OK of course lets get straight to the point :). Although I’m afraid this isn’t a straight forward answer. There are many variables that directly affect the cost of a system not the least of which is the size of system, PV-BatteryCombined or PV-Battery only, makes of panels/batteries/inverters, types of inverter, roof area, difficulty of installation site etc. As a rough estimate however a 4Kw combined system would be in the region of £12k-£14k and would produce a return of approximately £37k-£44k, does this ROI sound appealing enough?

“The quick answer is NO as the Feed in Tariff finished in April 2019, however the great news is as a result of the inroduction of SEG (Smart Export Guarantee) scheme by the Govt combined with access to the unique AI interface provided you can generate significant profits on an ongoing basis, which is why this makes so much more sense financially than ever before. It’s also the reason why you should arrange a survey to see the potential return on investment that can be achieved on your property. Would you like to arrange a survey?”
Wonderful so you already know the benefits of PV which is fantastic. The answer is absolutely YES. By combining the battery system with your PV we can ensure you both increase and achieve the maximum ROI on your original investment as well as benefitting from the SEG scheme.
We make sure all our installers are both insured, certified/accredited and experienced. Every one of our installers is sigend up to the HIES Scheme endorsed by both Nick Ross and George Clark. HIES IS a leading consumer protection organisation covering the installation of home energy products. Their promise is to ensure all consumers are respected, protected and educated on their home improvement journey. Does this answer your question?
It is possible to be self sufficient YES but without knowing the energy consumtption levels or fuel types used in your home then this is an impossible question to asnwer immediately. If you use alternative fuels to electricity for your heating, hot water and cooking then the answer of course is NO but If you’re all electric then again it will depend both on consumtpion levels and the size of array/battery system that your property can take, but could be YES? Would you like us to help you find out if you could be completely self sufficient?
What a fantastic question, we’re so glad you asked us. The answer is a resounding YES, although to maximise the ROI you should really be advised if it’s possible for your property to use a combined PV array then it would advisable. Would you like to find out what solution is available for your property?
Without surveying your property all we can say for sure is that it will defintely improve the EPC rating (Energy Efficiency Rating) of your property, which of course forms part of the home report that determnes the value of your home. In addition as your home is now generating an income there is a case for selling this as part of your property in addition to making it a much more attractive proposition for any future buyers as a result of the reduced energy bills, more environmentally friendly and guaranteed income. Would you like to see how our solar solution this could impact your income, property value and EPC rating?
YES although, it’s likey it would be the Battery-AI element only package you could use, which would still allow you to benefit both from the trading platform and in receiving cheaper energy rates. To answer the question confidently and accurately though we would really need to conduct a survey of your property to provide the correct answer. Would you like to arrange to meet with one of our specialist solar surveyors in your area?

Legal and Planning Permission requirements

In England and Wales, the domestic installation of mounted solar panels is likely to be considered ‘permitted development’, meaning that there is no need to apply to the council for planning permission.[1] The following conditions must be met, however:
* Solar panels must not be installed above the highest part of the roof (excluding the chimney)
* Panels should protrude no more than 20cm from the surface on which they are installed (roof slope/wall face)
* Panels should be installed, so far as is practicable, to minimise the aesthetic impact upon the building’s exterior
* Panels must not be installed on a property located within the grounds of a listed building
* There are important exceptions to the permitted development rule, such as if your property is listed or located in a conservation area. It is advisable to check with your local planning officer if your property falls into these categories.

While an average lifespan of solar panel modules is expected to be 25 years there are some models that will continue to function long after 25 years. Like any other product, Manufacturers offer warranties of varying lengths however on average when discussing PV Panels the following usually applies:

  • 10-year limited product warranty (materials and labour)
  • 25-year limited power warranty (typically 10 years at 90% power output and 25 years at 80% power output).
  • Workmanship and materials warranty of one or two years
  • Batteries (non-grid systems / hybrids) roughly 5-15 years
  • Inverter(s) warranty of between 5-10 years
  • System component warranty
  • There are many factors that must be borne in mind
when considering warranties for you solar panel system. These include the workmanship of your installer and the labor and parts they used, inverter(s) and the solar modules themselves. All of which fulfill the desired requirement of a reasonable power output over the entire life of the system and ensure the return on investment initially deliberated.
in 2020 there are literally hundreds of panels of different types, dimensions and power outputs. For domestic arrays they usually vary from 250w to 400 watts per panel. The Energy Savings Trust (EST) estimates that a stereotypical 3 bed house in the UK uses an average just over 3000 kwh per year. With this in mind a 4kw-5kw system would provide enough energy to cover this.
The better way to ask this question is what size of system will my property be able to take? Typically an average panel would be in the region of 17sq ft and so 15ft x 15ft would allow for a 3kw system, 20ft x2ft would allow for 4kw. The output of your system will depend on size, direction, tilt and efficiency and While a south facing roof is the most desired it’s by no means essential as you can easily have your array placed on both East and West facings and still produce substantial returns on your investment.
