Disclaimer

General information only

Everything published on [YOUR DOMAIN] is general educational information about solar photovoltaic technology. It is not engineering advice, electrical advice, structural advice, tax advice, or financial advice, and it is not tailored to your property, your climate, your electrical installation or your finances.

No article here substitutes for a site-specific assessment by a qualified professional who has inspected your property and who is licensed in your jurisdiction.

Electrical and roof safety

Solar installations involve two serious hazards: mains-voltage alternating current, and working at height. A photovoltaic array also produces dangerous direct-current voltage whenever light falls on it, and unlike an appliance it cannot simply be switched off — the panels are live in daylight.

Do not attempt installation, repair or modification of a solar system unless you hold the relevant electrical qualifications and licences for your area. In many jurisdictions grid-connected work is illegal to perform without certification, and unqualified work commonly voids equipment warranties, invalidates building and contents insurance, and can be fatal.

Where our guides describe how something works, that is explanation, not instruction to carry it out yourself.

Figures, calculations and estimates

Solar output depends on latitude, local irradiance, roof tilt and orientation, shading, temperature, equipment quality and installation workmanship. Any figure we publish is an illustration based on stated assumptions, and your result will differ.

Cost, savings and payback numbers depend additionally on hardware pricing, labour rates, electricity tariffs, tax treatment and subsidy schemes, all of which change and none of which we control. Treat every financial figure on this site as a worked example to be re-run with your own inputs, not as a projection you can rely on.

Product references

Where we name equipment, we do so for identification and comparison. Specifications are drawn from manufacturer documentation available at the time of writing and may be superseded. Always confirm against the manufacturer's current datasheet before purchasing. Trademarks belong to their owners, and mention does not imply endorsement, affiliation or that a product is suitable for you.

Regulations and incentives

Grid connection rules, net metering terms, permits, building codes and incentive schemes vary by country, region and utility, and change frequently. Anything we write about regulation is a summary for orientation only. Verify current requirements with your regulator, your distribution company and your local authority before making commitments.

External links and advertising

We link to third-party sites and display third-party advertising. We do not control, endorse or take responsibility for that content. [IF YOU USE AFFILIATE LINKS, DISCLOSE IT HERE: state that you may earn a commission on qualifying purchases at no extra cost to the reader, and that it does not influence which products you recommend.]

No warranty and limitation of liability

This site is provided on an "as is" basis without warranties of any kind, express or implied, including accuracy, completeness, currency or fitness for a particular purpose. To the fullest extent permitted by law, we accept no liability for loss or damage arising from reliance on anything published here, including financial loss, property damage or injury. Nothing here excludes liability that cannot lawfully be excluded.

Your responsibility

Decisions about your property and your money are yours. Please use this site as one input among several, verify anything that matters against a primary source, and engage a licensed professional before buying or installing equipment.
