Before we start working on a proposal for your site we will request a large suite of information including 12 months' Half Hourly electricity meter data, Electricity Pricing information, Electrical schemtatics, as built construction drawings, ownership boundaries and other site specific information.

There are 3 mains things to consider when planning the size of a commercial Behind-The-Meter Solar PV System - How much electricity do I need? How much space do I have? How big is my electricity supply? All of these will influence how large a system you should aim to install and Emtec Energy will work with you to engineer the most cost effective solution.

There is almost always a solution for fixing PV modules to a roof, though some roofs are more efficient and cost effective than others. Metal sheet roos with a trapezoidal or box profile are by far the most cost effective and quick to install on. Flat and Standing Seam roofs are also very common for mounting on, other roof types tend to be less common with more expensive mounting systems.

Generally, the smallest project we would work on would be 100kWp of Solar PV, which equates to around 240 individual PV modules which would require in the region of 550 square metres of clear roof space. There is no upper limit of project size that we would work on and we would encourage you to contact a member of our team directly to discuss your project.

Effectively all ground mounted Solar PV Systems will require Full Planning Permission. In England & Wales, roof mounted Solar PV Projects up to 1MWp fall under Permitted Development, though full Planning Permission may still be required in certain areas. In Scotland, at the time of writing, commercial roof mounted Solar PV projects of up to 50kWp fall under Permitted Development Rights, however, it is expected that by Summer 2024 these Permitted Development rights will have been brought up to at least 1MWp. To discuss the specific requirements of your project please contact a member of our team.

The Solar PV modules that Emtec Energy will install for you will come with a 25 Year Performance Warranty, which is generally seen across the industry as the minimum useful life of the system, though it may well operate efficiently for much longer. It is likely that within this 25 Year period that the inverter system will require to be replaced, standard warranties for inverters range from 5-12 Years depending on the manufacturer.
