Summary

Solar Electricity Handbook

a Simple Practical Guide to Solar Energy : How to Design and Install Photovoltaic Solar Electric Systems
If you are planning to put solar panels up, this is the most practical current advice I know of. The book is well written, and seems to tell you soup-to-nuts how to choose and size your components, whether you want to be off the grid, or tied to the grid and selling your (occasional) surplus power. The author is British, but the advice seems to be good for North America and Australia too.
