FAQs
We appreciate that the world of solar PV can be quite complicated. At Helios Energy we’re always more than happy to chat to you on the phone or in person about any of your queries. We have also put together a handy FAQs page just in case we can answer your question with the click of a button.
Solar PV is generating electricity from the sunlight. Panels, mounted normally on a roof space, use the sunlight to generate DC electricity which then flows through an inverter to convert the DC in AC – the electricity type most used in your home or business.
Panels are getting more efficient every year. The panels we install are generally between 300W and 375W but can have more output.
The amount of electricity produced really depends on the size of the system, shading and orientation. Generally speaking, we estimate for every kW of solar PV installed, you will generate around 1000 kWh per year.
We have clever spreadsheets and calculation tools which take your individual circumstances into consideration and can more accurately predicted your proposed systems output. We provide a breakdown of this with every quote we send out.
Yes of course. We work alongside many fixing system manufacturers who have solutions for almost every type of roof out there flat or pitched.
This really depends on the size and variables of your system. When we visit you to discuss your options, we will give you a good indication of timescales. Generally, a 4kW system will be fully mechanically and electrically installed in two or three days.
Having been involved in the industry for a substantial amount of time this problem is not uncommon. We have great contacts with manufactures to get to the bottom of this problem and help with any warranty claims. We also have the knowledge to advise you on alternative options if needs be.
Yes, battery storage systems work any solar PV panels. It works to store the electricity your panels produce for use whenever you like.
The Tesla Powerwall for example guarantees 90% efficiency for up to 10 years after install. Different manufacturers have different guarantees and warranties – we will make you aware of these during the survey and quotation phase of our process.
The rate of charge will depend on your car and on your charge point. Many manufacturers of charge points have different charge modes dependent on your needs e.g: the my energi Zappi has a fast, eco and eco+ mode. Zappi will deliver up to 7kW provided the supply connection is suitably rated in fast mode which will charge most cars as quick as possible
David Cook2024-05-29Great customer service and support post installation. I had a problem with the bird guard for the panels a year after installation. Helios fixed the problem without quibble and very speedily. It’s great to deal with a company that you can rely on.Michael Ryalls2024-05-23Such a great firm from planning and design after home visit, to fitting and replacement of faulty inverter for PV panels and powerwall 2 battery. All working fine. Already saving money. Charming fitters, (special mention to Gav). The owner (Will) fell and damaged his back at his home requiring in-patient treatment but still kept in touch. His Son Laurence took the reins smoothly and coordinated scaffolding, fitting and replacement of the faulty inverter to suit my schedule. Great Job. Many thanks from a very satisfied customer.Edward Bennett2024-04-29Laurence and his team did a fantastic job installing my Sola Panels and Battery Storage system, which involved going to extra lengths to insure it was integrated successfully with a Heat Pump supplied by others. Nothing was too much trouble, a great bunch of guysIan Farminer2024-01-13Helios Energy was used as the installer by the supplier of our solar system. An amazing team arrived to fit our system. We would like to thank, Laurence, Gavin, Russ and Aaron for all their hard work during the install. Having met the team, we would highly recommend Helios. If only we had known of them in the first case.Darren Edwards2023-11-04I used Helios to supply and install a solar panel and battery system in April having had them them recommended by a neighbour and seeing the quality of their work. They listened to my requirements and concerns and installed a system that I am very happy with. They did a great job installing the panels and running cables so they regained out of sight. They also installed the inverter and batteries in my garage to take up as little space as possible . Their pricing is as competitive and they used good quality equipment. I have had a couple of queries regarding system tuning since the install and they have assisted with these. I would highly recommend this small family run company.Ian Francis2023-10-13Helios installed solar panels, batteries and EV charger. They were very responsive and professional. I highly recommend.Ian Challand2023-10-12I have an existing solar and battery installation and needed an additional battery. I researched several companies and chose Helios based on price, location and knowledge. I found them to be very reliable, and they kept me informed every step of the way. I found them to be thorough in asking me what I needed and the best way to implement my needs and to deliver and install my products efficiently and to always clean up afterwards. This si the company the others should aim to emulate.Douglas Elder2023-02-07Extremely speedy job putting up our solar panels and very happy to explain as they went. Also extremely nice guys!Les Beer2023-01-13Good people to deal with, Will et all supplied my kit about 4 years ago, very professional installation with good advice tooJohn Knights2022-10-30Absolutely satisfied with Helios excellent, informative service.
