A solar panel or photovoltaic module/panel, utilizes the photons from natural sunlight to create electricity for residential or commercial purposes. Solar panel installations typically use more than one solar panel but a series of them to generate the required amount of power. Photovoltaic cells connected together in series this way are referred to as a photovoltaic array. A photovoltaic array will usually consist of the solar panels, batteries, wiring and an inverter. Solar panel prices are as variable as the configuration options available. Solar panel systems are extremely cost effective in parts of the world that benefit from year round sun such as Africa, the Caribbean and Asia and are often used in these locations to power water heating systems. Solar panels do vary in their efficiency and it is important to take time to choose wisely and research your purchase properly.

How a Solar Panel Works
A photovoltaic cell operates according to the photovoltaic effect. The photovoltaic effect converts solar radiation into direct current electricity (DC Voltage). Semiconductors that display the photovoltaic effect, such as crystaline silicone, are used in wafer from to create the photovoltaic modules or solar panels. Diodes are incorporated into photovoltaic cell design to avoid overheating and solar panel installers try to include some kind of ventilation to assist with this issue as solar panels do not have any inbuilt mechanism to reduce temperature.
Photovoltaic Cell Suppliers from the UK
Comparing photovoltaic cell suppliers from the UK must be done with regard for their experience in configuring solar panel systems for clients. Having a suitably qualified service and installation team will make life easier and avoid unnecessary complications further down the line. Photovoltaic cell suppliers from the UK should also be able to offer a service contract for any servicing and repair jobs on the system that may be needed. Recommendations should be available from past and present customers regarding the level of service rendered on certain projects. Find out if the supplier is an authorized sales and service representative of the manufacturer as that will secure better prices and service personnel training.
Solar Panel Prices
Solar panel prices in the UK will depend on the power output requirements. Photovoltaic cells connected in series generate a desired electrical voltage and parallel connection provides a desired electric current. Basic solar panel prices in the can start as low as £700 for a 150 watt solar panel kit and small solar panel kits are available from maplins. Larger solar panel prices can run into many thousands of pounds for more complex configurations.
