Resources

Technical resources for solar thermal system design and maintenance.

• Sizing Calculator — DHW load + collector area + tank volume, with an annual-yield projection
• Collector Tilt Optimizer — pick collector tilt for minimum unmet demand, not maximum yield
• Collector Efficiency Reference — how a datasheet η₀ becomes the much smaller annual delivered fraction
• NTC Thermistor Calculator — calculate thermistor resistance at any temperature
• Wheatstone Bridge Calculator — model bridge circuits for precision sensing
• Corrosion Inhibition — protect your thermal store with sodium silicate and sodium sulfite
