Frequently Asked Questions
Our Solar Installation FAQs cover the most common concerns and questions people have about installing solar/PV panels at their property. From how much solar panels cost to how long solar installation takes, we can help provide the information you need to make an informed decision.
The cost of solar panels has reduced by over 80% in the past decade and with rise in energy prices at an all-time high, there’s never been a better time to invest in a solar installation and reduce your reliance on the national grid. Our competitively-priced solar packages start from £6,824 which includes 10 solar panels, a solar inverter and installation.
This is the equivalent of asking “how long is a piece of string?” as there are many factors which affect your potential savings! How much energy you use during daylight hours versus non-daylight hours is a big factor so it’s advised that you use appliances like your dishwasher or washing machine at a time when your panels are generating energy. Your panels also need to be clean to work effectively – having dirty panels will affect your ability to generate energy and therefore save on energy bills.
In most scenarios, you won’t need planning permission as installing solar panels are likely to be considered as ‘permitted development’ meaning you don’t need to apply for planning permission. But there are exceptions, for example, if your property has a flat roof, is listed or is in a conservation area. If this is the case, check with your local authority to see if you need to get approval from your council’s building control team.
Typically 3 days. On day 1, the necessary scaffolding will be put up. On day 2, we’ll install the panels and electrics. And on day 3, we’ll finish the install and commission the system. Please note, these are typical timescales but of course, the weather and other factors may affect the completion date.
There are a lot of misconceptions about how the direction and angle of your roof affects suitability for solar panels. Contrary to popular belief, your roof doesn’t have to be South-facing (West and East-facing roofs are fine too) and your flat roof can be just as effective as a diagonal roof for capturing daylight.

If you view the value of solar panels from an environmental perspective then reducing your reliance on fossil-fuel energy and using the natural energy produced by the sun is undoubtedly a great way to reduce your carbon footprint. From a cost perspective, the price of solar panels is down and the cost of energy is up so there’s never been a better time to take the plunge on PV panels. You can start to reap the rewards of reduced energy bills from day one of your install being completed depending of course on how much daylight your panels are able to absorb. And of course there is the potential to earn money back from selling any surplus energy generated back to the grid.
But if you’re wanting to know how long it takes to cover your investment in solar panel installation, estimates suggest it takes between 4-10 years – contact us today for a free proposal. It’s worth considering whether you plan to move house in the foreseeable future as it’s not generally recommended to uninstall solar panels to take to your next property.
To encourage installation of renewable energy generation and help the country meet its net zero emissions commitment, the UK Government has scrapped VAT on solar panels until 31 March 2027. This applies to first time installs only. Further extensions on any system will be subject to current VAT rates.
It can be worth informing your electricity supplier about your recent solar PV panel installation, as they may be able to offer you the Smart Export Guarantee where they can buy any surplus energy from you.
To make sure you’re sufficiently covered, you should always let your insurance provider know about any significant changes you make to your home.
The electricity produced by your solar panels is converted from DC (direct current) by the inverter to AC (alternating current), which your home is run on. The electricity is then taken from the inverter via an AC cable to your distribution board, where it is used to power the circuits in your home.
Critical Power and Control Ltd provides a 2 year no quibble guarantee on parts and labour. Solar panels have a 25 year manufacturer’s warranty and the other components of a solar install (inverter, batteries, etc) tend to have a manufacturer’s warranty of 8-12 years.
Solar batteries are available in a range of sizes or storage capacities, from 1kW to 13kW. But when choosing your battery storage option it’s not just about the size/capacity, it’s about other factors like discharge rate/power output which determine how much energy can be drawn from the battery. This is sometimes referred to as useable capacity. Useable capacity is less than total capacity as you can’t discharge them completely as it damages the battery. Based on your expected electricity usage, we can help choose the best battery storage option for the needs of your household.
There are a range of EV chargers on the market and it can be difficult navigating through the options. In our experience, a 7kW model will suit the majority of domestic scenarios. We tend to favour a specific brand which is solar compatible and generally accepted as the best on the market for the price. Contact us to discuss your needs and arrange a free home survey.
