How This Works
- We may mention or link to specific solar products.
- If those links contain affiliate tracking parameters and you make a purchase, the retailer pays us a small commission.
- The commission does not increase your price.
- Commissions typically range from 3% to 8%.
Our Editorial Standards
- ✓ Technical merit first — recommendations based on engineering analysis, not commission rates
- ✓ No fake reviews — we only recommend products we have technically evaluated
- ✓ No paid placements without disclosure
- ✓ Negative reviews allowed — we will recommend against a product if our analysis shows poor value
Cookies
When you click an affiliate link, the retailer sets a tracking cookie (typically 1-30 days). You can disable third-party cookies in your browser — this will not affect our calculator functionality.
