EcoCommercial uses the best quality photovoltaic (PV) panels: they come with a 10 year product failure warranty PLUS a performance warranty ensuring your system will still achieve 90% efficiency after 10 years and 80% after 20 years. We offer in-roof and on-roof systems.

We also offer an additional standard five year parts and labour warranty on your whole solar system, giving you peace of mind.

EcoCommercial recommends we pop in and carry out an annual inspection to ensure they system is working correctly and efficiently and is on target to provide you with the forecasted return on investment. The cost for the inspection is £280 inclusive.

How does it work?

The Science Bit... How do the panels work?

A PV solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels are made up of many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) Many cells linked together make up a solar panel.


Each photovoltaic cell comprises a sandwich made up of two slices of semi-conducting material, usually silicon. Photovoltaic cells need to establish an electric field to come to life. Like a magnetic field, which occurs due to opposite poles, an electric field is generated when opposite charges are separated. To get this field, manufacturers mix the silicon with other materials, giving each slice of the sandwich a positive or negative electrical charge.


Our PV panel manufacturers add phosphorous into the top layer of silicon, which adds extra electrons, with a negative charge, to that layer. Meanwhile, boron is added to the bottom layer, which results in fewer electrons, or a positive charge. This creates an electric field at the junction between the silicon layers. Then, when a photon of sunlight knocks an electron free, the electric field will push the electron out of the silicon junction where it is collected by metal conductive plates on the sides of the cell and tranferred to the system's wires. The electrons can then flow just  like any other source of electricity and sunlight has been converted into usable power.


Overview of Solar PV

PV stands for Photo Voltaic, PV solar systems convert daylight into D.C. current by means of solar panels which are made up from many PV cells. This D.C. current is then converted by an inverter into everyday A.C. current which can be used in the home or fed back into the power grid

Will PV Solar panels work during the winter?


Yes, absolutely. Solar panel manufacturing technology is very advanced and produces power even on totally overcast days.


Why should I consider a PV solar system?


PV solar systems are easy to install with minimal disruption and have no moving parts. PV is now a mature technology, is guaranteed at a minimum 80% efficiency for 25 years, creates no pollution and is silent when operating.


What are the disadvantages to installing a PV solar system?


The only disadvantage is the initial cost outlay; however this is offset by the feed in tariff you will receive, the export payments you receive and the savings on electricity that you will not need to purchase.


How big a PV solar energy system do I need?


he size of solar system you decide to purchase depends on the available space to install the panels and how much you choose to invest at the outset.
