The wrong contractor puts everything at risk. Weak design leads to lower energy yield. Poor procurement brings late or substandard equipment. Thin finances can leave a half-built site if the contractor fails. Each risk means delay, lost revenue and penalties under your power purchase agreement or financing.
Choosing an EPC Partner, From an EPC Contractor
We know what lenders and buyers look for, because we are assessed the same way. USP&E has delivered 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, including hybrid plants that add solar to engines and storage. Our systems are ISO 9001 and ISO 45001 certified. USP&E is a full-service EPC and O&M contractor, not a broker.
Here are the questions that separate a reliable solar EPC contractor from a risky one.
Is the Scope Truly Turnkey?
Start with what the contractor will actually deliver. A full EPC contract should cover design, procurement, construction, commissioning and performance testing under a single point of responsibility. Check what is excluded: grid connection works, the substation, permits and land preparation are common gaps.
Every gap is risk that comes back to you. If several contractors share the work, someone has to manage the interfaces, and that someone is usually you. Put the scope on one page and check each item against the bid before you compare prices.
Track Record, Team and Financial Strength
Ask for projects of similar size and type, with references you can call. Look at who will actually run your project, not just the company’s history. The project manager and site team matter more than the brochure, so ask to meet them before you sign.
Check financial strength. A contractor must be able to carry the project through its peak spending months and stand behind its guarantees. Ask about bonds, parent guarantees and insurance. Our power plant EPC projects page shows the kind of evidence you should ask any contractor for.
Design, Procurement and Guarantees
Strong design teams squeeze more energy from the same site through layout, mounting choice and electrical design. Ask how the contractor models energy yield and what assumptions it uses. Our guide to levelised cost of electricity explains why small yield differences matter so much to project value.
Procurement strength means reliable module, inverter and structure supply at fair prices, with clear warranties. Look closely at guarantees: completion date, plant capacity, performance ratio and availability, and the damages paid if they are missed. Damages that are capped too low give the contractor little reason to recover a slipping schedule, so check the caps against your own revenue at risk. Ask too how long module and inverter warranties run, and whether the contractor will manage claims for you during the early years of operation.
Safety, Quality and Life After Handover
Ask for the contractor’s safety and quality records and certifications. Then think beyond construction. Who will operate and maintain the plant? A contractor that also offers O&M has an incentive to build for the long term, because it will live with any shortcuts it takes during construction.
Many projects now add firm power through hybrid systems. We also deliver natural gas engines/stations, used/new gas turbines, gas turbine generators and a remanufactured GE Frame 6B, plus hyperscale EPC/O&M with AI gas turbines, hyperscale generators, gas turbines for compute and New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA. See our equipment inventory.
Local Teams Near Your Solar EPC Site
Data-centre schedules are won or lost in permitting, gas supply and interconnection, so USP&E puts its US offices first. Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) give you two US bases for engineering reviews, procurement follow-up and site visits, and both teams work your solar EPC and gas firming project alongside you rather than from a sales desk.
Behind them, London (162-168 Regent Street) handles structuring, bonding and finance; Johannesburg (22 Kildoon Rd, Bryanston) owns engineering and project controls for PV blocks, natural gas engine firming and GT bridges; Cape Town (31 Brickfield Road, Woodstock) supports design and commissioning; and Wuxi, China (No. 1, Ningzhou Road, Wuxi) manages China manufacturing and supply-chain follow-up.
Solar EPC work in Africa runs from Johannesburg and Cape Town. Projects in the Americas go through Colorado Springs and Knoxville, London manages contracts and finance, and Wuxi supports modules. Regions served: USA | AFRICA | UK | UAE | CHINA. That network stands behind 150+ power projects in 45+ countries and 25,000 MW contracted since 2002, run under ISO 9001 and ISO 45001 certified systems.
What USP&E Has Delivered for Solar EPC Buyers
An EPC contractor is judged by what it has built. These are projects USP&E has delivered.
- USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers.
- A gold mine in West Africa: USP&E rebuilt more than 80 MW of Caterpillar CM32 engines and added 24 MW of new zero-hour capacity, delivering a 104 MW station with 300% greater reliability and availability than previously recorded at site. Read the case study.
- A giga-project developer in the Middle East: USP&E supplied three zero-hour Siemens SGT-400 gas turbines as the single technical and commercial interface.
How to Shortlist Solar EPC Contractors
Your 3-step plan: 1. Share your project size, site and timeline. 2. Get a clear scope, schedule and guarantee package. 3. Sign one contract that covers building, commissioning and operation.
- Write a clear scope and performance target.
- Ask for projects of similar size and type.
- Check the team that will run your job.
- Compare risk terms, not only price.
- Check warranties and who supports them.
- Plan the O&M handover before you sign.

FAQ: Solar EPC Contractors: How to Choose One
What does a solar EPC contractor do?
USP&E describes a solar EPC contractor as the firm that designs the plant, procures the modules, inverters and structures, and builds and commissions it, usually under a single point of responsibility. The contractor typically guarantees completion date, capacity and performance.
How do I choose a solar EPC contractor?
USP&E suggests comparing scope, track record, the actual project team, financial strength, design and procurement capability, guarantees, safety and quality records, and O&M after handover. Price matters, but the cheapest bid can become the most expensive if any of these are weak.
What guarantees should a solar EPC contract include?
USP&E expects solar EPC contracts to guarantee completion date, plant capacity and performance ratio, often with availability guarantees during early operation. Each should carry clear damages if missed. Bonds, parent guarantees and insurance show the contractor can stand behind these promises.
What is often excluded from solar EPC scope?
USP&E sees grid connection works, the substation, permits, land preparation and sometimes security left out of solar EPC scope. Every exclusion is risk returned to the developer. Checking exclusions early lets you price and manage these gaps before the contract is signed.
Which USP&E offices support solar EPC projects?
USP&E prices and builds solar plants for African developers from Johannesburg and Cape Town; for the Americas, the Colorado Springs and Knoxville teams lead. London prepares contracts, bonds and finance. Wuxi helps secure modules and inverters from Chinese factories, so engineering, procurement and construction stay under one roof.
What EPC work has USP&E delivered?
USP&E has delivered 150+ power projects in 45+ countries. One West African iron ore mine received a 16 MW station that was finished within five months, two months earlier than planned. Lenders and developers look for that kind of evidence when they compare EPC bidders.
Is USP&E a broker or an EPC contractor?
USP&E is not a broker. Ours is a design and build contractor, so its engineers design, buy for, construct and later run the plants they bid on. It takes responsibility for delivery, safety and quality, and for how your plant performs after handover.
How quickly can USP&E respond to a solar EPC enquiry?
USP&E can review your project size, site and timeline as soon as you share them. Engineers set out the scope, the main risks and the critical path first, so you can compare our approach with other bidders early in your selection.
Choose a Contractor That Stands Behind the Plant
Check scope, team, finances and guarantees, and your solar EPC contractor will deliver a plant that performs. Choose on price alone, and the risk returns to you. USP&E will help you build with confidence.
