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.
Western Harmonics solar powered fan, kit #1505-HG, features a great fan running directly off a 10 Watt solar panel. Great for a variety of uses!
Get quotes from several contractors before signing any solar energy installation company. Just as with any other construction product, it pays to shop around before you commit to a particular company. Check out their reviews online and their standing with the Better Business Bureau. A little research ahead of time can save you a big headache later.
