How to write a solar blog post that works

• Answer the question in the first few lines. Then explain in more detail.
• Use plain language. Explain terms such as kW, units, net metering and inverter the first time you use them.
• Use real numbers carefully. Give ranges, say where figures come from, and date anything that changes, such as subsidies and tariffs.
• Add your own experience. “On most flat RCC roofs we survey in Pune…” is more useful than generic advice, and Google values first-hand expertise.
• Use your own photos from real installations.
• Add a clear next step in every post: try the savings calculator, send your bill on WhatsApp or book a free survey.
• Link to your service and city pages where they’re relevant, so readers and search engines can find them.
• Update older posts when rules, prices or products change, and show the updated date.

How to get more from each post

• Share every post on Google Business Profile, Facebook, Instagram and LinkedIn
• Turn the key points into a short reel or carousel
• Save common answers as WhatsApp quick replies with the post link
• Send a monthly newsletter or WhatsApp broadcast to past enquiries with your latest posts
• Link related posts to each other so readers keep going
• Check Search Console every few months to see which posts bring visitors, and write more like them

Content also supports your local rankings. Our local SEO guide for solar installers explains how blog posts, city pages and your Google profile work together.

Key takeaways

• A blog meets solar customers early in their research and builds trust

• Answer the question quickly, in plain language, with your own experience and photos
• Date and update anything that changes, especially subsidies and tariffs
• End every post with a clear next step and links to your service pages
• Reuse posts on social media, WhatsApp and newsletters
