While this might have held some truth in the earlier days of solar energy adoption, prices have remained relatively stable in recent years. Solar panel performance is now so efficient that future improvements are likely to be more incremental.
It’s important to remember that pricing and efficiency are only one part of the solar investment equation. Right now, there are lucrative federal solar incentives that will decrease dramatically in the next two years. Combine these with increasing utility prices, and the real question becomes: how much money does your company stand to lose while waiting for small improvements in pricing and efficiency?
