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.

Unlike the photovoltaic (PV) power which works to turn a part of the electromagnetic radiation of the sun directly to electrons and electricity, a solar thermal can simply be referred to as the absorption of the sun’s heat for human use. As a result, the solar thermal has a wider range of uses than the PV does in several ways. This is due to the fact that the sun’s heat can be absorbed and transported via a medium and the stored energy incorporated for several great purposes such as to heat water, to heat and cool a home or living space, to prepare a meal as well as to generate electricity. All these functions are useful for both residential and commercial spaces.

There are generally three different ranges of solar thermal energy that are being used which includes the low temperature ( for heating, cooling as well as ventilation), the mid temperature ( used for preparing meals, heating hot water and the likes) as well as the high temperature ( used for generating electricity). To focus more on generating electricity, there are a wide array of ways through which the sun’s heat can be directed at creating electricity via a heat exchanger which operates to super heat water or inert gas to power an electricity- generating plant or to produce electricity via a Stirling engine.

In order to increase their output or make them more efficient, evacuated glass tubes are used to encircle the tubes which in turn helps them to collect more heat energy while also protecting them from re-radiating the heat energy absorbed. The trough are normal positioned north to south as well as to keep tabs on the travels of the sun throughout the day.

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.

How Long Do Solar Panels Last?

As an alternative form of energy, solar panels are becoming increasingly popular all thanks to a wide range of benefits it provides. It does not produce any emission which makes it greener and more environmentally friendly, it requires little maintenance and are less likely to break down, they also come with warranty that are always quite long mainly because of the life expectancy of the average solar panel amongst many other advantages. Therefore, if you’re considering to purchase and install new solar panels within your home, you’d also probably want to know the time period in which they’re expected to last. In this article, we aim to help you answer this question so you can make an informed decision going ahead.

As a result of the rising energy bills as well as the desire to be greener, solar panels are becoming increasingly popular by the day in the UK. The most recent models of solar panels in the market possesses an expected lifespan of 40 to 50 years as well as warranties that keeps them protected for a minimum of half of that period. These warranties also serves as a guarantee to the solar panel’s level of performance over the first half of their lifespan. Several warranties will guarantee that the performance will not go below 80 percent before the warranty lapses. And even more importantly, some solar panels are crafted in such a way that they wouldn’t drop below 80 percent performance level throughout their lives.

However, in order to derive maximum benefits from your solar panels for a long period, there’s a need to ensure they’re properly maintained at least once a year throughout their lifespan.

You shouldn’t need to maintain your solar panels much at all as long as there’s nothing piled up on top of the panels that could block out the sun. They are installed at an angle, so when it rains the water runs off them and gives them a clean. However, if this doesn’t quite cut it, you can spray them with a hose a few times a year.

There are two different types: flat plate, where lots of thin tubes carry water through a flat absorber panel, and evacuated tube, where vacuum glass tubes capture the sun’s energy directly. There is little difference in performance between the two but evacuated tube panels do more obviously extrude from the roof.

Solar panels are a great source of energy with numerous benefits that comes with it. However, the main thing that puts off most homeowners or potential buyers is the fact that the equipment are usually very expensive. So if you’re planning to purchase solar panels to be installed in your home, then you’d probably want to know if it’s actually worth the investment or otherwise. In this article, we aim to give you a good insight into how solar panels works and if its a viable investment.

Generally, the length of time it will take for your solar panels to payback and whether you’ll be able to make money from them will be based on the following factors:

✓ The solar panel PV system’s cost.

✓ The amount of the generated electricity that you’re able to use.

✓ Whether as well as the amount you’re paid to the electricity you’re able to generate and export.

To know whether your solar panels are truly worth it, then a higher initial cost to fit the system will require to be settled with the amount you’re able to save through the use of the renewable electricity it produces, rather than making purchases from your electricity company. In other words, the more renewable energy you’re able to use, the more savings you make. If you’re registered for the FIT and paid per kWh of electricity produced, for 50 percent of that, which is assumed to be exported to the grid. Therefore, if you’re able to use more than 50 percent, you’ll be able to benefit from the investment.

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.
