solar power: the basics - battery energy storage system

Because we are not all masters of the sun, we ourselves take the responsibility to do substantial research for you and inject the light into the sun so that you have the basic need --to-

Not just a good one anymore. to-
Solar technology and economic returns have increased significantly in recent years, making it easier to install solar energy into your home or business --
If you know the basics.
Standard Solar Photovoltaic (PV)
Residential installations include not only panels, but also "modules", as well as inverters-
The power controller or "brain" of the system, as well as related shelves and installation systems. Most are grid-connected (
Access to State Grid)
But some have battery storage and some have both.
Solar panels are basically solid.
Passive components of solar power generation systems.
There are all kinds of solar panels on the international market, and now there are many brands in the New Zealand market.
However, not all solar panels are equal. a key factor to consider when investing in solar energy is the quality of the components used.
As a way to help you distinguish between wheat and grain shells, the industry has developed three
Rating system (Tier 1, 2 or 3)
This ranks many panel manufacturers in terms of quality, reliability and history.
First-class manufacturers have also invested a lot in R & D (R&D)
Using highly automated manufacturing technology, it has a history of at least five years in manufacturing solar panels.
In other words, if something goes wrong and you know that you have been safely protected, it is likely that the company will continue to operate in 20 years to fulfill its guarantee.
To make sure that you don't end up getting lemons for the solar system, it's important to make sure that the panels you buy come from reputable Tier 1 manufacturers.
Fortunately, most of the panels in New Zealand are Grade 1 products, or the worst is grade 2 products.
In the world, there are some house fires caused by defective panels.
Also, while the first tier option looks more expensive than the second and third tier, the warranty on the product is only as good as the company behind it.
Some products on the market have long term or extended warranty terms, but when you look closely, the warranty is "underwritten" by a third party.
Therefore, these guarantees are good only when insurance is paid.
If the company from the panel source stops the business for any reason, or stops paying the warranty, you may encounter a claim issue in the event of a product failure.
If the solar panel is the hardware of the solar system, then the "Inverter" is the brain behind it.
The inverter is the most complex electronic part of the system, which basically covers the DC current (DC)
Alternating current generated by solar panels (AC)-
Power supply that can be used in your home.
The inverter also has a built-in protection circuit for controlling the import and export of the power generated by the system.
When purchasing an inverter, ensure high quality is higher than cost.
This is because solar system failures are often due to Inverter failures rather than panel failures.
Micro inverters are becoming more and more common.
Each solar panel has a small inverter that hides power from DC to AC on the panel
Not at one point in the system.
The advantage is that if a panel is obscured, then only the solar production of that panel is affected.
For traditional "string" inverters with lower cost, if a panel is shaded, then the performance of the entire array will be limited to the level of the lowest production panel.
Nevertheless, unless you envision a serious shadow problem, the price premium for a micro inverter is often unnecessary.
If your property is somewhere in the middle
If a partial shadow may appear, an alternative solution can be provided by the optimize panel.
These panels have built-in optimizers that can optimize the output and performance of each panel individually, like a micro inverter, but without changing the current at the panel level.
Solar energy storage (battery)
Technology has not kept up with the pace of solar cell technology, and prices have not declined.
However, with the absorption of solar energy and the continuous surge in electricity prices, the development of costsEffective, long term
Battery technology is the fastest growing segment of the energy market.
Now, the affordable "hybrid" solar system is only a matter of time --
That is, those who have a certain level of battery storage while connecting the grid-

Whether it's at your home or at a power company --
The next step is important.
The process is rather complicated and heavy if you do it yourself, so choose an installer that can provide the terminaltoend solution.
Before you install, you first need the permissions to connect to the local power network (
Application documentation involved, submission of system design details and electrical specifications).
Then you need to have a registered electrician to install.
After that, a certificate of conformity must be inspected and issued by a registered electrical inspector.
You must also apply to your power retailer to replace your existing meter with an meter that can measure the imported meter (
Electricity from power companies)and exported (solar)power.
This new meter installation can take two months and you can only enjoy the cash benefits of the new system once the installation is complete.
It is up to you to decide who will be your electricity supplier.
Currently, Meridian and Mercury Energy are two of the best retailers to offer decent prices for the excess power you produce.
In general, continuous maintenance and monitoring of regular cleaning of panels and annual supplier inspection of the system to ensure the normal operation of the system.
From a performance monitoring point of view, whether you are interested in daily performance or in monthly energy saving, most inverters include simple readings of wireless or Bluetooth monitoring via a laptop or smartphone to indicate the performance of the system.
The level of monitoring depends on you.
The advanced system on the market monitors the use of solar energy and municipal electricity, which is particularly useful in commercial applications. in commercial applications, the system can measure the use through all aspects of property energy consumption, electronic equipment, electrical appliances, etc.
Warranty personnel within the scope of the warranty you need to pay attention to two things.
The first is the manufacturer's product warranty on the panel.
This covers panel manufacturing failures and provides 10-
Product warranty for 12 years.
The second problem involves power production. In general, power production needs to be large-scale within 25 years.
Better panels are usually guaranteed to produce 90% or better in 10 years and 80% or more in 25 years.
It is also useful to find well-known suppliers that provide ongoing maintenance programs.
Long-term consideration if you want to add battery storage to your solar system in the future, considering the cost and convenience benefits of doing so, this is a smart move, whether a micro inverter is actually the best solution to choose is questionable. Why?
Storing solar energy in a battery requires re-powering
Reverse the battery back to DC power supply, which increases unnecessary costs, and multiple reverts reduce overall solar efficiency.
In addition to ensuring that you purchased the first-level system, verify that the installation is done as per regulatory standards.
It is also important to make sure that you purchase a system that meets the right size you require.

Finally, be alert to industry newcomers who may be here today and may leave tomorrow, leaving you with no ongoing support.
Do your homework and don't let the rogue rain on your sunny solar parade.
Solar facts and statistics predict that 43% of New Zealanders will have solar energy in the future.
• 2,000 households in New Zealand currently use solar energy to power their homes.
• Household solar absorption has increased by 15% since 2007.
