Great company, Mark was brilliant at explaining the process of solar and battery products, his staff couldn't have been more helpful. The whole system was up and running within 3-4 days. A month after installation and what a difference in the electricity bill, I wish I had done this years ago. Thanks Mark and the team.

 Trustindex verifies that the original source of the review is Google. We were looking for a solar/ battery system for our property last year. MW Solar were one of quite a few companies we approached for ideas and quotations. We already had in mind an idea of what we would like the system to achieve. After a while we got completely fed up with some other companies who just didn’t seem to listen to what we wanted and just wanted to fit a bog standard system that didn’t require approval from the grid. If we were going to invest in this we had to make sure it would be worth the investment. One other thing to note is that many of the other companies couldn’t/ wouldn’t tell us who would actually be installing it. I didn’t personally feel happy about this. If you join various forums you will see many poor installations by sub contractors of quite well known systems. I have a friend who used MW Solar for his installation and he was full of praise for the company. After making contact with them myself the first thing was that I felt listened to. Any queries I had, and there were quite a few ! were answered/ explained in a manner that I could understand so we decided to go ahead with them. The whole installation by MW Solar went well and we are very pleased with the end result. It’s about 3 months since our system (Sigenergy) was installed and the Gateway feature has proven it’s worth in the recent winter storm when we had a 3 day power cut but we still had an electricity supply :) . We are also definitely saving money on our bills even in winter so it will be interesting to see the total savings after 12 months. I’d definitely recommend MW Solar if your looking for a reliable installer.

 Trustindex verifies that the original source of the review is Google. I have no reluctance in recommending MW Solar. Mark, Owner, explained and quoted for three options explaining them very clearly. His costs were good and I am very satisfied with the installation. He has a great manner and is very approachable.

 Trustindex verifies that the original source of the review is Google. It’s fair to say that I was already convinced that a solar energy system would be a very good investment and it was on this basis that I approached three companies to see what they could offer.  One was a large organisation operating nationwide, one was a smaller organisation covering the whole of the south west and, finally,  MW Solar who had been recommended by a near neighbour. Most reputable companies providing solar systems probably offer good equipment but the key concern for me was the actual installation of the components.  The nationwide company was very much “one size fits all” and I got the feeling that the equipment would be fitted by an anonymous crew in a way that made it easy for them.  It didn’t seem possible to engage with anyone about the practicalities of the installation, most likely because the people on the end of the phone had probably never installed a system themselves. It was clear from the outset that MW Solar were in a different league to the larger companies.  Mark Warden has a tremendous in-depth knowledge, not only of solar energy systems but of electrical installations and building work as well.  He made several suggestions to improve the placement of the roof panels and arrive at the optimum positioning of the inverters and batteries.  I think it is unlikely that the other two companies would have provided so much input to optimise the installation even supposing they had the ability. MW Solar installed a nominal 9 kW array of panels with two 4.9 kW Victron Charge controllers and two 5kW Victron inverters operating in parallel.  Two BSL batteries provide a total storage capacity of 10.2 kWh.  A fixed display panel by the inverters indicates the flow of power in real time, and gives access to all the system settings.  Alternatively, I can monitor and control the system from my phone or iPad.  The Victron system is very flexible and storage strategies can be easily changed.  Recently, I have been keeping the batteries fully charged at all times to provide domestic back-up power in the event of a power cut.  Very useful in a rural area where overhead power lines can be brought down by storms.  Soon, I will switch back to using stored power at night to reduce power consumed from the grid. I am very pleased with the quality and professional look of the installation, which was completed within a week.  Mark and his team were very focussed and efficient, and I wouldn’t hesitate to recommend MW Solar to anyone considering a solar energy system.  The installation was commissioned at the end of July 2025 and I have been pleasantly surprised by how much power the system generates, even at dawn and approaching dusk.  I just wish I had done this years ago!

 Trustindex verifies that the original source of the review is Google. Great service, installation and product. It was great meeting Mark and, from the outset, talking about what we would like and how he could give us what we wanted, manage the installation and options to expand if we wanted. He provided and accurate quote, scheduled the work to integrate with the other tradesmen that were working at our property and finished with all waste removed. After service is also great! I cannot recommend MW Solar highly enough.

FAQ's

Your questions answered

Are solar panels really worth the money?

First things first you will be generating your own electricity, and depending on the size of your system and whether you opt for battery storage, you could save up to 75% on your electricity bills. You could also benefit from the SEG (Smart Export Guarantee) and actually get paid for your generated electricity.

With battery storage, there is also the benefit on being self-reliant in case of grid failures/black outs.

We would always recommend you do your own research, solar is a big investment and you should be sure that it is right for you. There is a vast amount of information out there about solar energy, you can use the internet, blogs and forums and other peoples experiences to make your decision. We will always go the extra mile to ensure that our designs fit your lifestyle and that we illustrate how a PV system would could benefit you.

Can I really get paid for electricity I generate?

Yes!

The Smart Export Guarantee (SEG) is a government backed initiative that was launched in January 2020 after the Feed-in-Tariff (FIT) scheme closed to new applicants in 2019.

SEG licensees determine the rate you are paid for your electricity you feed back to the grid, this is also depends on your tariff and the terms of that tariff. The only requirement is that the tariff must always be greater than zero, but these tariffs can be fixed or variable.

To be able to benefit from most SEG tariffs, you will need a MCS certificate to prove that your system is up to industry standards. MW Solar are MCS accredited and will issue you all relevant certification upon completion of works.

To find a list of energy companies that are SEG licensees, check the Ofgem list of suppliers.

How much money will a Solar PV system cost me?

The good news is that the price of solar panel installation is decreasing, the main reason for this being that the demand for solar panels is increasing year upon year.

The cost of your system and installation will vary person to person, as everybody has different requirements and lifestyles.

MW Solar understand that every installation is different and take pride in ensuring that the systems we design are unique to each clients requirements.

We have a range of products available to our customers, from extremely high end products made in The Netherlands, to the more common solar panels and products on the market.

With over a decade of experience with many different products, we can provide you un-biased advice for your system.

We are always happy to have a no-obligation chat.

Do I have to have battery storage?

No, you do not need to opt for battery storage, and you can always add this in at a later date. You may have a restricted budget or are just keen to experiment with your own needs first.

Installing battery storage with your Solar panels will let them charge up as a secondary load, giving you back up energy to use later on at night when the solar panels cannot power the home.

Battery storage gives you more control of your energy usage and can make you less dependent of the National Grid.

Are all homes suitable for solar?

The short answer is no, not every house/home will be suitable for solar.

Ideally you need to have a South, East, or West facing roof to get the maximum sunlight and get the most from you solar panels.

Generally you won’t need planning permission as solar panels are seen as ‘permitted development’, exceptions being a listed property or ground mounted arrays.

We will always offer our honest opinion when we quote a project and if it’s not worth it, we will tell you.

Will solar panels add value to my house?

According to a study conducted by Effective Home (who specialise in Solar Panels), it was found that sale prices for homes with solar systems rose by around 14%.

There are a number of reasons for this:

The literal value of the Solar Panel system

The aesthetic – Having solar panels is a talking point, it’s cool, it’s aware, it’s “doing something”, it’s keeping up with the Joneses or being the Joneses..

Electricity bill savings, or even the SEG rates.

If you can demonstrate before and after costs or electricity having had solar panels installed we have found this helps a lot.

How long will they last?

The industry standard for most solar panels’ lifespans is 25 to 30 years. Most reputable manufacturers offer production warranties for 25 years or more.
