Commercial Technical Services is committed to staying at the forefront of new technologies. So when the concept of Solar Powered communal TV systems became a practicality for buildings without a landlords supply, CTS was one of the first installers to offer this to clients.

Several hundred installs later, it seemed a natural progression for CTS to build on this experience and utilise our skills in Electrical Contracting and Working at Heights to pursue the latest innovations in Solar Photovoltaic energy generation to produce clean energy for domestic and commercial properties.

The engine of a solar PV system are its photovoltaic cells, these cells are capable of converting light into an electric current. The electricity generated by solar panels is a DC 'direct current', whereas, the "mains" electricity we all use is AC - 'alternating current'. In order to utilise the electricity from the panels it must be converted from DC to AC. An additional device called an Inverter undertakes this role along with constantly monitoring the electricity coming in from the national grid, and then modifying the DC electricity generated by the solar panels to match it perfectly.

The electricity generated by the solar PV system is automatically used directly to power a property with any excess being automatically sold straight back to the supplier. Any shortfall of power, such as peak use times or at night, is topped up by the supplier. Solar PV operates on light intensity, not heat, so even if the day seems cold, if there is light, the system will be generating electricity, PV systems will therefore generate electricity all year round.

It is a surprise to most people to discover that the UK climate provides perfect conditions for Photovoltaic Solar generation. Extremes of tempreture effect the efficiency and the lifespan of the panels making the temperate weather found in England, France, Germany etc ideal. However, light intensity changes with the seasons, therefore most electricity will be generated in the summer with the least in the winter.

Over the course of a year, a solar photovoltaic system will save you money by reducing your electricity bill, and will earn you at least 44p for every unit of electricity that you generate on systems under 4kWp.

This revenue is known as the Feed in Tariff (FIT), which became available in Great Britain on 1st April 2010. Under this scheme energy suppliers have to make regular payments to consumers who generate their own electricity from renewable or low carbon sources. This means the initial capital outlay of purchasing a solar PV system is reclaimed much quicker.

The feed-in tariff only pays this increased rate for a set number of years, which for photovoltaic's (PV) has been set at 25 years and is index linked. To encourage early adopters, the FIT is set at 43.3p per unit for 25 years for sites registered before 31st March 2012.

Feed-in tariff rates will be paid for each unit of electricity generated even if it is used by the consumer. As well as this, any excess electricity, it can be exported back to the grid earning an extra 3.1p/kWh.

Commercial Technical Services is accredited as an installer with the Microgeneration Certification Scheme, the regulatory body for the renewable energy sector. Only companies registered through this scheme can apply for Feed in Tariffs for their installations. The MCS scheme also requires that only equipment tested and accredited to their high standards can be used in installations benefiting from FIT's.

Whether you are looking for a system to fit on a commercial building, domestic property or an RSL looking for a complete asset upgrade CTS can design, supply and arrange finance to your requirements.
