Solar Energy jobs in Wallingford

About Spirit Energy
We design and install high-quality solar PV and battery storage systems for homes and businesses across the South of England. Based in Reading, we’re one of the UK’s longest-established and most respected specialists in residential and commercial renewables. Our work is technically led, with a strong focus on engineering excellence and long-term system performance.

We’ve built a reputation for honest advice, meticulous design, and high-quality installations. Our mission is to help people take control of their energy, reduce their bills, and accelerate the UK’s shift to a sustainable future.

You don't need to know anything about the industry. We will train you. We offer a fast growing and fun environment full of young people.

About the Role
We’re looking for a bright, motivated graduate to join our residential sales team. Your main job is to sell solar and battery storage systems to homeowners – from first contact through to closing the deal.

When a potential customer gets in touch, the project becomes yours to manage. You'll be responsible for taking it from first enquiry through to final quote and signed contract. That includes assessing the property, advising on the right system, putting together the proposal, and handling any follow-up. You won’t be micromanaged – we’ll give you the tools, training, and support you need, but you'll be expected to run your own pipeline and take ownership of your work.

But this isn’t just a sales job. Our customers rely on us for second-to-none technical advice and clear, honest insight into the best system specification for their property. You’ll be trained in every aspect of solar and battery system design, from first principles to advanced applications. This includes how to size systems correctly, quote accurately, and select the right technologies for each project based on performance, cost, and customer needs. You’ll learn how to model energy generation and savings, analyse household energy loads, and forecast long-term performance. You’ll also gain practical experience with schematics, CAD drawings, and the technical documentation required for grid approval, including DNO applications. And much more...

We’re not looking for a pushy salesperson – we’re looking for someone smart, curious, and commercially aware who can help customers make informed decisions.

You’ll also get the chance to work closely with our technical and design teams, and over time, you may choose to specialise more in either the sales side or the technical side of the business.

The company is growing quickly and we're looking to expand into new areas and new technologies. You'll be a part of driving this growth and contributing to the development and expansion of the company.

Key Responsibilities

• Engage with homeowners via phone, email, and video to understand their needs
• Recommend technically sound and cost-effective solar and battery storage solutions
• Prepare performance estimates, technical system layouts, and customer proposals (training provided)
• Manage your own sales pipeline and follow up on leads promptly
• Visit customer properties to assess installation feasibility and finalise proposals (once trained)
• Collaborate with our in-house engineers and designers to ensure system designs meet customer expectations
• Hit monthly sales targets and earn commission on closed deals

Who We’re Looking For

• A bright, articulate graduate (2:1 or above preferred) in a STEM subject – engineering, physics, maths, or similar
• Someone who enjoys technical detail but is also confident speaking to people and handling objections
• A clean communicator, both verbally and in writing, with the ability to clearly explain technical ideas.
• Organised and self-motivated, with strong attention to detail
• Willing to learn fast and take ownership of your performance
• A full UK driving licence is required (or commitment to obtain one)
• You will need to be in the office 5 days per week, although you will be allowed to WFH when required.

Pay and Progression

• Base salary: £28,000
• On-target earnings (OTE): £40,000–£60,000+ in your first year if you perform well
• Longer-term pay will be based on the value you bring to the company – whether in sales, technical, operations, or leadership
• We believe in rewarding performance and promoting from within – many of our team members have developed into senior roles within a few years

Our Values
We care about doing things properly. We design systems that work, support customers honestly, and push to improve standards in the renewables industry. We believe in:

• Engineering excellence
• Attention to detail
• Technical education and development
• First-class customer support
• Safety, sustainability, and integrity
