They’re all (mostly) the same…on the outside. Solar panel technology has gotten so inexpensive that even the tightest budgets can do it. The solar panels on my roof cost about $2.50/watt ten years ago. Today I could replace every one of them for less than half that. In some cases… Read more »
A promising technology. Off Grid Ham first discussed perovskite solar cells in February 2017. This still-emerging technology uses perovskite-structured crystals to pull energy from different colors of light. Silicon panels by comparison make electricity from a narrow band of light. The process for making perovskite solar is also cheaper and… Read more »
This is a very exciting time of changes for off grid and alternative energy. The cost of established systems is coming way down and many new discoveries are in the pipeline. For sure, a lot of emerging off grid technology is highly theoretical and may never appear on the end… Read more »
