Cost of Photovoltaic Solar Panels

Photovoltaic panels have revolutionized the idea of renewable energy by harnessing the photons from solar radiation and generating usable electricity for a variety of purposes. With no harmful impact on the environment or any by products requiring waste management, pv solar panel technology is a promising alternative power option. The only draw back of photovoltaic panels is the cost. The cost of photovoltaic panel systems in the UK has proven to be too expensive for most households and businesses to consider. Although the energy savings can be huge in the long term, the initial cost of purchasing and installing photovoltaic solar panel systems, has not made it a priority to most households and businesses. The market is changing and now it is possible to find affordable solutions and to compare solar panel prices from certified industry suppliers. More government intervention could make the switch to photovoltaic solar systems easier and rebate systems have started in the UK, albeit in a small way.

A Photovoltaic Array

The configuration of several solar or photovoltaic panels will be determined by the required Kilowatts per hour of the installation site and the available ?sun hours? per day of the location. Available sun hours per day are calculated by working out how many hours of sunlight produce usable solar energy for a desired output of a photovoltaic panel system over a particular time frame, per area or geographical location. Photovoltaic panels do not require any mechanical parts, make no noise and have zero emissions, making them an excellent choice for a renewable energy source.

Photovoltaic Configuration and Cost

The cost of a photovoltaic solar panel system will depend on the power output requirements and the geographical location of the installation. For example, 10 hours of sunlight in Mombasa, Kenya, may produce 8 hours of usable solar energy for photovoltaic cells to produce a desired output over a 24 hour period. This would provide a value called ?insolation? and would be an insolation value of 8 or 8 ?sun hours? for Mombasa. The same power output requirements for Stockholm in Sweden during the month of January may produce an insolation value of 2. This would mean that more powerful (and more expensive) photovoltaic panels would be required to generate the same power output as a Mombasa installation, over the same time frame. When several photovoltaic panels are configured together they are referred to as a photovoltaic array.

Photovoltaic Panels Cost Considerations

Before deciding on the configuration of photovoltaic solar panel system, it is advisable to maximize energy efficiencies by cutting out wasteful practices within the current power consumption model to ensure the maximum benefits of the photovoltaic panel system. Photovoltaic panel costs can start from as little as £30 for a simple, low power output to recharge a mobile phone, right up to and above £30,000 for a residential or commercial photovoltaic system used for powering heating or electricity systems.

Cheap Solar Panels

Solar panel technology has been a successful way of producing power using energy that does not impact on the environment and has long term cost benefits. Using the photovoltaic effect of certain materials solar panels are able to harness solar radiation and convert it into usable power. Cheap solar panels are now available across the UK and around the world for residential and commercial uses. Solar panel technology offers a great clean way to provide alternative energy sources, but due to the low short term profitability and lack of government investment, solar power systems have remained too expensive for many households to comfortably afford.

Photovoltaic Array

Solar panels are arranged into photovoltaic arrays in a configuration to produce the required amount of power and must be placed at particular angles to achieve the maximum solar energy extraction. Many commercial photovoltaic (PV) solar panel systems are able to track the movement of the sun to absorb the maximum amount of photons during daylight hours. Photovoltaic arrays utilize materials such as mono crystalline silicone and cadmium telluride that act as semiconductors within the solar panels.

The Best Solar Panels

Cheap solar panels may not necessarily be the best choice of solar panel for a particular installation. Solar panels offer a considerable energy cost saving in the long term if the right specification of pv solar panel system is chosen. Buying cheap alternative systems on price alone may not achieve the desired results and could become a redundant system and a waste of money. Using a reputable supplier is the best way to find a reliable solar panel system for the cheapest price.

Cheap Solar Panel Suppliers

Cheap solar panels can be found by purchasing used solar panels or if they are new and still cheap, details of the warranty need to be confirmed. A cheap solar panel could become expensive if the warranty demands that the purchaser must arrange shipment to and from their premises in the case of a faulty unit. Cheap solar panel suppliers should offer a warranty that includes the collection of faulty units and a replacement if possible. When considering on buying a cheap solar panel system from a supplier one should find a supplier that can also install the system correctly. Be sure to seek references of past work carried out and feel free to make contact with the past customers for feedback regarding the service that they received and their satisfaction level.

  4. Price performance ratio of photovoltaic prices. Surely it can not always assume that photovoltaic prices implies an ever higher quality and longer life with better value for money. However, it should not be aware of low solar prices, but rather just deal with quality and durability of the modules. Without this knowledge is of course difficult, and therefore good counseling is advisable for such a complex product. A good advice is the basis for good decision, which is also useful in the long run. Especially given the large amount of investment for a solar power compares different offers.

  9. Impressive post! I read a related report in a few days ago. The report indicates that the median installed price of PV systems installed in 2011 was $6.10 per watt (W) for residential and small commercial systems smaller than 10 kilowatts (kW) in size and was $4.90/W for larger commercial systems of 100 kW or more in size. Utility-sector PV systems larger than 2,000 kW in size averaged $3.40/W in 2011.
