What sort of solar? Heating water, electrical generation, what?
Please, be more specific.
I work with passive solar and some solar cooker homebuilt, and water heating. Some of that you can do yourself fairly cheaply with very little. If you are looking for electrical panels, that's different.
I have begun to write a book. I already have all the page numbers done! And one tiny ad:
GAMCOD 2025: 200 square feet; Zero degrees F or colder; calories cheap and easy
