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.

If you’re looking to install a solar thermal system in your home, this is usually one of the first concerns several homeowners have. Being fully aware that solar water heating systems are usually more expensive than their counterparts - the conventional water heating systems, the question arises whether or not you’ll be able to save some money from your solar water heating system in the long run. In this article, we aim provide an answer to this important question. Let’s take a closer look!

When it comes to solar thermal systems, the money you’ll be able to save in the long run depends on a wide range of factors. These factor includes:

✓ Your system’s performance.

✓ Your geographical location and solar resource

✓ Your household’s hot water demand

✓ Financing and incentive options that are available.

✓ The cost of fuel that’s being used for your alternative or backup water heating system, if you own one.

✓ The cost of conventional fuels such as oil, electricity or natural gas.

There are several benefits, however, that comes with the installation of a solar water heating system. Since the sun is absolutely free, future fuel shortages and price hikes will have little impact on you. Also, on the average if you decide to fit a solar thermal system your water heating bills is expected to drop about 50 percent to 80 percent. What’s more? The economics are even a lot more attractive when you’re just about to build a new home or refinancing. When you include the price of a solar water system in a 30 year mortgage, it’ll normally amount to very low price per month. Therefore, on a monthly basis you’ll be saving more and paying less.

There are a few factors that will determine whether it’s worth getting a solar battery. They involve how much electricity you use, how often you’re at home and whether you receive any export payments.

To work out whether it’s worth getting a solar battery, you need to work out how much of the electricity you generate you’re using already. If you’re able to run all your appliances during the day while your solar panels generate electricity, then it sounds like you’re already using your electricity well. It might not be worth you getting a solar battery in this case.

However, if you’re not at home for a lot of the day, then you’ll be missing out on the electricity your panels are generating while the sun’s shining. If you install a solar battery system, you can store the electricity that your panels generate in the battery and use it when you get home. This will help you cut your electricity bills even further.

You’ll also need to consider whether you’re getting paid to export your electricity. If you’re on the Feed-in Tariff scheme (FITs) or receive payments from the Smart Export Guarantee (SEG), you’ll get paid for every unit of electricity you export to the National Grid. Before you decide whether it’s worth getting a solar battery, you’ll need to weigh up whether you’d be better off carrying on exporting your unused electricity rather than storing it to use yourself. If you’re unsure, visit the Energy Saving Trust’s website or speak to an MCS-registered installer who will be able to help you work out which is more cost-effective.

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.

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.

Biomass boilers do require some maintenance. Many manufacturers recommend servicing twice a year, although this is often included in the installation cost. Many systems have automatic fuel loading that removes the need to manually load fuel. You will need to remove the ash from the boiler, but this is as easy as emptying a vacuum cleaner.

Are you thinking of installing solar thermal systems in your home or property and wondering exactly how it works to generate electricity? Regardless of your motive, in this article you’ll learn in simple details how solar thermal is how solar thermal doesn't provide electricity for your home.

If you are looking to generate electricity for your home then Solar PV are able to generate electricity simply by absorbing and focusing sunlight in such a way to create a temperature level that’s high enough to generate the much needed electricity. There are two main components that comes with the solar energy collectors of each. These two components include, the reflectors ( mirrors), which works to absorb and concentrate the sunlight onto a receiver. In several types of the solar thermal power systems, a heat transfer fluid is then heated and distributed in the receiver so as to generate steam. Once the steam as been produced, it’s then transported to the turbine where it’s turned into a mechanical energy, which in turn powers the generator to produce electricity.

Solar thermal power or electric systems are usually embedded with a tracking system which keeps the sunlight concentrated on the receiver all day long as the sun changes position in the sky. They also come with a wide array of collectors which works of distribute the heat absorbed to a turbine as well as the generator. A lot of solar thermal power facilities will gave two or more plants with different arrays and generators.

Solar thermal power systems can also have a thermal energy storage system component whose work is to permit the solar collector system to heat an energy storage system during the day while energy storage system’s generated heat is incorporated in the production of electricity at night or during a cloudy weather when there’s not much sunlight.

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.
