Disclaimer

Editorial, not advice

Solar Ledger publishes journalism. Nothing on this site constitutes engineering, electrical, structural, legal, tax or investment advice, and no article creates a professional relationship between you and the publisher or its writers.

Safety

Photovoltaic systems carry DC voltages that remain live in daylight, and most installation work happens at height. Design, installation and commissioning must be carried out by qualified, licensed professionals in accordance with local codes and the manufacturer's instructions. Never treat one of our articles as an installation manual.

Figures and modelling

Yield, payback, degradation and battery-life numbers are estimates based on stated assumptions. Real results vary with irradiance, shading, roof geometry, tariffs, equipment quality and workmanship. Where we show arithmetic, we show it so you can substitute your own inputs — not because the result will hold for your site.

Accuracy and currency

Grid rules, incentives and prices change frequently. An article is accurate to the best of our knowledge on its publication date and is not continuously updated. Verify regulatory and pricing claims against the current primary source before relying on them. Corrections are welcome via the contact form.

Affiliate and advertising disclosure

Some articles contain affiliate links, which may earn us a commission at no extra cost to you. The site also carries third-party advertising. We do not accept payment for coverage, and no advertiser or affiliate partner sees articles before publication or influences our conclusions.

External links

Links to datasheets, standards and other publications are provided for verification. We are not responsible for the content, accuracy or availability of third-party sites.

Liability

To the maximum extent permitted by law, we accept no liability for loss or damage arising from reliance on information published here. Your use of the site is also governed by our Terms & Conditions.
