On average, every square meter of Earth’s surface receives 164 watts of solar energy. In other words, you could stand a really powerful (150 watt) table lamp on every square meter of Earth’s surface and light up the whole planet with the Sun’s energy! Or, to put it another way, if we covered just one percent of the Sahara desert with solar panels, we could generate enough electricity to power the whole world. That’s the good thing about solar power: there’s an awful lot of it—much more than we could ever use.But the downside is the energy the Sun sends out arrives on Earth as a mixture of light and heat—neither of which we can use directly to run a television or a car. We have to find some way of converting solar energy into other forms of energy we can use more easily, such as electricity. And that’s exactly what solar panels do.GreenEarth Solar Kits include everything needed for a straightforward installation using tried and tested products. They are high performance grid connected solar power kit systems and are ideally suited for installation on existing roofs of homes and commercial buildings. All products are specifically selected for their quality, performance, simplicity and efficiency.

SOLAR PV F A Q
Q: What is PV or photovoltaics?A: What do we mean by photovoltaics? The word itself helps to explain how photovoltaic (PV) or solar electric technologies work. First used in about 1890, the word has two parts: photo, a stem derived from the Greek phos, which means light, and volt, a measurement unit named for Alessandro Volta (1745-1827), a pioneer in the study of electricity. So, photovoltaics could literally be translated as light-electricity. And that is just what photovoltaic materials and devices do; they convert light energy to electricity, as Alexandre-Edmond Becquerel and others discovered in the 19th Century.
Q: What are the components of a photovoltaic (PV) system?
A: A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; a charge regulator or controller for a stand-alone system; an inverter for converting alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.
Q: How does the system work?
A: Daylight hits the photovoltaic cells and is converted to clean electricity. The inverter converts the electricity from direct to alternating current, for use in the home. When the solar energy system is producing more power than is needed it is exported to the grid. At night, power is imported from the grid in the normal way.
Q: What is the difference between a kilowatt (kW) and a unit or a kilowatt hour ( kWh)?
A: A kW is a thousand watts and a unit of power. It measures the rate of energy conversion. A kWh is the amount of work done, or energy used, when a kW of power works for one hour.Q: Do Solar Panels create energy?A: A basic tenet of thermodynamics is that energy is never actually created only converted; solar panels convert solar energy into electricity rather than just creating it.
Q: Does the system need batteries?
A: No, the system is connected to the national grid. In the night, when the cells are not generating energy, electricity is not pushed into the grid. The electricity generated during the day is sold back to the utility company.
Batteries are only required if you want a truly off-grid solution and independence from any power cuts that might occur. They are also required if you own a property which is not attached to the grid in order that power produced during the day can be stored for use in the evening. Batteries add significant costs to a solar system so are normally only never offered with a grid tied solar PV system.
Q: How can I connect my system to the grid?
A: Connecting a PV system to the distribution network will require permission from your energy producer. Our licensed L2 ASP will help you to acquire this permission and connect your system to the grid.
Q: How long will it take to install my system?
A: PV systems can be installed and ready to produce electricty in 8-10 weeks from the time the design has been agreed.
Q: How big a solar energy system do I need?
A: The size of solar system you need depends on several factors such as how much electricity you use, how much sunshine is available where you are, the size of your roof, and how much you’re willing to invest. After talking through your exact needs we will be well placed to recommend the size of system you use.
Q: Will I ever have to go without power?
A: Your home will still be connected to the National grid. The solar power output will be connected to the grid with a different line, and will have no connection to your house electric line. As a result, you will never go without power if there is no power cut from the grid.
