<u><em>Solar panels don't work for every type of roof</em></u>
<u><em>Solar isn't ideal if you're about to move</em></u>
<u><em>If your electricity costs are low, so are your solar savings</em></u>
<u><em>If you can't access solar financing, up-front solar costs can be intimidating</em></u>
<u><em>High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank</em></u>
<u><em>Besides cost, the single biggest problem with solar is that the sun doesn't shine at night, and it's not guaranteed that it will shine during the day either. This causes several problems, which can be summed up in you not having power when the day ends</em></u>
