Solar Panel Installer FAQs

How do I connect solar panels to a battery?

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.

Which solar battery is the best?
With so many different solar batteries on the market these days, it can be difficult to know which solar battery is the best. Luckily, we’ve picked out some of the best solar batteries on the market so you can take a look at their stats and figure out which one is best for you. Powervault 3: 8 kWh model This lithium-polymer solar battery has a useable capacity of 8 kWh and a depth of discharge (Dod) of 100%. It’s covered by warranty for 10 years. Cost: From £7,020 Tesla Powerwall 2.0 The famous Tesla Powerwall has a huge useable capacity of 13.5 kWh and also has a 10-year warranty, with a guarantee that it will work at 70% capacity during those 10 years. It’s a lithium-ion battery. Cost: From £6,500 Powervault 3: 4 kWh version This more modest solar battery from Powervault has a capacity of 4 kWh, but benefits from the same warranty length and DoD as its 8 kWh brother. Cost: From £4,470 SolaX 3.3 This more affordable solar battery from SolaX has a 10-year warranty and a good DoD of 90%. Cost: From £4,010 LG Chem RESU 6.5 LG are an up-and-coming player in the solar market and their 6.5 kWh battery is one of the most affordable on the market. Its DoD is 90% and it comes with a 10-year warranty. Cost: From £3,043 To decide which solar battery is best for you, you need to consider:
  • The power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it
  • How often you think you will need to charge your battery
  • Your budget
  • Whether you care about having the latest technology and a recognisable brand name
When you’ve made these decisions, you can narrow down your choices. It’s also worth asking a few MCS-registered installers for their opinions on what they think would be best. Of course, they want to sell you whichever brand they supply, but they probably chose this for a reason. Ask them to give you a few pros and cons for the brands they recommend and see if this matches up with your research.
how do solar panels and batteries work together?

How Do Solar Panels And Batteries Work Together?

With solar panel system rapidly becoming an ubiquitous phenomenon within the modern society, several homeowners in the UK are just coming to terms with the numerous benefits offered by the system. The solar power’s popularity has even led to the rise of another renewable technology - solar batteries able to store excess solar power that can be used later. Now several companies such as Tesla are now building solar batteries that can be fitted alongside solar panels for your building. So how exactly do solar panels and batteries work together? Let’s have a look!

Solar panels make use of the sun light to generate electricity and as a result, they can’t function when sunlight is absent - giving a big issue of how to power your house when it’s dark. In the event whereby this occurs, you’re afforded two options which is either to contact energy providers to buy electricity or purchase a battery storage system.

So what’s the function of the battery storage system? Basically when your solar panel provides electricity which is not needed right away, a solar battery will work to convert the DC electricity into AC energy which is going to be stored for later use (when you actually need it). in other words, your solar panels charge the batteries when you do not require the energy they’re generating right away.

As a result, when it’s dark and the solar panels are no longer functioning, your system will tap into the energy that’s already been stored by your battery for later use. This way, you can be totally independent of the National Grid, which implies more savings on your electricity bills.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries you’ll need for your house.

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.

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.

They’ve had lots of training and hold qualifications in handling electricity and installing solar batteries, so they will be able to recommend the best battery for your solar panels and for the among of electricity you use. Some of the brands they might recommend include Tesla, SolarEdge and SolaX, but there are many more to choose from. If you want to send electricity to the grid from your battery to receive Smart Export Guarantee (SEG) payments, it’s also worth leaving installation up to a registered installer. This is because you might not be eligible for payments if your battery wasn’t installed by an MCS-registered company.

However, if you do want to have a go at connecting your solar panels to a battery, it’s worth finding out whether your system is ‘storage ready’. Most relatively new systems will be, since batteries are becoming more commonplace. If your solar panels are storage ready, they will have an inverter that can easily have a battery added to it. If this is the case, then you should be able to buy the solar battery you want and follow the manufacturer's instructions to install it.

If you don’t get the solar battery connected properly and something goes wrong, it could cause a fire or you could electrocute yourself. If a fire breaks out due to your battery, it’s unlikely that your home insurance company would pay out since you connected the battery yourself. That’s why it’s always worth speaking to a registered installer to install a solar battery storage system for you.
