Renewable Energy Specialist FAQs

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.

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.

How do I connect solar panels to a battery?

Most people want to connect solar panels to a battery when they’re not at home all day to use the electricity they generate, or generate more than they consume over a day. Solar batteries are a great way to maximise the savings on your energy bills since you can use every unit of electricity you generate.

If you want to connect your solar panels to a battery, the best – and safest – way is to ask an MCS-registered company to do it for you. 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.

But it’s worth remembering that electricity is extremely dangerous when handled improperly. 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.

how long do solar panels last?

How Long Do Solar Panels Last?

As an alternative form of energy, solar panels are becoming increasingly popular all thanks to a wide range of benefits it provides. It does not produce any emission which makes it greener and more environmentally friendly, it requires little maintenance and are less likely to break down, they also come with warranty that are always quite long mainly because of the life expectancy of the average solar panel amongst many other advantages. Therefore, if you’re considering to purchase and install new solar panels within your home, you’d also probably want to know the time period in which they’re expected to last. In this article, we aim to help you answer this question so you can make an informed decision going ahead.

As a result of the rising energy bills as well as the desire to be greener, solar panels are becoming increasingly popular by the day in the UK. The most recent models of solar panels in the market possesses an expected lifespan of 40 to 50 years as well as warranties that keeps them protected for a minimum of half of that period. These warranties also serves as a guarantee to the solar panel’s level of performance over the first half of their lifespan. Several warranties will guarantee that the performance will not go below 80 percent before the warranty lapses. And even more importantly, some solar panels are crafted in such a way that they wouldn’t drop below 80 percent performance level throughout their lives.

However, in order to derive maximum benefits from your solar panels for a long period, there’s a need to ensure they’re properly maintained at least once a year throughout their lifespan.

Is it worth getting a solar battery?

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.

How long do home solar batteries last?
How long home solar batteries last depends on the type of battery you have and how often it’s charged and discharged (when electricity is fed into it, then used later on). Generally speaking, a home solar battery should last between 5 and 15 years. Lithium-ion batteries last longer than lead acid batteries. Lithium-ion batteries are more common these days because they’re more cost effective. A lead acid battery is the cheaper option at around £2,000, but it’s likely to last between 5-8 years. On the other hand, a lithium-ion battery may set you back around £4,000, but will last between 11-15 years. So you can see that it’s well worth choosing a lithium-ion home solar battery. It’s also worth considering that a solar battery’s lifespan will be reduced if you over-discharge it. When your home solar battery is installed, you’ll be left a manual which will tell you its depth of discharge, or DoD. This means how much you can use the battery before recharging it – it's not as simple as letting the battery run down to 0% then charging it again. In fact, this can significantly shorten your battery’s lifespan. If your solar battery system’s DoD is 80% and its capacity is 5kW, make sure you charge it before you use up 4kW to help prolong its life. Luckily, most lithium-ion batteries have a DoD of 80% or more, so you don’t need to worry about not being able to use much of the electricity stored in your home solar battery. This is another reason to use them over lead acid batteries, because their DoD can be as low as 50%.
how many solar panels do i need?

When you’re about to transform from the standard electricity to solar energy, what determines your solar system’s size is the amount of solar that’s required. The amount of solar that you’ll need, on the other hand, requires considering the end goal, be it to increase money savings, reduce environmental contamination, maximize Returns On Investment ( ROI), or just to copy what the neighbour’s done.

In order the determine the number of solar panels that is needed, the first step would be to calculate the number of kWhs that’s currently being used. A kWh is what’s used to determine the amount of energy that has been incorporated over time which the utility uses to bill you. What’s strongly recommended to create a suitable range is a 6 to 12 months average of your household electricity bill. Other factors that can play a key role in the determination of the number of solar panel needed include the following:

✓ Sunlight exposure hours. In order to know just how much energy your solar panels will generate, there’s a need to know the number of direct sunlight hours you should expect on a daily basis. For example if you stay in a region that’s usually very sunny, then it’ll be reasonable to expect more energy production per panel than regions that are usually cloudy.

✓ Angle and size of the roof. Roofs with a lot of workable space may require to let go of some efficiency opting for larger and cost effective panels to achieve the targeted energy. However not all homeowners have sufficient roof space or shade coverage for the solar panel they actually want. Also, the degree at which the roof slants will also determine if the sunlight is hitting the panels well enough and the amount of energy that can be generated thereof.

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.
