The internet is full of companies offering equipment at bargain prices but in the renewable energy field, knowledge and experience are where the customer can find true value.
Blue Sky Power are members REA (Renewable Energy Association) We are Microgeneration Certification Scheme (MCS) approved and are constantly updating levels of employee training to keep pace with this fast moving industry.
That is where we at Blue Sky Power differ. We will only provide information that is suitable to your situation and not one to mirror a stock list or sales target. Our engineers are on hand to answer any questions you may have regarding installation problems and related queries.
We supply (and if desired install) fully automatic dual axis solar tracking arrays, anywhere in the United Kingdom. Whether for your home, farm, off grid property or business premises.
We believe in choice and aim for the highest levels of service and customer satisfaction. So if you have a specific problem in mind or just require general information, our help and advice is ready and waiting.

clear information on the systems planned and their performance
acceptable sales and marketing techniques
arrangements for installing and connecting the system
the selection and quality of goods supplied
details of the conditions of business that apply
the standard of any installation and other on-site work
guarantees, and any maintenance and after-sales services needed
what action will be taken to deal with any problems, and
arrangements for monitoring and continuously improving the Code.
On 1st April 2010 the government introduced the most important development in renewable energy industry for many years. The new Feed In Tariff (FIT) was designed to encourage the development of a low carbon economy.
There are two types of tariff: The Generation Tariff and The Export Tariff
GENERATION TARIFF
This tariff is designed to reward home owners and businesses for playing a role in the removal of carbon emissions. It is a price in pence per kiloWatt hour (kWh) and is paid on the basis of the number of hours of electricity you produce. The table below outlines the rates paid for a solar photovoltaic (PV) system and applies to our tracking arrays.
Prior to the revision to the FiT, announced 6 weeks before it was withdrawn the guaranteed index linked return for installations up 4kW as 41.3p. This has now been revised down to 21p. The higher rate may be reinstated until 3rd March 2012. The current situation is somewhat confused. Please call for more information.
EXPORT TARIFF
The export tariff is 0.03p per kW generated. For ease of calculation, the electricity company will deem your PV installation to have exported 50% of what you generate. this is because most people are out at work during the day and will therefore be importing energy during the hours of darkness. Therefore the more you can use during the day (dishwasher, immersion etc) the more you will save.
By installing your array on a dual axis tracker you will be earning even more, because you will be paid 50% of a larger number every year that your equipment is silently generating power.
We predominantly have enquiries from the UK, however we are able to supply equipment to most major European countries. Various levels of service can be provided from a compete 'supply and install' service, to the supply of the dual axis tracker for your MCS approved supplier to install and register.
The photovoltaic effect refers to photons of light knocking electrons into a higher state of energy to create electricity. The term photovoltaic denotes the unbiased operating mode of a photodiode in which current through the device is entirely due to the transduced light energy.
Virtually all photovoltaic devices are some sort of photodiode. Solar cells are usually packaged behind a glass sheet to defend the cells from the elements. These multiple cell arrangements are known as panels and multiple panel arrangements are known as arrays.
This simple technology allows anything from 10watts to 55Mega Watts in power to be produced. Some of the biggest solar power stations are in Germeny and Spain and can generate nearly 100Gigga watt hours in a year.
It takes roughly 365 days for the earth to go around the Sun once. this means taht the Earth is travelling through space around the Sun at a rate of about 67,000 miles per hour! The time it takes for the Earth to travel around the Sun once is what we call a year.
So in addition to this, the Earths axis is tipped over about 23.5 degrees from vertical. The Earth rotates once every 24hours and to achieve this travel at 1000miles per hour! These two effects combine to make solar trackers the clear choice in harvesting the energy of the Sun.
Solar powered equipment works best when pointed at or near the Sun, so a solar tracker can increase the effeciveness of such equipment over any fixed position installation.
Full dual-axis tracking arrays take into account all the above movement of the Sun and the Earth to precisely collect solar energy and convert it into a useable source of electrical power.
Tracker sizing is unique to the installed power rating of the PV panels chosen by the client. The below table shows rough dimensions for some typical tracker sizes.

The Wattsun tracker (Array Technologies Inc) range in size from 1kW to 3.5kW on a single tracker. Deger Trackers (Deger Energie GmbH) manufacture equipment suitable from 2kW to a mammoth 12kW. We also install multiple trackers depending upon the clients specifications. There is no real limit to the number of trackers that can be installed on a site although planning, shading issues and electrical connection constraints usually have some influence.
Due to the fact we are specialists in tracking array technology we can install solar farms of multiple trackers but these are best suited to industrial applications due to their size.
The benefit of a tracker is that it requires no more ground works or footings than a standard ground mounted installation. The process of installation can be broken down into the following onsite jobs.
Drilling a hole 1.3m x 3m deep (this is variable depending upon site ground conditions)
Lay ducting from tracker to mains connection point.
Lifting pipe into hole and bracing in a vertical position.
