Hybrid Solar System – Who doesn’t hate the increasing tariff of grid electricity? With the increasing tariff and awareness of global warming, people nowadays are switching to solar power. Solar power not only offers you the opportunity to reduce carbon footprint but to also become energy sufficient by taking the electricity production and consumption into your own hands.
One of the biggest decisions to make while installing a solar system is to choose between the on-grid, off-grid and hybrid solar system. While on one hand, where an on-grid solar system doesn’t allow storing excess electricity and the off-grid system doesn’t allow having the guaranteed supply of grid, hybrid solar system overcomes the limitations of both the solar systems and allows you to enjoy the benefits of both.
So, if you ever thought that why you aren’t able to get all the electricity from your solar system, store it and bid adieu to local power companies, then “Hybrid Solar System” is the perfect solution for you. Let’s take a deeper look at the hybrid solar system.
Hybrid Solar System – To Enjoy the Best of Both Worlds
The hybrid solar system is a blend of grid-connected and storage-ready batteries that offers constant electricity supply, all time. You receive the guaranteed electricity supply of the grid with the capability to store the excess solar power in a battery for later use. You also have the option to switch to your own battery, when the grid goes down.
As compared to the off-grid system, the hybrid solar system is less expensive and doesn’t require diesel back-up too. Though it is way more expensive than the standard on-grid system, the benefits of solar batteries outshine the initial expense.
From providing backup power to reducing maximum demand, hybrid solar systems can be configured to meet several situations, including
- Rural off-grid systems
- Power quality filtering and correction
- Backup power supply
- Load shaving to reduce maximum demand
- Load shifting to maximise the time of use metering
Why Do You Need To Store Solar Energy In A Battery?
Many local power companies have reduced the solar FIT (Feed In Tariff). This has reduced the efficiency of the grid-tied solar systems as most of the people work during the day and not able to utilise the generated solar electricity. This leads them to feed the generated electricity into the grid for very little credit.
While a hybrid solar system stores the excess produced energy and allows you to use it in the evening when the rate of grid electricity is usually at the peak rate. It works in a similar manner as an off-grid power system, but the required battery capacity is far less. You need a battery enough to cover peak consumption, usually 8 hours or less.
Why Should You Consider Installing Hybrid Solar Systems Instead of Regular Solar Systems?
1. Keep The Electricity Flowing When The Grid Goes Down
When the failure of the grid is detected, standard grid-tied solar systems shut down immediately. This is done to protect any workers repairing the wires outside your place. The workers can be injured with your solar system sending the current while they’re still working on the electricity cables in your street.
While on the other hand, a properly designed hybrid solar system safely disconnects your connection from the grid during the power outage and turns your home into a little mini-grid. This allows you to use the electricity during black-outs when your neighborhoods are still waiting for the power to come back.
2. Get The Energy Bill Down
When you opt for the hybrid solar system, you can store excess solar-generated electricity and use it as required later. By storing the excess electricity instead of feeding it back into the grid helps you to minimize your reliance on your utility electricity provider.
After all, why feed the generated solar electricity into the grid for half or less the price you pay to your electricity provider. Simply, by initially investing in the installation of a battery, you can get your energy bill even to $0.
3. Overcome Export Limits Imposed By Local Electricity Network
Many local electricity providers have strict restrictions on maximum solar system sizes. They claim that their grid cannot handle the additional electricity that larger solar systems provider. This often forces homeowners to install a much smaller solar power system than they need to offset their energy bills.
The hybrid solar system is the best way to rescue this situation. All you need is to install a smart inverter that works with your battery and you are good to go. You can configure these hybrid inverters to have the highest export rate. For instance, if your solar system produces 10kW electricity, you can export 2kW to the grid and store rest 8kW electricity into your batteries for later use. This is a win-win situation for everyone.
Can Batteries Be Added To Regular Grid-Tied Solar Systems?
Yes, you absolutely can!
With the advent of technology, home battery storage systems are becoming more and more affordable. This has lead most of the homeowners in Brisbane to consider adding batteries to their existing solar system.
This allows homeowners to store their solar generated electricity and use it as back-ups instead of exporting it to the grid and perhaps getting a low FIT.
To make your existing solar system compatible with batteries, it is highly recommended to have a solar system of at least 6.6kW. This enables you to produce enough electricity to charge your batteries when the weather is overcast and in winter.
If your present solar system is under 6.6kW in size, consider adding more solar panels to it. And, for this, you need to increase the size of the inverter too. It is wise to oversize your solar panel array to your inverter. You can always take the advice of your installer on whether your inverter needs to be upgraded based on your battery size, household energy usage and your local climate.
One of the easiest and effective ways to retrofit batteries to your present solar system is – “AC coupling”. Within this technique, you don’t have to touch the existing solar wiring and simply connect the battery into your home’s existing AC circuit.
The Economics of Hybrid solar Systems
With technology advancement and in the highly competitive market, hybrid solar systems are rapidly becoming cheaper than using grid electricity with standard retail tariffs. Rather than investing in an on-grid or off-grid solar system, investment in hybrid solar system delivers great savings and returns.
There are added benefits of having electricity from a stable and clean source and will also keep providing consistent electricity, even in the event of a blackout. Listed below are some of the economic benefits of hybrid solar systems.
- Savings on energy bills
- Credit on power bill for the electricity you supply to the grid
- Increase the value of your property
- Several advantages from reduced emissions and lower carbon footprint
