1. What is a PV (photovoltaic) unit?

    A photovoltaic panel is constructed by connecting photovoltaic cells to produce electricity. These cells are based on semiconductor technology that converts solar radiation into direct current (DC) electricity.

  2. What are the benefits of using photovoltaic systems?

    By utilizing photovoltaic cells home or business owners are able to generate electricity from sunlight saving money and avoiding harmful pollution generated by traditional methods of generating electricity like burning fossile fuels or nuclear power. This solar generated energy is used to offset or replace power that would normally be purchased from EAC/AIK.

  3. Which different types of PV panels exist? Monocyrstalline/Polycrystalline Multicrystalline/Thin film

    There are currently four main types of Photovoltaics panels:
    Monocyrstalline – these are made from cells created by cutting thin slices from solid crystalline silicon blocks and are higher in efficiency, but also higher in cost per watt. They are easy to spot because they have a smooth even color, usually black. MandoraSolar uses high efficient monocrystalline photovoltaics panels only. 
    Polycrystalline – these are made from cells created by cutting thin slices from polycrystalline silicon blocks and are lower in efficiency, but also lower in cost per watt. Polycyrstalline silicon is the “chicken nugget” of silicon, made by combining many individual crystals. They are easy to spot because they have an uneven color, usually blue.
    Multicrystalline – a different term for polycrystalline.
    Thin film – these are made by depositing a thin layer of very finely powdered silicon (amorphous silicon) or other photovoltaic material on a substrate. These are much lower in efficiency that crystalline cells, and somewhat cheaper per watt. Their low efficiency makes them undesirable for commercial and residential applications because they consume a large amount of (roof) space compared to mono- or polycrystalline panels.

  4. How does shade affect the performance of a Photovoltaics system?

    One of the leading causes of power loss in a photovoltaic system is shade on a part of the panel or array. Reason: In a photovoltaic panel there usually are either 60 or 72 cells connected together. Each cell produces a certain voltage and amperage. The cells are configured and connected in a combination of serial and parallel connections to produce the correct amount of power. If any individual cell’s performance is degraded by shade, the performance of the entire photovoltaic panel will decrease to a point relative to the worst performing cell. Likewise, in a string of photovoltaic panels: The entire string suffers performance reduction to that of the lowest performing photovoltaic panel. Any installation should be designed in such a way that no photovoltaic panels is even partly shaded at any point of the day.

  5. How much roof space does a photovoltaic system need?

    We recommend for MandoraSolar system per 1 KW/p 15 m² (160 Square feet). For a private house or a small shop/business usually a 2 to 5 KW/p MandoraSolar system will be the correct choice. The recommended area in this case is 30 m² to 60 m² (320 to 640 Square feet). MandoraSolar systems can be mounted on the roof of your building or on the ground. You can even use a piece of land which is not connected with the building or far away.

  6. Roof installation?

    Photovoltaic panels can be installed on the roof, on the side of a building, on the ground or on a pole. The most cost effective installation will usually be on a roof.

  7. Do installed solar panels have to face a southerly direction?

    In Cyprus facing south at the correct angle of elevation will provide the best performance (most KW´s per hour). However, solar panels can also be installed facing towards the east or west as long as proper considerations are made. Solar panels should never face north.

  8. What about cloudy days?

    Photovoltaic panels will generally produce electricity at a reduced rate under cloudy conditions. Severe clouds will interrupt the production of power.

  9. How do I know if a photovoltaic’s system is a good choice for me?

    Cyprus is beside Greece, Spain and Portugal a top-spot for photovoltaic systems in Europe. With around 340 sunny days per year in average photovoltaics in Cyprus are a brilliant choice.

  10. What are the maintenance requirements or other costs for a photovoltaic system?

    There is typically little or no maintenance required. You might consider a periodic inspection to ensure that the photovoltaic panels remain clear of leaves, dirt, bird droppings etc. Other than that there should be no maintenance required, unless there is any technical failure.

  11. What are solar inverters?

    A power inverter is a device that inverts DC (direct current) into AC (alternating current). In a photovoltaic installation, a power inverter is a centralized device that connects to and manages the performance of the photovoltaic array. It aggregates DC power coming from the photovoltaic panels or strings of photovoltaic panels and inverts the DC power into single phase or three phase AC power at the correct voltage for delivery into the user’s electrical system and additionally provides equipment protection and safety features.

  12. Will the photovoltaic system function as " backup" power when utility power is not available?

    MandoraSolar is an innovative photovoltaic systems which can automatically switch from on-grid (connected to EAC/AIK) or off-grid (stand alone) mode. MandoraSolar photovoltaic systems feed the power to loads, any surplus of power will be fed to the public EAC/AIK grid. At the same time it can charge the optional battery backup. If the photovoltaic panels can not produce enough power to supply your applicances, the other parts’ power will be taken from the public EAC/AIK grid.
    When the public EAC/AIK grid experiences an outage, MandoraSolar system will automatically switch to off-grid mode. If the generated power supply is sufficient for your loads, MandoraSolar system will charge the optional battery system with any surplus of electricity production. While there is no input from photovoltaic panels and the public EAC/AIK grid, it will use power from the optional battery system automatically.
    As soon as the public EAC/AIK grid is available again, the MandoraSolar photovoltaic system will switch back automatically to on-grid mode.

  13. How do photovoltaic panels stand up to hail, wind, hurricanes etc.?

    Photovoltaic panels themselves are built using tempered glass for durability and safety and are designed to withstand hail and strong winds. Depending on the wind- load requirements in your area, heavier mounting hardware may be required.

  14. Will photovoltaic panels damage my roof?

    Properly installed photovoltaic panels will not damage your roof. If your roof is near the end of its expected life, it might be a good idea to consider replacing the roof before adding photovoltaic panels, because removing and reinstalling the photovoltaics panels can add to the cost of a roof replacement.

  15. How long does it take to install a photovoltaic system?

    A typical residential roof installation can be completed in 3-4 days. The number of photovoltaic panels and type of installation will affect the installation process.

  16. How much will I save, how quickly will a system pay for itself?

    MandoraSolar photovoltaic systems usually amortise within 3 years only. Your MandoraSolar photovoltaics system will provide you with electric power typically for more than 25 years. Additionally you can sell your PV surplus to EAC/AIK.

  17. Does a photovoltaic system affect the resale value of my property?

    Yes it does – positively. Available real estate resale value data indicate that money spent on photovoltaic system installations is recoverable and may actually increase the value of the property beyond the amount spent.

  18. Does the net metering process cover both the gas and electric bill?

    Net metering will only cover the electricity portion of your utility bill.

  19. Is there a self-installation option for solar leading products?

    King Solar only provides residential solar solutions installed by our trained network of dealers.

  20. Can a residential solar system be attached onto a tile roof?

    Yes, your dealer will present a solution on installing a Solar leading system onto tile roofs in a seamless fashion. Please schedule a consultation with a Solar leading Dealer to find out more.

  21. Will I need to apply for any permits in order to install a solar system?

    Your dealer will handle all permitting issues related to installing a solar system on your property.

  22. How long does the entire process take from start to finish?

    From start to finish, the solar installation process will take anywhere from 3 to 6 months. The actual on-site installation, however, only takes a couple of days and will not inconvenience your lifestyle. The rest of this time is spent on waiting for state incentives and permitting to be approved. Our dealers are expertly trained at navigating the administration process to minimize the amount of delays.

  23. What type of maintenance is involved with a solar system?

    With a very few moving parts, a solar system is relatively maintenance free. An occasional cleaning of panels will ensure optimal performance.

  24. Are the panels fragile?

    No. While the panels are made of tempered glass, they’re quite strong. They passed hail tests, and they are tested against extreme weather conditions.

  25. How long will my King-Solar Solar system last?

    King-Solar Solar panels have a 25-year performance warranty – longer than almost anything else you can buy. The rest of the system has a 10-year warranty in most areas. Inverters can have warranties up to 10 years.
