How Do Solar Panels And Batteries Work Together?

With solar panel system rapidly becoming an ubiquitous phenomenon within the modern society, several homeowners in the UK are just coming to terms with the numerous benefits offered by the system. The solar power’s popularity has even led to the rise of another renewable technology - solar batteries able to store excess solar power that can be used later. Now several companies such as Tesla are now building solar batteries that can be fitted alongside solar panels for your building. So how exactly do solar panels and batteries work together? Let’s have a look!

Solar panels make use of the sun light to generate electricity and as a result, they can’t function when sunlight is absent - giving a big issue of how to power your house when it’s dark. In the event whereby this occurs, you’re afforded two options which is either to contact energy providers to buy electricity or purchase a battery storage system.

So what’s the function of the battery storage system? Basically when your solar panel provides electricity which is not needed right away, a solar battery will work to convert the DC electricity into AC energy which is going to be stored for later use (when you actually need it). in other words, your solar panels charge the batteries when you do not require the energy they’re generating right away.

As a result, when it’s dark and the solar panels are no longer functioning, your system will tap into the energy that’s already been stored by your battery for later use. This way, you can be totally independent of the National Grid, which implies more savings on your electricity bills.

The bigger the ground source heat pump, the better right? Wrong! And you’ll definitely be sorry to make such a huge mistake. When planning to install a heat pump, determining the size of the ground source heat pump is not as direct and straightforward as many homeowners would think. Here, you’ve got only a small margin for error. When the pump is too small, the heat pump will make use of the backup heater too often and in the event whereby the heat pump is too big, it’s going to short cycle. Both situations are preferably avoided as they’ll both leave you with an expensive and inefficient system.

To get the accurate size of a heat pump, there’s usually the need to hire the services of an expert and licensed heat pump installer who possesses a top notch design calculation software. In reality, the majority of inefficient systems are caused by a lack or poor understanding of the suitable design software.

There are many factors that can influence the calculation of a home’s heat pumps size. These includes

✓ Radiators and underfloor heating sizes

✓ Insulation, property fabric as well as heat loss

✓ The number of rooms in the property

✓ The types of rooms and their uses.

✓ The desired indoor temperature for varying rooms

✓ Seasonal temperature fluctuations.

Generally, a bigger house will require a bigger ground source heat pump. With an eye on the age of the property, heat loss as well as the types of the rooms, a house of about 100 square metre can require up to 4kW ground source heat pump. And for a house that’s about 200 square metre, the ground source heat pump also doubles to 8kW.

Like every other systems in your home, solar hot water systems will require periodic inspections as well as a regular maintenance in order to keep it running as efficiently as it should. Not only that, the various components will also require either repair or replacement from time to time. It’ll also be proactive to take the necessary precautions so as to prevent worrying issues like corrosion, scaling or freezing.

Is it a task you can handle on your own? Well, there are some inspections and maintenance activities you should be able to handle on your own, however, you’ll also require a qualified technician to carry out the more technical or complicated tasks. You should also take note that it may actually be more cost effective to have some systems replaced, shut off or removed completely than having it repaired. Here are some of the essential inspections that should be carried out on solar system components. They include:

✓ Collector soiling. Periodic cleaning of your collectors is important especially in dry and dusty climates.

✓ Plumbing, ductwork and wire connections. Check the pipe connections for fluid leaks. Examine duct connections and seals. Also make sure that all wire connections are tight.

✓ Roof penetrations. Flashing and sealant around the roof penetration should be checked to see that it’s in a good shape.

✓ Collector shading. Check for shading of the collectors on annual basis as this may greatly affect their performance.

✓ Support structures. Examine all bolts and nuts which connects the support structures to the collectors for tightness.

✓ Heat transfer fluids. Anti freeze solutions in liquid solar heating collectors will have to be replaced periodically. And this right here is a task that’s best handled by a licensed technician.

If you’re thinking of adding a solar battery to your home, you might be wondering whether or not it’s going to work in a power cut. If yes, then you’re not alone as this is one of the most common questions asked when it comes to solar batteries. In this post, we aim to provide you with a detailed answer to solve this concern once and for all.

The answer to this question is, it depends. The main reason why your solar batteries will usually not work or provide your home with the much-needed back up power is as a result of the several threats it poses. You should be aware that both your solar panels and battery are connected to the main grid. When a power cut occurs, your engineers will have to operate on the grid. If the solar panels or batteries are in operation at the period there’s a high chance the engineers would be electrocuted by the electricity that’s being produced. As a result of this, solar inverters are usually designed to automatically switch off once a power cut occurs. However, it should also be noted that if your solar battery possesses backup functionality, you’ll be able to make use of your solar energy in the event of a power cut. In other words, what determines if your home battery would work in a power cut is the availability or otherwise of a backup functionality.

Furthermore, you might also wish to know if your solar panels will continue to charge the battery in a power cut. Well, this depends on the type of backup system you possess. There are some more affordable batteries that are designed to automatically release their stored energy upon the detection of a power cut. And this is mostly because the battery inverter is usually smaller than the solar inverter which allows the energy from the solar inverter to the transmitted to the battery - risking an overload. However, if otherwise, then energy can continue to be transmitted to the battery until its fully charged.

Air source heat pumps work by absorbing heat from the outside air and transferring it inside to heat up your property.

An air source heat pump has an outdoor unit containing a refrigerant. This absorbs heat from the air and passes into a compressor, where the temperature is increased. The heat then transfers either into water, which feeds into your wet heating system, or into air, which is dispersed around your property.

Air source heat pumps need electricity to run, but this is to power the compressor rather than directly generate heat.

First and foremost let’s look at the meaning of a ground source heat pump. A ground source heat pump is simply a renewable heating system which happens to absorb the low temperature solar energy stored in the ground or in water with the help of a pipework that’s submerged and converts this energy into a higher temperature through compression. A ground source heating pump is capable of supplying the entire heating and hot water needs of a building throughout a whole year regardless of the season. So how exactly does a ground source heat pump work? Let’s have a look!

In principle, a ground source heating pump makes use of a refrigeration system but in a reverse form as it extracts low temperature heat from one point or location which is the source and transfer a higher temperature heat to another point or location - the sink. The pumps are powered by electricity and the operational principle can also be incorporated at generating both heating and cooling energy.

Knowing fully well heat naturally flows from warmer to cooler places, the ground source heat pump takes advantage of this physics by distributing a cold fluid via ground array pipework either in the ground or in water. It’s able to extract low grade energy from external sources of heat which includes soil, rock, lakes as well as streams.

Once the absorbed energy has been released to the heat pump from the ground or water, the fluid proceeds with its circuit back to the pipework to start its cycle all over again. Some of the benefits of the ground source heat pumps includes low carbon emission and improved air quality, efficient and affordable heating, the use of free heat from the ground and lots more.
