24 Hour Solar Power!
Solar power is one of the best inventions I reckon since sliced bread.
Unlike sliced bread its not that easy to understand, you think it would be simple, put some panels on your roof then you have the power you need to run your house?
There are things to consider like all the different types of panels inverters, matching the size system to your appliances and then the cost,what if I move?
is it worth it how long will it before I get my investment back?
If you know someone with solar that doesn’t understand it they always say they wasted their money! Which in some cases it is very true.I am going to tell you my story with solar and how I learnt all about it.
Most of my life I have been a sales trainer so I know all the tricks and I love spending hours sitting down with the solar guys listening to their terrible sales skills and unfortunately mostly lies. I am a person that if its not logical to me I want be involved in it. So after sitting down with lost of solar guys learning about all these different systems, I come to the conclusion its just not worth it. Here are some of my reasons of what didn’t make sense to me.
If the electricity grid is down you don’t have power? Hang on your telling me that can produce my own power on my roof and if the grid power is down my system won’t work because it requires mains power to work?
If one of your panels is shaded your whole system won’t generate power or if one of you panel’s dies? Really you telling me that a bit of shade blocks one of my panels and it stops? Yep no power.
Once the sun goes down your back using the grid system at peak rates!
This is just a few examples that drove my logic side crazy! Reason being My wife and I had spent almost $2000 on a solar panel a couple of batteries and a generator for just in case and travelled around Australia for three months and didn’t require power and lived like Kings and Queens.
After living off solar for three months in the bush It got me thinking that it is so easy to set it up in your car why is it so different to the house, My solar setup in the car worked without 240 volts, it produced power when it was shaded? And when the sun wasn’t there it just ran our two fridges and all all our lights and charged our phones and did everything we wanted and more. And we meet lots of people that had microwaves coffee machines you name it that had it all running off a car in the middle of nowhere!
So you can see why my logic brain was going insane when the sales reps were saying that's not possible to have. If you want a solar set up you have to be connected to the grid. What they were really saying is the systems that they all sell are the ones they make the most money out of and no one really sells the other systems because they are not that profitable.
After over 5 years of research and asking questions about solar I learnt the main reason the mainstream solar systems that are sold these days is they are the most profitable systems not the best systems for our planet and who really cares about the customer and once its on their roof and money has changed hands, Not the sales reps problem. He/She has their commissions and he is off to the next place to do another deal. And after saying this not all solar sales reps have that intention most of them just don’t understand it themselves and fully believe what they are selling is the best thing, they are just not educated enough on it.
I have a friend who is in his 70’s and he worked for PMG (Postmaster General) Which is what most of us know these days as Telstra. His Job was to go around and check the solar setups that they had on the Telecommunications towers in rural parts of Australia. We have had conversations for hours and hours about this and the main question I asked was how often did you change batteries and panels and replace parts for the system? And trust me I grilled him and grilled him on information and most of his working career he just drove around and looked at the towers checked them and moved on to the next one. My Understanding is that some of these systems have been set up 30-50 years ago and still work and have very little issues and they run without any input from the 240 volt grid.
The reason these great systems that were built and designed to last never took off is that they were large and financially expensive so they looked at creating all this new technology that they are trying to sell us these days that seems to be financially cheap up front if compared to the price we are paying for power now, Its just not the best thing for the future of our planet and our people, its good for the economical system and that's about it.
What I always look at when purchasing anything is what is the Embodied Energy of that Item or product. Which in a sentence” is the sum of all the energy required to produce any goods or services” With this is mind it is hard for me to make a commitment to a solar systems knowing that there is a better solution out there and finally some larger companies are starting to invest into the correct technology in my eyes.
Here are some tips on what processes I would recommend to go through before you switch to solar.
First thing is to do an energy audit on your house,buy a watts meter and test all your appliances in your house.
Switch your lighting to Led where possible it normally only takes about 12-18 months to get your financial return on your invest.And if the price of energy is like everything else it is only going to get more expensive as time goes on.
If your are on electric hot water next time your system die’s put in a solar hot water system, They have longer warranties less issues and once installed there is little or no cost to run them.
If possible switch to gas cooking and heating for of water rather than a kettle. Even if it means buying yourself a gas BBQ if Natural gas is not available in your area and doing your cooking and heating water on that, it will not save you a fortune in money, it will allow you to have a smaller battery bank and better for the environment. for every 100 ton of coal burned to make energy from the grid only about 30% at best makes it to your home from losses in the grid system.
Take a good look in your fridges and freezers, yes most people these days have a couple of fridges and freezers that are full lots of unnecessary items. Do you really need to keep all that extra stuff?
Have a look at what you have on standby around your house and what is taking your hard earned money and wasting energy for no reason. After installing a watts meter in our own place I reduced our standby cost per hour from 20 cents per hour to 6 cents, if that saves us 10 hours of standby time per day, 5 in the middle of the day when no one is home and 5 at night when everyone is asleep that has the potential to save us 20-6=14×10=$1.40×365= $511 of potential saving per year.
Read your power bill and learn it and understand it, when is your peak time of day what do you get charged, you could save a couple of hundred dollars per year just by putting the washing machine and dishwasher on after 10pm or before 2pm, most energy companies have a peak charge for any power used between 2pm and 10pm at night.
If you understand what uses energy and when in you house it will make picking the right size solar system easier.
When choosing a solar system the most important thing in my opinion is to get one that has batteries, you can get away with a small battery bank and that will pay for itself in no time, as most of the power we use is between the hours of 3pm and 9 at night and that is why the cost of energy is so expensive at this time of the day as it peak. It does not make sense to sell power to the energy company for less than what they sell it to you for that's unfair in my opinion. This is an extreme example you sell them your power your have made all day for .08 cents per kilowatt and if you are on a peak rate buy it back for up to .48 cents per kilowatt.
Having a small battery bank will allow you to create your own power during the day and store it to use at night in that peak time which is when you will save the most.
Ask for a grid connect switch. What a grid connect switch does is depending on how you have it wired, for example you can have it wired so that when your batteries get down to 70% the system switches over to the grid. This saves your batteries as what kills the batteries is when they get cycled all the time. Cycling is when they get lower than 50% and then they charged again.
You can also have your grid connect switch wired so that certain power points in your house are always connected to the grid and that will help save your batteries. For example common things that people have grid switched is washing machines, microwaves and fridges or maybe you might have some large power tools in the garage so you have some power points there connected to the grid not the battery bank. .
The best panels hands down are Copper indium gallium selenide solar cells . There has been some real advancements in this technology the last few years and the quick answer to why this has not been the technology that most company push is because it requires a larger panel to produce the same amount of power as a Mono or Polycrystalline panel until now.
They have less Embodied energy and better for the environment and now that more mainstream companies are investing in the production of it the costs are coming down. All the big players invested into the other technologies in the factories to produce solar panels and have resisted the change in their production lines due to the cost of redesigning the factory’s production lines. Another decision made for the best decision for the economical system not the planet or the people. If Governments would have made the choice of investing in solar for everyone's homes with a battery back up, we wouldn’t have an energy industries or a very little one, and people wouldn’t be need to work so hard just to earn money to survive.
Do some research on these panels and you will see the reason they are so hard to find and why they are not the Number 1 panel sold in the world. There was a time when something that was the best selling item was the best product in the market and unfortunately these days the best selling products are normally the ones with the best marketing budget and which item the big companies will make the most money out of.
