Solar Solutions For Your Business
Solar PV has already helped thousands of UK businesses reduce their carbon emissions, reduce their energy costs and increase their energy security. There is an ever increasing pressure on businesses across the supply chain to decarbonise and an on-site solar PV system is a cost effective and well tested method of achieving both carbon reductions and reducing energy costs. Poweri services have installed hundreds of solar PV systems onto non-domestic buildings across the country and we can provide you with a first class system, delivered to the highest standards of design, construction and ongoing care.
The delivery of a larger solar PV project is typically carried out in 3 phases, Development, Construction and Operation & Maintenance.
(4-26 weeks depending on project type and complexity)
The development phase of the project is required to obtain all relevant approvals for the project and to finalise the system design and construction methodology. This ensures that the PV system is ultimately installed safely and in accordance with all required regulations, as well as to your and our high standards.
This phase is also where project funding will be secured if required.
Our industry leading experts in developing solar PV systems and our integrated project management approach lead to the smoothest possible project delivery every time. The key tasks for the development stage of the project are:
In order to ensure that the proposed system can be installed as planned, we carry out a detailed site survey specifically tailored to the proposed solar PV project.
All generators that are connected to the Grid and will generate more than 16A/phase must have their connection pre-approved by the local DNO under ER G59 regulations
Solar PV system design:-
The detailed design of a solar PV system involves the mechanical and electrical integration of all of the PV components into the existing building fabric in such a way as not to disrupt the operation of the building, as well as insuring the safe and efficient operation of the PV system over its lifetime.
Energy Performance Certificate:-
The current Feed in Tariff regulations require that with some limited exceptions, all buildings much have an EPC rating of D or better in order to qualify for the higher rate of FiT payments for their size banding.
One of the key considerations of the suitability of a building for the addition of solar PV panels is the strength of the existing roof structure and its ability to accept the additional dead and wind loadings imposed by the solar PV system, as well as its ability to serve as a safe working platform during installation and any maintenance works.
It is a key responsibility of building owners to keep and maintain records of the presence and condition of any Asbestos Containing Materials (ACMs) in their premises. It is also a key responsibility of us as an employer to take all reasonable precautions to protect our staff from exposure to ACMs and to this end we will always carry out a review of the asbestos surveys and records available during the development phase of a project. If the existing records are found not to cover the areas where we will be working, are inadequate to assess the risk, or absent altogether then we require that an Asbestos R&D survey be carried out covering the affected areas and any remedial and removal works recommended carried out prior to commencement on site
Planning permission / Permitted Development:-
The majority of solar PV installation in the UK should fall under permitted development regulations provided they meet a few basic design requirements. With Key potential exceptions being listed buildings (Or buildings on a listed site), buildings in or near a conservation area and systems bigger than 1MWp. It is recommended that even if we are confident that the system will fall under permitted development that confirmation be sought from the local planning office, and if permitted development does not apply then full planning permission must be sought and given prior to the commencement of works.
Building Regulations Compliance:-
Various elements of works needed during the installation of a Solar PV system fall under category of notifiable under building regulations, most notably the additions to the electrical system and potentially the additional loads placed on the structure of the roof.
Preparation of site specific RAMS and CPP:-
A key consideration of the viability and cost of a solar PV installation is the safety of the installation works and the systems continued operation & maintenance. The cornerstone of this assessment is the preparation of detailed and site specific Risk and Method statement covering the works. If the project is notifiable, or requires the services of a Principal Designer under CDM regulations then we will also need to prepare a Construction Phase Plan (CPP) to demonstrate that we have carefully and properly considered all foreseeable risks in the project and takes steps to address and reduce those risks. We also believe that it is not possible to fully assess the true costs of a project until this has been carried out, as some necessary safety arrangements may be highlighted that require some cost to be incurred in removing that risk
Securing of funding stream (If required):-
If the project is to be funded by a third party under a Power Purchase Agreement, then the final contract for this funding will need to be signed before construction begins, but once all costs are known and all approvals have been obtained.
Our process for completing the development phase of these projects is to:-
(Typically 1 to 2 days per 10kWp)
The construction phase of the project comprises the time period from the initial arrival on site and the habitation of welfare facilities to the date when all plant and materials have been removed following the completion of the project and welfare facilities have been vacated.
Poweri Services Ltd would usually act as principal contractor for this period unless another party is appointed to fulfil this role
The key tasks for the construction phase of the project are:-
(Ongoing for system lifetime – 20-35 years)
The Operation and Maintenance phase comprises the full operation al lifetime of the solar PV system (Typically 20-35 years). Whilst solar PV systems are relatively low maintenance, because they are revenue generating appliances and represent a significant saving on imported electricity costs, their smooth operation has significant financial value.
Poweri Services Ltd strongly recommend entering onto a formal O&M contract to ensure the trouble free operation of the solar PV system for its lifetime. In our experience it is all too easy for the system to be forgotten once it is working, particularly if staff roles or responsibility changes happen, and we have seen instances of system being non-operational for some time due to simple reasons leading to significant lost income when having a dedicated supplier looking over the system would have picked up and rectified the problem quickly.
Poweri Services Ltd offer a system yield guarantee for the duration of O&M contract. Please contact us for full details
Key indicative tasks in the O&M phase of the project are:
1. PV Modules & mounting system checks
2. Inverter checks
3. Electrical Tests
The full extent of checks and tests required will be finalised and agreed prior to the commencement of the O&M contract and may differ depending on the individual system requirements
Poweri have been incredibly professional in the way they have undertaken this project. They have delivered in a timely way throughout duration of the project, keeping to their original budget. Poweri worked very well with all the other contractors on site and they have supported us enormously with all the OFGEM paperwork. The project was a huge project for us, but we always knew we could rely on Poweri, particularly at critical points.
