Building your solar park
Once your solar park project has been planned, and you have decided to develop it yourself, Ownergy's co-developer role becomes that of project manager.
Step 5 - Final design and tendering
The following primary items and services will need to be specified and procured:
- Solar PV modules
- Solar array ground fixings and tilt mounting structures
- DC-AC inverters with PV power-tracking capability and 3-phase output at the required voltage
- Bulk cabling and conduit
- Ground-works and foundations
- DC switchgear, protection and connection
- AC switchgear, protection and connection (including DNO interface)
It may be possible to combine more than one of these in certain sub-contracts to enhance interfacing and cost-effectiveness. Alternatively we may decide to combine most or all of these elements in a single EPC contract. All proposed contracts would be costed and agreed with you on an ‘open book’ basis prior to placement.
We have developed a template EPC contract which can be used to define the agreement between the project owner and the EPC contractor.
At this stage the specific costs of the grid connection will also be finalised.
Step 6 - Construction and commissioning
We would then manage the construction and installation phase of the project.
This would be done on a flat fee basis to be agreed in advance. As Ownergy is often able to improve the financial performance of the project then we would hope to agree a gain-sharing arrangement on such items as:
- Delivering capital cost below the target level
- Achieving normalised annual system output above the specified level
- Negotiating an export tariff above the 3p per kWh regulated level
