, if you find a better deal ask them to match it or beat it and if they do not come to the party give them the flick.

Here are some important things to look for in an energy retailer:

• Daily Supply Charge: These can make up for a large portion of your electricity bill especially once you have had solar installed. If you are in the SE QLD region you want to look for prices certainly no higher than $1.20 per day.
• Feed-in Tariff (Between 11c & 20c): Your electricity usage habits will determine how important your feed-in tariff will be for you, if you are a family who is home a lot throughout the day then a high feed-in tariff would be less important compared to houses where no-one is home during the day. The reason being is if you are home all day you can use your solar as it is being produced rather than selling it back to the grid.
• Discount’s: Who doesn’t like a good discount? The good news for homeowners and tenants alike is that there are plenty of discounts to be found when searching for the right electricity deal. Some of the best deals I have found come in the way of a “Pay on Time” Discount, these can range from 15 – 30% off! Just make sure they are not making up for the discount by giving less than desirable supply charges, and tariffs.
