Solar panels against blue sky: on the FAQs page

Leading the field of renewable energy

with quality and care

  • Will the Solar Panels be fixed to the tiles on my roof?
    No, Solar panels are typically mounted on Stainless Steel and Aluminium rail system that is fixed to the rafters on a typical pitched roof and using adequate ballast on flat concrete roofs. The PV system is designed to maintain the strength and integrity of your roof, whilst remaining watertight.
  • Should I have a South Facing roof ?
    South facing roofs are best suited for solar generation, however, east and west may generate similar or even better returns, by installing some on the East and some on the West. North facing roofs are best avoided. A well designed ground-mounted system is a viable option if the other options are not available
  • Will Shading from large Trees and Buildings affect the output?
    As a general rule of thumb, if they are within 10m of your house then shading from these objects will affect the output and should be avoided at all costs. Our designers/surveyors will perform a shade analysis as part of any survey conducted and will highlight any shading issues as part of your quotation. There are technologies available that can reduce the effect of shading, however it is worth checking this over with one of our solar design engineers.
  • Is there a New scheme to replace the Feed in Tariff?
    Yes, the Smart Export Guarantee (SEG) scheme came into effect beginning of this year (2020) and the Microgeneration Certification Scheme (MCS) is the route to access. Under the SEG, energy suppliers will be required by law to offer a payment for the electricity households with SOLAR PV panels export to the grid. The legislation puts a legal obligation on energy suppliers with over 150,000 customers to introduce export tariffs by 1st January 2020. MCS certification will be a requirement to qualify for the SEG, helping to safeguard high standards in the industry.
  • Do we need Planning Permission to install Solar Panels?
    Under the Permitted Development Act, planning permission will not be required to install a roof-mounted solar PV system up to 50kWp in size. Planning is required if the building is listed or if it is located in a Conservation Area. In the case of Area of Outstanding Natural Beauty, the planning laws have relaxed considerably in recent years, however, it is always best to check with the relevant local authority. For larger or ground-mounted systems, you may need planning permissions; we can help you with that.
  • How will Solar4us help with the Post Installation Registration?
    Yes, we will inform the relevant Distribution Network Operator (DNO) and Inform Building Regulation authorities in your area. What is the payback period for Residence and Commercial? Typically the payback period is around 8-9 years
  • How will Solar4us address the H&S issues?
    Before every job, big or small, we do Risk & Safety management checks
  • How do Solar Panels work with and without battery storage?
    Solar panels are made up of photovoltaic, short for Photons to Electrons, cells which convert the sun's light energy (Photons) into direct current (DC) electricity. This DC electricity is then converted by an inverter to alternating current (AC) which is either used to power the equipments in the house any excess is fed to the National Grid
  • Do you recommend any particular brand of Solar Panels?
    No, however on every quote we provide an option of two or three well known brands
  • What is the Warranty on Solar Panels?
    The Product Warranty of Solar Panels is about 10 – 15 years depending on the make. This can be extended, however the performance warranty is usually around 25 years
  • Is there any annual maintenance required?
    No, the Solar PV system has no moving parts so needs no essential servicing. Every 5 years or so cleaning the panels with some clean water will help maintain peak performance.
  • Can we use solar at Night?
    Yes, you can. With Li-ion battery storage devices getting cheaper by the month you can now use the electricity generated in the daytime at night. Thus increasing the self consumption and in some cases relying very little on the national grid. In many cases batteries can be added on to the existing PV installation. Solar4us have over 5 years experience in battery installations with PV and can offer a full turnkey solution for solar battery storage. This includes; analysing your suitability and specifying the right technologies for your home and installation. We retrofit home batteries to existing solar PV systems and offer a range of solar, battery packages for
