About Solar

WHAT IS SOLAR?

The sun provides massive amounts of renewable energy that can be harnessed to provide us with heat and electricity, the two key requirements for running the modern world. The amount of solar energy that falls on the Earth in just one hour is enough to power the world for a whole year.

By using renewable energy sources such a Solar Thermal, Solar PV reliance on fossil fuels can be minimised, thus directly reducing CO2 emissions.

In the average household, water heating accounts for around 30% of CO2 emissions. Installing a solar water heater can provide between 50-90% of a household’s hot water heating energy needs, and reduce CO2 emissions by more than 20%. If offsetting electricity from non-renewable sources, installing an Apricus AP-30 solar collector can save around 1500kg / 3300lbs of CO2 each year. That is roughly equivalent to planting more than 380 urban trees, or each year driving 10,000 km or 6250 fewer miles in a mid sized modern petrol (gasoline) car. A solar thermal collector is therefore an excellent way to reduce your household’s carbon footprint.

WHY SOLAR?

What Can Solar Hot Water Do For Me?

Installing a solar hot water system using an Apricus solar collector, is a simple upgrade that homeowners can make to protect themselves from rising energy costs.

A GREENTEK solar hot water system can provide between 50-90% of a households annual domestic hot water FREE from the sun making it one of the most effective ways to save money on your energy bill and also reduce your household’s carbon footprint.

Solar For Your Business

Solar hot water is a simple upgrade that businesses can make to protect themselves from rising energy costs. A GREENTEK system can provide between 50-90% of a businesses annual domestic hot water FREE from the sun making it one of the most effective ways to save money on your energy bill and also reduce your buildings’s carbon footprint.

HOW SOLAR WORKS?

System Components
A commercial solar system normally includes the following components:

  1. Solar Hot Water Collectors (Evacuated Tube or Flat Plate)
  2. Circulation pump
  3. Controller
  4. Hot Water Storage Tank(s)
  5. Backup Energy Source
Operation
  1. Energy in sunlight is absorbed by the solar collector, heating up the liquid inside.
  2. The heated liquid is transferred back to the hot water tank by the circulation pump.
  3. Throughout the day solar energy gradually raises the temperature in the hot water tank.
  4. If the solar energy is not sufficient to provide hot enough water, a backup energy source (electricity, gas, oil etc) is used to further heat the water.

The same basic system design shown in the residential system below is applicable to commercial projects, just with more collectors, more powerful circulation pump and more hot water storage capacity. Commercial solar hot water systems are normally configured to provide “pre-heated” hot water to the existing boiler equipment.
