How to evaluate solar & renewables web developers in Johannesburg
5 things to check before hiring
These are the questions and checks that separate solar & renewables specialists from general web agencies who will list your sector on their homepage after you sign.
ROI/savings calculator: interactive tool allowing the visitor to input property size, electricity bill, and roof orientation to see estimated savings, the single highest-converting element on solar websites
Accreditation badges with verification links: MCS certificate number (UK), CEC accreditor ID (AU), NABCEP ID (US), displayed prominently with direct links to the relevant registries
Case study pages with before/after bills, system size, installation timeline, and verified Google review: one genuine case study outperforms six testimonial quotes
Finance/payment option page: solar purchase, solar loan, PPA, and leasing explained clearly, most Johannesburg buyers decide on payment model before brand
Postcode/state eligibility checker for government incentives: interactive eligibility for UK Smart Export Guarantee, AU STC rebate, US federal ITC, or state incentive programmes
Platforms & Tech Stack
Which platform for solar & renewables in Johannesburg?
WordPress with custom ROI calculator
Most Johannesburg solar installers use WordPress. The ROI calculator is the key custom element, built in React or vanilla JS, embedded as a WordPress block. This is the highest-converting page element and should be built by a developer, not a plugin.
Next.js for enterprise solar companies
Large solar installation companies with multiple product lines (residential, commercial, battery storage) benefit from a Next.js build with individual product-category landing pages and a dynamic savings modelling tool.

Questions & Answers
Solar & Renewables web development in Johannesburg - common questions
Pre-brief questions that solar & renewables businesses in Johannesburg ask before commissioning a web project.
What should a solar company website include to generate leads in Johannesburg?+
The three highest-impact lead generation elements for a solar website in Johannesburg in 2026 are: 1) An interactive savings calculator using postcode-level solar irradiance data, visitors who use a calculator convert at 3–5x the rate of those who don't; 2) Accreditation verification links (MCS, CEC, NABCEP) rather than just logos, buyers are increasingly checking these; 3) Finance options clearly explained, cash vs loan vs PPA vs lease, because most prospects eliminate themselves before calling if they cannot see a payment route they can afford. Without all three, solar websites in Johannesburg generate enquiries primarily from price shoppers.
How long does it take to rank a solar website in Johannesburg?+
Solar installer SEO in Johannesburg takes longer than most trades because it competes with well-funded national comparison platforms. A properly structured solar website with location-specific case studies and calculator tools typically enters the local 3-pack within 3–5 months. National organic rankings for 'solar panels Johannesburg' take 6–14 months. Government incentive terms ('solar panel grants Johannesburg', 'smart export guarantee Johannesburg') rank faster, 8–16 weeks, because comparison platforms rarely target specific incentive scheme pages.
What should a Johannesburg business look for in a contract before hiring a web developer?+
A properly scoped web development contract for a Johannesburg business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover, this is a red flag in the Johannesburg web development market.
How long does a Johannesburg web project typically take from brief to launch?+
A standard business website for a Johannesburg company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Johannesburg web projects is late content delivery from the client, agree a content deadline before the project starts and the timeline holds reliably.
Should a Johannesburg business hire a local web developer or work with a remote agency?+
For most Johannesburg businesses, a remote web development agency delivers equivalent or better results than a local studio, at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for web development quality since 2018. Tecklogist serves clients across South Africa and 40+ countries entirely remotely.
How can a Johannesburg business verify a web developer's experience before signing?+
The three most reliable verification methods for Johannesburg businesses evaluating web developers are: 1) Live portfolio links, the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references, ask for contact details for two recent clients in a similar sector; 3) Technical audit, ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tecklogist provides live portfolio URLs, verified client references, and a free technical scoping call for every Johannesburg project enquiry.
