Solar Panel Installer FAQs

What size home solar battery do I need?

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.

Are solar panel batteries worth it?

Whether solar panel batteries are worth it depends on how much you’re at home and how big your solar panel system is. If you’re at home most of the day and your solar panels only generate enough electricity for you to use while for that day, then a battery probably isn’t worth investing in. However, if you have a large system that generates more than you can use or you’re out most of the day, then solar panel batteries are definitely worth it.

A solar battery storage system works by storing the electricity that your solar panels generated until you need to use it. That’s why they’re great for people that are out all day – your solar panels generate electricity all day whilst the sun’s out, but no one’s home so you’re using minimal energy except for things like your fridge and any appliances on standby. Most of the electricity charges your solar panel battery. Then, when you get home, your battery will discharge, and you’ll use all the solar electricity that your panels generated during the day.

Solar batteries are also excellent for people with large solar panel systems that generate more than they use in the day. Any electricity that you don’t use during the day will charge the battery, so in the evening when the sun goes down, you’ll just use the excess electricity that’s stored in the battery.

To work out whether solar panel batteries are worth it for you, you’ll need to work out how much of your solar electricity you’re using already. If you’re at home and you’re able to run your appliances all while your solar panels are generating electricity, a battery might not be worth it. Also, if you’re receiving export payments from the Feed-in Tariff Scheme (FITs) or the Smart Export Guarantee (SEG), you might want to look at the rate you’re getting paid. If it’s a good rate, it might be more cost-effective to continue exporting unused electricity to the grid. Speak to an MCS-registered installer that will be able to help you work this out.

How do you find an installer for commercial solar panels?

Commercial solar panels installation companies are everywhere. However, it’ll be a great mistake to think finding one nearby for your project would be the least of your worries, as both cost and reliability comes into question. This is even more worrisome when you’re fully aware that your solar system potentials can only be fully maximized depending on how well it’s installed and how good your installer is. If you’re also facing the same challenge, then you’ve come to the right place. In this article, we’ll share with you some tips on how to choose a nearby professional and reliable commercial solar panel installer who’ll ensure you get immense value for every penny spent. Let’s take a look!

  • Ask for recommendations. Personal recommendations is always the best way to go, when looking for a commercial solar panel installer or any other tradesperson for that matter. Installation of a commercial solar system is a major undertaking which comes with a lot of costs, so if you’re going to do it the least you can do is ensure you do it right. Carry out your research, ask friends and family, neighbours and loved ones if the know of any reliable commercial solar panel installer in the local area. If they have one they’ve used, you can request for the cost, quality of the job done, the duration of the project and any other detail you feel you should know.
  • Internet. In modern times, you’ll hardly find a progressive-minded business without an online presence. As a result, finding a service on the internet is as simple as it gets. A simple Google search have been helping people find their desired service providers with relative ease for so long. Or use the Quotatis directory to find a commercial solar installer. To get the right commercial solar panel installer online, it’s advisable to check their reviews as well as testimonials before moving forward.
How long does a Tesla Powerwall battery last?

Tesla’s top-of-the-range battery storage system is still one of the most expensive on the market. It has a huge 13.5kWh usable capacity and can even keep you up and running during a power cut. But how long does a Tesla Powerwall battery last? And does this mean it’s worth investing in one?

The Tesla Powerwall 2.0 comes with a 10-year warranty. But Tesla says that it should last way beyond this – at least 5 years longer. The standard warranty says that it should work at 70% capacity for the full 10 years – so if it loses more than 30% of its storage capacity within that time, it should still be covered.

While the Tesla Powerwall does last a long time, it has a large capacity that most average households won’t require, and it’s a costly option. After installation, the Powerwall 2.0 will set you back between £6,500 and £9,000, so ideally you want it to last past its 10-year warranty.

Before you splash out, consider the size of the solar panel system you want to install or you already have. Will it generate enough electricity to make it worth storing in the Powerwall? If not, are you expecting to upgrade your solar panels to a larger system in the future? If you are, then it might be worth investing in a Powerwall. It might also be better to wait until you come to upgrade your solar panels – the solar battery price trend is going the same way as solar panels, so they will probably continue to decrease in price as more people adopt the technology.

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.

Can I buy solar panels?
Yes, you can buy solar panels without having to have them installed by the same company. There are lots of online companies that will sell you single solar panel modules, but there are also lots of businesses that offer DIY solar panel kits with everything that you need to install solar panels yourself. If you’re looking to buy solar panels without installation, you should expect to spend around £4,000-5000 on a 3.5kW system, which is the average system installed in the UK. When you buy solar panels to install yourself, it’s worth bearing in mind that you won’t be eligible for Smart Export Guarantee (SEG) payments. To receive SEG payments, your solar panels need to be installed by an MCS-registered installer, and if any schemes come about in the future it’s likely that the rules will be the same. It’s also worth doing some sums before you decide to buy solar panels and install them yourself. An average solar panel system installed by an MCS-registered company will cost between £4,500-6,000. While that’s more expensive than a DIY solar panel kit, you can claim SEG payments. According to the Energy Saving Trust, you can make your money back on your solar panels within 16 years with the SEG, but without the SEG it could be up to 20 years – and that’s only if you’re at home all day to use the electricity. So before you go ahead and buy solar panels to install yourself, consider whether it would be better to get in touch with some solar companies to get quotes and see if it’s better to pay more upfront.
How do I test my solar panel?

If you want to test your solar panel system to see if it’s working properly or just to see what output it’s giving, you can do this using a multimeter to measure current, or amps, and voltage.

Before you start, you’ll need to find the voltage (v) and current (A) ratings of your panel. You should be able to find them on the back of the panel. You should also make sure that it’s a nice clear, sunny day to get the best readings out of your panel. You should also check that it’s safe to be up on your roof!

To measure open circuit voltage, you’ll need to make sure that your solar panel is completely disconnected from your system’s regulator and battery (if you have one). Angle the panel towards the sun, and ensure that your multimeter is set to measure volts. Measure the voltage between the positive and negative terminals by connecting the negative contact on the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel.

Then, you can move on to the short circuit current. Follow the same steps as the open circuit voltage, but ensure that your multimeter is set at 10A to start with.

Only try to test your solar panel if it’s safe to do so. If your roof isn’t accessible without scaffolding or specialist equipment, consider speaking to an MCS-registered solar company about your concerns. They may recommend that they come to service your solar panel system.

Is it best to get solar panels installed by a professional?
Yes. It will always be best to get solar panels installed by a professional because they have gone through lots of training and have all the relevant qualifications to install solar panels correctly. Whenever you’re dealing with electricity, if something goes wrong it could cause a fire or you could electrocute yourself, so it’s always worth leaving it to the professionals. The other thing to bear in mind is that it’s best to get solar panels installed by a professional, MCS-registered engineer so you’re eligible for Smart Export Guarantee (SEG) payments. The SEG is a government-backed scheme where your energy supplier pays you for each unit of electricity you send back to the grid. Each supplier can set their own rate, but it must be above zero at all times, even if wholesale electricity prices dip below zero. According to the Energy Saving Trust, if you’re at home all day and live in the South East, combine the savings on your electricity bills with your SEG payments and you could save up to £330 a year, meaning the system could pay for itself within 16 years. If you don’t use an MCS-registered company to install your solar panels, you won’t be able to claim the SEG. It’s also unlikely that you’d be able to claim payments for any other schemes that may become available in the future, so it’s always best to leave your solar panel installation to the professionals.
