How Much Do Solar Panels Produce in Winter? Realistic Numbers

Winter output from a rooftop solar system is a fraction of the summer peak: shorter days, a low sun, cloud and snow mean that the four darkest months together typically deliver only around a tenth to a fifth of the annual yield, depending on latitude. This guide sets realistic month-by-month expectations, explains what winter means for self-consumption and your bill, shows how a battery and smart scheduling help, and why you should never size a system for December.

Pre-Season Heat Pump Checklist: What to Check in September

A heat pump does most of its work in the coldest months, but how much electricity it burns doing so is largely decided in September. Here is what homeowners can check themselves, from the outdoor unit to the heating curve, what to leave to a qualified engineer, and how to get the most out of rooftop solar in the autumn months.

Solar PV in the Arctic: Svalbard's surprising potential

Researchers at Norway's SINTEF have found that solar PV in Longyearbyen, one of the world's northernmost inhabited settlements, can achieve capacity factors comparable to central European cities during summer. The study shows that PV, combined with wind and storage, could play a pivotal role in the Arctic energy transition.

Solar + Heat Pump: When Do They Really Cut Your Bill?

Combining rooftop solar with an air-source heat pump seems like a perfect match, but real savings depend on how well their operating hours overlap. This guide explains the key decision factors for homeowners considering both systems.
