ENGINEERING-LEVEL SOLAR EXPLAINERS • return on investment • AIR QUALITY

Solar that pays back — and helps us all continue to breathe.

www.bloist.com is a static site built to make the technical case for residential solar: economics, grid interaction, and real-world air quality impacts.

Clean generation, right where you live

Distributed solar reduces demand on polluting generation, cuts line losses, and can pair with storage for outages.

The problem is visible

When power is produced far away, the costs are hidden: air pollution, fuel price volatility, and grid stress. Solar moves part of generation to the edge, closer to load, with predictable output and no combustion.


What this site covers
  • Air quality snapshots for major cities (fine particulate matter smaller than 2.5 micrometers / nitrogen dioxide)
  • photovoltaic technology fundamentals (panels, inverters, shading)
  • Economics: incentives, financing, uncertainty, payback
  • Resilience: critical-load planning + battery sizing

Depth & breadth — without frameworks

This site is built as pure HTML/CSS/JS for fast a simple static host hosting, with a multi-layer dropdown menu, responsive layout, and chart-driven reports.

Technical, not fluffy

Explains photovoltaic system topology, clipping, temperature effects, performance ratio, and realistic sizing constraints.

Decision-grade economics

Side-by-side comparisons for cash vs loan vs power purchase agreement, plus a quick calculator you can tweak in seconds.

Air quality context

Visuals that connect smog days and emissions to demand on polluting generation—and what distributed solar can change.
