Most domestic solar thermal panels do not need planning permission and are covered by permitted development rights. There are restrictions on the size and location of these systems. If you live in a conservation area or listed building, or want to install a very large solar thermal system, check with your local authority to see if you will need planning permission.

How Many Solar Panels And Batteries Do I Need?

Are you presently considering adding a solar system to your home? With several homeowners in the UK using solar now, many more are realizing the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your home but do not know where to start, you’ve come to the right place.

Here, we’ll help you calculate the number of solar panels and batteries you’ll need to power your home. Starting from the panels, you can begin by taken into account everything that makes use of power in your home to get a good idea of how many you’ll need.

• Firstly, you’ll have to determine the number of watts you use. 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.

• Secondly, you have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

Generally for a 1500 square foot house, you might need around 15 to 18 solar panels to cover the house’s electricity.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house. These factors include your home’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications. Once done, you’ll be able to calculate the number of batteries required by your home.

The importance of selecting the right size battery for your home simply cannot be overemphasized. A lot of home and property owners are facing this challenge and understandably so. Selecting the right battery size for your needs depend on a number of factors which includes your motive for adding a battery, your electricity usage, your budget as well as your panel array size, be it new or existing. In this post, we’re going to take you through some of these factors to help you determine the right battery size for your home or property. Let’s take a look!

• Your motive for getting a battery. While most people purchase a battery to wipe out their need to purchase electricity from the grid with the hope of making some savings, others add a battery so as to enjoy backup power. There are also some who just needs it to power their home with solar energy. It’ll not be economical to size a battery to effectively take you off the grid, but if your motive is to make savings, then you’ll should expect to purchase some electricity from the grid during the year.
• Electricity usage. The average household uses about 16kWh of electricity on a daily basis. During the daylight hours, most of these household will use a third of their electricity when the solar panels are still generating electricity, while the remaining two third are purchased from the grid. In other words, you’ll require a minimum of 10kWh battery capacity if you were to use a battery to power the electricity you purchase from the grid.

For a typical British household, you’ll most likely need a 5kWh solar power system which normally generates about 17 to 21 kWh on a daily basis depending on your location in the UK.

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.

Tesla’s top-of-the-range battery storage system is still one of the most expensive on the market. It has a huge 13.5kWh usable capacity and can even keep you up and running during a power cut. But how long does a Tesla Powerwall battery last? And does this mean it’s worth investing in one?

The Tesla Powerwall 2.0 comes with a 10-year warranty. But Tesla says that it should last way beyond this – at least 5 years longer. The standard warranty says that it should work at 70% capacity for the full 10 years – so if it loses more than 30% of its storage capacity within that time, it should still be covered.

While the Tesla Powerwall does last a long time, it has a large capacity that most average households won’t require, and it’s a costly option. After installation, the Powerwall 2.0 will set you back between £6,500 and £9,000, so ideally you want it to last past its 10-year warranty.

Before you splash out, consider the size of the solar panel system you want to install or you already have. Will it generate enough electricity to make it worth storing in the Powerwall? If not, are you expecting to upgrade your solar panels to a larger system in the future? If you are, then it might be worth investing in a Powerwall. It might also be better to wait until you come to upgrade your solar panels – the solar battery price trend is going the same way as solar panels, so they will probably continue to decrease in price as more people adopt the technology.

Can You Replace A Gas Boiler With An Electric Boiler?

In the UK, there are about 22 million households that are heated with the use of a gas boiler. However, do not assume that they’re the best type of boiler to install. The fact is, if your house isn’t connected to the main gas supply, the best option is for you to install an electric boiler rather than a gas boiler. So is it possible to replace a gas boiler with an electric boiler? The simple answer is yes. Both heating system options work in varying ways and also with a different impact on the environment.

The gas boiler is able to generate heat with the help of a gas burner. A heat exchanger is linked to the burner and heats the water available in its chamber. The hot water is then supplied to the heating circuit.

However, the thing is that natural gas can actually be more affordable when compared to using electricity to operate your boiler, but they have a negative impact on the environment. This is because gas boilers make use of an odourless, colourless and poisonous gas - carbon monoxide.

Meanwhile electric boilers are powered by electrical energy, hence, no carbon monoxide leak risks. Instead of using gas to heat up water, electric boilers distribute energy to heating elements which, in turn, heats up the water. So thinking about what’s best for the environment, you’d go for electric boilers. However, they’re more costly and are not as efficient as oil boilers.

If you reside in a smaller house that’s not connected to the main gas supply, then you might want to consider installing an electric boiler. However, if you live in a larger house, an electric boiler may not be the best option as they’re mostly designed to generate little quantity of hot water.

The cost to charge an electric car in the UK varies between home, work and public charging.

For a typical electric car with a 60kWh battery and ~200 mile range:

• Charging at home: Costs about £9.20 for a full charge. *
• Charging at work: Many employers will install workplace charging points and typically offer free access throughout the day.
• Charging at public locations: Public chargepoints at supermarkets or car parks are often free to use for the duration of your stay.
• Rapid charging: Rapid charging points are normally found at motorway service stations and typically cost £6.50 for a 30 min, ~100 mile charge.

Charging an electric car at home costs about £9.20 for a full charge* and is the most convenient and cost-effective way to keep your car fully charged. Most drivers will charge their electric car overnight, waking up to a full battery every morning.

Average domestic electricity rate in the whole of the UK is about 17p per kWh.

Fully charging a 60kWh electric car will cost between £9.00 and £9.90 (depending on where you live) and give you about 200 miles of range.

* Costs calculated at 17p/kWh based on usable battery is ~54kWh (90%).

How Much Does Pat Testing Cost?

When it comes to Portable Appliance Testing (PAT) there’s no particular rule that determines how much such services can cost. However as a rule of thumb, you should take note that when calling in a professional PAT testing company they’re likely to charge within the range of £1 to £3 per appliance that’s going to be tested. However, if you have quite a number of appliances to be tested, then there’s a good chance that the price per appliance can be reduced to serve as a bulk discount. So the more the appliances to be tested, the better.

There are companies that actually offer a pricing that’s below £1 per item, however companies likely are most definitely going to have a fixed minimum number of appliances that are required to be tested or a fixed minimum fee like 60 portable appliances. It must, however, be noted that pricing can also go beyond PAT Testing as several professional companies will add some additional advantages which is more than just the test of each individual appliance. This kind of pricing can include other services such as a thorough visual inspection, plug rewiring as well as fuse replacements. They can also include stuffs like Pail and Fail labels in the pricing.

Generally, the average price of PAT testing will be based on various influencing factors such as the type of the appliance, setting, number of appliance to be tested as well as other related expenses. What’s more? Most PAT companies will offer a company with a PAT Testing Certificate so as to certify that the company is in total compliance and also remains a safe environment to work.
