How much do Solar Panels Cost?
Solar panels are organized into photovoltaic arrays to combine and harness the solar radiation from the sun. This radiation (photons) is converted into DC current for a variety of applications. Solar panels utilize the photovoltaic effect of certain semiconductors and when organized into photovoltaic arrays are connected in series to achieve a desired output voltage and in parallel for a specific current. Solar panel cost will vary according to the size of the system and its intended use. Solar panel prices will also be governed by the manufacturer of the system components and the solar system supplier.
Solar Panel Prices
Solar panel prices are calculated by the size and power output of the photovoltaic array (PV) and the solar panel arrangement specification, required to generate the required power output. The more good sunlight hours available per day, the lower the power output solar panel required to achieve a certain power output over a particular length of time. So, it would follow that the cost of a solar panel system in hot and sunny countries would be lower because more sunlight is available per day to fuel the system and provide power over a longer period of time. Grid-connected PV solar panel systems are the simplest types of solar panel systems and cost between £5000 and £7000 in the UK including installation.
Commercial Solar Panel System Prices
Commercial solar panel system prices will vary according to the size of the installation and the purpose of the installation and must be a custom design. A common application of commercial solar panel systems is to provide heating for multiple dwellings. Apartment buildings can be fitted with a shared solar panel heating system which serves all of the apartments and is more practical than each apartment having its own solar panel system as there is a common roof. Commercial offices can also utilize solar panels in the provision of alternative and sustainable energy. Swimming pools can also be heated by solar panels and system designs will vary depending on whether the swimming pool is outside or inside.
Residential Solar Panel Cost
In February 2010 the UK government announced that it would give money to households who have fitted certified thermal Solar Thermal Hot Water Systems which makes the cost of solar heating systems even cheaper. The average cost of solar panels for residential uses is around £5000 and will also depend on which way the roof of the house is facing.
