PV Panels

PV Panels

Quite possibly the most important piece of the solar installation, the PV panels are what produces the power you need. Ensuring you go with good quality panels that produce power efficiently will ensure that you have get most return on investment from your solar system, meaning more power produced. Our panels are the most efficient on the market and will ensure excellent power production rates.

PV Solar Panels

What is a PV Solar Panel?

Photovoltaics is used to describe the technique of converting solar energy directly into electrical energy. This so-called photovoltaic effect, generated from light power, was discovered by Alexander Becquerel in 1839.

The term "photovoltaic" originates from the Ancient Greek word "phos", meaning light, and the SI unit for electrical voltage (volt).

When photons hit a solar cell, electrons are stimulated to migrate and an electrical direct current is produced between the side turned towards the light and the side turned away from the light. Electrical current flows as soon as the electrical circuit is closed.

Types of PV Solar Panels

There are 3 basic types of construction of PV Solar Panels constructed of silicon.

Monocrystalline cells are cut from a single crystal of silicon and are effectively a slice from a crystal.

In appearance, it will have a smooth texture and you will be able to see the thickness of the slice.

These are generally the most efficient and the most expensive to produce. They are also rigid and must be mounted in a rigid frame to protect them.

Polycrystalline (or Multicrystalline) cells are effectively a slice cut from a block of silicon, consisting of a large number of crystals.

They have a speckled reflective appearance and again you can you see the thickness of the slice.

These cells are generally slightly less efficient and slightly less expensive than monocrystalline cells and again need to be mounted in a rigid frame.

Amorphous cells are manufactured by placing a thin film of amorphous (non crystalline) silicon onto a wide choice of surfaces. These are the least efficient and least expensive to produce of the three types. Due to the amorphous nature of the thin layer, it is flexible, and if manufactured on a flexible surface, the whole solar panel can be flexible.

One characteristic of amorphous solar cells is that their power output reduces over time, particularly during the first few months, after which time they are basically stable. The quoted output of an amorphous panel should be that produced after this stabilisation.

ReneSola
As a specialist solar company it’s important to use only high quality, high efficiency PV panels. We have chosen to use ReneSola PV panels because they offer outstanding performance and reliability. solar manufacturers are tier one. ReneSola can be found in projects ranging in size from a few kilowatts to multi-megawatts in markets around the world, including the United States, Germany, Italy, Belgium, China, Greece, Spain, Australia and New Zealand. The new, breakthrough, Virtus®II solar panel is an ingenious combination of the high quality and efficiency of Monocrystalline modules, with the lower cost of Multicrystalline modules. The outcome is significantly increased cell efficiency at an affordable price. The company’s innovative Virtus® A ++ wafers achieve a 4% higher power output than many of its competitors. As well as outstanding performance, ReneSola panels offer peace of mind and carry an insurance backed warranty In addition to the comprehensive 25 year linear power warranty terms. ReneSola has purchased product warranty insurance to “back‐stop” the product warranty.

We currently have offices and installers through all main centres in New Zealand. Please contact the head office for your initial enquiry and we will put you in touch with our local representative. Save Money Each year, power prices increase at a rate of around 7.5% on average. Combined with a big drop in price, solar is now a financially sound option. By going solar, you can lock in lower rates for power. While the cost of electricity increases with time, your solar PV will deliver more and more savings as you tap into the free power of Northland’s sun. Increased property value The electricity savings from solar panels translate directly into an increased home resale value. The U.S. Department of Housing and Urban Development
