Find a Solar Panel Installer you can trust in Abertillery.

Solar energy comes from the sun. Solar panels absorb sunlight, and convert it into electricity. This can be used to power heating systems, lighting and appliances. You can also get solar thermal systems, which use solar energy to warm hot water.

Solar energy is a type of renewable energy, because sunlight is considered to be in unlimited supply.

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.

How long your solar panels will last depends on their age and quality. Most modern solar panels have 20-30 year warranties, but this doesn’t mean that they’ll stop working at this point. Many will stay at a good efficiency level for up to 40 years, while others will start to decline earlier.

No – solar thermal doesn’t generate electricity. Unlike solar PV, solar thermal panels harness the sun’s energy and convert it into heat which is then transferred into your home.

You can have evacuated tube solar thermal panels or flat plate collectors; evacuated tubes are thought to be more efficient that flat plate collectors. They both work by using the sun’s rays to heat a transfer fluid, usually made from water and a type of antifreeze, which is pumped to a heat exchanger inside a water tank in your home. The heat from the exchanger heats the water inside your tank, then when the liquid releases its heat it’s transferred back to the collectors to start the whole process again.

You’ll need to use your solar thermal panel system with a boiler, collector or immersion heater. This is so that the water can be stored and used for your hot water and heating, and also because in the UK, people generally need to rely on another source of heating in the winter. There are fewer sunlight hours in the winter months, so it’s not often possible for solar thermal panels to generate enough heat from the sun to get your water up to temperature.

Whatever the time of year it is, you might want to heat the water up further than your solar panels can manage. That’s why you’ll still need a form of traditional hot water heating, but you should see savings on your energy bills. If you’re currently using natural gas, you can expect savings of around £60 per year on your fuel bills, while if you’re using LPG it could be as high as £100 pr year

Just like other major house improvement projects, some specific requirements must be met to allow for the installation of solar panels on commercial buildings. The main reason why these standards and regulations were established is to minimize the risk of the solar system becoming an issue or potential hazard in the unforeseeable future. So if you’re thinking about buying and fitting new solar panels, you’ll probably want to know whether or not you’ll require to submit a planning permission application for approval before you can proceed.

Fortunately, the installation of solar panels on commercial buildings may be “permitted development which mean you won’t have to apply to the Local Planning Authority for planning permission. There are, however, some important limits and conditions which must be put into consideration in order to benefit from these permitted development rights. Some of the limitations include:

• The solar panels must be installed on a wall or pitched roof that should project at a maximum of 200mm from the surface of the wall or roof slope.
• Equipment placed on a roof should not be within one metre of the external edge of that roof.
• Equipment mounted on a wall must not be within one metre of a junction of that wall with another wall or with the roof of the building
• If the equipment is on the roof of a building, the capacity for generation of electricity across the entire site must not be more than 1 megawatt.
• In the situation whereby the panels are installed on a flat roof, the highest part of the equipment should not exceed one metre above the highest part of the roof.

In general, obtaining a planning permission is very important and as such, you must discuss your position with your chosen installation company before you proceed.

If you want to connect solar panels to a battery, it’s likely that it’s because you want to make sure that you don’t waste any electricity when your solar panels are generating energy but you’re not around to use it. Batteries are particularly useful for homeowners that have solar panels but are out during daylight hours; with a solar battery system, your solar panels will feed the electricity they generate into the battery for you to use when you get home.

If you want to connect your solar panels to a battery, the best thing to do is to get in touch with an MCS-registered company who can talk you through your options. There are different size batteries and the size that’s suitable for you will depend on how much electricity you plan to store and how large your solar panel system is. Some of the top brands of battery storage system include Tesla, SunPower and SolarEdge. If you want to be able to take advantage of selling electricity back to the grid through the Smart Export Guarantee (SEG), it’s worth getting an MCS-registered company to install your battery for you, as you may not be eligible for payments if you connect your solar panels to a battery yourself.

You should also consider whether your solar panel system is a ‘storage ready’ solar system. Today, most systems will be, since battery storage is becoming much more common. This means that your solar panel system will have an inverter that can easily integrate a battery. If this is the case, you should be able to purchase the battery you want and follow the manufacturer’s instructions to install it.

However, it’s worth bearing in mind that electricity is extremely dangerous when handled incorrectly. If something goes wrong, you could electrocute yourself or cause a fire. If your solar panels and battery cause a fire, it’s unlikely that your home insurance company would pay out if you connect the battery yourself. That's why it’s best to ask a reputable installer with all the correct qualifications to connect your solar panels to a battery for you.
