SOLAR PV SYSTEMS
HR ENERGY SOLUTIONS
Herts Renewable Energy Solutions is committed to making solar more accessible and more attractive. We are a business for a purpose to play our role in protecting and saving the planet Earth. According to UK Renewable Energy Roadmap provided by the Department of Energy & Climate Control, Solar PV was included as one of the key renewable energy technologies that can help create a balanced UK energy mix.
Among the different systems using Renewable Energy Sources, Photo-voltaic is promising due to intrinsic qualities of the system itself, it has a very reduced service cost (the fuel is free of charge) & limited maintenance requirements. It is reliable since they do not have moving parts (useful life usually over 20 years), robust in design, noiseless and no emission of polluting material.
A photo-voltaic plant (PV) work on principle of Photoelectric effect through which some semiconductors suitably doped (generally Silicon) generate electricity when exposed to solar radiation. A solar PV transforms directly and instantaneously Solar Energy in to Electrical Energy without using any fuel. The annual electrical power output of a PV panel depends on the following factors:
Solar Radiation incident on the installation site
Inclination and orientation of the panels
Presence of shading / Shading Factor
Technical performance of plant components (mainly module and inverters)
Solar Panels reduce the amount of energy you buy from your energy supplier. The Feed in Tariff Scheme pays you for each kWh of energy you generate. During the day time when the solar panels are generating electricity, the power will automatically feed your home appliances. Any excess power which is to be used at home will be imported from the grid. The other case when the power produced by solar panels is in excess and not being used at home, the excess electricity will be exported back to the National Grid and you can earn extra income.
There is a common misconception that PV cells require direct sunlight, but in reality they don’t. They can work very well on cloudy days which makes them a great solution for European countries such as England.
For instance if we take a look at Germany which has the same Irradiance factor as United Kingdom. Germany has more installed solar power capacity than any other nation, at 38.5 (GW) of capacity – nearly half of Europe’s total 89 (GW) according to German Federal Network Agency.
Whereas if we look at the solar power in United Kingdom, by the end of 2014 there was almost 5 (GW) of solar photovoltaic panels installed, up from 2.8 GW at the end of 2013. Solar power almost doubled in 2014 with 650,000 installations ranging from solar farms to panels on homes, the Department of Energy and Climate Control figures showed. The government schemes and incentives on renewable technology is making these technologies more popular among people and encouraging them to be green.
Solar PV is great investment. Under the government’s Feed-in Tariff Scheme (FIT), you receive cash in return of generating your own electricity using renewable energy. If you are eligible to receive FIT you can benefit in 3 ways:
A set rate paid by the energy supplier for each unit / kWh you generate. This rate changes every year for new entrants to the scheme however once you join, it will continue on the same tariff for the next 20 years.
You are entitled to receive another 4.77p/kWh produced for each unit you export back to the grid when it is not used on your site or you also have the opportunity to opt out of this fixed price and try to negotiate a better rate with your electricity supplier.
Energy bill Savings
You will make major savings on your electricity bills. In many cases a profit as you will produce more energy than required most of the time. Usually between 9am – 4pm when your house is not occupied. The excess electricity will be bought off you by your Energy Supplier.
You can use the Solar Energy Calculator which estimates the savings which you can make by installing a solar PV system and the payment you could receive from the FIT scheme.
