  • What is Solar PV?
    PV is the shortened form of the word Photovoltaic. It is the process of converting sunlight into direct energy using conductor based technology.
  • How does Solar PV work?
    When sunlight makes contact with a solar photovoltaic (PV) panel, direct current is produced, with the inverter transforming this current from Direct Current (DC) to 240v alternating current (AC). This can be generated for home use or transferred to the grid
  • What is the difference between polycrystalline and monocrystalline panels?
    Monocrystalline and polycrystalline serve the same function in the overall solar PV system and possess most features in common. They both absorb energy from the sun and turn it into electricity, they are both made from silicon and they are both durable. However, there are slight differences. The main difference between the two is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from many silicon fragments melted together.
  • Is there a difference between the solar hot water system and the solar PV system?
    Yes, there is. The solar hot water system simply uses the sun to directly heat water. A solar PV system converts sunlight into electricity for home use or to be fed into the electricity grid. The heat output of the sun is not crucial for solar PV systems, but the amount of sunlight available definitely is.
  • Since when has PV been around?
    Solar PV (photovoltaic) was first discovered in 1839 by French scientist Edmond Becquerel. Scientists made solar cells of selenium in the 1880s. Subsequently, modern PV technologies were developed at Bell Labs and RCA Labs in the mid-1950s.
  • Can I heat my water with solar panels?
    No, you cannot, these solar panels are functional for electricity only. You need a thermal solar system to heat water.
  • How can electricity get stored for use after the sun goes down?
    Generally, grid-connect systems direct excess electricity produced during the day back into the local electricity grid, so there is no on-site storage as such. You then receive credit for any power that you put back into the grid. At night time, you automatically use electricity straight from the grid. Off-grid systems store energy produced during the day in deep cycle batteries for use as required.
  • How do my panels get powered on a cloudy day?
    On sunny days the panels obtain the best possible electricity collection but on cloudy days the panels will not absorb the same amount. The panels would only accumulate about half the output that would be acquired on a sunny day. If the electricity for a cloudy day is not enough to cover the household requirements, the system will utilize power directly from the grid. The performance of the solar PV system is affected by cloud cover. When there is not enough light to produce electricity, you will use electricity from the grid.
  • How do I keep power supply during a blackout?
    You would need a battery backup.
  • Is it possible to retrofit battery backup into a Solar PV system?
    Yes, battery backup systems require additional components such as a solar regulator, batteries, and an inverter.
  • How heavy would the solar system be on my roof?
    Solar systems are light weight but with very strong Aluminium mounting frames, while distributing a total weight of just 8 to 12 kg per square meter.
  • Is my property suitable for a solar system?
    There several aspects to consider when determining if your home is a good solar site, such as available space, orientation, shadows on the space available and your current electricity consumption. The perfect site is one with adequate unshaded roof space.
  • How much will a solar power system cost?
    Please get in contact, and our team will put together a proposal for a system that is suited to your property's needs.
  • What is the feed-in tariff?
    Feed-in tariffs are fixed electricity rates that are paid to renewable energy producers for every kilowatt-hour of electricity your solar PV system feeds into the grid.
