Q1. Is my roof suitable? |
|
A1. A sloping roof will be suitable providing: 1. It faces south, south east, south west, east or west (or anything in between these). A south facing roof is best and gives the highest output. If your roof is north east, north west or north facing it will still generate power, but not enough to justify the installation from a financial point of view. 2. There is little or no shading. A flat roof will be suitable as long as there is little or no shading. We can find a suitable means of attaching the panels to the roof (either by fixing to the underlying joists or by using free standing mounting frames). Installing panels on a flat roof may require planning permission. |
|
Q2. Is it safe? |
|
A2. In a word, yes! Solar PV systems do not emit any toxic chemicals and there are no moving parts. A solar energy system is essentially just another electrical circuit in the house. Solar PV systems have been around for many years and thanks to current UK legislation you can rest assured that all solar PV system components undergo a rigorous testing regime to ensure they will deliver the required performance in a safe manner for the duration of their life expectancy. All fixing methods we employ have been approved by independent chartered structural engineers. Most roofs are 'standard'; however if your roof is in any way 'non-standard' we will seek advice from a structural engineer prior to installation. |
|
Q3. What guarantees do you offer? |
|
A3. All panels we use are accredited under the Microgeneration Certification Scheme (MCS) and are guaranteed by the manufacturer to deliver at least 80% performance after 25 years. Inverters are guaranteed for 2-5 years (an extended inverter warranty is available at extra cost). We offer a two year workmanship warranty. In addition, we guarantee to investigate and rectify any query or complaint about your system in the first 5 years free of charge, with no call out fee. Our comittment to after sales service is unrivalled. |
|
Q4. How long will a solar system last? |
|
A4. Solar PV systems are built to last a minimum of 25 years. The Feed in Tariff is payable for 25 years, the performance warranty on the panels is 25 years (specifically guaranteeing a minimum 80% original performance). Roof fixings are made of non-corrosive materials. The system life will last longer if it is looked after well. We recommend a five yearly maintenance programme with panel cleaning and inverter inspection. The inverter has a manufacturer’s warranty of 2 years for SMA and 5 years for Eversolar, although both are expected to last longer and extended warranties are available at additional cost. |
|
Q5. How much maintenance is required? |
|
A5. On a sloping roof, very little maintenance is required as the solar panels will automatically be cleaned by the rain; in addition the glass on the panels is self-cleaning glass. As a precaution, we recommend the panels should be professionally cleaned every five years. This can usually be carried out from the ground using a low pressure washer and a long lance (no detergent or abrasives). The inverter manufacturer will typically recommend that the inverter is inspected every five years. We do offer a regular inspection and maintenance programme which will help keep your panels up to the required standard. |
|
Q6. Which products do you use? |
|
A6. We use quality products; specifically we use SMA (Sunny) or Eversolar inverters. SMA is a German company, Eversolar is a Chinese company. These suppliers have been chosen for their reliability and superb track record within the industry over many years. As this is a critical piece of equipment which is effectively the engine room of the installation converting direct current (DC) from the solar array into alternating current (AC) to power your home or export back to the grid, it is logical to choose the most reliable equipment to ensure that your system works optimally generating electricity and earning/saving you money. We offer a range of panels: Trina, Sharp, Romag, Mitsubishi and Sanyo are our most popular brands. All panels are accredited under the Microgeneration Certification Scheme and come with a 5 year defects warranty and a 25 year performance warranty. |
|
Q7. Will scaffolding be required? |
|
A7. For most installations, scaffolding will be required. This is to protect the installation team whilst working on the roof and to comply with health and safety legislation. |
|
Q8. Will there be a lot of disruption? |
|
A8. There will be minor disruption to you as the majority of the works are based upon the roof. Small scale disruption will occur whilst carrying out the electrical works within the house; we'll discuss this with you during our initial assessment so you are fully aware of the work that needs to be done and how it will affect you. But it's minimal. |
|
Q9. How long does the installation take? |
|
A9. Our installations typically take two or three days. We can usually fit your installation within four to six weeks of receiving your signed quotation acceptance. |
|
Q10. How much energy can I expect to generate from Solar PV? |
|
A10. This will depend on the size of system installed and the location / orientation of the system. When we conduct your no obligation survey, we'll inform you about the finer detail, taking into account system size, roof orientation and slope. Rest assured you'll be given a detailed forecast of potential energy output and fuel cost savings. |
|
Q11. What sort of payback time and financial return can I expect? |
|
A11. Based on current levels of Feed in Tariffs and on our current prices, we have calculated payback times of between 11 years for larger systems (2.5 kWp or larger) and 12 to 13 years for smaller systems. The income from Feed in Tariffs is tax free. For a basic rate tax payer, the financial return is equivalent to a 25 year taxable investment paying between 7% and 9% per annum. For a higher rate (40%) tax payer, the financial return is equivalent to a 25 year taxable investment paying between 9% and 11.5%. |
|
Q12. How do the Feed in Tariffs work? |
|
A12. We recommend visiting this website: http://www.fitariffs.co.uk/ for full details on the Feed in Tarrif Scheme. |
|
Q13. What should I ask of any potential solar installer? |
|
A13. Your chosen solar installer should be MCS accredited, otherwise you will not be eligible for the Feed in Tariffs. Also ask:
There are lots of installers to choose from, some are good and some not so good. We would like you to choose SunSolagy to install your system because all of our installers are trained to the highest standards and we are qualified and accredited. If you'd like to see written testimonials from our customers, please feel free to ask. |
|
Q14. What areas of the UK does SunSolagy cover? |
|
A14. We install nationwide. Our head office is in Redhill Surrey; however we have network of locally based installation teams to manage installations across the UK. All installers are employed directly by us - we do not sub-contract work out (except scaffolding), making SunSolagy an ideal choice for the installation of your Solar PV installation for that added peace of mind. |
|
Q15. Is SunSolagy accredited under the Microgeneration Certification Scheme? |
|
A15. Yes we are accredited under the MCS to install solar PV, reference NIC1964. Please note you need to use an accredited installer and MCS accredited solar panels to be able to register for Feed in Tariffs. |
|
Q16. Do I need planning permission? |
|
A16. Recent changes to planning law mean that a PV system on a domestic dwelling usually counts as 'permitted development' and can be installed on a sloping roof without the need for planning permission, as long as the panels project no more than 200mm from the roof surface (our panels will comply with this, as long as your installation is on a sloping roof). If you are in any doubt, we have a standard letter which you can send to your local authority planning department. If your installation is on a non-residential property, a flat roof or if your property is a flat, listed building or located in a conservation area or World Heritage site you will require listed building consent or planning consent. Please remember to tell leaseholders, freeholders, mortgage lenders and insurers about the planned work and remember to obtain the relevant consent. |
