Solar panels are a one of the best ways of reducing your homes electricity bills, as well as earning money. Many homes and businesses in the UK choose to install a Solar Thermal System to reduce their heating bills with a special government incentive called the RHI (Renewable Heat Incentive). Your business can create its own energy with commercial Solar PV, lowering the costs of any business bills whilst helping the environment. RSPI, short for Renewable Solar Photovoltaic Installation is a family run business which specializes in helping home owners get the most of our their renewable energy requirements at the best possible price.
Interest in battery storage for solar energy among Brisbane residents has skyrocketed in the last year, with Solar Choice’s website statistics showing a 100% increase in storage-related traffic among Brisbane residence since January.
Just as with solar panels, investing in a battery bank for your home is a serious decision.
Brisbane households fall into one of three categories when it comes to home energy storage. If you’re in category 1, it does not make economic sense for you to install battery storage (although you may wish to install batteries for emotional or environmental reasons).
If you are in category 3, then you have a significant amount of flexibility in selecting your solar panels and battery bank. Example: A household in Brisbane that uses about 10kWh of electricity on average per day would like to reduce their reliance on the electricity grid by as much as possible within a budget of $10,000 (roughly the amount that the average household says they would be willing to spend).
Keep in mind that this may not pan out favourably as an investment, however, as indicative calculations show that the payback period on this system could well over 10 years. Are you feeling well-informed enough about energy storage to start shopping around – or do you just want to have a look?

The size of the solar panel system you get will depend on the size of the roof of your house. This will vary from installer to installer, depending on their own charges and also on the make, model and type of panels used. By using the same calculations mentioned above, we can see that a larger system generating 4kW will cost from around ?10,000 to ?14,000. It stands to reason that the size of the installation will directly affect the amount of energy you can generate.
So it makes sense that over time you will generate more revenue from a larger system as well as generating more power. As you can see, it may well be worth investing in such an installation if you have the roof space to do so. Just came across this website and ive been impressed with the articles and blogs, really enjoyed reading this some good answers here and helped me out alot thanks for sharing! This 3kW size grid-connect solar kits include solar panels, string inverter, and the racking system for roof mount. The kWh generated monthly by these systems is great for eliminating the impact of a hot tub or running the air conditioner. Racking and Attachments – Industry leading IronRidge racking mounts the solar panels to your roof. Our kits use industry leading solar panels, inverters, and racking systems specifically selected and combined to make do-it-yourself installation possible.
A homeowner who has wired an AC outlet and is comfortable working on their roof can install our Solar kit. The installation of a solar system, even from a complete kit is considered above the average homeowner’s skill set and should not be taken upon lightly. If self-installation is not for you, we can help you find a local solar contractor to help you with the process.
Some state & local governments as well as some utilities are also offering financial incentives to homeowners.
Investing in solar on your roof provides 6%-13% return on investment, better than most other investments today. By going solar you’ll be supporting local jobs and helping America become more energy independent. By going solar you’ll be reducing our dependence on fossil fuels and help clean up the environment for future generations.
We have already published an article on this topic with the title Serial Connections in Solar Panels. Apart from a simple battery, using an additional protector on the solar panels will protect both our system and the panels.
The above formula that we stated mathematically could be applied in a practical sense, but the solar cells have to be identical. The system is ready for use; you can use it by taking the mutual output connected at the top. You can connect more solar panels using similar methods but you have to be cautious of the current. The thing to do in this point is to connect 2 or 4 panels in series and increase the voltage to 24V and 48V.
With the connection above the voltage value triples while current value doubles, becoming 3V and 2A. With the connection above the current value is four times higher and the voltage value is twice as high. Q: I have 3 solar panels that are of different brands but they have the same voltage value, can I shunt them?


A: If you connect this kind of a circuit, the system would work on the generator whose voltage is lower and the remainder will be lost through heat loss. Q: What kind of a problem would arise if a panel in the parallel circuit solar panels fails?
A: It will not have a negative effect on the whole system but the system's total current value would decrease by as much as the failed panel. I have 5 panels differing wattages, All same voltages with controller into 12 volt batteries. If your system voltage is 24V your charge controller input must be 24 – 36V for best effciency.
If you connect the panels with 2 X serial + 4 x Parallel the Imp = 22A the voltage drop values reduced to %2 – 3. I know if the cables are too thin, the loss is great; but if the cables are more and necessary thick, is that an advantage?? Hi, i purchased a solar kit- (2) 50w photovoltaic panells 30ah controller,100ah battery and 400w inverter for my food truck and have 6-60w daylight bulbs wich are supouse to consume 13w each,26w lcd and a small 120v 0.1A casio register.
We have 8 120 watt panel voltage calculation— as it is a 12 volt system, it would make about 5 to 7 amps equal to watts? Question should we use a seperate refrigerator 240 volt inverter power circuit on seperate battery bank seperate inverter? Could you show me a diagram of how to connect 6 modules in a string and 4 strings in parallel. Hi I have 3 100w and one 50w how can I connect them to have 12v and how much amps i will have. Could you please tell me how many solar panels i need to connect to get 17000 kW output from solar panel,what is the mppt charge controller and battery rating i need to design? I have two 10 watts Solar Panels and I wish to power 4 DC-bulbs of 5 watts each and also to be charging mobile or cell phones.
Now i wish to combine the two system in to single system with 2 KW inverter at 48V DC nominal. I have 16 solar panels of 225 watts 24volts and i want to connect them to 12 200Ah battries in a 24volts battery bank system. Should i put breakers between panels and charge control and another breaker between charge control and battery another breaker between battery and inverter?! I have 11 solar panels, 7 of which have a 12V 150 W peak output and 4 with a 36V 240 w peak output. Sir I have 6 solar panel of 100 watt and 2battries 150 mah sir iwant to connect it.sir please tell me how thisone connect toteather. Please am tryin to charge a 120volts battery bank using a 2.2kilowatt of panel connected in series running for 8 metres distance. Hi, I have two solar panels (150w), i need to know if it working correct, so what is maximum Voltage should give in control (12V)?? You install Solar Thermal on any roof type including commercial property, hotels, leisure centres and agricultural buildings. What are the benefits of installing batteries for Brisbane residents, and what are the key questions to ask for households considering a home energy storage system? It’s therefore important that you fully understand how energy storage works and how it would apply to your specific circumstances. Depending on which category you are in, you’ll want to think differently about how to best approach energy storage. Batteries might be a good option for you if you are sending a lot of solar energy back into the grid. This home could be sending around 8kWh of solar to the grid on the average day, and would want to capture as much of this as possible using batteries. With the battery storage, this home would utilise close to all of the electricity produced by the 3kW solar array. Assuming they install a 2kW solar system for about $3,000 (about the average price, according to our own figures from November 2015), they’ll have $7,000 left to spend on storage. For this home, it may be prudent to hold off on investing in batteries until prices have come down. Solar Choice recently launched Australia’s first Battery Storage Comparison service, which will allow you to compare installer offerings at a glance in an apples-to-apples format.
Typically speaking a small terraced property will have less room for solar panels to be installed than a larger detached property. But if you have a larger property that has available roof space of 21 square metres or above, you could consider a 3kW or 4kW system. Obviously, the more efficient the panels are the more energy they will be able to generate and the more money you will save and earn in the future. For example a 4kW system will be likely to generate twice the amount of energy as a 2kW system.
When you have solar panels installed you will start generating your own power from the moment the installation is completed. In fact although a larger solar PV panel system will cost you more upfront, you will be able to earn back the cost of the installation more quickly than you would with a 1kW or 2kW system. The scheme compels energy suppliers to pay you for the electricity you produce via PV solar panels - and sees you paid extra for any electricity you export back to the grid. So if your queries aren't answered in other areas of the site, you'll most likely find what you're looking for here - in our Solar FAQ.
Refer to your electric utility bill to find the actual kWh used per month and compare it to how much power this 3kW PV system can generate.
These are complete PV power systems that can work for a home or business, with everything you need to get the system up and running.
Each task is rather simple, but you will be working at heights, on a angle, probably in the heat of the bright sun, working with power tools, hoisting large expensive pieces of glass up ladders and across a roof peppered with racking and wiring.


In serial connections the voltage increases, whereas in parallel circuits the current value increases.
The main reason for that is that the solar panels not only generate electricity by virtue of its chemical construction, but it also consumes and exerts power.
First of all, suppose that the voltage of each solar panel generates is (V) and the current is (I), and we have two, identical solar panel cells.
If you think that efficiency is not that important, you can also use a series connection for the 6V panels and shunt them to a 12V panel. First of all, the current would measure at least 400A which would cause an increasing loss on the conveying cables meaning you would need to use thicker cables.
If the panels faced different directions it would receive sunlight at different angles and this would cause extreme loss levels.
If you have solar panels with different power and structure and you do not know how to connect them you can use this guide. I am asking because in Tristar’s manual it is written that 12 Volt battery bank may be charged even with 48 V nominal off-grid solar arrays. Yes you must increase the solar array voltage with 2 X Serial + 4 X Parallel for less voltage drops. I start my load in very sunny day from 10am and at 5pm everything shuts off and the controller is set for 9hr. Voltage are still same which is good but i am getting the same amps too isnt it amps should be high both panel work i checked them one by one both are giving 19 volt and 7.28 amps single or connected.
I request you to provide the technical combination for the same and also i request you to provide whether we need to provide any diodes in the combination network. A 150vdc 96amps mppt charge controller, 24 pieces 100watts panel and 6 pieces 130watts mono panels. But when my load is just about 1.5A , solar system support it just for 2 to 3 hours after that it is going to shut down what should be the issue please support and reply me. Your decision about whether or not to have a storage system installed will also depend on how well you know the market – most importantly, the range of prices and product options. This means that the electricity that your panels produce is worth more to you as a credit on your energy bill than if you were to consume it yourself at home. Assuming 90% round-trip storage efficiency and 80% maximum recommended depth of discharge (DoD), roughly 9kWh of battery capacity would help the household meet this goal.
For most homes, the most prudent economic decision will be to install a solar PV system just large enough to meet their daytime needs, perhaps with a small battery bank to capture some of the excess electricity produced by that system. At present, this service is available only to new solar-plus-storage customers – not to those with existing systems (but this will soon change). The ideal place for panels to be installed is on a south facing portion of roof, so this will also determine how many panels you can have. Some people would rather invest more in the best panels on the market today, so they can earn more from them in future.
But of course it does depend on the amount of roof space you have that is ideally situated for a solar installation. If you’re willing to give it a try, it can be a rewarding experience both in saving you a lot of money and of giving you a great sense of accomplishment.
This means that the solar cells of a parallel circuit have the same voltage but a higher current. For this reason, by using both parallel and series circuits, you can increase both voltage and current simultaneously. The 2V and 8A results for this connection can be obtained, but as mentioned before a high current is not necessary. For this reason you should use 20 – 30 mm section cables so that the circuit would remain safe.
The greater the difference between the Vmp and battery voltage, the greater the current boost.
If you charge the batteries under high currents the life of battery will be reduce and your operational cost will be increase.
Homes receiving this generous incentive (which closed to new applicants in 2012) will maximise their savings by sending as much of their solar electricity into the grid as possible; there is therefore no financial incentive to keep it stored in batteries for consumption at home.
The yellow line is solar system power output, while the purple line is battery state of charge – aligned with right axis.
What is important about the parallel circuit is that both of the solar panels have the same voltage output value; if this wasn't the case then there could be issues with the parallel circuit.
The idea was to increase input voltage to 70.32 V by connecting two panels in serial and then four pairs in parallel. The input power will be the same – 1480 W and accordingly max output current will stay the same.
Wouldn’t this wiring configuration create inefficiencies due to the unbalanced parallel circuit voltages? Because at this stage, each panel aray is connected for 48v, but something damaged my batteries, because it doe not last. Because Tristar’s max current is 60 A so I set max current threshold programmably to 60 A.
But I never discharge my battery below 50% therefore usually charging current not exceeds 50 A in case of clear sky in the summer time.
