Solar Project Portfolio: How to Showcase Installations That Win Customers

Every solar installer says they do quality work. The ones who win customers show it.

Your completed projects are the most convincing marketing you have. A homeowner who sees a neat 4 kW installation on a house just like theirs, two streets away, with the owner saying their bill dropped, doesn’t need much more persuading. Yet many solar websites have a gallery of five unlabelled photos, or nothing at all.

This guide explains how to turn your installations into a portfolio and case studies that build trust and bring in site surveys.

Why projects matter so much in solar

• Solar is a long-term purchase. Customers want proof you’ll still be around and that your systems keep working.
• Quality varies a lot. Neat cabling, proper earthing and a solid mounting structure are things customers can see in good photos, and they notice.
• Local proof is powerful. “Installed in your area” removes a lot of doubt.
• It helps search. Project pages with real details give Google fresh, location-specific content, which supports your local SEO for solar.

What to record for every installation

Make it part of your commissioning checklist. For each project, capture:

• Customer type: independent house, housing society, school, factory, shop
• Location: area and city (not the full address unless the customer agrees)
• System size in kW
• System type: on-grid, hybrid with battery, off-grid
• Components: panel and inverter brands and models, battery if any
• Roof type and structure: RCC flat roof, elevated structure, tin shed
• Challenges solved: shading, limited roof space, a tight deadline, a heritage building, weight limits
• Timeline: survey to commissioning, and subsidy timeline if it applies
• Results, after a few months: units generated and change in electricity bill, from the customer’s actual data
• A customer quote, with permission

The results are the most valuable part, and the one most installers skip. Set a reminder to ask the customer for their bill or generation data three to six months after commissioning.

How to photograph a solar project

You don’t need a professional photographer, but you do need a routine.

• Wide shot of the full array in good daylight, showing the whole roof
• Drone shot for larger rooftops and commercial projects, if you can (follow local drone rules)
• Close-ups of quality details: cable management, junction boxes, earthing, mounting structure
• The inverter and meter installation, neat and labelled
• Before and after of the same roof from the same angle
• The team at work, with safety gear on
• The customer with the system, if they’re happy to appear

Shoot in landscape, keep the horizon straight, and avoid harsh midday glare where you can. Convert photos to WebP and compress them before uploading so the page stays fast.

Structuring your projects page

A good projects page lets visitors find work like theirs quickly.

• Filters by customer type (home, society, commercial, agriculture), system size and city
• A card for each project with a photo, system size, location and one line about the result
• A detail page for your best projects, with full photos, specs and the story
• A running total, such as total installations or total kW installed, but only if you have the real figure and keep it updated
• A survey booking button on every project page: “Want a system like this? Book a free site survey”

Writing a solar case study

Pick your best projects, especially ones that represent the customers you want more of, and write them up properly. A simple structure:

1. The customer: who they are and where (with permission).
2. The challenge: high bills, frequent power cuts, limited roof space, a society that needed all residents to agree.
3. The solution: system size and type, components, design choices, how you handled the challenge.
4. The installation: timeline, anything unusual, how you handled approvals and net metering.
5. The results: real generation and bill figures after a few months, in the customer’s own words where possible.
6. The quote: a short line from the customer.

Commercial case studies need more numbers: load profile, units generated, savings over a period and payback, all from real data. They matter most for factories, offices and schools, which we cover in how to build a commercial solar EPC website.

Never estimate results and present them as actual. If you don’t have the data yet, describe the project and add results later.

Getting customer permission and quotes

• Ask for permission to use photos, location and their name in writing (a WhatsApp message is fine)
• Offer to keep their name private and use only the area (“Homeowner, Kothrud”)
• Ask two or three easy questions: Why did you choose solar? What was the installation like? What changed on your bill?
• Use their words with light editing, and send it back for approval

Using projects across your site and marketing

• Show the three most recent projects on your homepage
• Show local projects on each city page
• Show matching projects on each service page (society projects on the society page, and so on)
• Link relevant projects from your subsidy page as proof of the process
• Share each new project on Google Business Profile, Instagram and Facebook
• Send project links to new enquiries in their area when you follow up
• Turn interesting projects into blog posts. There are more ideas in solar blog content ideas

Mistakes to avoid

• Stock photos presented as your own work
• Photos with no details: no size, no location, no result
• Inflated or estimated savings shown as real
• Using customers’ names or photos without permission
• A portfolio that hasn’t been updated in a year
• Huge uncompressed images that make the page slow

Key takeaways

• Real projects are your most convincing proof of quality
• Record size, location, components, challenges and real results for every installation
• Follow a simple photo routine, including quality close-ups and before/after shots
• Make the projects page filterable by customer type, size and city
• Write detailed case studies for your best projects, using only real data
• Reuse projects on city, service and subsidy pages and across social media
