Do solar power systems ever pay themselves back?
The solar system will produce 100% Green Energy every sunny day. A solar power system is a long-term investment with a typical payback or around 10-15 years. However as prices go up, the payback will shorten. If the feed-in tariff comes into effect, this will also dramatically shorten the payback, perhaps as low as 6-8 years. Keep in mind that solar panels are a similar price to many other home renovations and consumer goods, which will never pay themselves back e.g. home theatre, new carpet, swimming pool, a new kitchen or even a car.
