Solar panels
What factors should I consider when evaluating solar panel costs?
Consider equipment quality, warranties, installation expertise, financing options and long-term savings on energy bills. It's essential to weigh upfront costs against potential long-term benefits to determine the overall value of the investment.
Are there financing options available to help cover solar installation costs?
Yes, there are various financing options available to help cover solar installation costs, including solar loans, leases, PPAs and government incentives such as grants or tax credits. These options can help make solar installation more affordable and accessible to homeowners.
How do solar panel costs vary by provider?
Solar panel costs can vary between providers based on equipment quality, warranties, installation expertise and pricing strategies. It's essential to compare quotes from multiple providers to ensure competitive rates.
How do solar panel costs vary by region?
Solar panel costs can vary by region due to differences in labor rates, permitting requirements and market competition. Generally, urban areas may have higher installation costs than rural areas due to higher labor and overhead expenses.
How much does solar panel installation cost?
Solar panel installation costs vary depending on factors such as region, provider, system size, equipment quality and installation complexity. On average, an install oost for a three-bedroom home ranges from £7,000 to £10,000.
What are solar panels?
A solar panel is a panel composed of solar cells. These solar cells are capable of generating solar energy when exposed to sunlight. We refer to this process of converting sunlight into electricity as the photovoltaic effect. Thanks to solar panels, increasingly more households and businesses are using renewable solar energy – and thus less energy from fossil fuels. Solar panels are typically installed on the roofs of homes or businesses. We are also seeing increasingly more solar meadows. These are solar farms placed on land. However, at Soly, we deliberately choose not to offer this.
How do I determine how many solar panels I need?
The number of solar panels you need depends on your current power demand and, more importantly, your future power consumption. The demand for power is growing. For example, because we want to cook on an electric hob or charge our electric vehicles at home. We therefore also advise you to estimate your power consumption liberally so that the capacity of your solar panel system will match your power consumption well into the future.
What are the benefits of black solar panels?
Solar panels vary by manufacturer. This is also why you sometimes see blue solar panels and other times black ones. The advantage of black solar panels lies mainly in their higher yield per square metre as well as more yield when directly exposed to sunlight. In turn, this is because the monocrystal solar cells are arranged in a fine line and generate more solar energy than polycrystal solar cells. In addition, black solar panels also suit most roofs better in terms of appearance. The black solar panels here provide a pleasant and neat finish.
Within what time will my solar panels be installed?
As you may have noticed or read, there has been a huge growth in the number of households looking to have solar panels installed. This growing demand is positive but also has a downside. The period between accepting the offer and installing solar panels can sometimes be a little longer. Incidentally, this applies to all solar panel suppliers in the UK. Soly will keep you as informed as possible about the process between accepting the offer and the actual installation. So you know where you stand.
How do I know whether my roof is suitable for solar panels?
Whether your roof is suitable for solar panels depends on several factors. For example, whether your roof can support the construction of solar panels, whether it receives enough sunlight and to what extent your roof covering is suitable. We will be happy to inform you about this.
What should I pay attention to when purchasing solar panels?
If you prefer to purchase solar panels, a one-time investment ensures that you become 100% owner of the solar panel installation on the roof of your home. We always advise you to look at the right price/quality ratio. In addition, Soly allows you to determine the capacity of your system based on your power consumption, thereby making you less dependent on the grid both now and in the future. In our Solar Configurator, you can request a non-binding offer for solar panels.
Do I need to apply for a permit to install solar panels?
Yes, you need planning permission in order to be able to install solar panels. That’s because this counts as a large-scale alteration or remodelling of your home. Fortunately, there is a permit exemption in the UK for installing solar panels on a sloping or flat roof. You must be able to meet the following conditions:
  • The solar panels are integrated into the roof
  • The solar panels are mounted several centimetres above the roof
  • For a flat roof: solar panels are installed no higher than 1 metre above the roof edge
  • For a pitched roof: the solar panels are at approximately the same pitch as the roof
For more information on the conditions necessary to be able to install solar panels, you can always contact Soly.
Can I also monitor the yield of solar panels?
Understanding the yield of solar panels and knowing when to use solar energy effectively. That’s what we at Soly are committed to. That’s why the Soly monitoring app allows you to track everything. Within the application, we also provide you with useful tips and tricks so that you can get the most out of your solar installation.
My solar panels are not displaying yield. Why?
Are you not seeing any yield from your solar panels in the monitoring app? This can have several causes. With SolarEdge, it may be due to a fault. Read more about it here. There may also be a problem with your inverter. Do you see unusual lights on the inverter and don’t know what is causing this? If so, our advisers will be happy to help you.
Why is the yield from solar panels lower at high temperatures?
High temperatures and lots of sun – and yet a lower yield from your solar panel system? This may sound strange but is not that unusual. Solar panels benefit from a lot of sunlight but not necessarily from extremely high temperatures. That has to do with functionality. This is because the system needs cooling and ventilation in order to perform optimally. At extremely high temperatures, the system finds it difficult to dissipate heat. This means the optimum yield is not achieved.
Do I have a warranty on my solar panels at Soly?
With Soly, you are entitled to various warranties for solar panels. We have created a special page on which you can find all forms of warranty in a single overview. Warranties on solar panels can include the manufacturer’s warranty on the product as well as warranties related to the installation and functionality of solar panels.
Should I have my solar panel system checked periodically?
If your solar panels have been on the roof for a long time, there may be some wear and tear and general ageing. That in itself is not dangerous, and a periodic check of solar panels is therefore not necessary. Does your solar energy yield deviate considerably from expectations? If so, you can always reach out to us for more information and support.
Do I have warranty on the microinverter?
You have a warranty on the solar panel microinverter. This warranty is twofold; you will receive a warranty for proper installation and operation of the microinverter by Soly. You will also receive a manufacturer’s warranty from the manufacturer of the microinverter. These manufacturers involve SolarEdge or Enphase.
Home battery
What is a home battery?
A home battery ensures that your surplus generated solar energy is temporarily stored so that you can use it as soon as your solar panels are not generating enough solar energy. This allows you to run your washing machine and dishwasher in the evening, for example. A home battery is sometimes also referred to as a home accumulator.
What are the advantages of a home battery?
A home battery allows you to temporarily store solar energy for later use. The greatest advantage can be found in the efficiency of your (renewable) energy consumption. Thanks to a home battery, effective use of energy from solar panels increases from around 35% without a solar panel battery, to as much as 70–80% with a home battery.
What are the features of a home battery?
The features of a home battery primarily relate to its capacity and dimensions. The dimensions of a home battery can vary considerably depending on the type of battery. For example, the size of home batteries ranges from one to two shoe boxes. By the way, your home battery will be installed in a space-efficient place. You will therefore not be inconvenienced by it.
How do I choose the best home battery?
Choosing the best home battery is done based on the price, quality, and capacity of your system. We always recommend a home battery tailored to your daily power consumption and the capacity of your solar installation. We also take into account your future power demand. So you always have a system that adjusts to your energy needs.
What is the price of a home battery?
The price of a home battery varies by type and size (capacity). At Soly, we currently use three different batteries with solar panels. More information on the prices of home batteries can be found here.
Is there a payback period on the home battery?
Purchasing a home battery is a major investment. Of course, there is then also a certain payback period here. As you use your own generated solar energy more effectively, you will need to draw from the energy grid even less often. This can save you a lot of money. The payback period of a home battery is about six years.
What is the storage capacity of a home battery?
The storage capacity of a home battery varies and depends on the number of solar panels on your roof. At Soly, we use a home battery with a storage capacity of 3.5 kWh, 7 kWh, or 10.5 kWh.
How many charge cycles does a home battery have?
The home battery typically has a charge cycle of 5,000 to 10,000 (dis)charges. Moreover, charging and discharging the home battery also causes a small amount of energy loss (about 3–5% on average).
Does Soly offer home batteries?
Yes, we currently offer a trio of home batteries. For more information, visit our page: Soly home battery.

How much money can I save with solar panels?
Solar panels provide renewable, green energy and are therefore always a good choice. However, many people will also look at the financial aspect. Quite logically. Thanks to solar panels, you can save hundreds of pounds every year depending on the size of the solar panel installation.
Can I sell solar energy back to the grid?
Once you have solar panels on your roof, you will be able to start generating solar energy. You will not use all the power generated by your solar panels (directly) yourself. That means you will sometimes have to deal with excess power. You may inject that excess power into the energy grid. Depending on the energy provider different tariffs are applied.
Why is feeding energy back less efficient than consuming it yourself?
Once you inject energy back into the energy grid, you will be eligible for an injection allowance. Interesting – but not as interesting as consuming solar energy yourself. This is because the injection rate (fee) for solar energy that you supply to the energy grid is lower than the reverse route (when you take energy from the energy grid). So as soon as you can’t generate enough solar energy and have to draw energy from the grid, you are financially worse off. Using your own solar energy as efficiently as possible is therefore important. To encourage this, you can opt for a home battery from Soly. The next step towards a sustainable future.
Can solar panels be recycled?
Good news! Solar panels are fully recyclable. The main component of solar panels is silicon. This is a unique mineral that does not lose its qualities and can therefore be used indefinitely. The glass and aluminium of solar panels are also easy to separate and reuse. This makes solar panels particularly sustainable. Read more about recycling solar panels.
