If you think you might need to replace your roof in the near future, hold off on installing solar panels. Solar panels can be difficult for some roof installers to contend with, and this means a more difficult and increasingly costly roof repair bill. If you can afford to wait on the panels and replace your roof first, this is the way to go.
When it comes to solar water heaters, be realistic. They're typically only 30% more efficient than any other form of water heater. Second, don't think that just because you shower in the dark means you'll have to deal with cold water. Water heated by solar power should stay warm for 24 hours.
