Actually, subsidies hold back development, since the incentive (reducing cost) to get better isn't there.

The sale price of Panels are coming down. But Panels are only part of the cost. If you want 24/7 power from solar Panels, you need to store the energy. If you are storing energy, you need batteries. Batteries are big and they are not cheap.

I just quoted an off-grid solar project for backup power. They wanted 144 x 2000 Ah x 2V batteries. My cost on those batteries was $68,000. That is 576 kWh of storage. At 90% conversion efficieny (better inverters) you'd be able to run your refrigerator, 20 CFLs, a Laptop, 42" LCD TV, for about 2.5 weeks. My house in the summer would run for about 3 days on that...
