What kind of question is that? Without knowing anything about the person's geography or local cost of solar, how can you make such a bold assessment of affordability? I live in New Zealand where the capital cost of solar is very expensive and the climate is OK-not-great for solar generation. Even at 30c/kwh the payback (without batteries) is still 15 to 20 years. Not an obvious choice, especially as the capital cost is still declining.
