How Many Solar Panels And Batteries To Power A House?

Do you wish to know the number of solar panels and batteries sufficient for a house? Well, this is a frequently asked question in the solar world which would be very difficult to provide an accurate answer. This is basically down to the fact that all homes are unique with different sizes as well as amount of daily energy requirements. As a result, the number of solar panels and batteries needed would be unique to the house in question. However, we’ll consider the varying influencing factors that will go a long way to help calculate the number of panels and batteries needed to power a house.

First and foremost, let’s take a look at the solar panels. You’d have to start here by putting into consideration all household appliances that makes use of power in the house to get a good idea of how many that’ll be needed.

• How Many Watts Is Being Used In The House On A Daily Basis?

To determine this, simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• What Is The Number Of The Peak Sunlight Hours At The House’s Location?

Having in mind that the solar panels only work when under direct sunlight, the first step to determine the peak sunlight hours. Once determined, you can then multiply the figure in hours by the house’s hourly energy usage and divide by the solar panel’s wattage.

Overall for a 1500 square foot house, the number of solar panels that’ll be required should fall around 15 to 18.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries that is required to power a house. These factors include the house’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications.

Unlike in houses constructed in the 1960s, where you’d probably need to rewire the entire house unless the wiring is the modern PVCu coated type, majority of houses built in the 1970s would not need to be rewired. Most often than not, what they’ll need is just a consumer unit as well as an earthing upgrade. If you happen to have a consumer unit change, the electrical professional you hire would have to inspect the most parts of the property regardless. With that answered, you may also wish to know just how often a house would need to be rewired.

First and foremost, in order to make sure that your wiring is safe there’s a need to ensure that a periodic inspection is carried out by a fully licensed and qualified electrician every 10 years. Meanwhile for rental properties with tenants, the landlord is required to carry out a periodic inspection at least every 5 years. This will make sure that the electrical works in the property are safe, up to date and suitable for continued usage.

In order to determine whether your house needs to be rewired, there are some signs or indicators you’d have to watch out for. If you notice one or even a combination of the following , then you should get in touch with a registered electrician:

• Discoloured outlets and switches
• Persistent burning smell
• Outlets problems
• Flickering lights
• Tripping circuit breaker or blown fuses
• If you happen to possess aluminium wiring
• If you have continually experienced electrical shocks

It must, however, be said that rewiring a house is a messy and quite disruptive work. It’s also considered to be quite dangerous and recommended to be carried out only by a professional is well trained and experienced when it comes to tackling electrical works.

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.

If you’re thinking about installing a solar thermal system in your house, it’s always important to put into consideration numerous factors before you proceed. While some solar thermal systems are suitable for use at home, there are also some that are suitable for businesses or organizations which normally requires a big amount of hot water like hotels, restaurants, schools, hospitals and many more. You’ll also find some types available in the market that are suitable for communities to satisfy communal hot water demands.

It should, however, be noted that solar thermal systems do not have the capacity to produce all the hot water demand of a house. In the UK, an average household will need an annual water heating of between 3000kWh to 5000kWh. Whereas, a solar thermal system is only able to meet about 40 percent to 60 percent of this demand.

With that in mind, it’s also worth noting that during the summer months when the solar radiation is at its peak and hot water demand is relatively lower when compared to other seasons, a solar thermal system may be able to provide all of your household’s hot water needs. This implies that during this period you may not find the need to operate your boiler at all. However, during winter or colder months, when you have a higher hot water demands in contrary to a lower solar radiation, a solar thermal system will only be able to take care of about 20 percent of your household’s hot water needs. And that ultimately implies that during this period, you’ll need to rely more on a alternative or backup source of heat like gas, coal, electricity, oil or LPG.

If you’re about to acquire an electrical safety certificate, it’s quite normal to be a bit curious about the length of time the certificate is expected to last for. Well, this is also a bit tricky as the duration is determined by your type of property. In this post, we aim to shed more light into this topic in order to give you a detailed insight and help you make informed decisions moving forward.

As earlier stated, the validity of your electrical safety certificate or report is based on the type of property you own. In event whereby you happen to have tenants living in the property, the electrical safety certificate will last for 5 years or with every change of tenancy, depending on whichever comes first. However, in the event whereby you happen to live in your property, the electrical safety certificate is going to remain valid for 10 years. What’s more? For commercial properties, the electrical safety certificate is also valid for only 5 years. Meanwhile for caravans and swimming pools, the electrical safety certificate possesses a shorter lifespan of just 3 year and 1 year respectively.

The suggested length of validity is only the industry standard. And as such, landlords are not under any legal obligation to get their electrical safety certificate updated at the aforementioned times. According to the Landlord and Tenant Act of 1985, landlords are only required to keep the electrical wiring in proper condition at all times. It does not in any form require landlords to get an electrical safety report or certificate.

One of the primary reasons why you need to get an electrical certificate is that you may not be allowed to show legal proof that the wiring and electrical set up in your property was in the best possible condition in the event of an electrical accident. Several insurance companies will not accept your claims if you’re unable to present the electrical safety certificate.

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.

You can find out roughly how old your wiring is by simply looking at it. If the wiring around your fuse box is covered in old-fashioned casing, or is damaged or fraid, it may be over 25 years old and need replacing. This is more common in older properties or houses that have been empty for long periods of time.

When the wiring on your property becomes dated, dangerous or non functional, then rewiring of your house becomes a necessity. If you’re thinking about rewiring your house, one of the first few things you’d have to put into consideration is the cost of completing the project in order to help you set a budget and start to plan. In this post, we seek to provide you with the most accurate cost possible for your project to help you get started as soon as possible.

In general, the average cost to rewire a house can vary from £2000 to about £10,000, which includes the prices for both material and labour. Factors that can have a great influence on the final price includes the type of your property, the quality of the existing wiring as well as the complexity of the installation needed. The most important determinants are probably the type of rewiring task you go for (whether for the whole house or some specific parts ) as well as the size of the house. The qualification of the electrician hired and the labour costs will also influence the final budget required to a great extent. Overall, the average cost of rewiring a house stands at £4000 and it will usually take up to 7 days for a complete rewire to be done. For older properties, you may need completely rewire the property in order to enhance the energy efficiency. However, this may not be required the your home was just recently built.

Being a messy and disruptive task which can also be very dangerous especially when handled by a inexperienced individual, we’d strongly recommend that house rewiring is carried out by a qualified and registered electrician who is well trained to perform this task to perfection.
