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.

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.

How Much To Install Solar Panels And Battery?

Are you thinking about installing solar panels and battery in your home and wondering how much the installation is going to cost? Well, you’re not alone. This is one of the most commonly asked questions in the solar world, but unfortunately a precise answer can not be provided. This is mainly due to the fact that solar panel systems come in varying sizes which is the main influencing factor that determines how much electricity that can be generated. In other words, the larger the system, the more the electricity that’ll be produced to your home’s benefit.

Generally, for a solar system size of 1kW, the average cost of the solar panel ranges between £1800 to £1850, 2kW is between £3600 to £3700, solar panel size of 3kW ranges between £5500 to £5600 and finally, 4kW is between £6000 to £6050. For example, with the aforementioned prices in mind, the cost of solar panels for a standard 3 bedroom house will range between £5520 to £6040 as the high electricity demands will need the installation of 3 to 4kW solar system size.

Meanwhile the installation cost of solar batteries is also dependent on a number of influencing factors like the size as well as the make of the battery. Generally, you can expect to spend within the range of £500 to £2000 to install your batteries depending on aforementioned factors. In the event whereby you’ll be retrofitting, you might also need to include an additional cost of £1000 for an inverter. However, it’s important to note that there are only quite a few hybrid systems which are able to combine a battery storage with an inverter.

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.

Solar cells , also referred to as photovoltaic cells (PV), absorbs energy from the sun and converts it to generate electricity. This, however, should not be confused with photovoltaic thermal cells or PVT which operates to generate heat for water in homes. Solar cells are linked electrically and also carefully organized into a large frame which is popularly called solar panels. Generally, solar cells are produced or made of silicon semi conductors which works to absorb sunlight and then turn it into electricity for use at a home. A solar panel comprises of either 60 or 72 solar cells which are electrically interconnected in series and parallel and also positioned in between glass and plastic which is then framed.

At present, solar panels incorporated for residential or domestic purposes only possesses the capacity to make use of only about 20 percent of the sunlight they’re able to absorb and convert it to electricity - also called solar efficiency. Available in the market are also a wide range of solar cell available for both industrial and commercial purposes. This type of solar panels have an efficiency rating of about 40 percent which will also automatically make them more costly than the domestic types.

One great thing about the solar industry is the fact that it keeps improving in such a way that raises both its efficiency as well as overall quality. And with further research and development, this is expected to even increase as the years go by. What’s more? As these aspects keep rising, it’s also expected that the solar panels price should be on a decrease. That way, they’ll become available to a wider range of individuals who’ll also like to save money on electricity bills and go greener.

Are you interested in fitting a ground source heat hump in your home? If yes, then one of the thing you’d probably like to know is whether or not the heat pump is noisy. In this article, we seek to provide you with necessary information that’ll solve these mystery.

One thing you should when it comes to heating products is that they all make some noise. However, they’re usually a lot quieter when compared to fossil fuel heating systems. Generally, a ground source heat pump can reach within the range of 40 to 60 decibels depending on the manufacturer of the product as well as it’s installation.

The noise levels of heat pumps are a major concern for several homeowners. However, the fact is when the system becomes a nuisance or becomes noisy, that is always a sign of poor planning as well as poor quality installation. This is because heat pumps, in general, are not usually noisy.

In ground source heat pumps, volume isn’t quite associated due to the lack of a fan unit. However, it remains a very common question for homeowners who intends to install a ground source heat pump to ask whether or not the type of heat pump is noisy. Just like any other heating product, there are components in the ground source heat pump that produces some noise but this is always not as much as that of an air source heat pump. This is due to the fact that the heat coming from the ground is more consistent, hence the compressor’s power capacity wouldn’t be as high. What’s more? This type of heat pump doesn’t also work at full throttle which also plays a key role in its low noise level.

Biomass boilers can be designed to work with other kinds of heating. The most common of these is solar thermal. This is a popular renewable energy pairing. Solar thermal heating will meet your hot water needs during the summer while a biomass boiler can operate as a backup during the winter when solar thermal panels do not perform as well.
