Solar panel technology is now mature. With maturity comes cost stability. While panels are getting more efficient and inverter technology is getting smarter, the basic concept of solar power generation is still the same as it was many years ago. This means that waiting for a reduction in price is like chasing your tail – you never get there, because any possible reduction in price is no better than the expected electricity savings in the first year after installation. Therefore it's always better to take the plunge and install solar panels now rather than waiting for prices to drop. While you're waiting, you are missing out on huge power savings that could be paying off your investment.
