FREQUENTLY ASKED QUESTIONS

Solar PV stands for Solar Photovoltaic and it refers to the technology used to convert sunlight into electricity using solar panels made of photovoltaic cells. These cells are typically made of semiconductor materials such as silicon, which, when exposed to sunlight, generate direct current (DC) electricity.

Solar PV systems consist of multiple solar panels connected together to generate higher power output and can be installed in various sizes, ranging from small residential systems to large-scale solar farms that generate electricity for entire communities or utility-scale applications. They offer numerous benefits, including reducing electricity bills, lowering carbon emissions, and providing a renewable and sustainable source of energy.

While solar panels are most efficient in direct sunlight, they can still generate electricity on cloudy or rainy days. However, their output will be reduced compared to sunny days.

The size of your solar panel system and local weather patterns will determine how much electricity you can generate during cloudy conditions.

In most cases, you will not need planning permission to install solar panels on your roof, as they are often covered by permitted development rights.

However, there are some exceptions to this rule, such as if your property is a listed building or in a conservation area. If you are installing solar panels on a flat roof, there are also some conditions that must be met.

If you are unsure whether you need planning permission, you can either discuss your particular circumstances with the Local Planning Authority for your area or feel free to get in touch with Solar Tech Solutions, using the contact form below, and we'll be more than happy to help!

Since the 1st of April 2022, there has been a zero-rate of VAT on the installation of energy-saving materials, including solar panels, in residential accommodation.

Although there are a few exceptions, if you use the same provider for both supply and install there is no VAT to pay on the solar panels, the solar inverter, the batteries, or on the cost of the installation.

Moreover, in February 2024, the UK Government extended the VAT exemption to include standalone battery installations and retrofitted solar batteries, so it's now cheaper than ever to add storage to your solar PV system.

Note: Prior to February 2024, VAT relief on batteries was limited to batteries that were installed at the same time as solar panels.

A solar inverter is a critical component of a solar photovoltaic (PV) system. Its primary function is to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is the standard form of electricity used in homes, businesses, and the grid.

In grid-tied solar PV systems, the solar inverter synchronizes the AC output with the grid's frequency and voltage. This ensures that the solar-generated electricity can be seamlessly integrated with the electricity from the utility grid. It also allows excess electricity to be exported back to the grid if the system produces more power than is being consumed onsite.

Solar panels are suitable for most homes and businesses that have a suitable roof or space for installation. Factors such as roof orientation, shading, and local weather conditions can affect the efficiency of solar panels.

Solar panels work by converting sunlight into electricity through the photovoltaic effect. When sunlight hits the solar panels, the photovoltaic cells within the panels generate direct current (DC) electricity. This electricity is then converted into alternating current (AC) electricity by an inverter, which can be used to power your home or business.

The installation time for solar panels varies depending on the size of the system, the complexity of the installation, and local permitting requirements.

In general, residential solar panel installations can be completed in just a few days, while commercial installations may take longer.

Typically, grid-tied solar PV systems that do not have battery storage will automatically shut off during a power outage. This is done for safety reasons, as grid engineers who are working to fix the issue could be injured if the powerlines are still "live".

However, systems that do have battery storage can continue to provide power during outages by effectively "islanding" your property.

These systems continuously monitor the grid and if it goes down, they will stop power being fed back into the grid, creating a sort of energy "island" that allows you to keep the lights on whilst others are in the dark. All whilst making it safe for engineers to fix the issue.

Solar panels typically come with warranties ranging from 20 to 25 years, but they can last much longer with proper maintenance.

Most reputable solar panel manufacturers guarantee that their panels will still produce a certain percentage of their original output after 25 years.

The amount of space required for solar panels depends on factors such as the size and efficiency of the panels, your energy needs, and the available sunlight at your location.

One of Solar Tech Solutions' professional installers can assess your property and recommend the optimal size and placement of solar panels.

Yes, solar panels are environmentally friendly because they generate electricity without producing greenhouse gas emissions or air pollution. By using solar energy, you can reduce your carbon footprint and help combat climate change.

Additionally, solar panels can help reduce dependence on fossil fuels and promote energy independence.
