Greenshop Solar is fully accredited under the Microgeneration Certification Scheme (MCS) to install solar thermal panels, solar photovoltaic panels (PV panels) and wind turbine systems.

This means that all solar thermal, solar photovoltaic and wind generator systems that we design, supply and install, fully comply with a stringent industry standard.

Systems installed comply with the Feed in Tariff (FiT) and the coming Renewable Heat Incentive (RHI) requirements.  

Greenshop Solar also distribute solar collectors and accessories other to installers.  

Generating Heat and Power Using Solar Energy

Greenshop Solar sells and installs renewable energy systems. We are specialists in solar thermal systems providing hot water and optional assistance to space heating using Consolar thermal stores, as well as photovoltaic energy generation systems. We install in Gloucestershire, Wiltshire, Worcestershire and surrounding counties.

We are also UK distributors for Consolar state of the art thermal stores and solar collectors. The solar panels available can be evacuated tube or flat plate collectors. The flat plate collectors can be installed "in roof" or 'on roof" as required. The Tubo evacuated tube collectors are neat and slim without the unsightly bulky manifold, a characteristic of so many glass tube collectors. 

Thermal stores allow heat from solar and/or wood boilers to be saved for later use. eg. the solar energy harvested during the day can deliver heat in the evening and the following morning, negating the need to use the main heating system. This is ideal for low temperature heating systems like under floor heating. The systems are especially suitable for low energy buildings giving control over heat energy supply as required.

PV

The Future for PV is looking even better now the cost of the panels is lower, the cost has been dropping steadily over the recent years. The Feed in Tariff (FiT) started in 2009 at 41p/kwhr and with a 4kw peak system costing around £18,000 the return in investment was between 8% and 10%. Three years on and the price has dropped by 50%, the FiT has dropped the same and the return is still as good, despite the roller coaster ride that everybody has had during this period.

PV is still a good investment, from the FiT alone, with a 4kw peak system costing between £8,000 and £10,000, with 21p/kwhr payment a return on investment of 6-10% can be achieved. In addition to this if you use the power whilst the system is generating it saves importing energy, save money and carbon emissions.

The UK achieved over 1Gigawatt peak of generating capacity in January this year, and this is rising fast.

If the building has a PV system already installed additional panels can be added if space is available, these panels will only attract the FiT rate applicable at the time of installation, not the rate of the original system.

If your concern is maximising your use of the solar energy you can install a different inverter with batteries that will store the solar energy harvested in the day and supply it for use during the darker hours.

Another issue is energy security, when the grid electricity supply fails the PV system shuts down, an alternative is a different inverter and batteries that act as a backup supply. The length of time the backup supply will last is dependent on the number and size of the batteries. It is important to secure a supply for the heating controls, the fridge and freezer and lights. If these continue in times of power cuts life is not to difficult.

One new hurdle that owners of new systems now have to achieve is that the building that is connected to the system must be reasonably energy efficient, it must achieve a “Energy Performance Certificate” (EPC) level “D” or above. This can already be met by about half of the homes in the UK, those that can’t will be required to upgrade before they register for the FiT to get the full tariff or accept a lower payment level. The PV will help towards that EPC rating.

As well as domestic systems of all sizes, we also install larger systems up to 50kwp. Any of these systems can be building mounted on the roof, ground mounted fixed or tracking. A tracker, whilst being most expensive, will produce about 30% more energy by tracking the sun across the sky, it is always seeking the highest energy output. 

Wind Power 

Rural and commercial sites, houses, farms and businesses, if they have a good wind resource can benefit from the power a wind turbine can produce, saving them money on energy bills and helping to reduce their carbon footprint. To ensure that the turbine will be a good investment we suggest monitoring the prospective site before making the major investment in the turbine. We can do this as the first stage of the process using a "Power Predictor", from the results we can predict the return on investment. Installing a wind generator can also contribute to energy security by combining with PV and Backup systems. We install wind turbines up to 20kw
