Tech for Energy were professional from the outset. The survey demonstrated how we could benefit from an additional 5 panels & a Tesla battery installed in the garage as well as improving the efficiency of the existing 9 panels. The work was completed in a thorough and very satisfactory manner, and on-time despite one very windy day. Very satisfied with the results. Our electricity consumption from the grid dropped 97% on the first full month (May 2024) of use.

Solar System Upgrade

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.

Techfor's expert report helped me get my money back
Customer Service
Quality
Value
Techfor Energy's technical director was brought in after I'd been swindled out of more than £3,500 by a fly-by-night company claiming to be solar power experts. Luckily I'd paid by credit card, and Which? had advised me that I had the right to compensation under Section 75 of the Consumer Credit Act 1974. The card supplier's Complaints Dept was defensive and dismissive, but the tone changed when I was eventually transferred, months later, to their Section 75 Dept. These people demanded an opinion from an independent expert, but they gave me a full refund immediately when they saw Techfor's authoritative report, which was detailed and realistic and said the whole thing had probably been a scam.

Another outstanding interaction with Tech for energy. They installed my solar system and a Tesla Powerwall at the end of last year which I am very pleased with. Glenn wanted to make sure that I was getting the maximum benefit from my system. He knows the energy market and the tech very well and took the time this month to follow up on my system and guide me through adjusting the settings on my battery to mine maximum value from the market. I now charge my battery at cheep rates when the battery has forecast dull weather the coming day and (the battery) leaves it to the sun if the forecast is for sun. Brilliant. thanks for taking the time Glenn.

I fitted my first solar and Tesla battery system back in 2018. I was sufficiently impressed with the survey, installation and after sales service and support that I received from Techfor Energy - I fitting a second system a year later at another property. The second system was at my home address and with the purchase of a fully electric car I achieve extra benefit when surplus energy produced goes to charging the car. Now that is what I call saving the planet. Now six years on from the first installation I am getting fast and helpful advise from the Techfor Energy team whenever I have a question. That type of aftercare service is hard to find these days.

Glenn and his team did a superb job. They designed and installed our solar panel system, complete with a Tesla Powerwall storage battery and a MyEnergi-'Eddi' hot water unit. We are with "Octopus" and are using their overnight reduced ("Intelligent") rate. We also have a MyEnergi "Zappi" car charger. We are saving very substantially on electricity. We are extremely pleased and would not hesitate to recommend TechFor Energy.

Engage Tech4 Energy. Beware using 3rd party suppliers for your green energy projects

Tech4 Energy originally initially installed our Solar PV, Tesla Powerwall II battery and myenergi equipment. They did a fantastic job and the system has been in operation for 3 years now. HOWEVER, we made the mistake of going with a 3rd party supplier (major UK "green" electrical supplier) to install a Zappi EV charger. BIGGEST MISTAKE EVER. The engineers from the 3rd party company were not trained, did not understand how to integrate the Zappi charger into our (myenergi) installation, violated Heath & Safety and electrical compliance standards. PLEASE DON'T MAKE MY MISTAKE, USE SOMEONE LIKE TECH4 ENERGY.

Excellent company, I have worked with Techfor Energy twice. They installed my first solar system in 2013 and I have been so pleased with it that I asked them to upgrade and augment the system in 2023. After a thorough survey (not a sales pitch) I went with Glenns advice and now have a system that charges my car, heats my water and a Tesla power wall that stores excess for overnight use with green energy I am still exporting to the grid and Glen has taken the time to follow up to ensure the system is working to its optimum output. The quote was detailed and easy to understand. The team were very polite, professional and efficient. always on time and tidy. They have also been available for rare after sales queries. I am delighted with my seamless system. Completely off grid for most of the year I have already had my 1st off grid week in January. I will look to Techforenergy for advice on future developments in solar technology. I recommend them to anyone interested in solar systems. Thanks Glenn and the team.

Techfor are based locally near us. Glen Ashby took great care with the initial survey and design work. Brought us along at each stage by clear explanations. No hard sell. We were impressed by their whole approach. The job was done in two stages - the installation of the panels, and then the installation of the Powerwall batteries. The batteries were on a very long delivery because of high demand for Tesla batteries. The installations were carried out efficiently and professionally. The batteries have made a very big difference - we got to the stage in the summer of resenting having to pay for any electricity even though we run an electric car. There was one small glitch with the battery installation which Techfor fixed straight away.

Solar pv and battery installation

Tech4energy was recommended to me by my neighbour who had a solar pv system fitted by them. I contacted them and Glen came out and did a thorough survey, and gave advice as to what would be the best system for us. We wanted to be able to go off grid as much as possible. Heat our water, charge EVs, and store excess energy. So quote accepted, we went ahead. The install team were polite, friendly, and professional. 100% happy! We achieve everything we want from our system. So when the sun shines we can heat our water ( A new water cylinder with bottom fed immersion heater required). Charge the Tesla powerwall battery, and charge an EV. A Zappi charger allows fast charging off the grid and a slower charge from solar energy. On a cloudy day, obviously energy production is less. 5kw/h on a sunny summer day max. 0.5 to 1.5 kw/h on a cloudy day. We can still run the house and charge the battery, and some water heating. Not enough for an EV charge. Winter time will be less obviously. So far in 6 weeks we have not used any energy from the grid. We use the battery at night and morning until the sun does its job. We are on Intelligent Octopus for off peak energy at night 7p/kw/h, so we can charge an EV cheap rate if we need to. Outgoing octopus for exported energy. 15p/kw/h. Glen advised us on all of the above, and we are extremely happy. Thanks Glen. One of the best things we have spent our money on. I highly recommend Tech4energy to anybody thinking of having a solar pv system fitted.

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.

In every respect, I found this a good experience with the Techfor team. The project was discussed together until I was comfortable understanding all aspects before proceeding - I wanted no surprises! Once agreed in concept, communication in terms of timing of the installation (20 panels) was proactive and helpful. As such, this went smoothly and in line with my expectations. The team that did the job were professional and helpful. All questions were answered clearly. No issues. Even the removal of the scaffolding went smoothly (different team). The project was done on schedule and in line with my budget. The stand out service here for me was the consistent pro-active nature of the service by the entire team. They seemed to look at things through my eyes first - before their own! It was overall a novel and refreshing experience.

Really helpful advice, not pushy, genuine chap
Spoke to Glenn looking for a solar thermal quote. His first reaction was that for our needs, supplementing our existing PV solution would be a better long term investment (about the same cost but far lower ongoing maintenance costs). He advised that we were outside of his area, but rather than just saying bye, he then took the time to walk me through a number of options for panels, pros and cons, installation sites (including the fitting to use) and options for expanding the system in the future with a battery, to use as a basis for talking with more local installers. It is not often you come across someone as genuinely helpful these days.

The process of working with Tech For Energy for our solar array was fantastic from start to finish. From first contact with Glenn, through the survey and installation, you can tell they not only know their stuff but also are very passionate about it. The install team was lovely, and in places went above and beyond to do the job correctly, rather than just what would have worked. We're very pleased with the results and the panels are now performing well, even though the weather is not ideal for this period of the year. It's great seeing the stats and analytics, I've become a little obsessed already. Can highly recommend.

The team did a wonderful job installing a brand new system comprising forty solar panels which were spread across two roofs. The original survey was very thorough and he spent some time discussing our needs and how best to accommodate them. The installation went ahead as scheduled and completed a day earlier than forecast. His team were a delight to have on site, being efficient, courteous, tidy and helpful. I would have no hesitation in recommending Techfor Energy to anyone considering installing a Solar PV system.

Glenn and his team should be congratulated for an extremely well-managed project. As part of the quote an initial site visit many measurements were taken to calculate the actual generation that we could expect from the solar panel array and these to date have been very accurate (project completed nearly 6 months ago). We are very pleased with the professionalism of the team and the quality of workmanship. We have not had any problems at all with the system and would highly recommend tech for energy.

I had been speaking to Glenn for nearly a year before lockdown provided the final impetus to get work done. I initially asked to look at solar panels on my shed but was told that was not possible. Glenn's style was the opposite of pushy sales guy from a big on-line company who had tried to pressure us until 8pm some weeks before!. Glenn explained the challenges of our roof orientation and how to overcome them and was clear on benefit of Tesla battery but supply challenges on that so we ordered before Christmas and work was scheduled 3 months after with battery arriving in June. Scaffold was erected professionally and work was done to time . Slight challenge of the box to house the "teg" unit and associated electrical gubbins but I was able to build something to cover it . Top job overall and I would recommend them.

Excellent solar energy installation performing well

Glenn of Techfor Energy is very knowledgeable on all aspects of home energy. He was happy to discuss a range of options for our solar installation, and clearly explained the pros and cons of different options - in roof v on roof, different panels, microinverters v Solar Edge, etc. We finally settled on a 5.7KW 16 panel LG system with microinverters, an Eddi to capture excess solar energy in hot water heating and a Tesla battery. The battery is still to install due to Tesla's long lead times. We already had a Zappi electric vehicle charger. The installation team worked cleanly and efficiently. The system is doing everything we had hoped. With the myenergi app and the Eddi and Zappi, we have complete control over where the solar energy is used. A separate app enables us to see the individual solar panel performance, instantly and over time. The peak power output is set by the microinverters at 4.8kw, which is achieved on sunny summer days, but even on cloudy days generation meets household needs and more. We have run our electric car for most of the time since installation on sunshine. In addition we have not used any gas water heating over the summer, and there has been significant excess power exported to the grid under the SEG scheme. We are delighted with the system and look forward to the Tesla battery installation, which will avoid early morning and evening grid usage, and enable use of low cost overnight electricity in the winter.

Techfor installed PV panels in 2016. Additional PV and Tesla battery installed operational from 21/7. What a difference. Very little grid power since then and only at night if battery goes to its minimum setting. System has incredible technology managing house demand between panels and battery. Techfor are a thoroughly professional organisation headed by a very knowledgeable leader, courteous fitters/electricians always keep the workplace clean. We got more than Techfor said we would get from our installation. This is a big investment we are making so choose the best. Techfor
