Today I will discuss battery storage of solar. The most significant features and technical parameters might be difficult to discern when comparing quotations for various solar battery systems. Home energy storage is so new that you are unlikely to know anybody who has used a battery and can provide comments. There are strict reliability and safety requirements for batteries sold and installed in Australia.
Solar battery technology’s price is falling, and it’s feasible that solar batteries may be included in all solar energy systems in the near future. It’s a good idea to contact a number of well-known battery storage contractors if you want to pair your solar panels with storage and get the best possible price for your solar system.
Is solar battery storage worth it?
Recently, if you’ve been researching solar panel systems, the word “solar batteries” has most likely come up. The energy generated by solar panels and battery storage of solar is an excellent investment since it may be used as a source of emergency power if needed. No matter how popular battery-powered systems become, a lot of people have no idea how they really function.
With solar batteries, you can save the energy produced by your solar panels and then utilize them later. With a “hybrid solar system,” you may receive a number of advantages, such as reliable backup power and independence from your utility, by combining your solar panels with solar batteries.
How Solar batteries can be stored?
Weatherproofing and freezing temperature protection are required for battery storage. Batteries that need less care (such as sealed batteries) may be kept in the home. While most solar energy systems make use of flooded batteries, which produce hydrogen gas and should be kept in a well-ventilated room away from the living space, certain systems make use of dry batteries.
Step-1. A garage, a well-protected shed, or an enclosed porch are all good options. It is recommended that you keep your batteries in a battery box that is durable and well-ventilated. If required, this may be made more insulating. Winter preparation is an excellent time to complete the periodic maintenance that most batteries need in order to achieve their maximum durability and performance during their service life. You will need to check with the manufacturer for precise instructions on how to use your particular battery.
Step-2. You need to be aware of this step. Most batteries, on the other hand, will benefit from cleaning the terminals and ensuring that the connections are secure. It is possible to clean and coat lead acid battery terminals with high-temperature grease after they have corroded using a combination of baking soda and water (be careful to wear gloves).
Step-3. If your batteries have been flooded, you will also need to check the water level in the batteries. It is recommended that you do this task once per month or two; if you are not in the habit of doing so, now would be a good time to create reminders on your calendar. If the water level is low, fill it up as much as you can without overfilling it. Only distilled water should be used in your batteries.
Can solar batteries be installed outside?
The installation of certain house batteries may be done either inside or outside, depending on the system that you choose. For this reason, many homeowners opt to install a battery system in their garage, which provides some shelter from the outdoors. The Tesla Powerwall 2 and several other versions may be put either indoors or outdoors because of the mild environment in Australia, which prevents excessive temperatures from occurring.
You would need to make certain that a battery system located outdoors is maintained free of major material such as leaves and snow accumulations, and that it is protected from possible floods. While the majority of people use home battery systems to help them make the most of the solar energy produced by their PV system at home.
It is feasible to utilize certain home battery systems in houses that do not have a solar array installed. Not all products will be able to do this function, but some, such as the Tesla Powerwall 2, may be configured to do so.
How can solar batteries protect from outside?
Winter isn’t only hard on us; it may also be hard on our battery systems, which might cause them to fail. This is due to the fact that cold weather affects battery capacity and may potentially significantly limit battery longevity. Fortunately, by following a few simple measures, you can improve the performance, capacity, and longevity of your batteries all year long.
CHOOSE LONG-LASTING BATTERIES
When it comes to battery performance and longevity, engineering and construction processes are key factors to consider. However, even if two batteries have the same specs, changes in materials or design may have a significant impact on how well they function in extreme situations.
For example, larger lead plates and more active material allow for more chemical reactions to take place, which results in longer service life. Advanced assembly techniques, such as automated manufacturing, may increase the longevity and quality of a product while decreasing the amount of maintenance required.
KEEP YOUR BATTERIES WARM AND INSULATED
Batteries perform best at temperatures ranging from 50°F to 85°F. Furthermore, when the temperature drops below 32°F (0°C), their capacity decreases. While the capacity loss caused by cold is only transitory, it might lower your storage capacity at the worst possible moment — when solar output is down and system loads are often at their maximum.
It is recommended that batteries be stored in insulated enclosures by Crown’s experts and professional installers. The presence of sufficient thermal mass, the absence of direct sunshine, and, in the case of flooded batteries, proper ventilation in a shed, garage, or other structure are all essential. It’s a good idea to provide insulation to batteries that are being used outdoors for anything other than their intended purpose or to store them inside when not in use.
SIZE YOUR SYSTEM FOR NO MORE THAN 50% DISCHARGE DEPTH.
The presence of a safe energy buffer – extra power that can be used when electrical needs are greater, batteries are running at a reduced capacity, or production is lower – is critical no matter what battery technology you are using.
Every battery technology has a distinct Depth of Discharge that it can safely withstand. Aim for a DOD of no more than 50% to ensure that your equipment or residence continues to operate. If your system is consistently subjected to severe discharges in excess of 50%, you should consider installing extra batteries to extend battery life.
PREVENTATIVE MAINTENANCE ON A REGULAR BASIS
Every battery, including AGM and lithium-ion, needs a regular visual check in order to operate at peak performance. The following are essential battery maintenance procedures to ensure that your battery performs at its best:
Examination by means of the naked eye
- An examination of the specific gravity
- examining the voltage drop across an open circuit and the use of electricity
Battery storage of solar is an excellent investment since it may be used as a source of emergency power if needed. As a result, you become more self-sufficient while simultaneously decreasing your energy costs. In certain cases, you may even save money on your electric bill as a result of using battery power instead of grid electricity.
In contrast, solar battery solutions are not without their own set of disadvantages and benefits. Even if your utility provider offers net metering as part of its service, adding a solar battery may not be the best way to reduce your power cost.
