Three of The Most Popular Batteries in South Africa Used for Solar
Leave a commentLeave a comment

It is no secret that the type of battery used in solar applications have to perform an arduous job and need to meet the demands of heavy cycling, unstable power from the grid as well as irregular full recharging. There are different types of batteries that are used for the various applications and need to meet a broad spectrum of unique requirements. When looking at the different types of batteries for your solar power unit, there will always be a number of factors that need to be taken into consideration.

These usually include cost, cycle life as well as installation and maintenance.

Lead Acid Batteries
Lead acid batteries are often incorporated in renewable energy and is reliably used in off-the-grid solar energy applications; a battery that has been used for solar energy, spanning decades.
Lead acid batteries are typically deep cycle and cost almost half the price of lithium-ion batteries.

Lithium-ion Batteries
Lithium-ion batteries are perhaps the most commonly used in storing technology, no matter the kind of application. These include three types – they are pouch batteries (tablets and smartphones), cylindrical batteries – used for power tools and prismatic,used in electric vehicles.

Flow Batteries
These include the Redox Flow Battery which are fast emerging as an alternative storage option.
The vanadium redox flow battery – also referred to as the VRFB is perhaps the fastest-emerging and technologically-advanced type of battery used in solar applications.
With so many options and different types of batteries to choose from for your solar, ensure you select the right one for your needs.

Solar Thermal Solutions for Energy Savings
Leave a commentLeave a comment

The cost of electricity is exponential – and keeping the environment at home or at work pleasant to work in, plus ensuring that water is heated at all times could impact hugely on your utility bills.

In many instances energy saving solutions could prove to be a costly exercise and is very often not affordable by the man-in-the-street.

Perhaps one of the smartest solutions and most effective energy options is the use of solar energy for and the installation of solar thermal solutions for all those energy needs and requirements.

Heating up buildings and water could prove to be a massive source of energy consumption and hugely expensive – by installing solar panels and solar thermal solutions for heating will assist in saving energy and reducing enormous electricity bills.

About your solar thermal solutions:

Using solar thermal heating solutions is a wonderful resolution to heating water and keeping the environment warm at an affordable cost. This system captures the heat from the rays of the sun and uses it for heating water. The solar panels that are placed on the roof absorb the heat and will heat up the solution panels; in return, the solutions will be pumped into the cylinder to heat the water. By incorporating solar thermal solutions you will be able to fill most of your hot water requirements. Furthermore, your energy bills will be reduced dramatically through the installation and use of solar and solar thermal solutions.

BatteryHow it works
If You Wonder How Batteries Work

For those that have always wondered how solar and batteries work in conjunction with each other, there is a simple explanation.

How batteries work:

Solar panels charge batteries.

Solar batteries work by the conversion of the AC energy that is produced in the solar panels and is stored in the form of DC power in batteries to be used at a later stage.

BATDC31-500x500
GP12120-500width
CSB 12V17-500x500

In some instances, though, solar batteries have their own inverter and therefore are able to incorporate integrated energy conversions. Larger solar systems will always require a battery that has a bigger capacity for storage of DC power. When solar batteries are installed as part of a solar system, excess solar electricity for the home will be stored – this is instead of being sent right back to the grid of the power utility. For those that have solar panels that produce a surplus of solar energy, the excess energy will be used to recharged the battery. That means as and when the solar panels are no longer producing electricity, the surplus stored power will now be drawn from this surplus for cloudy days or night-time use. Electricity is only sent back to the grid when the battery is fully charged and you will only draw power from the grid when the battery is flat. Solar systems that have an excess solar storage will be able to store surplus solar power on-site for later use when the sun goes down and can also offer a short period of backup power when the power goes down. The above is a brief synopsis on how batteries work.
