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.
Cats say "meow" because they think that is what people sound like. This tiny ad told me so:
Switching from electric heat to a rocket mass heater reduces your carbon footprint as much as parking 7 cars
