It is now just over one year since Techfor installed my solar panels (please see my post at the time). We had several companies visit to quote and each produced their projection of energy generation. Techfor's projection was the lowest and some were significantly higher. The reason for this extra post one year on is to advise that Techfor's projection was within 1% of what we actually achieved. Glenn from Techfor spent far more time on his survey than the others and this is proof that he did the job properly.

Techfor Energy had designed and supplied solar panel system for me 15 months ago, so this was the logical extension. Glenn explained exactly what it would do (in words of one syllable), so I went ahead. The three men arrived on time and with all they needed. The work was neatly carried out, all 'mechanical' work being finished by evening, but there was a problem with the batteries discharging. All wiring was double checked, and Glenn decided the problem was in the computer software either in America or France. This he would sort out and left no stone un-turned until it was. Several phone calls to check if things were working, until two days later all was running smoothly. I wish all companies were as much of a pleasure to deal with: Glenn and his team are professionals to their fingertips, dedicated to utilising solar power for as many people as possible, and ensuring the work is completed to the highest possible spec. I am a total computer ignoramus, and Glenn is patiently teaching me how to read my graphs and get on top the technology that has been installed. My grateful thanks for all the hard work done by the team.

First rate service from planning through obtaining consent and installation. The team thoroughly explained the options giving quite a wide range and then installed in a day. They are in touch with the latest technology (micro-invertors etc) and worked out the most effective solution. They may not be the cheapest but provide a comprehensive guarantee which we had to use when a tile fell off shortly after installation and smashed into a lower roof. Thoroughly recommended.

As the summary below may go beyond your immediate requirements, I can happily recommend Glenn Ashby and his company Techfor Energy Ltd. for the following reasons: ÔøΩTechfor Energy sent their Technical Director out to carry out a comprehensive site survey. Not only was he the Technical Director, but also the owner of the business and was very knowledgeable and professional. The survey and Q&A session took the best part of 2.5 hours and included measurements of all trees likely to impact the arrays. ÔøΩTechfor was the only supplier to mention the Government grant for EV charging points ÔøΩTechfor was the only supplier to state the need for sister rafters ÔøΩTechfor was the only supplier to talk me through the G59 application requirements and manage the whole process I consider the system provided as value for money and would happily use Techfor Energy Ltd. again. Summary I selected several local companies using a combination of both Which Local and Checkatrade.com, I sent out emails requesting both advice and quotations. Techfor Energy Ltd. were the first to respond. I received a call from John Appleby from their sales team to discuss my requirements the very next morning. As soon as John called, I knew I was dealing with a knowledgeable individual and a professional company. John answered all my initial questions and subsequently arranged for a free technical survey to be undertaken. This was confirmed by email within the hour. Two days later, Techfor EnergyÔøΩs Technical Director Glenn Ashby arrived on schedule and carried out a thorough survey and shading analysis of the property, garden and surrounding buildings and vegetation. He thoroughly inspected the structure of the roof and confirmed that sister rafters would be required owing to the dimensions of the existing rafters. The data gathered and input to his tablet, combined with photographs taken, enabled Glenn to provide me with several options on the spot. Glenn spent another hour of so explaining the options with both honesty and clarity, assisted by a folder full of technical specifications and photographs. By the time he came to leave, I was quite confident as to the system specification I wanted and this was provided to the other companies in order to facilitate a like for like comparison. One or two days after the technical survey, I received a brief courtesy e-mail from the design team to keep you informed of progress and let me know that my design options were underway and later that same day I received detailed quotations for the design, installation and commissioning of both a 4kWp and an 8kWp solar PV system. The following week I received the other quotations (all subject to further survey) and by the time I calculated the additional charges for items omitted or to be upgraded, it was a simple choice. Techfor Energy would provide a system that would largely protect me from rising energy/fuel costs while providing a reasonable return on investment. Having placed my order with Techfor Energy for an 8kWp solar PV system, Techfor Energy got straight into seeking Distribution Network Operator (DNO) approval for the more powerful 8kWp system with a guideline of 20-30 working days for the green light to proceed. A month later, I received confirmation that DNO approval had been granted and we agreed on a preferred date for installation. With a great crew on board, the installation took two days following the erection of the scaffolding. Everything went to plan and the work was carried out neatly and with minimum disruption. The scaffolding was removed the following week just in case there may have been any equipment failures during the first few days necessitating any replacement. The day after commissioning, an Energy Performance survey was carried out and the certificate registered online, the certificate being required to qualify for the higher FIT tariff payments. The Techfor Energy team were then able to fill in the relevant information on my feed in tariff application form so that I could complete it and send it off to my energy supplier for registration. The following day, I received the ÔøΩSolar PV Info PackÔøΩ from Tom and the admin team, comprising all the system schematics and technical information as well as operating instructions, certificates and warranty documentation. I can therefore happily recommend Glenn Ashby and his company Techfor Energy Ltd.

As with other reviewers, I have absolutely no hesitation in recommending Techfor Energy. The staff in every department that I had any contact with were very personable, highly efficient and extremely professional. They were always very happy to answer clearly and precisely all the questions I asked. Their quotation was extremely detailed and well laid out. They worked very hard to ensure that my installation would be completed and all necessary paperwork finished on the Friday as the new FIT rate was coming in on the following Tuesday. My installation was split over two locations and in three orientations. In the three weeks the system (3.7 KWp) has been in place, it has generated 300 KWh of energy. The minimum that has been generated in a day has been slightly over 3 KWh and the current maximum stands at 23 KWh. I would strongly suggest that you include Techfor as one of your 3 or more companies that you invite quotations from. You will then be able to see why all the reviews have been so positive.

Originally, I asked Techfor to do remedial work on solar panels installed by one of the numerous 'cowboy' outfits in the industry. I was so impressed with Techfor's attention to detail, customer support and skill of its workforce that, without any selling pressure, I commissioned a second set of panels. I now have a 4kw system with Solar iBoost; since installation, I haven't used any mains electricity or gas to heat water and my general metered consumption has plummeted. In an industry blighted with fly-by-night cowboys Techfor is a beacon of professionalism!

TechForEnergy installed a residential 6.4KW / 23 Panel Solar System with microconvertors for us, with a Tesla wall battery to be installed in the spring, (due to the lead time on the batteries). Having done a lot of research and spoken to 5 different solar companies, I was very happy to proceed with TechForEnergy. They are professional, courteous and very very knowledgeable about solar systems and battery systems. They were very proactive in keeping me informed of developments and in helping me with the FIT application. I would highly recommend them.

From the outset Techfor inspired confidence. This company is very knowledgeable about solar technology and the latest developments, and is able to explain the whole installation process clearly. We were impressed that the company, although based in Guildford, was prepared to travel to mid-Wales to survey the property, a thorough and detailed process which took several hours. The quotation produced was clear and very informative giving a good indication of all the costs involved. The installers were punctual and thorough, and left the loft tidy and clean. They worked hard even through some very wet weather to complete the installation on schedule. The electrical installation was very tidy, and the electrician explained the operation thoroughly, as well as helping to install the apps to monitor the system, and we understand that Techfor will continue to monitor the system remotely over the first year of operation. The system was installed on time and on budget, and has since worked well, despite some very poor weather and we look forward to some substantial savings on our electricity bill. Techfor assisted with the Feed-in Tariff application and obtained the various permissions required to connect the system to the grid. We were very pleased with the quality of the work and the equipment installed, and would recommend this company highly.

We made several false starts to get solar panels so I was particularly critical when Glenn Ashby arrived for the pre-installation survey. It didn't take very long for him to set my mind fully at rest. Glenn was ultra thorough, very knowledgeable, attentive and communicative, pro-active and pleasant and produced an excellent proposal with two options (4kW without Tesla and 6kW with Tesla). After reading the proposal I had a number of questions and suggestions which were all addressed in a lengthy call, satisfying me as to how things would be done and work. We went for the 6kW Tesla option and we've had the solar installation working for about 10 days now, without a hitch. Because it's November and raining the energy harvesting isn't as it would be in summer but we are seeing the benefits already, and are already changing our energy usage behaviour further to maximise the benefit. Of course we are now awaiting the Tesla power wall which due to demand wasn't available to instal at the same time as the panels. I am confident that once it arrives, the installation will be as smooth and uneventful as was that of the panels. Glenn's team worked quickly and was neat and tidy, and a pleasant bunch (I guess we were lucky to have Glenn himself as part of the team....). Thoroughly recommended.

Hi Glenn, Have realised I never wrote to you about how pleased we are with the Tesla installation. From the installation in June up until mid October we used almost zero electricity from the grid. The last 10 days we have been on Economy 7 and have switched to the ‘advanced cost saving mode’ and have already prioritised the use of more than double the cheap tariff compared with the expensive one. This should give considerable cost savings over the winter. Thanks again to you and your team for your expertise.

Prior to deciding on a solar installer I have read many reviews on websites such as ‘checkatrade’ and ‘Which? Trusted Trader’. Techfor Energy was the only company that was repeatedly praised for their high standard of work, customer service and time management so I decided to contract this company, and I have not been disappointed. Techfor Energy installed my 2.5 kWp Solar PV system with Enphase micro-inverters and bird mesh, which prevents pigeons from nesting under the panels. I have been very impressed with their service and top quality. Recently, some of the clips from the bird mesh had popped out due to the adverse weather. When I rang Techfor Energy and spoke to Glenn Ashby he sent me his team the next day to replace the clips free of charge. I would highly recommend Techfor energy for any solar PV project as they are very professional with an eye on the detail.

We only wish we had done this sooner! Glen Ashby impressed us immediately with his technical knowledge, thoroughness and patience in ensuring that we understood the best system for our house and all that was involved in solar PV. He did the most thorough survey of the three firms we asked to quote, answered all of our questions in detail, adjusted his quote as we changed the specification and his price was fractionally the lowest on a £ per kWh basis for an excellent system. In the end we specified a large (6.2kWp) system, including an Eddi to heat the hot water (brilliant kit, saves on the gas bill as well) and a Harvi, as we had the roof space and were buying an EV. It is all now working brilliantly! Like some others, we have waited a year (installed in August 2019) to match Glen’s predicted output, which was 5,325 kWh, with actual output. At an amazing 5,903 kWh, this is 11% more than expected and our electricity bill has plummeted from £1,200 to £400 and the gas bill is down by £200! We have since added a Zappi as the EV has now arrived and every mile we have since driven has been powered by the sun (it charges through the main part of the day when electricity usage is very low) – this has got to be the way ahead for green energy! Techfor was brilliant from start to finish and we unhesitatingly recommend them.

I originally contacted 3 solar companies, TechFor Energy came recommended. I spoke to the Technical Director Glenn over the phone first, before having a visit and chat with him. No pushy sales here, Glenn was thorough, really took time to understand what I wanted to achieve, he also shared a lot of reading material, external links and reviews to ensure I really knew what I was signing up for and to ensure I got the right system for my needs. The survey and quote was to a very high standard, options clearly spelled out and with competitive pricing. When it came to installation, we had a professional and friendly team, which is important when you have them in and around the house for prolonged periods. Every step of the way we were consulted, communication with the team on the ground and their office was great, and quite a few questions I asked pre and post installation have all been answered thoroughly. Glenn in particular takes a personal interest in ensuring everything is working well throughout the process. Overall, I highly recommend them as a company, and am very happy with my Solar Panels and Tesla Powerwall, bring on the sun!

Contracted this company to assess and install solar panels and battery. The service started with a 3 hour survey including shading, refundable on purchase. This was followed by panel installation and (at a later date) a Tesla Powerwall. On each occasion I was contacted beforehand to arrange installation, and was kept in touch with what was happening. The fitting team were the same ones each time, were polite, neat and tidy, respected our house and furnishings and finished on time. Without prompting, I was asked to stage payments (deposit up front, further payment prior to installation, substantial payment on completion). An excellent service.

Our recent solar upgrade to add extra panels and a Tesla battery to our system originally designed and installed by Techfor Energy a couple of years previously was once again a very professional job. From the initial assessment which took a number of hours, to the final commissioning, great care and attention to detail was evident from the whole team. The work was carried out over the period specified and exactly for the quoted cost. The Increased generation capacity and battery have allowed us to run an EV and power the house for free over the first month of use. We have exported more energy than we have used on sunny days. We are very pleased with the outcome. I chose Techfor Energy initially as they were a Which magazine trusted trader, Checkatrade listed and MCS certified.

Excellent job! Of three firms approached Techfor Energy were able to provide the most detailed advice, comprehensive survey and quote, for a fully bespoke 5.95kW solution. This was based on a range of options with realistic energy projections. Glenn was patient in explaining all the pros and cons around creating the optimum system and his team was efficient and responsive throughout the installation. The system effectively runs itself, with only minor tweaking by app (which gives some great insights into power generation, battery flows, and usage). Glenn has further advised on the best settings to benefit from Octopus’s ‘Flux’ time-based tariff. One month in, results are better than expected despite the winter gloom. Highly recommend.

I recommend Techfor Energy: 1 . They gave a professional survey before you commit to anything. 2. Very skilled tradesmen – roofers, electricians, technical sales, all of which are difficult to beat. Techfor Energy had already installed solar panels for me in 2018, which I was very happy with, and this year I asked Glenn to return in order to install batteries and an EV charger. I am now off-grid until the end of the summer. Thanks to Glenn for recommending Utilities Warehouse, my off-peak electricity over the winter will be under 6p per kWh. Next, an EV purchase to help repay my outlay. I expect it to take 7 - 8 years to achieve this on the assumption that most of my miles will be derived from energy from my home charger and the reduced electricity tariff. I now have solar panels, solar water heating, two Tesla batteries, Tesla Gateway, and a Zappi EV charger. However, a big plus is the software that runs the system to help you save money - believe it or not, the system uses tomorrow's weather forecast to make decisions for you!
