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.

The more you’re at home during the day, the more you can save on your electricity bill, since solar panels generate electricity during the day. The Feed-in Tariff scheme (FITs) ended in March 2019, but the new Smart Export Guarantee (SEG) pays you, via your energy supplier, for the electricity you export back to the grid. With the savings involved in generating your own electricity and SEG payments, you can expect to save up to £390 per year on your electricity bill.

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.

Whether installing an air source heat pump will help you save money depends on your property, how long you expect to live there, and the type of heat pump you get.

Air source heat pumps are initially quite expensive to install. However, if you get an air-to-water air source heat pump, you’re eligible for money from the Renewable Heat Incentive [https://www.energysavingtrust.org.uk/scotland/grants-loans/renewables/renewable-heat-incentive] (RHI). This is a UK government scheme that gives you quarterly cash payments over seven years if you install an eligible renewable heating technology (air-to-air air source heat pumps aren’t included).

All this means that if you have long-term plans to stay in your property, then an air-to-water air source heat pump can be a great way to save money on your heating bills. However, if you’re planning on moving out of your property relatively soon, or are a considering an air-to-air air source heat pump, it may not be the best financial option for you.

It’s important to remember that air source heat pumps are at their most efficient when installed in very well insulated properties. If your property’s not very energy efficient, you may find that a heat pump won’t help you save money.

So do you wish to take advantage of the heat generated by the ground to warm up your home by getting a ground source heating pump? If yes, then you’d also probably be wondering how much a ground source heat pump is going to cost so you can set a budget and start planning.

Installing and running ground source heat pump can cost between the range of £600 to £700 to run on an annual basis, meanwhile it can cost you within a range of £13,000 to £19,000 to have installed. However, you should take note that these prices can be by varying influencing factors such as the size of the installation as well as any other extra work that may needed to complete the job.

When it comes to estimating the time it takes to recover the initial cost of the system via energy savings, nothing is certain as this can be very hard to determine or predict. The main reason for this is due to the fact that it’s dependent on the efficiency of your heating system, the type of system you’re replacing ( whether or not you qualify for Renewable Heat Incentive -RHI payments ), the efficiency of your home’s insulation, how efficiently the system’s controls are being used and how the heat generated from the ground source heat pump would be put to use. However, to figure out how much you’ll save, the type of fuel replacing is perhaps the most essential. For a four bedroom detached house, you can save between a range of £1,200 to £1,300 for a LPG fuel replaced, £1,400 to £1,500 for an electricity fuel replaced, £600 to £700 for an oil fuel replaced and finally, £200 to £300 for a solid fuel replaced.

Air source heat pumps are a type of heating system that you can use to warm the air in your property. They’re a semi-renewable energy generator as, although they use electricity, they extract and use renewable heat from the air.

There are two main types of air source heat pump – air-to-water, and air-to-air. Air-to-water heat pumps are the most popular, and are best used to heat water that supplies underfloor heating systems or large radiators. Air-to-air pumps heat air, which is then dispersed round your property using fans.

Do you want a low carbon way of heating your home? Then, getting an air source heat pump is the way to go! What they do is pretty simple - they absorb the potential thermal energy present in the outside air and transmit it directly to the home or property where it’s going to be compressed and the heat transferred with the help of a number of coils. In other words, it functions by extracting heat from a cooler place and then uses it to raise the temperature inside a home or property. Being very similar to air conditioning units, the amount of heat they’re going to produce for your home or property will be dependent on the size you install. Therefore, the bigger the heat pump, the more the heat that’ll be generated.

Air source heat pumps have two main types which includes air to air and air to water. Air-to-water heat pumps works by absorbing heat from the outside air, then relays it directly into your home or property through the help of fans. In order to move the heat around your home, you’ll need a warm air circulation system. This type of air source heat pump are not eligible for the government’s Renewable Heat Incentive Payment as they can’t generate hot water. What’s more? They can function in reverse during the hot summer months.

Air-to-water heat pumps, on the other hand, operates by extracting heat from the outside air and transmitting it into the wet central heating system. Due to the fact that they’re able to generate heat that’s cooler than the one generated by a conventional gas or oil boiler, they happen to be a better fit for larger radiators or water underfloor heating.

If you’re thinking about installing a solar system in your home or property, this is probably one of the things you’d like to know before making a purchase decision. Well, you’ve come to the right place! In this post, we’re going to give you a good insight into this to help you make the best informed decision possible moving forward. Let’s take a look!

First and foremost, it must be stated that providing a short and accurate answer to this question is nearly impossible as the amount of time a solar panel will last after dark is influenced by a number of factors. These factors include the size of your solar system, the battery size as well as your power usage. As you would have imagined, batteries are charged when there is excess energy that’s being produced by your solar system but it’s not being incorporated to power your home or property. More often than not, this occurs during the sunlight’s peak periods from about 10am to 2pm.

The time it’ll take for your battery to charge is influenced by the size of your solar system in Kilowatts, the size of your battery as well as the rate in which your system is being used. Your battery can be charged in a day or two, of course unless it’s an over-sized battery for your system.

When the sun sets and your solar panels can no longer directly run your appliances via electricity generation, the battery then kicks in. You will use about 1 to 2 kW’s of power if you’re watching TV, using the oven as well as lights internet etc. in other words, even a small solar panel battery will last all night. However, the same doesn’t apply if you’re having a party with running floodlights, three fridges and air conditioner as the battery will drain a lot faster.

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.
