Solar Photovoltaic cells (Solar PV) are effectively panels that absorb the sun’s light (which is actually made of many tiny units of energy) and convert it via a sophisticated system of silicon wafers into an electrical current that can then be used to power up your home, office or electrical appliances directly. Although not yet highly visible in the UK domestic market, solar PV panels are already very common in calculators and watches (albeit in a much smaller size). The larger solar panels are getting increasingly more efficient and are now used to generate power for private homes, large office buildings and other commercial installations.
Solar Photovoltaic and Planning Issues
One can install solar photovoltaic panels on the roof of their home as well as along one of the outer walls or as standalone units. Before setting off on the installation process, it is essential to check with the local authority regarding planning restrictions. Most local authorities in England allow solar PV panels to be installed on residential roofs and as standalone cells as long as certain criteria are met (mainly that the panels are not attached onto listed buildings or within conservation zones). Wales, Scotland and Northern Ireland, however, are still working out their local legislation. For residents of these areas it is therefore advisable to consult the local planning authorities before installing the solar systems.
Why Use Solar Photovoltaics?
There are several good reasons to use solar PV cells. One important benefit is the money saved on electrical bills. Another important benefit is the reduction in carbon emissions thanks to using clean energy. Solar photovoltaic cells cut around 1.2 tonnes of carbon dioxide emissions every year. Since the user generates the electricity directly from the sun, they are not dependent on the national grid, making them less prone to power cuts. Although solar power is effective in its own right, solar panels are highly appropriate for remote locations where the grid has no coverage (such as remote farms or research facilities).
How is Solar Photovoltaic Cell Installed?
The best way to install solar photovoltaic panels is to hire a professional installation crew. Professional solar PV cell installers should be certified by the Low Carbon Buildings Programme. It is important to note that there are good reasons one should not attempt to do the installation as a DIY project. Solar PV cells tend to be very heavy and, for roof installations, involve a support system that must be constructed and attached before any solar photovoltaic cell can be mounted. The installer will know the local electrical codes and safety regulations and will make sure that the solar photovoltaic grid or standalone units are code compliant.
With the increasing public awareness to global warming and climate change, there is substantially more focus placed on finding energy generation options that are not reliant upon fossil fuels. Of the alternative energy options currently available (wave, wind, hydrogen, solar, nuclear), solar power is considered to be the most cost effective and with solar panels dropping in price due to competition, this technology is likely to become ever more popular.

At home or on the road, you’ll have all the power you need with a Sunforce solar panel! Sunforce features the latest solar power technology to deliver longer-lasting, more consistent power! The perfect green power solution for home, RV, emergencies, camping, boating and more, these solar panels yield more energy per kilowatt than competing models. Just attach the solar panel to a 12V battery and let the magic happen. The secret is American made Copper Indium Gallium diSelenide Solar cell (CIGS) technology that provides better performance in cloudy and low light conditions. Also features high-quality diode-protected junction box for easy connections to charge controllers, durable solid aluminum frame and tempered glass for durability. 31 x 43-1/8 x 1-1/2. 25-year limited warranty. (CIGS) Provides stable power at a lower cost and does not degrade as quickly as other solar technologies. It creates more energy from an equal amount of sunlight than other technologies because of its high conversion efficiency.
These panels cleverly convert the suns light into electricity. The cells are usually made up of layers of a semiconductor called Silicon. When exposed to light a DC electrical charge is generated. When numerous cells are banked together they can produce large amounts of electricity. These cells can be used to power many electrical devices from calculators to your home appliances. The sunnier the position the more electricity that can be generated.
This often, but not always, means positioning the panels on a south facing roof. If the roof is flat the panels can be mounted on frames that hold the panels at the optimum angle.
When connected to the national grid a property can benefit from reduced electricity bills and can even export electricity to the national grid.
The panels tend to cost somewhere between £5000 to £7500 per kW, depending on the required specification and particular project.
Are Solar PV panels right for my property?
If specified properly, installing Solar PV WILL reduce your electricity bills. For roof mounted panels, having a south facing roof is useful. However, depending on the roof angle, panels can function properly facing South West to South East. They still benefit from 95% of the suns radiation.
The panels can be sized in a number of ways, one method is to match the capacity to the minimum load on the property, so if the property typically uses 1kW, install 1kW of panels. This means that on the sunniest day every bit of electricity being generated is being used. Alternatively, you can install a much larger capacity and sell the excess electricity back to the national grid. The rates the electricity companies will pay for this electricity is becoming more competitive everyday.
Are there any grants?
There are many streams of grant funding depending on your particular project. For domestic properties any one can get a grant if they use a certified BRE installer. The grant is up to £2500 (£2000 per kW installed).
For non profit organisation there are grants that may pay for the whole installation. Commercial businesses should contact there local authority to see if there are any local funding streams.
However, even without a grant a Solar PV system is a good investment.
Will this type of solar panel pay for itself?
In short the answer to this question is YES. The government grants in the UK have reduced the payback massively. A more detailed answer would need to look at exactly how payback is to be measured. The environmental payback is extremely quick, perhaps even 6 months? With regard to financial payback the calculation becomes more complex, let’s assume the following:
- Electricity prices continues to rise as they have over recent years.
- The system adds 50% of it’s installation cost to your homes value.
- You export surplus electricity to the national grid on a typical export tariff.
Given these, not unreasonable, assumptions, a system could payback within 10 years. After 20 years the system would have paid for itself twice over.

if some one can tell me the method of making cheap solar panel he should reply me for help me
The people that are claiming its difficult are refering to building one from scrap. I recently put up a few small ones and will be covering my roof next summer because I’m very satisfied. I used the designs from http://www.earth4power.biz and it was fairly simple. Basically it gives you sources for all the cheapest parts and an easy design, you assemble and save a ton of money.
