Some properties do not lend themselves well to having a set of solar panels on the roof, typically due to the angle or direction of each aspect of the roof – although most homes can benefit from a set of solar panels.
It may be that the size, direction and style of your roof dictate the shape of solar panels we suggest or limit the total number of solar panels you can install in the usual grid shape.
If in any doubt, please send us an image of your roof, or request a quotation where we can inspect your roof and advise on its suitability.
Most homeowners do not need formal planning permission from their local authority, as residential solar panel installations are normally treated as permitted developments.
As the Essex solar panel installation experts, we can walk you through the other considerations.
We endeavour to make every project as seamless as possible, and the same applies to our quotation process. You can either give us a call, drop us an email, or visit us at our Colchester offices for more information.
Another option is to complete our contact form with a few details about the renewable energy options you are interested in and let us know the best time to call you back to discuss.
RossApril 10, 2024Got a 5kw solar and 8kwh battery system installed by Cahill and had a great experience from start to finish. Would 100% recommend them. Customer service was top notch and the installation was quick and straightforward. They made it easy and while it’s still early days, it’s good to see how much you’re generating and saving with the metrics in the app. 5 star!Emma PSMarch 21, 2024Cahill Renewables installed my solar and battery solution November 2023. They have been incredibly professional and prompt at every stage from initial enquiry, installation and after care service. They were so efficient with the paperwork, which enabled me to be exporting back to the grid within 4 weeks. I am really enjoying being a solar power user.Garth SylvesterMarch 19, 2024We chose Cahill Renewables to fit our Heat Exchanger as of all the people we talked to, they were by far the most professional in their attitude, explaining exactly what we would need. The team who came to fit it were there on time and got straight to work. They made a very neat job under quite difficult circumstances as we have a small bungalow with not much room to move anything about. Apart from providing coffee and tea we didn’t have to lift a finger, for which, now getting on in years, we were very grateful. They made an extremely neat job running the pipes under the house, so, no ugly fittings running along skirting boards, although of course this made the job harder for them it was their idea and we were extremely grateful. The whole service from beginning to end was extremely professional. We wouldn’t hesitate to recommend Cahill Renewables in the future.Robbie TindalFebruary 26, 2024Having decided to have solar panels installed Cahill Renewables were one of five companies we approached for a quote. Right from the start we were impressed with their response, their efficiency and willingness to listen to what we wanted and to answer all the questions we had. The quote we received was competitive and having agreed a date and timescale for the work it all went ahead as planned. All of the guys who came on site were polite, considerate, careful and professional. They worked extremely well as a team to ensure the job was completed in a timely manner and kept the site clean and tidy. We enquired about having some additional electrical work done linked to the solar installation and this was scheduled to fit in with the existing work whilst they were on site. We have no hesitation in recommending Cahill Renewables to others. A great team in all respects.Airsoft GBJanuary 31, 2024Cahill Renewables have been absolutely great installing our home solar system. They have been incredibly helpful from the initial quote, interpreting our needs to provide the final quote, installing all the panels and battery and then patiently explaining how the Tesla battery system works. A very helpful and competent team which we throughly recommend.Stephen DJanuary 22, 2024Joe was incredibly efficient, patient and helpful. Couldn't praise more!CBF LazaroDecember 5, 2023Ended up not going ahead due to technicalities and planning permission requirements on my specific situation, but cahill renewables were the ones to go with if I did go ahead. Josh was polite and knowledgeable, got a very fair quote from them for a ASHP install and the quoting process was very pleasant and non pushy.Praful LakhaniNovember 1, 2023EXCELLENT - Every team from Sales to Scaffolding to Electrical to installers and tilers were just exceptional. Ours is a slate roof and required more careful work and matching. THEY EXCELLED in every respect. . They arrived on time, were most courteous and very clean and tidy.Peter LaurenceOctober 23, 2023A thoroughly pleasant and efficient company who were a great help throughout the solar panel "process". Great products, professionally fitted and our questions answered very promptly. A pleasure to do business with.Jonathan FarnhillOctober 18, 2023I have just had solar panels, an inverter and batteries installed in our house, and the service and support we received from Cahill Renewables was first class at every stage of the process. I have no hesitation in recommending them as a highly competent provider and installer of PV systems
