Grid Connected Photovoltaic (PV) System:

SUNSET® Grid-Connected Systems:

On the following pages you will find an overview of our standard grid-connected systems for power production of up to 5 kWp. The components used in these systems are described individually and in detail. Large-scale systems are either compiled from several standard systems or are designed to the customer's individual wishes. All systems offered are built with high-quality components, as demonstrated by thousands of applications. The components are optimised to match perfectly, thus ensuring ideal system efficiency and high power production efficiency.

Since the end of 2003 we deliver grid-connected systems with SUNSET AS and TWIN solar generators with pre-selected stringing. An optimum wiring of the solar generators leads to a maximum result. We offer this extra service automatically and without surcharge.

Over many years of experience in the Photovoltaic sector, SUNSET® has designed and manufactured complete PV systems suitable for domestic, commercial, public, agricultural and field installed applications.

The key factor for a high efficient Photovoltaic system, is the professional planning and calculation of all relevant components. We have automated this process over the past years and we are able to complete your customised calculations very quickly. All system components will be power matched and tested before dispatched from our manufacturing bases. This will guaranty the best system performance and efficiency based on your location and roof orientation! This process is unique and SUNSET® is very proud of this know-how.

SUNSET has a wide range of grid-connected systems on offer. We can offer you the appropriate, yield optimised, system, for all possible appliances. Solar generators are divided into three cell types: single-crystal, polycrystalline and amorphous. In order to simplify the different Photovoltaic technologies, we will introduce each system step by step.

Solar Material:

Single-Crystal Solar Cell:

High-purity semi-conducting material is needed to produce single-crystal silicon cells. Single-crystal silicon ingots are drawn out of a silicon melt and are subsequently cut to thin wafers. This complex production process ensures relatively high efficiency. Single-crystal cells also guarantee long-term stability of power output. The cells' power output remains almost level throughout their working life. Single crystal cells supply a higher energy yield than other cell types, especially under diffuse light conditions (e.g. overcast sky).

 

 

 

Polycrystalline Solar Cell:

The production of polycrystalline silicon cells is more cost-efficient. Hereby the liquid silicon is poured into blocks and subsequently cut into wafers. As the block solidifies crystal structures in varying sizes form. The variations of the crystal structure result in a slightly lower cell efficiency. Due to their square shape the solar cells make a better use of the space available in solar generators. Polycrystalline solar generators can therefore almost achieve the same area efficiency of single-crystal modules. The amorphous cells have improved in cost and efficiency over the last 5 years and took advantage over the polycrystalline cells. However we can deliver polycrystalline cells on request. Please contact us for further information.

  

Amorphous Solar Cell:

Solar cells are called amorphous or thin film cells if a silicon film is applied to glass or to some other substrate. The film is les than 1 lam thick (a humane hair is 50 - 100 pm thick), so that the production costs are reduced by the lower material costs alone. New production processes have increase considerably the efficiency of amorphous silicon. Besides many other smaller technical specialties, such as higher output at high temperatures, bypass diodes have become obsolete. The omission of bypass diodes enable modern amorphous solar modules to almost reach the same average yearly yield of other cell types but for much less money!
