A savings calculator
A visitor enters a rough monthly bill, and the site shows an estimated system size and potential saving. It is clearly marked as an estimate, and it invites the visitor to request a proper quote.

Websites for solar installers
Choosing solar is a big decision, and most homeowners and business owners do their research online before they ever call an installer. A good solar website answers the first questions clearly and moves a serious buyer towards asking for a quote.
Spark Website Studio is a new studio led by me, Joshua Webb. I work online only, on WhatsApp and email, for installers across South Africa, and I build solar websites that explain clearly, calculate honestly and make it easy to ask for a quote.
What solar buyers want to know
Visitors to a solar site tend to ask the same questions, in roughly the same order. The site should answer them before the visitor gets frustrated and leaves.
- How much could I save, and how long until the system pays for itself?
- What size system do I need for my home or business?
- Will it keep the lights on during load shedding, or only cut my bill?
- Are you qualified, and can I see work you have done?
- What happens next if I ask for a quote?
Features that help you win quotes
System sizes explained simply
A short guide that explains inverters, panels and batteries in everyday language, and what small, medium and large systems usually run. No jargon wall.
Quote requests with a bill upload
The customer attaches a photo or PDF of a recent electricity bill. You see their real usage before you call, so your first conversation is useful.
An installation gallery
Photos of finished roofs and neat wiring, with a short caption about the system and the site. Real work builds more trust than stock photos.
Accreditations in view
Your qualifications, such as a PV GreenCard, displayed clearly with what they cover. Customers and insurers look for these.
Finance options
If you offer finance through a partner, a short, honest explanation of how it works and who to contact.
See a solar website demo
Volta Ridge Solar is a demo website for a made-up installer. It has a live energy display and a savings calculator, to show how these features can look and work. It is a demo, not a client project, and its numbers are examples only.
Honest numbers, clearly labelled
Solar claims need care. Savings depend on the roof, the weather, the tariff and the household. A calculator that overpromises damages your reputation and invites complaints.
I build calculators that show a sensible range, state their assumptions in plain words and invite a proper site assessment. That approach attracts buyers who value honesty, and those are the customers you want.
How it works
Send me the basics
Your services, system sizes, service areas, accreditations and photos of installations. Tell me which figures the calculator should use.
See a free preview
I build a preview with your branding and send you a link. You test the calculator and tell me what to change.
Get a written quote
If you like it, you receive a clear written quote, including running costs such as your domain name. Nothing starts until you agree.
Launch
I put the site live on your own domain and check the forms, the bill upload and the calculator on different phones.
If you also do general electrical work, see the page for electricians, plumbers and builders. For the general approach, read about website design, and for typical prices see the cost guide.
Frequently asked questions
Can the savings calculator show real numbers?
It can show estimates based on the figures you give me, such as typical sun hours, your system sizes and local tariffs. I label it clearly as an estimate, because the real result depends on the home, the roof and how people use power.
Why ask customers to upload an electricity bill?
A bill shows how much power a customer uses and what they pay. With it, you can recommend a sensible system size and quote more accurately. Customers who upload a bill are usually serious, which saves you time on early enquiries.
Can I show my accreditations?
Yes, if you hold them. I show what you give me, such as a PV GreenCard, and I do not list any accreditation you do not have. Customers and insurers often check, so accuracy matters.
Can the site mention finance options?
If you offer finance through a partner, the site can explain how it works and link to the partner. I do not give financial advice or show figures you have not confirmed, and the details come from you.
