Photovoltaics, the next in our ongoing series on renewables, appears online this week. Visit www. ajplus. co. uk/ sustainability/renewables for a review of photovoltaic technologies and a glossary of terms as well as information on how the bits and pieces fit together to make up a system; typical system outputs; and the ins and outs of grid connections.
You'll also find answers to practical questions about how to mount and orient PVC panels on buildings.
