Solar Panel Installer FAQs

what is solar thermal?

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.

Do solar panels require maintenance?

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.

how many solar panels and batteries to power a house?

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.

How much energy does a solar panel produce?

How much energy a solar panel produces depends on its manufacturer and exposure to the sun. A good-quality solar panel typically has a power output of about 300 watts per hour, but this can vary from about 240 to 360 watts. How much energy your solar panel will produce per day depends on how many hours of unshaded daylight it’s exposed to.

Here’s an idea of how much energy you could expect a large commercial solar panel installation to produce in a year.

Solar panel system size, No. of solar panels, Annual electricity output

11kW, 44, 9,350kW

20kW, 80, 17,000kW

30kW, 120, 25,500kW

40kW, 160, 34,000kW

50kW, 200, 42,500kW

How many solar thermal panels do I need?
Generally, the amount of solar thermal panels you need depends on the number of people living in your home. Experts say that as a rule of thumb you’ll need 1m2 of solar panels for each adult living in your home. So if you live in a 4-person household, you can expect an MCS-registered installer to recommend you a 4m2 system. However, if you have any obstructions near your home that could increase shade on your panels, you might be encouraged to go up to nearer 2m2 per person. You want to make sure that your panels can produce enough hot water for your home as you’ll rely less on your back-up form of heating, which might be a gas boiler or electric immersion heater. Maximise the free energy from the sun and you could save up to £60 per year if you have a gas boiler, £70 if you have an immersion heater or £100 if you have an LPG boiler. Of course, you’ll also need to make sure you’ve got enough roof space for the amount of solar thermal panels that you want, but your installer will be able to advise you on the best course of action.
how does solar thermal generate electricity?

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.

How much do solar panels cost?
The cost of solar panels has reduced significantly over the years. While a system may have cost you up to £20,000 in the early days, that’s not the case anymore. So how much do solar panels cost today? The cost of an average 4kW system on an average home will set you back between £4,500-6,500. But pair that with the savings on your electricity bills and payments that you can receive from the Smart Export Guarantee (SEG), the net cost could be much less. The SEG is a payment from your energy supplier for any electricity that you don’t use and send back to the grid. Each energy supplier can set their own rate, but it must be above zero at all times. This replaces the Feed-in Tariff Scheme (FITs) which used to pay solar panel owners per kW of electricity they generated as well as that which they sent back to the grid. This was a much more lucrative scheme which saw homeowners earn back the cost of their system within a few years, but it ended in March 2019. Now, with the SEG and your savings on your electricity bills, you could save up to £330 a year – meaning you could break even within 14 years. Solar panel systems are likely to last up to 25 years, so they’re still well worth investing in. Combine that with the saving of 1.29 tonnes of carbon dioxide every year, and you’ve done your bit for the environment.
can solar thermal be used for central heating?

If you’re thinking about getting a solar thermal system for your home, it’s normal to consider the possibility of using the system for central heating. So is this viable? In this article, you’ll learn how solar thermal panels can be incorporated for heating. Let’s have a closer look!

Heating and hot water systems, on the average, takes up a sizeable part ( up to 70 percent) of our energy bills. Now take a moment to imagine how cool it’ll be to generate your own hot water for free without having to depend on any supplier which in turn significantly reduces your energy bills. Well, this is exactly the work of central heating systems that are powered by solar. That’s super cool, right? Well, let’s have a look at how this works.

While solar panels generates electricity, solar thermal panels produces heat for hot water production. However, what’s important is the fact that they both make use of the sun’s natural energy to provide us with a free and renewable energy we can use in our homes. Here’s how it works.

Solar thermal panels directed at central heating incorporates the sun’s natural energy to heat water in a storage cylinder which is then available for use at home. These solar thermal panels are exposed to the sunlight by fitting them on the roof of the home. Generally, they’ll include tubes that contains liquid whose job is to collect the heat and then transfer it to a hot water cylinder that’s solar compatible in your home. The heat is generated for free and is also renewable. This is help you save lots of money on oil, gas and even electricity which you purchase to power the cylinder.
